Show HN: Composer – AI architect / MCP for software architecture diagrams
TL;DR
Composer is a new tool that converts natural-language ideas into software architecture diagrams automatically.
Key Points
- Via MCP integration, it can analyze an existing codebase and render it as a visual diagram.
- It connects to popular AI coding environments like Claude Code, Codex, and OpenCode through the MCP interface.
- Composer is currently free at usecomposer.com and actively seeking user feedback.
Nauti's Take
The idea is solid and the pain point is real – anyone who has spent hours maintaining Miro boards that became obsolete after the next refactoring will understand the appeal. The critical question is how well the generated diagrams stay readable on large, organically grown codebases.
Three Hacker News points and zero comments at launch is not a death sentence, but Composer needs to collect real user voices fast before the moment fades. Anyone who regularly explains architecture to stakeholders should try it now – free entry means zero risk.
