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 was a paying customer for over 10 years and it just got worse and worse. I quit several years ago and haven’t looked back.
As it turns out, I love and I have always loved cycling and don’t need anyone else to see that.
I’m not saying that anyone else should behave the same way, you do you, but it was so freeing to just ride for the love of riding. No more “600m of circles” to make it to 200k, no more kudos to every workday commute, just the open road (or trails) and the freedom it provides.
Yes, I no longer race, but I do privately keep a record of my efforts and rides, but they’re now a side effect of the thing I love - not part of the focus.
