You can build a member-edited wiki on WordPress with a wiki plugin that lets logged-in members create and edit pages from the front end, keeps a revision history of every change, and lets moderators roll back bad edits. WB Member Wiki, made by Wbcom, does this on its own or alongside BuddyPress, BuddyBoss or PeepSo. Yada Wiki is a lighter option. Documentation plugins such as Echo Knowledge Base and BetterDocs suit staff-written help centres better than open editing.
Everything below was checked against each product’s own pages in October 2026. Wbcom makes WB Member Wiki and Reign, so read that part with the right amount of salt. The other tools get their real strengths too.

What is a member-edited wiki, and how is it different from a knowledge base?
A member-edited wiki is a set of pages that your members write and improve together, where every change is saved so it can be reviewed or undone. A knowledge base is a set of articles that a small team writes for everyone else to read.
The difference is who holds the pen. In a knowledge base, a support lead writes “How to reset your password” and nobody else touches it. In a wiki, a member who found a faster way to reset it can fix the page themselves, and the next member benefits.
That sounds like a small distinction. It changes almost every decision you make: the permissions, the moderation, how pages are named, even how you measure success.
Wikis fit communities that hold knowledge worth sharing. Think of a gardening group with a plant database, a game guild with strategy pages, a professional association with a glossary, or a software user group with tips the official docs never cover. If your members mostly ask questions and get answers, you may want a Q&A format instead, and we cover that in our guide to building a Q&A site on WordPress with accepted answers and voting. If you need a place for open conversation first, start with the options in best WordPress forum plugins. A wiki works best next to those, as the place where the settled answers end up.
Which WordPress wiki plugin should you use?
Use a front-end wiki plugin with revision history and a review queue if members will edit; use a documentation plugin if staff will write; use MediaWiki only if you want a separate system and can run it. Each of the options below is real and in use.
WB Member Wiki
WB Member Wiki is Wbcom’s wiki plugin, and it is the one built around member editing. According to its product page at store.wbcomdesigns.com/wordpress-wiki-plugin, members create and edit pages from a front-end form without going into wp-admin. Every save is a revision. Members can see who changed a page and when, compare a revision against the current page side by side, and restore an older version.
Other features on that page: [[Page Title]] links between pages (links to pages that do not exist yet show in red and open the create form), parent pages with breadcrumbs, Wiki Categories and Wiki Tags, a collapsible contents box, edit locking so two people do not overwrite each other, auto-save, a Recent Changes list, per-member Contributions, a watchlist that emails members when a watched page changes, and search suggestions as members type.
It works with BuddyPress, BuddyBoss and PeepSo, adding a Wiki tab to member profiles when one of them is active. It also runs in standalone mode without any of them. The page lists importers for MediaWiki (XML), Notion and Confluence. Published wiki pages are public and output TechArticle and breadcrumb schema, Open Graph tags and a canonical URL. For licence terms, number of sites and pricing, check the product page.
Its limits, stated on the same page: you can compare a revision only against the current page, not two old revisions with each other; revisions are pruned to 25 by default (you can raise the limit); and the history screen lists up to 50 entries at a time without pagination. Pages are not written in wikitext. The only added syntax is the double-bracket link.
Yada Wiki
Yada Wiki is a lighter plugin that adds a wiki post type with its own tags and categories. Its page at wordpress.org/plugins/yada-wiki shows a toolbar button that inserts a shortcode to link to another wiki page, another that outputs a contents page, a category list or an index grid, sidebar widgets for recent articles, and red styling for links to pages that do not exist yet for users who can edit. It lists 2,000+ active installations.
On permissions, the page says that since version 2.1.0 roles have the same edit abilities for wiki articles as for regular posts. That means you manage who edits through ordinary WordPress roles. The page also says the plugin is not compatible with WordPress multisite, and that the block editor is off on wiki pages by default, with an optional setting to turn it on.
