Open-source workspace for building, evaluating and shipping AI agents
Assemble agents from templates or from scratch, give them models, skills and tools, and run them from a chat UI, Slack or Telegram.
Wire agents into Notion, GitHub, HubSpot, Slack, Linear, Drive and more over MCP, and swap tools or skills without rewriting the agent.
Score agent outputs, collect feedback and inspect every run with duration, token usage and cost logging so improvements are measurable.
Decide which actions run unattended and which require approval, while credentials stay in a vault your agent can use but cannot read.
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.
