Sim
Sim is an open-source AI workspace to build, deploy and govern AI agents with centralized integrations, per‑run logs, access controls, and optional self‑hosting. Inputs are agent configs, data and integrations; actions include runs with trace logs; outputs are deployed agents plus execution and cost logs.
Sim documents four plans: Free ($0, free forever), Pro ($25 per user/month, billed monthly), Max ($100 per user/month, billed monthly), and Enterprise (custom, talk to sales). The pricing page lists included credits, concurrency, storage and feature differences per plan.Is Sim right for you?
Good for
- Engineering or ML ops teams that need a collaborative workspace to run multiple integrated agents with audit logs and optional self‑hosting.
- Centralized agent build and deployment across visual, chat, and code interfaces.
- Traceability: per-run logs that record run blocks, actions, cost, and failures.
Keep in mind
- Paid plans are priced per user and billed monthly, which scales cost directly with headcount.
- Enterprise capacity and pricing require direct sales contact rather than published fixed rates.
- If you need a headcount‑agnostic seat model, confirm pricing impact: Sim’s published paid plans are per‑user and billed monthly.
