DirtWatts vs Biketerra for mountain bikers

Biketerra is the closest app to DirtWatts: it runs in the browser, has a free tier forever, and lets you ride almost any route you upload. It is built around roads and open routes. DirtWatts goes deep instead of wide: fewer trails, each rebuilt from lidar with its surface and a physics model fitted on dirt.

DirtWatts and Biketerra: questions

Can I ride mountain bike trails on Biketerra?

Biketerra builds 3D routes from map data and will draw any route you upload, but it doesn't advertise trail surfaces or an MTB physics model. DirtWatts is built only for mountain bike trails: lidar terrain, surfaces that change resistance, and a rider model fitted on dirt.

Both run in the browser. What is different?

Both use Web Bluetooth in Chrome or Edge, so neither needs an install on a computer. Biketerra covers a huge range of routes. DirtWatts rebuilds a smaller library of real trails by hand, from lidar.
