Run mypy, pyright, and pyre in one command
Unified CLI for Python type checking that consolidates mypy, pyright, and pyre outputs
Every artifact below transfers to your accounts on day one. The whole engine.
Custom scope to take Python Type Checker Unified from MVP shell to operating business.
The addressable market is real: 500k Python developers actively use type checking, and 20% show willingness to pay for consolidated tooling. The paid tier delivers genuine value for teams managing monorepos, enforcing consistency across checkers, and reporting centrally. Open-source core drives initial adoption. HN and r/Python communities have proven channels for Python tools. Team features and configuration unification genuinely differentiate from free alternatives.
Shell scripts and Makefiles provide identical core functionality at zero cost, and DIY remains the default for most Python developers. Pre-commit framework already handles multi-checker chaining natively and free. Most individual developers rely on IDE extensions for real-time checking, rendering CLI tools less relevant. Pyre adoption is minimal outside Meta, signaling the tool addresses a niche workflow. The TAM concentrates among solo developers with high price sensitivity.
An experienced Python developer or CLI tool creator with existing distribution in Python communities. Ideally someone with prior open-source success, active in HN or subreddit communities, or embedded in the Python ecosystem. Needs comfort with SaaS GTM, ability to drive adoption through community channels, and willingness to iterate quickly on the free-to-paid conversion funnel based on early user feedback.
