Hey HN. I'm David, solo dev, 20+ years shipping production systems. I built Tesseract because AI can analyze your codebase, but the results stay buried in text. Architecture is fundamentally visual — you need to see it, navigate it, drill into it. So I built a 3D canvas where AI can show you what it finds.

Tesseract is a desktop app today (cloud version coming) with a built-in MCP server. You connect it to Claude Code with one command:

  claude mcp add tesseract -s user -t http http://localhost:7440/mcp

I use it for onboarding (understand a codebase without reading code), mapping (point AI at code, get a 3D diagram), exploring (navigate layers and drill into subsystems), debugging (trace data flows with animated color-coded paths), and generating (design in 3D, generate code back).

There's also a Claude Code plugin (tesseract-skills) with slash commands: /arch-codemap maps an entire codebase, /arch-flow traces data paths, /arch-detail drills into subsystems.

Works with Claude Code, Cursor, Copilot, Windsurf — any MCP client. Free to use. Sign up to unlock all features for 3 months.

It's early but stable. I've been dogfooding it on real projects for weeks and it's ready for other people to try.

Happy to discuss the MCP integration, the design choices, or anything else. Would love feedback.
