Fly.io alternative: ComputeSphere vs Fly.io
Moving off Fly.io? ComputeSphere deploys from a git push, with unlimited team members on every plan. The difference is how compute is billed: Fly.io bills Machines by the second while they run, while each ComputeSphere service runs on spherelets at a fixed monthly price, from $6, so you know what compute costs before you deploy.
Fixed price per spherelet
Flat plan per team — unlimited members, no per-seat fees
Compute at a fixed monthly price per spherelet, not metered by use
Logs and health checks on every plan; SphereOps dashboards from Pro
SphereFiles volumes — persist across deploys
Autoscaling on the Team plan, within the spherelets you hold
Custom domains with automatic SSL
Two-step sign-in; roles and an audit log on every plan
Hobby $0 + 14-day free trial

What your Fly.io setup becomes
The pieces most Fly.io apps use have a direct match.
| On Fly.io | On ComputeSphere |
|---|---|
| Process group with an HTTP service | Web service |
| Process group without a service | Background worker |
| Scheduled Machine or Cron Manager job | Scheduled job |
| Managed Postgres | SphereDB (PostgreSQL 16, 17 or 18) |
| Upstash for Redis | SphereCache (Valkey) |
| Volume | SphereFiles volume |
| Secrets | Environment variables |
| Machine size | Spherelet size, at a fixed monthly price |
Move a service in four steps
Connect your repo
Connect the GitHub repo for your Fly.io app. ComputeSphere builds it, with or without a Dockerfile, and deploys it.
QuickstartCopy your secrets
Add your secrets and the env values from fly.toml to the service, and keep secrets as secrets.
Environment variablesMove your database
Create a SphereDB database; your services get DATABASE_URL. Load your data with pg_dump and pg_restore over csph db tunnel.
PostgreSQL on SphereDBPoint your domain
Add the domain and update its DNS record. The certificate is issued and renewed for you.
Custom domains
Why teams choose ComputeSphere
Predictable pricing and push-to-deploy, with domains, SSL, logs and health checks on every plan.
Flat, predictable pricing
A flat plan per team with unlimited members, plus a fixed price per spherelet. You know what compute costs before you deploy.
The basics on every plan
Custom domains with SSL, zero-downtime deploys, logs and health checks come with every service — not add-ons you assemble one by one.
Ship from a single push
Connect a repo or start from a template — ComputeSphere builds it and routes it with SSL. No Dockerfile required, and no servers to look after.
Security you can check
Password sign-ins ask for a second step. Environment secrets, registry credentials and git connection tokens are encrypted with a key unique to your account. Services and their databases talk over a private network, and every plan gets roles for your team and an audit log.
How we split security with youFrequently asked questions
How is ComputeSphere different from Fly.io?
Fly.io bills by the second for the resources your machines consume and leaves scaling and ops largely to you. ComputeSphere charges a fixed price per spherelet on a flat team plan, with deploys, SSL, logs and health checks managed for you, and autoscaling on the Team plan.
Is ComputeSphere more predictable than Fly.io?
Yes — Fly.io's bill moves with usage, while ComputeSphere's compute is a fixed price per spherelet, so you know what compute costs before you deploy.
Can I migrate from Fly.io to ComputeSphere?
Yes. Connect the same repo, copy your secrets, load your Postgres data into SphereDB, and point your domain. Process groups, scheduled Machines, volumes and Upstash for Redis each have a direct match, and the steps above link to the guide for each.
Does ComputeSphere have a free trial?
Yes, 14 days on every plan. A card is required to start, and from day 15 you pay for your plan (Hobby is $0) and the spherelets your account holds, unless you cancel before then. Fly.io no longer offers a free tier, only a short trial.
