Looking for a Fly.io alternative?

Astris runs your web apps, workers, cron jobs, databases and storage in one pool, at one monthly price. Your coding agent deploys it all from Claude Code, Cursor or Codex.

At a glance

  • $25

    A month on Growth for a web app, a worker and a Postgres database. The same in a spike month.

  • $0

    In egress fees, on every plan.

  • 1 pool

    Shared by all your apps, databases and storage. No limit on projects.

  • No overage

    Astris never sends an overage invoice.

The database is part of the plan.

On Fly.io, compute is cheap and Managed Postgres is priced on its own. On Astris, Postgres and Redis run in the same pool as your apps, at one monthly price.

Example from the Astris Console: the pool of a Growth plan, with the memory, CPU and disk in use, and the apps and databases that share it.
Example

The same app, side by side.

One web app with 1 GB of memory, one worker with 512 MB, and a Postgres database with 1 GB of memory and 10 GB of disk. 10 GB of traffic a month.

  • A database in your pool.

    Create managed Postgres or Redis with one command. It uses your plan, not a second bill.

  • A price you know ahead.

    Your plan is a fixed pool you can see. A busy month costs the same as a quiet one.

  • Your agent does the deploy.

    Claude Code, Cursor or Codex deploy through the Astris MCP.

Is Astris right for your app?

A good fit when

  • You build with Claude Code, Cursor or Codex.
  • Your app needs a worker, a cron job or a database.
  • You want to know the bill before the month starts.
  • You run more than one project and want one bill.

Look elsewhere when

  • You need a free plan. Plans start at $10 a month, and you can cancel at any time.
  • Your app is built as functions. Astris runs apps as long running containers.

Move your app with one prompt.

The guide to moving an app gives a checklist and one prompt for your coding agent. Your agent runs the preflight check, deploys the app and attaches its database.

Read the move guide

  1. Step 1. Connect your agent.

    Sign in with GitHub, pick a plan and add the Astris MCP to Claude Code, Cursor or Codex.

    claude mcp add --transport http astris https://api.astris.run/mcp --header "Authorization: Bearer PASTE_KEY_HERE"

  2. Step 2. Give it the move prompt.

    Paste the prompt from the guide to moving an app. Its checklist shows what to check first.

    Move this app to Astris with the Astris MCP. Do the steps in order. If a step fails, stop and tell me what failed.

  3. Step 3. Get a live address.

    Your app runs on astris.live with HTTPS, with its database attached.

    https://harbor.astris.live

Before you switch

What happens when my apps need more than my plan?
Astris does not create the new app or database, and it tells you which plan has room. We email you as your memory fills up. Going over your plan is refused, not billed.
Do you charge for traffic or requests?
No. There is no charge per request. Pro, Scale and Business include unlimited traffic. On Starter and Growth, traffic is included, with no egress fees.
Do you back up my database?
Yes, for Postgres. Nightly encrypted Postgres backups, kept for 30 days, restore on request. To ask for a restore, write to support@astris.run.
Can I cancel at any time?
Yes. Your plan stays on until the end of the month you paid for.
Who answers my support requests?
A person, on every plan. Write to support@astris.run from your account email.

Still unsure? Write to support@astris.run.
