Sim
A collaborative workspace for building, deploying and monitoring AI agents and workflows, connecting more than 1,000 integrations and every major LLM through a visual, conversational or code-based builder.
Sim keeps chat, workflows, file storage, structured tables and a knowledge base for agent memory in one workspace, accessible from a browser or a macOS desktop app, and lets a team build agents visually, conversationally or with code while monitoring runs, logs, schedules and workflow activity. It connects to services such as Slack, Notion, HubSpot and Salesforce alongside databases and every major LLM provider, including local models through Ollama and vLLM.
It is available as a cloud-hosted service, or self-hosted with an interactive npx sim-setup wizard that provisions a database, generates secrets, connects a chat API key, and starts the published Docker images; a cloned repository additionally unlocks source-based local development and Kubernetes deployment modes. It is built on Next.js and Bun, with PostgreSQL and Drizzle ORM, Better Auth for authentication, and E2B for remote code execution.
