Sim is an open-source AI workspace designed for teams that want to build, deploy, and manage AI agents in one place. Rather than forcing a single workflow, it supports three ways to create agents: visually through a block-based builder, conversationally by describing what you want in plain English, or with code for developers who prefer full control. The platform connects to more than 1,000 integrations and every major LLM, so agents can act across the tools and models a team already relies on. At the core of Sim is a semantic memory layer where data is stored in tables, files, and knowledge bases. This gives agents grounded context they can reason over, which helps improve accuracy and relevance in automated tasks. The workspace also includes built-in observability: every run is traced block by block, with full logs and real cost displayed, so teams can understand exactly how their agents behave and what each automation consumes. Sim is positioned as a production-ready solution for organizations of different sizes. It is SOC2 compliant, trusted by over 100,000 builders, and designed to scale from simple one-agent automations to many agents working in parallel. Whether the goal is automating internal workflows, connecting sales and support tools, or creating custom AI-powered processes, Sim aims to give teams a unified environment for the entire agent lifecycle.
