Enterprise platform for building, evaluating and shipping AI agents
Design drag-and-drop workflows where each agent has a defined role, instructions, model, memory and tools, with branching logic and human handoff.
Run agents against test sets, score multiple runs per version and track regressions before anything reaches production users.
LLM-as-judge scoring and 24/7 behavioural monitoring catch hallucinations and broken tool calls while the agent is live.
Stream traces from LangChain, CrewAI, OpenAI Agents SDK, Anthropic or Google ADK into one pipeline for explainable agent decisions.
Open-source workspace to build, deploy and govern AI agents
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
