## How this list was made

- Candidates: the 12 AI tools, low-code, automation and API apps whose own description or topics mention AI agents, agentic workflows or multi-agent systems.
- Base score: GitHub stars on a log scale plus commits in the last 12 months (log scale, capped at 1,000).
- Bonus points for a published Docker image, an OSI-approved open-source license and a commit in the last 90 days.
- Source-available apps can rank, but they are labelled and never described as open source.
