Fly.io

Fly.io deploys apps in standard containers across a global edge network, with pricing tied to actual usage rather than proprietary resource units. It has never invented a lock-in abstraction to compete with AWS Lambda or Vercel’s compute tier—migrations out are straightforward. The developer-facing culture (transparent postmortems, public roadmap, responsive forums) tracks more like a tools company than a cloud platform building a moat. $70M Series B creates future investor pressure, but current behaviour is stage 1: honest pricing, no lock-in design, dev-aligned defaults.
