Claude

- +Open MCP Connectors wire it into Gmail, Workspace, Slack, Jira, and Zapier

- -Most of the product is assistant/copilot grade; the agentic modes are newer and narrower
- -Cowork ships as a research preview and (for now) on the desktop app
Sim
- +Genuinely open-source (Apache 2.0) with first-class self-hosting via Docker, npm, and local models (Ollama, vLLM)
- +Broad model and integration coverage plus multiple deployment modes (API, chat, schedule, webhook, MCP server)
- +Strong momentum: YC-backed with a Series A and tens of thousands of GitHub stars
- -Young company (founded 2025) with a small team and limited enterprise support track record
- -Paid cloud tiers are credit-metered, making costs harder to predict for heavy workloads
