bencered/deploy-failures

This is a small Next.js web app that connects to Vercel and shows you every deployment that has failed on your account. Vercel is a hosting service where many people put their websites, and a deployment is what happens when you push new code and Vercel tries to publish it. Sometimes those deployments break, and this tool gathers all those broken ones in one place and draws charts of how often they happen. To use it, you first have to create a thing inside Vercel called an integration. The README walks through that step by step: you go to the Vercel dashboard, click Create, give it a name and a logo and a privacy policy link, and set a redirect URL pointing back at the app. You pick read-only access to deployments, projects, teams, and your user info, and Vercel hands you back a slug, a client ID, and a secret. Those go into a local environment file the app reads on startup. Once that one-time setup is done, you copy the example env file, fill in the values, run npm install, and start the dev server. You open the page in your browser, click Continue with Vercel, and install the integration on your account or your team. The app then pulls in your failed deployments and shows them as graphs styled to look like the Vercel dashboard itself. The README also lists the main files: a custom auth setup using a signed cookie instead of a library like NextAuth, two route handlers that begin and complete the OAuth handshake, a helper that pages through the Vercel API for failed deployments, and a dashboard component that renders the charts and a Worst Days table. Deploying it is just a normal Vercel deploy with the four secrets added as project settings.
