Visual agent workflows\, open source underneath.
Sim Studio builds AI agent workflows on a canvas — chaining models\, tools and logic — with a public repository that has drawn around 30k GitHub stars.
That open-source traction matters practically: an active community means more integrations and faster fixes than a closed product of the same size. The free tier gives 1\,000 one-time credits and 10 concurrent executions\, enough to build something genuine.
