Build agents three ways
Use the workflow builder to assemble agents visually, or switch to Chat for natural-language control of your workspace, or use the API for programmatic creation and management.
Sim
Freemium
Sim is an open-source AI workspace for building, deploying, and managing AI agents with visual workflows, Chat, API access, integrations, and collaboration tools.
What is Sim?
Sim is an open-source AI workspace for teams that build, deploy, and manage AI agents in one place. It combines agent creation, workspace data, execution monitoring, and collaboration so teams can move from idea to deployed workflow without stitching together separate tools.
The product supports three creation modes: visual workflows, conversational control through Chat, and programmatic access through an API. It also connects to more than 1,000 integrations and multiple major LLM providers, letting teams build agents around existing data, apps, and tasks. The site positions Sim as a shared workspace for agent builders rather than a single-purpose chat app.
What can Sim do?
Model and integration coverage
Connect agents to 1,000+ integrations and major model providers such as OpenAI, Anthropic Claude, Google Gemini, Mistral, and xAI Grok.
Template-based workflows
Start from 11 pre-built templates for common workflows including OCR, release management, meeting follow-ups, resume scanning, email triage, and knowledge base Q&A.
Workspace data and file management
Use Tables as a built-in database for filtering, sorting, and wiring data into workflows, and Files as a shared store for documents, spreadsheets, and media.
Execution logging
Track each run with Logs, which show execution inputs, outputs, cost, and duration for visibility into workflow behavior.
Team collaboration
Work in a shared workspace with real-time multiplayer collaboration, including live cursors, presence indicators, concurrent editing, and role-based access control.
Use Cases
“Operational workflow automation”
Build an internal agent that pulls from connected apps, processes data, and runs repeatable workflows with a mix of models and integrations.
“Fast-start template deployment”
Use the pre-built templates to launch common automations such as invoice OCR, email triage, meeting follow-ups, or competitor monitoring without starting from a blank slate.
“Collaborative team building”
Let a product, ops, or engineering team co-build agents in a shared workspace with live editing, presence indicators, and role-based access.
“Model selection and comparison”
Centralize model selection by comparing providers and model capabilities in the directory before wiring a workflow to the right LLM.
“Run monitoring and iteration”
Monitor workflow behavior by reviewing logs for inputs, outputs, duration, and cost when iterating on agent performance.
Frequently Asked Questions
What is Sim used for?
Sim is designed for building, deploying, and managing AI agents in a shared workspace. The source shows teams can use it with Chat, the workflow builder, or the API.
How do you build agents in Sim?
The source shows three main ways to work: build visually with the workflow builder, converse through Chat, or create agents programmatically with the API.
Does Sim include starter templates?
The homepage says Sim includes 11 pre-built workflow templates covering tasks such as OCR processing, email triage, meeting follow-ups, resume scanning, and knowledge base Q&A.
What does Sim pricing look like?
The pricing page text shows a free Community plan, paid Pro and Max plans, and a custom Enterprise plan. The page also lists CLI, SDK, and MCP access across plans.
Can teams use Sim together?
The source does not provide a full setup guide, but it does indicate Sim is a shared workspace with collaboration features such as live cursors, presence indicators, role-based access control, and team workspace management.
