AI Agent Platforms

Build and run AI agents that handle recurring work for you.

Self-hosting has no license fee; you pay for infrastructure and model providers. The hosted Platform is paid with usage-based runs. Platform code uses Polyform Shield for personal/internal business use; classic components are MIT, so the whole platform should not be described as MIT open source.
