How a Reddit Wiki Works, Who Can Edit It, and What to Read Before You Post

What is a Reddit wiki?

Every subreddit can switch on a Reddit wiki, a set of reference pages at /r/<subreddit>/wiki where moderators keep extended rules, FAQs, guides and resources that don't fit in the sidebar. Reddit's help article on wikis for your communities defines them in one line: "Wikis on Reddit allow moderators to create structured, persistent reference pages within their communities. They can be used for rules, FAQs, resources, community guides, and more."

The wiki belongs to the community, not to Reddit. Each subreddit's moderators choose whether it exists, which pages it has, who can edit them and whether readers see them at all. Reddit's sitewide guidance lives elsewhere: the help centre now hosts reddiquette, which used to be a wiki page itself.

Where do you find a subreddit's wiki?

Open the community and select the Wiki tab, or go straight to https://www.reddit.com/r/<subreddit>/wiki/index. Reddit's help article says the wiki is reachable "via the Wiki tab on your community page (available on both desktop and mobile)." The index page is the wiki's front page, which the help centre describes as "your homepage for your wiki."

URL or tool	What it returns
/r/<subreddit>/wiki/index	The landing page, with links to the other pages
/r/<subreddit>/wiki/<page>	A named page, such as a rules or FAQ page
/r/<subreddit>/wiki/<parent>/<page>	A page nested under a parent page
Wiki menu on the left	Every page the mods list in the wiki index
GET /r/<subreddit>/wiki/pages (Data API)	A list of the subreddit's wiki pages, under the wikiread scope
GET /r/<subreddit>/wiki/revisions (Data API)	Recently changed pages, under the same scope

Moderators choose the page names, so start at the index instead of guessing a URL. A page can also be unlisted. The help centre says an unlisted page is hidden from the wiki menu, and "you will need the link in order to access it." When a moderator shares a link, Reddit tells them to copy it from the page's overflow menu, because a URL copied from the address bar can carry "/about," and then "non-mods won't be able to view the page."

Logged-out reading works on reddit.com. On 9 October 2026 we opened the r/startups wiki without an account and the page loaded. The same wiki on old.reddit.com redirected to a login page, since Reddit now requires an account for old Reddit.

Who can edit a Reddit wiki?

Moderators decide who can edit a Reddit wiki, in the wiki's global settings and again per page. The help article lists six levels a community can choose from:

1. Moderators only.
2. Approved contributors, users the mods add one by one.
3. Top contributors, defined as "users in the top 10% of posters/commenters" in that community.
4. Users who meet the karma or account-age minimums the mods set.
5. "Anyone who has successfully posted or commented in the community within the past year."
6. Anyone at all.

Page settings override the global ones in one direction. A moderator can set a single page to "Mods only," and it stays mod-only "even if global settings are set to Anyone." Bans carry over too: "If a user is banned from your community, they lose wiki edit access too." Top contributors and recent commenters face a brake too, because the help centre says they "may encounter a waiting period of at least 5 minutes between edits," and some wikis apply Contributor Quality Scores to keep spam accounts out.

Old wikis show these limits in the page text. The r/Entrepreneur wiki index, last revised 11 years before our visit, still invites readers to "Edit this wiki! (> 100 karma, > 30 days)."

Why should you read the wiki before posting?

The wiki is where moderators put the rules that don't fit in a sidebar, so reading it is the fastest way to learn what gets a post removed. Reddit's Wiki wisdom article, written from moderators' advice, says "wiki pages that explain rules and submission guidelines can reduce the amount of rule violations and cut down on repetitive questions." It recommends that mods include "examples of rule-breaking posts and edge cases," explain the flair system and gather a community FAQ.

That is the information an outsider needs most. Reddit's help centre lists "extended rules or participation guides" among the main uses of a wiki, and that is where details such as a disclosure format or a weekly promotion thread end up. The same help article tells would-be wiki editors to "review any specific karma, account age, or posting requirements the moderators have set," and those thresholds are explained in the guide to Reddit karma requirements. If you plan to mention your own product, read the wiki next to the community's self-promotion rule before you write a word.

Before posting in a new community, work through this order:

1. Read the sidebar rules on reddit.com, which moderators edit directly.
2. Open the Wiki tab and the index page, and look for rules, FAQ or posting-guideline pages.
3. Check the "Last revised" line at the bottom of each page you rely on.
4. Read the pinned posts, which carry recent rule announcements and recurring threads.
5. Search the community for your question, since a FAQ page exists to stop repeats.
6. Message the moderators through modmail if the rules and the wiki disagree.

What if a subreddit's wiki is disabled or out of date?

