I built Critic, an inbox for GitHub pull requests. Compared to the one built into GitHub, Critic is more flexible in that it allows to create any number of sections, each section being defined as an arbitrary search query. It allows to customize the inbox to fit exactly your workflow, so that you never miss a code review again!
Critic is an open source project (on GitHub, of course), also available for free at https://getcritic.dev/
It’s still in its early stages, so please be indulgent and feel free to give me any feedback.
Regarding the tech stack, Critic is built on top of the React Router, uses Prisma, is deployed on Vercel, and uses a PostgreSQL database provided by Neon.
