No-code builder for custom AI agents and workflows
Assemble agents with a drag-and-drop interface, 100+ templates, and optional code extensions when you need more control.
Connect leading models and business services so agents can reason, retrieve data, and take action across your stack.
Ship agents as web apps, browser extensions, webhook endpoints, or scheduled automations for teams and customers.
Add review steps and validation so agents produce reliable output before and after going live.

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.
