Open-Source AI Tools Compared: Live Maintenance Data

Each comparison below puts two open-source AI tools side by side using live GitHub data: commits in the last 91 days against the same period a year earlier, last commit, stars, licence and our maintenance status. The numbers refresh automatically, so the pages stay current without anyone rewriting them.

How to read a card: the bar splits the two tools’ combined commits in the last 91 days on their default branches, and the badge is our health score out of 100. Each card opens the full comparison. We have not tested these tools ourselves; the data measures maintenance, not features or quality.
