The gist of it is that Strava just killed its free API, and will now require developers to have a subscription.
At Strava, we care deeply about developers, and the health of the developer ecosystem. There are now 241,000 Strava API developers, up from 185,000 last year. Starting today, all current and future applications will automatically receive access to the Standard developer tier. This allows you to serve up to 10 athletes and start building immediately, completely eliminating the previous queue.
This essentially kills thousands of tools people build using the free API.
If you’re looking to move away from Strava, so far I’ve found two open source alternatives:


I use endurain since day one and it’s growing fast and good. Dev is very dedicated and progress is significant and solid.
Said so, I always despised Strava and never used it. But I use Garmin platform since I own many garmin devices for run bike and more … And after all these years Garmin stuff, also on software side, keeps being non enshittified
It will be even better once gadgetbridge finishes support for sending to endurain. Then we won’t even need Garmin!
You do realize gadgetbridge is entirely volunteer-driven, right?
