Saturn vs Bolt.new.

Bolt.new (by StackBlitz) generates and runs full-stack apps in an in-browser sandbox. Fast first commit, strong demo loop.

Start with Saturn Visit Bolt.new

Choose Saturn if

You want the project to keep living after the first ship. Saturn's Manage stage is the same surface; you don't need to re-platform.
You want a real deploy at a real URL on day one. Saturn ships at saturnos.app subdomains; Bolt's WebContainer is private to your session until you export.
Your project will outgrow a sandbox — auth, real database, real users. Saturn provisions that. Bolt is at its best inside the sandbox.

Choose Bolt.new if

You want to prototype something throwaway in 20 minutes. The WebContainer flow is genuinely fast for sketches.
You want full visibility into a Node.js runtime in your browser, including a terminal. Bolt's sandbox is the most direct way to that.

What’s different about Saturn.

01
Bolt runs in a WebContainer sandbox; the project lives in a browser-bound Node.js runtime. Saturn runs as a real deploy at <your-thing>.saturnos.app — the same surface a real user would visit.
02
Saturn's pipeline keeps state across stages — Plan informs Build, Build informs Manage. Bolt is sandbox-then-export: the in-browser session is the truth, and you take the code out when ready.
03
Saturn's Manage stage continues to live with the project. Bolt's after-shipping story is more 'export the code, deploy it, then it's yours to run'.
04
Both ship fast first commits. Saturn's first commit lives at a public URL with backend included; Bolt's first commit lives in an in-browser sandbox.

Frequently asked.

What's a WebContainer?

Bolt runs your project inside a Node.js sandbox that lives in your browser, courtesy of StackBlitz's WebContainer technology. It's fast to start and fully visible, but it's not a real deploy — exporting and hosting elsewhere is part of the loop. Saturn skips that step by running on real infrastructure from the first commit.

Can I export a Bolt project?

Yes — that's the expected path. Bolt is good at the first 80%; you take the code to a real host (Vercel, Netlify, your own infra) for production. Saturn's mode is different — Saturn keeps running the project across the pipeline.

Is Saturn faster than Bolt for the first commit?

They're comparable. Bolt's WebContainer starts the runtime in seconds. Saturn provisions a real deploy, which is a few seconds slower up front but means there's no second 'export and deploy' step later.

Which is better for a real product?

Saturn's pipeline is built for projects that keep living — Plan, Build, Manage on the same surface. Bolt is fastest for prototypes and sandbox demos.

How do the token economics compare?

Bolt's Free is 1M tokens / mo (300K daily cap); Saturn's Free is 200K. Bolt's Pro is $25 / mo for 10M tokens; Saturn's Pro is $29 / mo for 5M. Bolt is more generous on raw tokens; Saturn includes 5 projects and the full pipeline.
