Replit vs Bolt.new compares two AI app builders that turn prompts into working software. Replit puts a full editor, a terminal, an AI agent and hosting in one browser tab. By contrast, Bolt.new writes front-end and back-end code and runs it in your browser, then deploys to Bolt Cloud or Netlify.
Our reviews score Replit 2.9 and Bolt.new 3.0. So the choice depends on what you build and how much you care about data terms.
Replit vs Bolt.new: The Short Answer
Choose Bolt.new, first, on our scores: it scores 3.0 against 2.9 and fits full-stack web apps.
Choose Replit, however, if you want apps built with a real editor; its entry paid plan is Core $20 with $20 of credits.
Head to Head
| Criterion | Replit | Bolt.new |
|---|---|---|
| Builds | Apps built with a real editor | Full-stack web apps |
| Runs and hosts | Replit’s cloud; hosting and databases | Your browser; Bolt Cloud or Netlify |
| Free plan | Daily Agent credits; one app | 1M tokens a month |
| Entry paid plan | Core $20 with $20 of credits | Pro $25 for 10M tokens |
| Billing | Effort-based; failed attempts cost too | Tokens; more per change as apps grow |
| Training on your data | Allowed by policy; no opt-in | No opt-out documented |
| Our score | 2.9 | 3.0 |
What Each Builds
To begin with, Replit puts a full editor, a terminal, an AI agent and hosting in one browser tab. As a result, it suits people who want apps built with a real editor.
In contrast, Bolt.new writes front-end and back-end code and runs it in your browser, then deploys to Bolt Cloud or Netlify. It suits people who want full-stack web apps.
Prices and Billing
Replit starts free with daily Agent credits and one published app, and its entry paid plan is Core $20 with $20 of credits. Bolt.new, meanwhile, starts free with 1M tokens a month, with Pro $25 for 10M tokens as its entry paid plan.
Billing also works differently. Replit bills by effort-based credits, and failed attempts cost too.
Bolt.new, however, bills by tokens, and each change costs more as an app grows. Our list of the best AI app builders compares all four builders.
Data and Training
On training, for Replit, its policy allows training on your code without an opt-in. For Bolt.new, by contrast, its policy documents no training opt-out.
Therefore, keep client code and regulated data out of lower plans until terms are clear. Our guide to which AI tools train on your data compares more tools.
Security
In July 2025, Replit’s Agent deleted a user’s production database, and Replit added safeguards. Generated apps, therefore, need checks on sign-in, data access and backups.
Our guide to reviewing AI-generated code also covers the checklist, and our list of the best AI for coding ranks agents for larger projects.
Winners by Category
In short, Replit wins for apps built with a real editor. The other builder, by contrast, wins for full-stack web apps.
Overall, in Replit vs Bolt.new our scores favor Bolt.new, 3.0 against 2.9.