The page does not mention revision history, a review queue or a front-end editing form. That does not prove they are missing, but test them on a staging site before you promise anything to your members. Yada Wiki is a good pick for a small, mostly staff-curated glossary. For an open, member-edited wiki, you will probably want more control than it describes.
Echo Knowledge Base and BetterDocs
These are documentation plugins. They are good at what they do, and what they do is publish help articles that a team writes.
Echo Knowledge Base, per its page at wordpress.org/plugins/echo-knowledge-base, offers an AJAX search bar, categories up to five levels deep, breadcrumbs, a table of contents, a glossary, article quizzes and a view counter. It has a front-end visual editor, but that is for laying out the knowledge base pages, not for members to write articles. The page lists granular content protection by user group or role, and describes it under its paid features. Its page does not mention revisions.
BetterDocs, at betterdocs.co, describes live search as people type, an internal knowledge base with role-based access for private docs, and, in its paid part, multiple knowledge bases and analytics covering content gaps, stale content and link health. Its page does not mention front-end editing.
If your plan is “our support team writes the help centre”, either is a sound choice, and the stale-content analytics in BetterDocs is a real advantage there. If your plan is “our members write the wiki”, neither page describes the tools you need most: member editing and an edit trail.
MediaWiki as a separate system
MediaWiki is the software behind Wikipedia. Its manual describes it as free server-based wiki software under the GNU General Public License, built for large sites, using wikitext so that editors do not need to know HTML. Each edit is saved while earlier versions are kept, which makes it easy to revert vandalism or spam.
Its permission system is the most mature of any option here. Rights are bundled into groups. By default, the sysop group can delete and restore pages and block users; only sysops hold the protect and rollback rights; and the autoconfirmed group is granted automatically once an account is old enough and has made enough edits. All of this comes from the MediaWiki user rights manual.
The cost is that it is a separate application. It runs on PHP with its own database, has its own login unless you connect the two, and does not share your WordPress theme, member profiles or notifications. The manual also notes that MediaWiki is often a poor fit for restricting access to parts of a wiki. Choose it when the wiki is the product and you have someone to maintain it. Choose a WordPress plugin when the wiki is one room in a community that already lives on your site.
How do the wiki options compare?
The table lists only what each product’s own page says. A dash means the page does not mention it, not that the feature is missing.
| Option | Members edit on the front end | Revision history | Review queue / protection | Best for |
|---|---|---|---|---|
| WB Member Wiki (Wbcom) | Yes, front-end form | Yes, compare to current and restore | Pending Review queue for moderated roles; page protection | Member-written wikis, with or without BuddyPress, BuddyBoss or PeepSo |
| Yada Wiki | Uses ordinary WordPress roles and editing | - | - | Small, lightly managed wikis and glossaries |
| Echo Knowledge Base | Front-end editor is for page layout | - | Role-based content protection (paid part) | Staff-written help centres with deep categories |
| BetterDocs | - | - | Role-based access for internal docs | Staff-written docs with search and analytics |
| MediaWiki | Yes, wikitext editing | Yes, earlier versions kept | Groups, protect and rollback rights | A standalone wiki where the wiki is the whole site |
Whichever you pick, the rest of this guide applies. The habits that keep a wiki healthy matter more than the plugin.
How do you set up a wiki your members can edit?
Set it up in six steps: decide the scope, install the plugin, set roles, create the first pages yourself, invite a small group, then open it up. The steps below use WB Member Wiki as the example because it is the one built for this job, but the order works for any plugin.
Step 1: Decide what the wiki is for
Write one sentence: “This wiki holds ____ so that members can ____.” A sentence like “answers to the setup questions new members keep asking, so they stop asking in the feed” is specific enough to guide every later choice. “Everything about our community” is not.
To confirm it worked, show the sentence to two members and ask what they would expect to find. If they name pages you had not planned, adjust the scope.
