A catalog of ChatGPT & Codex plugins, sorted by people.
We list 38 plugins released under Apache-2.0, about 11% of our 346-plugin catalog. They're ordered by editor's picks, then GitHub stars (checked 2026-10-27). The median one has 7 stars, and 34 of them got a push in the last 30 days.
Most-starred: Remove AI Watermarks, Sno Station Skills, AgentOps. Biggest shelves here: Agent Workflows (10), Memory & Context (8), Miscellany (6).
Apache-2.0 is permissive like MIT, but it also includes an explicit patent grant and asks you to note changes you make.
Stars measure popularity, not quality or safety. Descriptions are each project's own. Read the code before you install anything.
Other licenses: MIT (268)
Identify and remove AI watermarks and provenance metadata (Gemini and Veo marks, SynthID, C2PA, EXIF) in images and video you generated yourself, plus provenance metadata in audio.
