Looking for an alternative to Bolt.new?

When the sandbox stops being enough — when the project outgrows a WebContainer and you need a real deploy with auth, a real database, and a URL someone outside your tab can visit.

Already shipping in Bolt.new?

What it actually costs to switch.

  • If your projects are throwaway 20-minute sketches, Bolt's WebContainer is faster than Saturn's full provision. Saturn isn't faster for sandboxed demos; it's the right surface when the project keeps living.
  • Saturn doesn't import a Bolt session directly. Bolt exports cleanly — push to GitHub, then describe the project in Saturn's Plan stage and the pipeline rebuilds on real infra.
  • Bolt's Pro at $25 / mo includes 10M tokens with rollover; Saturn's ladder is Starter $19 → Pro $39 → Team $79 / seat (3-seat min) with the full Plan / Build / Manage pipeline. Hit your monthly cap on Saturn and you choose — upgrade or grab a $15 Credit Pack. Switching trades raw token volume for pipeline structure.
  • Bolt's WebContainer is genuinely good at full visibility into a Node.js runtime in your browser. If that's the work, staying makes sense — Saturn abstracts the runtime in favor of the pipeline.

Stay with 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.

Switch to 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.

Frequently asked.

What's the best alternative to Bolt.new for production apps?

Saturn. Bolt's WebContainer is at its best for prototypes and sandboxed demos; the deploy-and-host story is export-then-self-host. Saturn ships at a real URL on day one — same surface for Plan, Build, and Manage so the project keeps living.

Is there a Bolt alternative without the in-browser sandbox?

Saturn runs as real infra from the first commit at <your-thing>.saturnos.app. The codebase, the database, the deploy — all real, no WebContainer middle step.

Can I move a Bolt project to Saturn?

Bolt's export to GitHub makes the codebase portable. Saturn rebuilds from a Plan-stage description rather than ingesting the repo directly — paste your spec or describe what you've built and the pipeline takes it from there.

Why would someone leave Bolt.new?

Bolt's loop is sandbox → export → deploy → manage elsewhere. Saturn's loop is one surface across Plan / Build / Manage. The departure moment is usually the second time you're re-platforming a Bolt project to host it for real.

Is Saturn faster than Bolt for first commit?

Bolt is faster — WebContainer starts in seconds. Saturn provisions a real deploy, which is a few seconds slower. The trade is that there's no second 'export and deploy' step later in Saturn.
