Show HN: SpecMind – AI architecture tool for vibe coding
github.comI wanted something that kept the architecture consistent without everyone having to stop and redraw diagrams all the time. That’s how SpecMind started. We’ve been using it in real projects, and it’s been much easier to keep track of how everything fits together.
When you run analyze, it creates .specmind/system.sm which includes multiple diagram types such as system view, per service architecture, sequence flows, and entity relationships.
design <feature> creates a spec showing proposed changes, and implement <feature> updates the architecture once the feature is built, keeping the spec and code aligned.
All files are text based and versioned in the repo. The goal is to make architecture a living part of the codebase rather than something updated later in Confluence or diagrams.
Next steps include code-to-spec validation, PR diff integration, and more language support.
Happy to answer any technical questions or hear how others deal with architecture drift in fast moving projects.
