Sim

Open-source workspace for building, deploying and monitoring AI agents and workflows, listed as integrating TypeSafe System One.

ProjectproductionApache-2.0

Overview

Sim is an open-source workspace for building, deploying and managing AI agents and workflows. It connects to over 1,000 integrations and every major LLM, including tools like Slack, Notion, HubSpot, Salesforce and databases, and can be used on the hosted sim.ai service, self-hosted with npx sim-setup or Docker Compose, or as a macOS desktop app.

The fetched README does not mention Jev. A directory listing describes native TypeSafe System One evaluation and decision provider integration, which would let workflow builders add typed decision blocks or evaluations backed by Jev alongside generative LLM steps. Details of that integration are not shown here.

How it works

  1. Build an agent or workflow in Sim
  2. Add a TypeSafe System One decision or evaluation step
  3. Route the workflow on the typed answer
  4. Monitor runs in the workspace

Strengths

  • Large integration catalogue
  • Hosted, self-hosted or desktop options

Caveats

  • Jev integration not documented in the fetched README
  • Self-hosting needs significant memory

Getting started

npx sim-setup (self-hosted) or use sim.ai.
