CodeVitals

Open Source

Codebase governance CLI and machine-readable skill for AI coding agents. Measures source weight and shipped JS bundle size, classifies the project into a lifecycle tier, and gets stricter automatically as it scales — so AI-assisted dependency drift gets caught while it is still cheap to fix. Zero runtime dependencies.

  • Deterministic JSON contract agents like Claude Code, Cursor and Copilot read instead of guessing at code health
  • Translates bundle weight into Core Web Vitals and business cost for non-engineers
  • TypeScript
  • Node.js
  • CLI
  • AI Agent Skill
  • Core Web Vitals

InvoHQ

Product

Free invoice generator that gets the tax law right per country. Pick a country and it applies the correct tax preset, label, currency, locale and legally required invoice wording — VAT, GST/HST or sales tax — then builds a downloadable PDF beside the form. No signup, and in the anonymous flow nothing typed ever leaves the browser.

  • Country registry drives tax presets, generated country pages and defaults from one source, so a rate change is one edit
  • Tax rates stored in basis points and each carries a verified date plus the authority that sets it
  • Generator runs with no backend at all — accounts and billing sit behind a single build-time flag
  • Next.js 16
  • React 19
  • TypeScript
  • Tailwind v4
  • Supabase
  • Stripe
