There are certainly a lot of powerful route building tools out there.
Ambulate supports importing tracks/routes GPX files, such that route planning could be done in e.g. Gaia or CalTopo and then exported as GPX and finally imported to Ambulate.
On a similar note all routes in Ambulate can be exported as GPX, so they can be imported to other tools e.g. navigation apps or GPS devices.
AFAIK neither Gaia or CalTopo have public APIs, but they both seem to support sharing in some form, perhaps it is possible for other applications, like Ambulate, to access routes directly saving the the GPX export/import steps? I'll add this as a issue for further investigation, thanks!
