Fly.io runs your app as microVMs across the globe, with you at the controls. redu is a real cloud your AI agent operates end to end, on a machine it can SSH into and fix.
Fly.io wins on global distribution and low-level control. redu wins when you want your agent to operate the cloud and managed databases wired for you.
The core difference is a lower-level global microVM platform versus a full cloud your agent operates and can SSH into.
Fly.io is powerful and infra-capable. For a team that wants edge placement across many regions and fine-grained control, it is a genuinely strong platform.
Fly.io is built to run your app close to users in many regions at once. If low latency worldwide and edge placement are core to your product, Fly.io is a strong choice.
Fly Machines, volumes, and networking give you fine-grained control over how and where your app runs. For teams that want to tune placement, scaling, and configuration themselves, that control is valuable.
Fly.io is powerful and infra-capable, and it expects you to configure the CLI, images, and database setup. If you enjoy that level of control, the platform rewards it.
A lower-level platform is powerful until you want your agent to operate it, managed databases wired for you, and one place for the whole stack. redu gives you all three.
Both ship an MCP server. Fly.io's flyctl MCP wraps its CLI to manage Fly apps, machines, and volumes. redu's MCP goes wider: your agent provisions a VM and a managed database, deploys your app, wires DNS and TLS, and can SSH in to keep it running, all from one place.
Both give you a real machine with SSH. On redu your agent does the operating: it SSHes in, finds why something is failing, fixes it in place, and pushes the fix back to your repo.
redu provisions managed PostgreSQL and Redis alongside your app and injects the connection env automatically. Fly.io has capable managed data too, with Managed Postgres and Upstash Redis, but you provision and wire them as separate steps from your app.
redu runs on production infrastructure in a German data centre, so your data stays in European jurisdiction without extra configuration. Fly.io is a global, US-origin platform.
It comes down to whether you want a lower-level global microVM platform or a full cloud your agent operates and can SSH into.
Per-second usage billing can be hard to predict. Use the redu.cloud pricing calculator to estimate compute, managed databases, and storage in one place.
Practical answers for teams comparing Fly.io with redu.cloud in 2026.
Yes, if you want an agent-native cloud with managed databases wired for you and an app deployed and operated for you, rather than a lower-level global microVM platform. Fly.io remains a strong choice for globally distributed apps.
Fly.io runs across many global regions and includes European ones such as Amsterdam, but its model is global and US-origin, so European placement is something you configure. redu runs production infrastructure in a German data centre, so your data stays in the region by default.
Both have an MCP server. Fly.io ships an official flyctl MCP (experimental) that lets an agent manage Fly apps, machines, and volumes. redu goes further: any MCP-capable agent (Claude Code is the common example) can provision a VM and a managed database, deploy your app, and SSH into the machine to operate and fix it, all on one cloud.
Fly.io is pay-as-you-go billed per second, with shared machines from around $2/month, performance machines from roughly $32/month, volumes at $0.15/GB, and metered egress. redu uses per-resource hourly pricing, with servers from about £8.50/month and £200 in credits for new accounts. The right choice depends on your workload shape.
Yes. Fly Machines are real microVMs and you can open a shell with fly ssh console. The difference is that redu is agent-native, so your agent does the SSH work: it deploys the app, then SSHes in to operate and fix it, rather than leaving that to you.
Point your agent at a project, get a live URL on real infrastructure with a managed database, and decide using your own workload.