Step 2: Install the plugin and the front page
Install the wiki plugin on a staging copy first if your site is live. WB Member Wiki lists WordPress 5.8 and PHP 7.4 as minimum versions on its product page. On a site without BuddyPress, BuddyBoss or PeepSo it runs in standalone mode and uses a Wiki Dashboard page that it creates on activation.
That dashboard is your wiki’s front door. Per the product page it links to Recent Changes, Categories, Random Page, My Watchlist and Pending Review, and filters by category and by last modified or views.
To confirm it worked, open the dashboard while logged out and check what a visitor sees.
Step 3: Set roles before anyone writes
Rights in WB Member Wiki are set per WordPress role for creating pages, editing others’ pages, deleting and protecting. Decide these now, because changing a permission after members have started writing is far more awkward than choosing it first. The next section covers what to choose.
To confirm it worked, log in as a test account in each role and try to edit a page. Do this with a real test user, not by reading the settings screen.
Step 4: Write the first ten to twenty pages yourself
An empty wiki looks abandoned, and members will not know what a good page looks like. Write the pages that answer your most common questions, use the same headings on each, and link them to each other. These pages are your style guide by example.
To confirm it worked, ask someone who has never seen the community to find an answer using only the wiki.
Step 5: Invite a small group first
Pick five to ten of your most active members, show them how to edit, and ask them to improve existing pages rather than start new ones. This is the same approach we describe in our guide on how to launch an online community and get your first 100 members: start with a few people who care, then widen the circle.
To confirm it worked, open Recent Changes after a week. You want to see edits from several people, not one person doing everything.
Step 6: Open it to the wider membership
Announce it in the community feed, pin the link, and point to two or three good example pages. If you moderate new contributors at first, say so in the announcement so a pending page is not a surprise.
To confirm it worked, check that a brand-new member can create a page and see it land where you expect, whether live or in the review queue.
Who should be allowed to edit?
Let trusted members edit anything, send new members’ pages through review, and protect the handful of pages that must never change. That is the whole model, and every plugin on this list can approximate part of it.
Here is how it maps in WB Member Wiki. The product page says admins can always edit others’ pages, and that other roles can do so only if “Edit Others’ Pages” is enabled for them. Moderated roles submit pages to a Pending Review queue until an editor approves them. Protected pages can be edited only by the member who protected them and by site admins.
That gives you three practical tiers:
- New members. They can create pages, but the pages wait in Pending Review. They cannot edit others’ pages yet.
- Established members. They can create pages directly and edit other people’s pages, with every change logged in the history.
- Staff and moderators. They approve queued pages, restore old revisions and protect pages such as house rules.
How do members move up a tier? The product page describes rights per role, so the simplest approach is to assign a role such as “Wiki Editor” by hand, or through whatever rules your membership setup already uses. MediaWiki automates this with its autoconfirmed group, which members join once their account is old enough and has enough edits. If you want that kind of earned trust on WordPress, you can link it to your community’s levels. Our guide to WordPress gamification plugins covers ways to turn activity into ranks, and WB Gamification is Wbcom’s option for points, badges and ranks. Check its product page to see how a rank could map to a role on your site.
A warning: the people who make the most edits are not always the people who make the best ones. Give edit rights for proven care, not just volume.
How do revision history, moderation and rollback work?
Revision history saves a copy of the page at every edit, moderation decides which edits go live, and rollback puts an earlier copy back. Together they let you be generous with edit rights, because any mistake can be undone in seconds.
Revision history
In WB Member Wiki each save is a revision. A page has a History action next to Edit, Watch and Protect. Members can see who changed a page and when, and compare any revision against the current page in a line-by-line side-by-side view. Two limits are worth knowing before you promise anything: comparisons run only between one revision and the current page, and revisions are pruned to 25 by default. For a busy page, raise the limit in settings, otherwise your trail of edits gets shorter than you expect.
To confirm it worked, edit a test page three times, open History, and compare the first revision with the current one.
