Tautulli's built-in newsletter feature is the closest thing to what I wanted — a digest email telling people what's new on the media server — but it only speaks to Plex, and the layout is basically fixed. I use more than just Plex, and I wanted actual control over how the email looks, so LatestArr is the standalone version: it connects to Plex/Tautulli, plus book, audiobook, and game libraries, and sends a fully custom-branded HTML digest on whatever schedule you set. The template is built with drag-and-drop blocks, not code.
Why this project
The self-hosted homelab community has given me a lot — years of learning by building, breaking, and fixing things that only I depend on. LatestArr is me giving something back to that ecosystem directly: a real tool, not a toy, built the way I'd want to find one if someone else had written it first. It's also the project where I leaned hardest into building for a security- and accessibility-conscious audience from day one — OIDC/SSO, encrypted-at-rest credentials, rate limiting, and CSRF protection aren't an afterthought, and the admin UI is tested keyboard-only, not just with automated checks.
How it's built
I'm developing LatestArr with Claude Code as an active collaborator — pairing on architecture, implementation, testing, and code review the way I would with a very fast, very thorough teammate. Every line still gets read and understood, not just accepted; it's a genuinely different way of building software than I've worked before, and part of what I'm learning from this project is how to do that well.
Contribute
LatestArr is open source (GPLv3) on GitHub, and new source integrations are designed to be self-contained — if there's a media/library server you use that isn't supported yet, adding one doesn't require touching the scheduler, database, or UI. Issues, PRs, and adapter requests are welcome.
