Find why your app works locally but breaks on Vercel.
About DeployDoctor
DeployDoctor scans GitHub repositories for common Vercel deployment risks without running repository code. It checks import paths, environment configuration and framework-specific build issues, and offers build-log diagnosis and reviewable import patches tied to the scanned commit. For indie developers and small teams. One public scan per day per IP is free without signup; paid passes include private-repo scans. Built by NyttoLabs.
