Show HN: Open-source GitHub to Slack notifications

I built Radar because GitHub's notifications are noisy and hard to keep up with.

Radar lets you customize notification preferences – so you get a message when you're @mentioned, assigned, etc. It uses AI to match keywords semantically (so "auth" catches "authentication", "login", "OAuth").

It also sends daily digests: PRs waiting for your review, PRs ready to merge, your open PRs – grouped and summarized.

Stack: NestJS, Next.js, Trigger.dev for background jobs, Prisma, Slack API.

Self-hostable with PAYMENT_DISABLED=true for full access. We use it daily at my company.

Would love feedback on the notification preferences – it's the trickiest part to get right.