Moderation
Wiki moderation is quieter than forum moderation. You are mostly checking pages, not breaking up arguments. Use the Pending Review queue for new contributors and Recent Changes for everyone else. Check Recent Changes once a day on a small site; on a larger one, ask two or three trusted members to share the job.
Edit wars, where two members keep reversing each other, are a human problem, not a software one. When you see one, protect the page, talk to both people, and decide what the page should say. For the people side of this, including warnings and what to do about repeat offenders, read our community moderation guide for WordPress.
Rollback
Rollback means restoring the last good version. The product page says anyone who can edit a page can restore an older version. That is convenient and also a point to think about: if every editor can restore, a bad actor with edit rights can restore the wrong version too, and the history will show who did it.
MediaWiki handles this by making rollback a separate right that, by default, only sysops hold. WB Member Wiki ties restoring to editing, so the safeguard is the Pending Review queue for new accounts and the history for everyone else.
A simple rollback routine:
- Open the page’s History.
- Find the last revision you trust and compare it with the current page.
- Restore it.
- Message the member who made the bad edit, with a link to your editing rules.
- If the same person does it again, remove their edit rights.
To confirm it worked, reload the page as a visitor and check the restored text is live.
How should you structure and name wiki pages?
Name pages the way a member would search for them, use parent pages for grouping, and keep each page about one thing. Structure is the part of a wiki that is hard to fix later, so spend an hour on it now.
Some rules that hold up well:
- Use plain, singular titles. “Repotting a monstera” beats “Monstera repotting tips and tricks 2026”. The first will still be right in two years.
- One topic per page. If a page needs more than a screen of scrolling and three unrelated headings, split it. The contents box in WB Member Wiki appears when a page has three or more headings, which is a handy prompt to ask whether the page is doing too much.
- Use categories for browsing, tags for cross-cutting ideas. WB Member Wiki has Wiki Categories and Wiki Tags, and also parent pages with breadcrumbs. A reasonable split: categories for the main sections (Getting started, Rules, How-to), tags for things that cut across them (beginner, tools, troubleshooting).
- Write a naming guide as a wiki page. Put it first, protect it, and link to it from the editing form’s help text.
- Keep the tree shallow. Two levels of parent pages is plenty for most communities. Echo Knowledge Base allows categories five levels deep, which is useful for a large documentation set, but a member-edited wiki rarely needs it.
How do you make wiki search and internal links work?
Good search finds the right page from a half-remembered word, and good internal links let a reader move through related pages without searching at all. A wiki needs both.
Search
WB Member Wiki shows suggestions as members type and offers category chips to narrow the page list. The Wiki Dashboard also filters by category and sorts by last modified or views. BetterDocs describes live search as people type, and Echo Knowledge Base describes an AJAX search bar, so all three give readers quick results on their own pages.
Two practical points. First, write page titles and the first sentence with the words members actually use. If members say “kick” but your page says “remove participant”, search will fail them. Second, watch what people search for and do not find. If your plugin does not report this, ask members in the feed what they could not find. The gaps are your next pages.
To confirm it worked, give three members a question each and see whether they reach the page in under a minute.
Internal links
Link generously. In WB Member Wiki you type the page title in double brackets, such as [[House rules]], and the link is made for you. A link to a page that does not exist yet shows in red and opens the create form, so a member who spots a missing topic can fill it in on the spot. Yada Wiki also shows links to missing pages in red for users who can edit.
That red link is one of the best habits a wiki has. It turns every gap into an invitation.
Aim for every page to link to at least two others, and for every page to be linked from at least one. A page nobody links to is invisible, whatever the search says. Review Recent Changes and the category lists now and then for these orphans.
Search engines can index published wiki pages in WB Member Wiki, which the product page says output TechArticle and breadcrumb schema, Open Graph tags and a canonical URL. If you want your public wiki to bring in visitors from Google, that is useful. If parts of your wiki should stay members-only, decide which before you launch and check with a logged-out browser.
How do you stop wiki pages going stale?
