FAQ

Can I use the Free tier in production?
Yes. The Free tier is fully production-ready for small teams and individuals. Upgrade to Pro if you need parallel execution, caching, or custom rules.
How does parallel execution speed this up?
Pro runs mypy, pyright, and pyre simultaneously across available cores instead of sequentially. Typical speedup is 2.5x to 3x on modern hardware.
Do you store my code?
No. All checking runs locally on your machine or CI runner. We only store non-identifying metadata for caching and performance optimization.
Can I cancel anytime?
Yes. No contracts, no lock-in. Cancel your Pro subscription at any time. Your Free tier account remains active.
Is there a discount for annual billing?
Yes. Pay annually and save 20%. Annual Pro is $470/year instead of $588.
