:keyboard: A real Linux box in one line — no signup, no card

Your SSH key is the account — a key drawn as an ID badge hanging over dissolving signup fields: no email, no password, no card, ready in 1.4 seconds, free

You open a terminal, type one line, and a machine answers you. Not a demo. Not a sandbox toy. A real Linux box with 2 vCPU and 2 GB of memory, ready in about 1.4 seconds — and at no point in that process did anyone ask for your email, your password or your card.

Your SSH key is the account. That is the whole trick, and it is worth reading twice. There is no signup, no verification email, no payment form anywhere in the flow. The key you already have on your machine is the identity — the same key lands you back in the same box every time. No key yet? One command first, then try again.

:stopwatch: Two clocks, and the one people mix up

  • 60 minutes to build. That is your working window: use it, test it, run something on it.
  • Then 24 hours to claim it. A link in the welcome message takes you to a signup, and the box moves into your account with the same machine, the same files and the same URL.

Miss the window and it is deleted, files and all. So the honest way to say it: this is a free hour, plus a day to decide — not a free server. Which is exactly why it is worth knowing the two clocks before you start.

:toolbox: What is already installed

Seven coding agents ship in the image: the Railway Agent, Claude Code, Codex, OpenCode, Cursor CLI, Grok and pi, each with an AI budget attached. Alongside them: Node, Python, gh, mise, the Railway CLI, and Chromium with Playwright — so a browser automation job runs with no setup either.

Anyone who has spent an afternoon installing a dev environment knows what that list is worth. It is the difference between “let me try this” and “let me find the install docs first”.

:shield: The rules of the road

  • 3 boxes per IP address per day, plus a shared AI budget per IP per day.
  • The preview URL answers only your IP until you claim the box. Send the link to a friend before claiming and it will not open for them — claiming is what makes it shareable.
  • IPv4 only for now.
  • Busy? It can answer “Anonymous trials are temporarily disabled” — and that refusal does not count against your daily limit.

:performing_arts: Three things here are called “free”

The free box is the bigger machine, which surprises people:

  • Free VM — 2 vCPU, 2 GB, no account at all.
  • Free Trial — a one-time $5 grant, up to 30 days, needs an account.
  • Free plan — what the Trial falls back to: 1 vCPU and 0.5 GB, with $1 of credit a month.

So the biggest of the three is the one that asks you for nothing.

:luggage: When the hour ends — where the free compute keeps going

The box is the doorway. These are the doors behind it, and every one was checked live today.

  • Railway free VM — the box above. Nothing needed, and it ends fast.
  • LinuxOnTab — a real Linux kernel in your browser tab, no account, no terminal, no server. The best first stop for a total beginner.
  • instanode.dev — one curl gives you a real, dedicated Postgres for 24 hours, no signup and no API key.
  • Google Cloud Shell — a real VM with 5 GB of persistent disk and a 50-hour weekly quota.
  • GitHub Codespaces — 120 core hours and 15 GB a month on a free account — about 60 hours of a 2-core machine.
  • Oracle Always Free — the one that keeps existing: 1,500 OCPU hours and 9,000 GB hours per month, which Oracle itself calls 2 OCPUs and 12 GB. Every guide repeating “4 cores and 24 GB” is quoting something Oracle’s own page no longer says.
  • Google Cloud free tier — one e2-micro instance a month, with a free limit that does not expire.
  • Google Colab — free notebooks with CPUs, GPUs and TPUs inside usage limits.
  • Hugging Face Spaces — static Spaces free for everyone; a free account hosts up to two ZeroGPU Spaces with 5 GPU minutes a day.
  • AWS Free Tier — $100 on signup plus up to $100 more, good for six months — and then the account closes itself, so take the credits on purpose.

:warning: What to expect, honestly

Railway has been through a global outage, and the Hacker News threads about its abuse handling are blunt — one describes the platform’s approach as “a $5/mo fee gate”. The free box exists inside that design: per-IP caps, a shared AI budget, an IP-locked preview. Read it for what it is — the fastest possible first hour on a real server, from a company clearly learning how to run a free tier in public — and it delivers exactly that.

:bullseye: Why this one is different

Most “free server” offers make you pay with a signup: an email, a verification link, a card for identity. This one makes you pay with an hour. Type one line, get a real box, and decide afterwards how long you want to keep it.

60 minutes to build, 24 hours to claim, 3 boxes a day, no card ever. That is the whole deal — and the install list means you can spend the hour building instead of installing.

Type it and post what you built below. :backhand_index_pointing_down:
