GitHub·medium signal

Sim Studio (simstudioai/sim), a YC X25 graduate, has grown to 28,600+ GitHub stars and 100K+ builders on its open-source AI agent workflow platform. The drag-and-drop visual canvas lets teams build, deploy, and orchestrate agent workflows connecting 1,000+ integrations, expose them via REST APIs, and self-host or use managed cloud. The company raised a $7M Series A led by Standard Capital with participation from Paul Graham, Perplexity, and SV Angel. SOC2 and HIPAA compliant, it's being described as the cleanest 2026-native alternative to Langflow for enterprises that want agent orchestration without vendor lock-in.
