Fly.io waives or refunds unintended charges from accidental deployments for paid support c
Fly.io is a global public cloud providing hardware-isolated virtual machines for full-stack and AI applications. Its Sprites offer persistent environments for AI agents with checkpointing, rollback, and multi-agent orchestration, while Fly Machines boot in under a second across 30+ regions.
Read-only public captures of Fly.io’s homepage and verified pricing page. Screenshots are dated, never live embeds, and open full-screen.
Short answers to the questions buyers and builders commonly ask about Fly.io. Each answer cites the shared ledger below, where every source is listed once.

A concise view of the jobs, capabilities and integrations described in the recorded product sources.
Documented product formats, platforms and official distribution destinations. Availability can vary by region and plan.
A concise history of software releases and material product changes. Events appear only when a dated source supports what changed.
This profile is being checked for dated releases and material product changes. Nothing appears here until the exact date and event can be verified from a recorded source.
Facts, answers, structured details, milestones and primary resource links cite this shared ledger. Each external page appears once; release tags from the same GitHub project are grouped under one release history.
These tools share a workflow, capability or audience with Fly.io. They may complement it rather than replace it, and are not presented as integrations or endorsements.
