Reddit is adding wiki pages capability to its Developer Platform, removing a constraint that had kept moderation tools tethered to the public Data API ahead of its March 2027 shutdown.
Wiki support for Devvit apps is coming, closing a gap that currently forces some moderation bots to stay on the classic API. The addition arrives as Reddit pushes third-party developers to migrate from its public Data API to the Developer Platform (Devvit) before access begins winding down in January 2027 and ends entirely in March.
Wikis on Reddit allow moderators to create structured, persistent reference pages within their communities, used for rules, FAQs, resources, community guides, and more. Many moderation bots rely on subreddit wikis as configuration files. Tools like Banhammer.py fetch reactions from subreddit wikis, while Flair Helper 2 detects and reloads configuration changes from the subreddit's wiki page.
Without the ability to read or write wiki pages programmatically, bots built for the Developer Platform couldn't replicate workflows that have been standard on Reddit for years. That technical gap left developers with a choice: rebuild their tool's configuration system from scratch or stay on the Data API until forced off.
The wiki capability removes that dilemma. Developers porting moderation tools can now preserve the configuration patterns communities already know, rather than asking moderators to learn new systems mid-migration.
