What exists on Show HN
Built, still asked for1 Show HN launches do this job, and 19 more do part of it. People still ask, so the launches are missed, unknown, or not what they want. Ask what they’re missing before you build.
The idea, as matched
An app or browser extension that blocks distracting sites and apps with fine-grained schedules, session time limits and intent prompts that are hard to bypass, across desktop and phone.
Jev first matched 16 requests to this idea; a second reader kept 14 of 16.

Building this?
Read ten of the asks above first, because they say what the existing launches miss. If you ship it, post it as a Show HN so the next run of this list finds it.
Ship it like Vercel, on a server you own
This site runs on ShipTiffin. A push to GitHub deploys it, the way it would on Vercel, but the server is a Hetzner box in your own account. Postgres, sign-in, email, jobs and analytics are already on it, every project gets a hard limit, and nothing is billed by usage.
$19 a month per box, plus about $10 for the server at Hetzner. Open source, so you can also run it yourself for free.