A disabled or stale wiki tells you to rely on the sidebar rules and pinned posts instead. We checked three communities that founders post in on 9 October 2026. The r/SaaS wiki returned "This wiki has been disabled. The mods of this community have disabled their wiki." The r/startups index loaded, but its footer read "Last revised by julian88888888 6 years ago." The r/Entrepreneur index was last revised 11 years ago and links only to a FAQ and a resources page.

So check the date before you treat a wiki page as the rule. Each page has a version history, and the new wiki system added "public version history" with "full attribution and timestamps." When a page from years ago conflicts with the current sidebar, follow the sidebar and ask the mods.

What changed with Reddit's new wiki system?

Reddit rebuilt its wikis with in-line editing, templates, embedded media and auto-generated tables of contents, and moved new communities onto the new system from 12 August 2025. The help article says "all new communities, or communities just creating a wiki for the first time, will be migrated to the new wiki system," and warns that "edits on old.reddit won't sync to the new system post-migration." AutoModerator's configuration page is the exception: "Automod config pages are excluded and will continue syncing across versions."

Two older rules still hold. "Wiki pages cannot be deleted," so moderators blank a page or hide it from the index instead. And the table of contents and anchor links "don't work in the Reddit app," so a long wiki reads better on desktop.

How does RedReplier handle subreddit rules?

RedReplier puts posting rules next to the communities it suggests, so you see the rule before you write the reply. Its subreddit suggestions read what you sell, rank matching subreddits by fit, and flag each one with its posting rules, showing an ok-to-post badge or an avoid badge "with the exact rule behind it." That saves reading ten wikis to find the two communities where a vendor answer is welcome.

For the conversations themselves, RedReplier monitors Reddit, X, Bluesky, Facebook and Hacker News for your keywords and ranks each match by buyer intent. Matches land on your RedReplier dashboard within minutes of a post or comment going live, and email alerts go out as digests on a cadence you set per keyword, from hourly to daily. RedReplier drafts a reply, and you check the community's rules and wiki, edit the draft and post it yourself.

Frequently asked questions

How do I find a subreddit's wiki?

Open the community and select the Wiki tab, or visit reddit.com/r/<subreddit>/wiki/index. The index page links to the other pages, and the menu on the left lists every page the moderators show in the wiki index. Unlisted pages need a direct link.

Can anyone edit a Reddit wiki?

Only if the moderators allow it. They choose between mods only, approved contributors, top contributors, users who meet karma or account-age minimums, recent participants, or anyone. A single page can still be locked to mods even when the rest of the wiki is open.

Why can't I edit a subreddit wiki?

Editing is limited by the community's settings, and Reddit lists these causes: you are not an approved or top contributor, you don't meet the karma or account-age minimum, a wait of at least 5 minutes between edits applies to top contributors and recent commenters, or your account fails the community's quality checks. A ban from the community also removes wiki edit access. Ask the moderators through modmail if none of these fit.

Can a Reddit wiki page be deleted?

No. Reddit's help centre says "wiki pages cannot be deleted." Moderators repurpose the page, replace its text with a note, or hide it from the wiki index, after which the page is reachable only by its link.

Why does a subreddit's wiki say it has been disabled?

The moderators turned the wiki off in the community's wiki settings. A disabled wiki shows "The mods of this community have disabled their wiki" and a link back to the community. Read the sidebar rules and pinned posts for the posting guidelines instead.

Do I need an account to read a Reddit wiki?

Not on reddit.com, where public wiki pages loaded for us without logging in on 9 October 2026. Old Reddit is different: since July 2026 it requires an account, so old.reddit.com wiki URLs redirect logged-out visitors to a login page.

Where do I find the last revised date on a Reddit wiki page?

Look at the footer of the page. On the r/startups index it read "Last revised by julian88888888 6 years ago." The new wiki system also keeps a public version history with full attribution and timestamps.

What should I do if a subreddit's wiki and sidebar rules disagree?

Follow the sidebar rules, because moderators edit them directly and some wiki pages are years old. Check the "Last revised" line on the wiki page first. If the conflict is still unclear, message the moderators through modmail before you post.

Do edits on old Reddit sync to the new wiki system?

Not after a community migrates. Reddit's help article warns that "edits on old.reddit won't sync to the new system post-migration." AutoModerator config pages are the exception and keep syncing across versions.

Why can't I see a wiki page in the menu?

Moderators can leave a page unlisted. An unlisted page is hidden from the wiki menu, so you need its direct link to open it. A link copied from the address bar can carry "/about," and Reddit says that makes the page unviewable for non-mods.
