Sim is an open source platform designed to build, test, and deploy AI agent workflows through a visual, drag-and-drop interface that simplifies complex automation processes. It provides a canvas-based environment, similar to design tools, where users can connect modular blocks representing AI agents, APIs, and integrations to create multi-step workflows without needing traditional coding skills. It supports connections to over 100 models and applications, enabling users to integrate tools like email, databases, CRMs, and calendars into unified, automated systems that can execute real business processes. Sim.ai allows users to define agents, monitor how they collaborate step by step, and view outputs in real time, making it easier to debug, optimize, and customize workflows. It also supports multiple triggers such as APIs, chat interfaces, scheduled tasks, and webhooks, enabling flexible deployment across different environments.
