Bolt and Replit both let you describe an app, watch an AI build it in your browser and publish it. They come at it from different directions: Bolt is built around the chat-to-app loop, while Replit is a general coding platform whose Agent builds things inside a full workspace. This comparison sticks to what each vendor documents, and leaves out anything we couldn't confirm.
The short version
| Bolt | Replit | |
|---|---|---|
| What it is | Chat-to-app builder in the browser | Browser-based coding platform with an AI Agent |
| Free plan | Yes, with a monthly token cap and a daily limit | Yes, with a free mode (check what's included) |
| Plan before building | Plan Mode | Plan mode (the Starter plan page says it needs Core) |
| Starting points | A prompt, Figma, GitHub or a team template | A prompt, with the type of output chosen up front |
| Hosting and database | Bolt Cloud handles hosting and a database for you; Netlify can also be connected | Publishing tool with Autoscale, Static, Reserved VM and Scheduled types |
| Undoing mistakes | Version history | Checkpoints and rollback |
Plans and prices change often. See Bolt's site and Replit's pricing for current details.
What they have in common
- Describe, build, refine. Both are driven by chat.
- No local setup. Both run in the browser.
- Plan first, build second. Both have a planning mode, which is a cheap way to avoid wasted effort.
- Usage meters. Bolt counts tokens; Replit has plan-based usage. Clear prompts use less of either.
- A free way to start. You can try both without paying, though serious projects tend to outgrow the free tier.
Where Bolt is stronger
- A short path to a prototype. Bolt's help centre describes a quickstart where you click Publish, wait about a minute and open the link in chat.
- Varied starting points. Bolt's homepage lists Figma and GitHub as ways to begin, alongside a plain prompt. That helps if you already have a design or a repo.
- Hosting and data without extra accounts. Bolt's docs say that Bolt Cloud handles the database automatically, rather than asking you to connect a third-party one, and you can view your tables from inside the editor.
Where Replit is stronger
- A full workspace. Replit is a coding platform, not only an app generator, so you get the room to look around, run things and keep growing a project.
- Checkpoints with database options. Replit saves checkpoints as Agent works and lets you roll back, with an option to include your development database.
- Choice of deployment type. Autoscale for apps with variable traffic, Static for sites with no backend, Reserved VM for always-on services and Scheduled for timed jobs.
Costs and limits to understand first
- Bolt's free plan is small. Bolt's own quickstart notes that following its walkthrough uses just under 300K tokens, which is the daily limit of the free plan. Plan on upgrading if you build seriously.
- Replit's free plan has limits too. The Starter plan page says its one free published app goes down after 30 days, and Plan mode needs Core.
- Publishing can cost extra on Replit. Replit documents separate publishing costs. Read them before you publish something you want to keep running.
We haven't compared exact paid prices here because they change often and we couldn't verify current figures for both.
Who should pick what
- You have a Figma design or an existing GitHub repo to start from: Bolt lists both as starting points.
- You want a place to keep building beyond one app: Replit's wider workspace is the better fit.
- You want to experiment cheaply and fast: Either. Use planning mode before you spend tokens or usage on a big build.
- You want the easiest code handover: Check each tool's current Git and export options in its docs before building something large.
To test them side by side, use the same small prompt in each. Our Replit Agent first-app recipe is a good starting point for the Replit half.
Our verdict
Bolt is the leaner pick for turning a prompt, a design or a repo into a published prototype quickly. Replit is the broader pick, with a full workspace, rollback and a choice of deployment types. Neither is universally better, so let a real test decide. For more pairings, see Lovable vs Bolt and Lovable vs Replit.
