"On March 31 2025, we released the REST Sandbox on a limited set of Wikis. Following the initial release, we identified (with the help of some volunteers) a few issues that prevented us from launching the Sandbox to all wikis.
The original release date for all Wikis was targeted as April 30. We are still working to resolve the outstanding issues, and it is unclear if we will be able to launch before the end of the current fiscal year. If we do not launch by the end of the fiscal year, we may consider delaying the global launch until the new version of the Sandbox (built using Codex instead of SwaggerUI) is complete."
The remaining issues include:
- Enable “Try it out” for Transform endpoints T391712: Transform "Try it out" doesn't work in REST Sandbox
- Add Endpoint descriptions T388528: Add translatable OpenAPI endpoint descriptions for all remaining endpoints
- Fix CSS conflicts uncovered by Hebrew Wikipedia T392523: REST Sandbox fails to render Hebrew parameter descriptions → requires front-end expertise
- Enable by default on all Wikimedia projects