Assign every page a reason to be revisited, and make staleness visible. Pages go stale because no one owns them, not because the topic changed.
Practical steps that cost little:
- Show the last modified date. WB Member Wiki has display settings for the contents box, contributors, last modified date, revision count and view count. Turn on the last modified date, so readers can judge for themselves.
- Use watchlists. Members can watch a page and receive an email when it changes. Encourage the person who wrote a page to watch it. They are the most likely to notice when it is wrong.
- Run a quarterly review. Sort the dashboard by last modified, oldest first, and check the top twenty pages. Fix, merge or delete.
- Lean on view counts. A page with many views and no edits in a year is more urgent than a page nobody reads. Use the view count display to find them.
- Name page owners for the critical pages. A rules page or a setup guide should have a named person who checks it.
- Delete without guilt. A wrong page is worse than a missing one. Remove outdated pages, or redirect readers to the page that replaced them.
How does a wiki fit into a Reign community site?
The wiki sits inside your normal site design, so members see the same header, colours and navigation as everywhere else. That keeps it feeling like part of the community, not a separate corner.
Reign is Wbcom’s community theme. It offers five header layouts, custom colour tokens and dark mode with no code edits. WB Member Wiki’s product page says the wiki renders inside your active theme and works with any theme, and that you can change its markup by copying a template into yourtheme/wb-member-wiki/ in the theme folder. Whether you use Reign or another theme, test the wiki pages on a phone and in dark mode before you open them up.
A layout that works well for most communities:
- Put “Wiki” as a top-level item in the main menu, next to the feed and member directory.
- Pin a link to the wiki in your welcome post and in the onboarding emails.
- Add the Wiki Dashboard to the landing experience for new members, since it is the page with Recent Changes, Categories and the watchlist.
- Link wiki pages from forum or Q&A answers, so settled questions point at the page that holds the answer.
If your community runs on BuddyNext, BuddyPress, BuddyBoss or PeepSo, the wiki can add a Wiki tab to member profiles; for WB Member Wiki the product page names BuddyPress, BuddyBoss and PeepSo, so check the product page for your exact setup. With a members-only directory you might also add searchable profiles, which our guide to member directory plugins for WordPress covers, so members can find the person who wrote a page and ask a follow-up question.
Reign’s own pages list the range of sites it supports, from forums to course sites and job boards. See what you can build with Reign for the full picture, and how to install Reign and import a demo if you are starting from nothing.
Questions people ask
What is the best WordPress wiki plugin?
It depends on who writes the pages. For a wiki that members edit, with revision history and a review queue, WB Member Wiki is built for that job, and Wbcom makes it. Yada Wiki is a simpler option for small wikis. For staff-written help centres, Echo Knowledge Base and BetterDocs are better fits.
Can I make a wiki on WordPress without BuddyPress?
Yes. WB Member Wiki’s product page describes a standalone mode that works without BuddyPress, using a Wiki Dashboard page created on activation. Yada Wiki is a plain WordPress plugin and does not need a community plugin either.
How do I undo a bad edit?
Open the page’s history, compare the last good revision with the current page, and restore it. Note that in WB Member Wiki revisions are pruned to 25 by default, so raise that limit for pages that change often. Then tell the member what went wrong, and use page protection if it keeps happening.
Is a knowledge base the same as a wiki?
No. A knowledge base is written by a team for readers; a wiki is written by its readers. You can run both: a staff-written help centre for official answers and a member wiki for the tips the official docs never cover.
Should I use MediaWiki instead of a WordPress plugin?
Use MediaWiki if the wiki is the whole site and you have someone to maintain a separate PHP and database application. Use a WordPress plugin if the wiki is one part of a community, because members keep one login, one profile and one theme.
Where to go from here
Start small: pick a plugin, write twenty pages yourself, invite ten members, and widen the circle once the habit sticks. If you would like the wiki to sit in a community with a design members enjoy using, see the Reign theme page, and look at the WB Member Wiki product page for licence terms and the current feature list.
