Planning

Your codebase never ships uncovered

A local-first AI testing CLI that watches your code and automatically generates, updates, and maintains test suites as you develop.

Key Features

  • Watches file changes and auto-generates tests
  • Updates existing tests when code changes
  • Supports Jest, Vitest, Pytest, and Go testing
  • Local-first — runs on your machine, not a cloud service
  • Coverage gap detection and intelligent test prioritization

Built For

Solo developers and small teams shipping fast with AI coding tools

Vision

AI coding tools have made developers 5-10x faster at writing code, but the test-to-code ratio is collapsing. Specwatch bridges this quality gap by automatically generating and maintaining tests as you code — like having a testing engineer watching over your shoulder.

The Problem

Developers ship features faster than ever with AI tools, but test coverage is dropping because writing tests is still manual and tedious. Existing testing tools are enterprise-priced ($50-500+/mo) and require complex setup. No lightweight, local-first solution exists for solo developers.

Key Differentiators

  • Watch mode: Detects code changes and generates/updates tests in real-time, not as a batch process
  • Maintenance, not just generation: When you refactor code, Specwatch updates the corresponding tests automatically
  • $0-20/month: Built for indie developers and small teams, not enterprise budgets
