Love seeing a Treeline ride out in the wild! Weโ€™ve been thinking about how activities could travel as Web Tiles. What would you want out of an activity for something like this?

Don't worry that lots of activities have been removed from treeline (all test data, over 1000 activites). We have been doing some testing of privacy/blocking/deactivate/takedowns and account deletion. Not fancy, but needed for user safety and privacy.

@treeline.worldOct 8, 2026, 1:39 PM

Were cooking!

With over 1000 activities indexed, we needed a better way to look at the archive.

Also, skiing should be detectable and viewable as well.

The next update is in testing! Maybe out today, but @larakin.systems has to go to Moab UT. to generate more test data. So more likely next week.

oh look, a new bug. Over 1M vertical ft climbed breaks the share image. Thats a cool bug to have.

@treeline.worldOct 7, 2026, 2:53 PM

The last few weeks have been amazing at Treeline.

From our very first non-test users, to 8 others joining and 100's of activities shared!

@larakin.systems is doing his best to keep the things running.

We've got plenty more fixes in the pipeline!

Treeline v0.17.1 is out. Gear is a real thing now: add your bikes and shoes, apply them to past activities (with undo), and watch the mileage and replace-me warnings add up. Installs as an app on your phone too, and the Back button finally works.

We released this yesterday, but it was a minor change so we didn't make a post. But, a bigger .17 update is coming right around the corner.

Treeline v0.16: a feed that keeps up ๐ŸŒฒ

Activities now load in pages with infinite scroll, and you can filter by athlete, group, sport and date. Also: one-way trail passes read Climb/Descent, and group replays share the real clock.

Treeline v0.15: "Save as my activity" ๐ŸŒฒ

Forget to record? Save a copy of the track to your own account. It's co-athletes only by default, heart rate and power are stripped, it can't be more visible than the original. Hosts choose who can save theirs, and can unlink a copy.

treeline.worldEnchantments Thru HikeStarted way too early, ended way too late. That was a really challenging hike but I'm glad that we did it. Would highly recommend doing some proper training because I feel like I won't be able to walk for the next few days.

Everything is back up and running smoothly. Importing a whole 20 year history is a decent hit on the system. But it works now.

@treeline.worldSep 26, 2026, 8:07 PM

After 5 patches were back up. Still some processing to do, but things should be better.

TTreeline World@treeline.worldSep 26, 2026, 7:46 PM

Sorry guys. our appview is currently down. Some pesky test user decided to import 1200+ activities twice! (it was me, I'm the problem) Were working on the fixes. Please stand by...

Some of them are already fixed and deployed. Like better trail and segment detection. We will continually be updating and improving the appview and UI. So expect changes. Next up, Group runs and a hardened Strava bulk import. Were testing that now so you may see many new activities come and go.

@treeline.worldSep 26, 2026, 3:27 PM

Weve had an influx of users in the last 12 hours!

@pyxorium.com officially became the first non @larakin.systems account to share an acitivity.

That activity share increased traffic to our appview exponentially.

That uncovered lots of backed and fronted issues.
