about us
diyhrt.coffee is a free stock tracker for diy hrt. we watch the vendors so you don't have to sit there refreshing twelve tabs, and we ping you when the thing you need comes back. two people run it, and these are us.
hi, i'm phi! i took diyhrt over from akira, and now i'm the one keeping it running. the scrapers, the alerts, the uptime checks, the servers, and the 3am fixes when a vendor rebuilds their shop overnight — that's me.
if something's broken it's probably my fault, and i'm probably already on it.
n2x is the other owner, and a dev too. they build the site with me, help out on the discord, hand out the donator roles, and hold one of the canary keys.
that last one matters: if i ever go quiet, there's still someone who can sign it and tell you the site is fine (or that it isn't).
diyhrt started because diyhrt.market and hrtcafe both went down around the same time, and people still needed a way to find stock. so akira built one.
akira ran it all the way through v2.0 and handed it to me in october 2026. the handover canary is signed by both akira's key and mine, so you can check for yourself that it really was passed on and not taken.
it checks every listing from every shop we watch around the clock, keeps an uptime history for each of them, and sends restock alerts wherever you want them — discord, ntfy, gotify, or a webhook. around that there's the stuff people kept asking for: an E2 calculator, a parcel tracker, reviews, testing chips, a start guide if you're new, and a forum.
- no ads, no investors, no company. it's paid for out of our own pockets and by people who donate.
- a listing isn't an endorsement. we don't sell anything. vendors get chips for how far they've been verified — read /verified before you buy.
- you can check up on us. there's a signed warrant canary (either of us can sign it), a public uptime page, and a privacy page that says what we collect (almost nothing).
- no names needed, either way. you don't need yours to use any of it, and you don't need ours to trust it. if the clearnet site is blocked for you, there are tor and i2p mirrors.
questions, bugs, a vendor we should add, or one that's acting shady: use the contact form, come say hi on the discord, or post on the forum.
stay safe!
