AI-powered low-code workflows that plan and adapt
Each task becomes a self-adaptive graph of logic, conditions, and tools that execute when their dependencies are ready and retry automatically on failure.
An LLM turns a goal into a structured, dependency-aware plan with logic you can inspect rather than an opaque chain of calls.
The engine is WASM-first, so workflows can run in the browser, at the edge, or in serverless functions.
Built-in logs, retries, and structured events make every workflow traceable and easy to debug.

Open-source workspace to build, deploy and govern AI agents
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
