What do I get?
A hosted Thoughtbox workspace connected to your MCP clients. Your agents record structured reasoning traces that you can inspect, replay, and analyze in the dashboard.
What MCP clients are supported?
Thoughtbox is optimized for Claude Code. It also works with Cursor and VS Code via MCP configuration. We're actively expanding client support.
What does “founding beta” mean?
The product is early and actively evolving. You get direct access to the team, your feedback shapes the roadmap, and you'll be grandfathered into favorable pricing when we move to general availability.
What's the difference between hosted and self-hosted?
Same product. The founding beta gives you a managed workspace, onboarding support, and a direct line to the team. Self-hosting is free forever — you run the Docker container and manage your own data.
