Their migration timeline from their blog:
1. August 2, 48 hours after public launch 400+ users
2. August 20, migrate from planetscale to turso (sqlite)
3. Oct 29, migrate from vercel to fly.io, migrate from nextjs to hono, also mentioned change to bunjs.
This is seems like they tend to (sorry I'm judging here):
1. move fast break things or
2. don't have a plan before launch day or
3. only chasing the latest tech buzz.
