The free cloud coding agent

Cloud coding agents are not new. What is new is the price: everyone else locks the cloud sandbox behind the top tier of an already-expensive plan, then bills you per minute or per "credit" on top. Freebuff Cloud does the same job for $0. This is the post explaining how, and where it still falls short.

What "cloud coding agent" actually means#

A cloud coding agent is not just "an LLM that edits files." It is three things stapled together: a cloud sandbox (a real machine in the cloud with your code on it), an agent that can run commands, edit files, and iterate inside that sandbox, and a live preview so you can see the result in a browser without deploying anywhere. Lovable, Replit, Cursor Cloud, Devin, and Factory all sell some version of this. So does Freebuff Cloud — minus the invoice.

The difference is not subtle. The cheapest tier of most of these tools is terminal- or IDE-only; the cloud sandbox is the upsell. By the time you actually get the thing you came for, you are on the $50, $100, or $200/mo plan, and you are still watching a credit meter.

How Freebuff Cloud works#

1. 1Connect a repo. Sign in with GitHub and pick any repository — your own, a team repo, or one synced from Lovable, Bolt, or Replit. Public or private.
2. 2A sandbox boots. Freebuff clones it, spins up a real cloud sandbox, and configures the preview automatically. No docker compose up, no .env archaeology.
3. 3Build and share. The agent works in the sandbox while you watch. Share the live preview URL with anyone — teammates, clients, the open internet.

The price comparison, with receipts#

These are the projected yearly costs at the tier that actually unlocks the cloud-agent capability on each platform — not the entry price on the marketing page, because the entry price is usually terminal-only.

The short version: the cheapest paid cloud agent on this list is $600/yr. The most expensive is $2,400/yr. Freebuff Cloud is $0. The reason that is possible is the same reason freebuff.com exists at all — text ads cover the compute, not your credit card.

Where Freebuff Cloud is at least as good#

• Any repo, not a managed project. Connect a private company repo, a fork, a monorepo. You are not forced into a scaffold.
• Live preview that is actually live. It updates as the agent works, and the URL is shareable with non-technical people.
• No credit math. There is no ACU, no token budget, no "you have 42% of your monthly agent minutes remaining." It is free, so it is free.
• Bring projects from elsewhere. Lovable, Bolt, and Replit all sync to GitHub. Point Freebuff at that same repo and keep going — no export, no rewrite.

Where the paid tools still win (be honest)#

• Devin’s scheduling for very long jobs. Multi-day tasks with managed retries are Devin’s specialty. Freebuff is better at interactive, in-the-loop work.
• Deep editor integrations. Cursor’s in-IDE experience is genuinely nice if you live in VS Code. Freebuff Cloud is a browser-first surface.
• Enterprise SSO / procurement. If you need a signed MSA and a SOC 2 report tomorrow, the paid vendors have a sales team. We are a free product.

Who this is for#

• You started a project on Lovable, Bolt, or Replit, hit the paywall, and want to keep building without rewriting.
• You have a side project or team repo and want a shareable live preview without standing up a deploy pipeline.
• You are burning paid cloud-agent credits on work that does not need a $200/mo autonomous engineer.
• You just want to try a cloud coding agent without handing over a card.
