Sim is an open-source (per its own GitHub repo, simstudioai/sim) low-code/no-code platform for composing AI agent workflows - trigger blocks, agent blocks backed by any major LLM, custom tools, MCP tool consumption, and structured data (Tables, Knowledge Bases, Files) - deployable via its own cloud, self-hosted infrastructure, API, or chat.
Technical teams that want to build and operate multiple internal AI agents/workflows without building bespoke orchestration and observability tooling, and want the option to self-host for compliance reasons.
The Free plan caps monthly execution credits at 1,000, one workspace, 10 concurrent executions, and a 5-minute sync timeout - teams running many or long-running workflows will hit these limits quickly and need to move to Pro ($25/user/mo) or Max ($100/user/mo). Enterprise-only features - SSO, SOC2 compliance, and self-hosting support - are gated behind custom Enterprise pricing, so regulated teams needing those controls can't get them on a self-serve plan. Sim Mailer and KB Live Sync are absent on Free and Pro, appearing only from Max upward.
Yes.
Yes, a 'Free forever' plan with 1,000 monthly execution credits (daily refresh), one workspace, and 5 GB of file storage.
Yes - the docs describe 'Using MCP tools' as an agent capability and list an MCP deployment option alongside API and Chat deployment.
The integrations page lists 233 apps and services across categories like Sales, DevOps, Productivity, Databases, and Communication; marketing copy elsewhere on the site rounds this up to '1,000+ integrations.'
