I’ve been working on reverse-engineering Grindr and creating an open source client implementation for it since March.

When GrindrPlus closed, my project turned out to be its de-facto successor and immediatelly several thousands of people started following it. Now it has 70k+ downloads on Forgejo and the authorship is dedicated to public domain :)
- MIT licensed, no ads, no analytics, no trackers, no diagnostics, no statistics, no telemetry, only opt-in updates checking
- Signed releases, reproducible builds on all four platforms, full transparency
- And it’s now in Google Play (for the time being) and being reviewed for F-Droid!
Already applied for Apple developer enrollment and going to publish this to EU alt stores as well as in the TestFlight. Then a classic unsigned ipa and also going to attempt Apple AppStore just for completeness.
You need an existing Grindr account. Downloads: https://opengrind.org/download
Questions and criticism welcome.
they are making opensource-things about anything these days

gayest and proudest 💅
Something about MIT licensed Grindr client tickles me lol. Great job!
I assume Google (on Grindr’s instructions) will take it down eventually, but I guess you’re prepared for that by trying to put it on F-Droid
KDE gonna start shipping with Krindr
The recommended link to download is still https://opengrind.org/guides/download as well as Forgejo https://git.opengrind.org/open-grind/open-grind/releases
F-Droid is a backup for people who don’t want to egress to Open Grind infra (even though the promise not to log, analyze any IPs is legally binded by the Privacy Policy, but I understand them) or those who want to be sure every new release is reproducible (if they don’t trust Open Grind CI that verifies this automatically before each release).
Google Play is temporal listing that will get taken down soon, but it does add credibility.
i have actually been using this for a while now, found it on my own when i discovered grindr and grapheneos dont play nice, its been very cool so far, no complaints
Nice to hear that it works on GrapheneOS. If you do encounter any issues, please report them anywhere you want — Forgejo issues, Matrix chat, or even personally to me so I can relay them properly. I can’t test on GrapheneOS because don’t have a compatible device, but I assume many Open Grind users are running it on GrapheneOS.
Does something like this for heterosexual people exist? Like an open-source Tinder like app?
Not that I know of. Tinder is pretty hard to reverse-engineer, Meta-levels of bot automation detection (where bot automation means anything that doesn’t go through their official client in a way they intended)
How much work do you think would it be to also create a FOSS backend, maybe utilizing an existing xmpp server for federation?
Someone in the community already works on it. I personally don’t see a point in it — Grindr sucks in every way, all other apps are better experience-wise. Grindr is gay culture, mentioned in songs, memes, essentially every gay man in the world who has internet knows what Grindr is. 100 M profiles dating pool. It’s not realistic even for competitors to reach a fraction of this, let alone a federated social. And if you do know what federation, decentralization and XMPP are — why would you use a hookup app anyway instead of utilizing existing federation apps and social networks to find someone you like? ;)
awesome work.
