Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 11, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 19% of issues opened in the past year have never received a reply. 100% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. 77% of tracked open issues have had no activity in three months, so the open count overstates what is actively being worked. Only 32% of issues opened in the past year have been closed. Three people close 65% of everything that gets resolved.

Detailed Description

cat-catch is a browser extension that intercepts and captures network resources loaded by web pages.

The extension works by monitoring network traffic as you browse and identifying media files, particularly video streams and m3u8 playlists, that are being loaded by websites. It displays these resources in a panel where you can preview and download them. This approach allows you to capture content that may not be directly downloadable through standard browser save functions, including streaming video that uses adaptive bitrate protocols.

The tool suits developers and users who need to download video content from websites where direct download options are unavailable or obscured. It works as a Chrome and Firefox extension, making it accessible across major browsers. The extension is particularly useful for capturing m3u8 streams and other video formats that load dynamically through network requests rather than as static files on the page.

Development activity on the project shows consistent engagement with bug fixes and feature improvements addressing user-reported issues. The maintainer responds to issues and implements changes based on user feedback. Updates address both core functionality refinements and compatibility adjustments for browser changes.
