Bolt.new is a fast browser app builder. These Bolt.new alternatives help when you need broader AI work, a different stack, or more control over the code.
The best Bolt.new alternative depends on whether you want another prompt-to-app builder or a workspace that covers the project around the app. Krater.ai is the strongest broader option: /build creates full apps, sites, scripts and components with a live preview in Studio, and the same 400+ model workspace handles research, copy, images, video, voice and documents. Lovable is a close app-building rival, Replit adds a cloud IDE and hosting, v0 is strong for interfaces, and Cursor gives developers repository-level control.

Bolt.new is StackBlitz's browser-based AI app creator. You describe a product, it generates code, and you can run and refine the result without setting up a local development environment. It is particularly appealing for founders and makers who want to see a working web interface quickly.
Pricing is tied to plans and AI usage. At the time of writing, paid access starts from around $20 per month, with allowances and limits changing over time. That figure is approximate, so check their pricing page for current figures before comparing plans.
Bolt.new's strength is speed from idea to browser preview. It is less of a complete business workspace: the research, launch copy, customer documentation and media assets around the app generally come from separate workflows.
Prompt usage adds up. A first pass may be quick, but repeated fixes, dependency changes and visual refinements consume more usage than a simple demo suggests.
The browser loop can hide complexity. When a generated app needs authentication, data rules, error handling or a deployment decision, someone still needs to understand the code and its boundaries.
The product is app-centered. A working interface is only one part of a launch. Teams also need customer research, positioning, copy, images, videos, internal documents and follow-up.
Model choice matters. Bolt.new provides a focused generation experience. Teams choosing different models for architecture, analysis, writing and media often choose 400+ models in one workspace.
The handoff may need a different shape. Some teams want a hosted IDE, while others want a generated interface that moves directly into an existing repository. Bolt.new does not cover both workflows equally.
These Bolt.new alternatives are deliberately different. Compare the work you actually need to finish, not only the first screen an AI can generate.
Krater.ai brings 400+ models into one All-in-One AI workspace. /build creates full apps, websites, scripts and components with multi-file output and a live preview in Studio. Publish to yourname.krater.site, or connect GitHub, Supabase and Vercel through Additions.
After the prototype, the same chat can run /research, /image, /video, /tts, /document and /slides. Pro is $20 per month with 1,500 credits, and /build starts at 5 credits plus model token cost. See Krater.ai pricing.
Best for: businesses and teams that need to finish the app, the launch and the customer work without opening another AI subscription.
Lovable is a close Bolt.new alternative for React and Supabase applications. Its interface is approachable and the prompt-to-preview loop is easy to understand. Paid plans start from around $25 per month at the time of writing, so check their pricing page for current figures.
Choose Lovable when its preferred stack matches the product and you value a specialised workflow. Bolt.new is more flexible for some framework experiments.
Replit adds an editor, terminal, databases, hosting and deployments around AI-assisted coding. Plans start from around $20 per month, with usage details changing, so check their pricing page for current figures.
Replit is the better move when the generated app needs to become a codebase that developers inspect and run. Bolt.new is faster when the immediate goal is a browser prototype.
v0 is strong at generating polished React and Tailwind interfaces from prompts. Individual access starts from around $20 per month at the time of writing, so check their pricing page for current figures.
v0 is a good choice when a developer will connect the interface to a larger application. Bolt.new is more oriented toward running the full browser project.
Cursor is an AI code editor for developers who want to read and change the repository directly. Plans start from around $20 per month, and you should check their pricing page for current figures.
Cursor is not a hosted prompt-to-app product. It wins when code review, refactoring and control matter more than the shortest path to a first preview.
Bolt.new and Krater.ai both make app creation conversational, but the product boundary is different. Bolt.new is a focused browser development loop. Krater.ai makes /build one command among writing, research, images, video, voice, documents and slides, with a shared credit pool.
| Feature | Bolt.new | Krater.ai |
|---|---|---|
| Core workflow | Browser prompt-to-app creation | App creation plus full business workflow |
| Code output | Generated browser project | /build creates multi-file apps, sites and scripts |
| Preview | Runs in the browser | Live preview in Studio |
| Model choice | Focused product-managed workflow | 400+ models |
| Media and documents | App-centered | /image, /video, /tts, /document and /slides |
| Connections | Browser development workflow | GitHub, Supabase and Vercel in Additions |
| Pricing | Plan and usage allowances | Pro $20/mo, 1,500 shared credits |
| Free tier | Yes, daily token allowance | No |
Start with the product problem, then use the app output as the foundation for the rest of the launch.
/research with the audience, competing products and questions that need cited answers./build with the brief and acceptance criteria. Review the multi-file result in the live Studio preview./image for visuals, /video for a product clip, and /tts for a voiceover.yourname.krater.site address, or connect GitHub, Supabase and Vercel through Additions./build to create the smallest comparable app and inspect the live preview in Studio./research and ask for a launch plan, then use /image or /video for the assets the prototype needs.Both support conversational app creation, but Krater.ai makes /build one part of an All-in-One workspace with 400+ models and commands for research, media and documents.
Yes. /build supports full apps, sites, scripts and components with multi-file output and a live preview in Studio.
Bolt.new is a strong focused browser development loop. Krater.ai is better when the developer or team also needs research, copy, images, video, voice and documents in the same context.
A /build run starts at 5 credits plus the selected model token cost. Pro is $20 per month with 1,500 credits shared across all commands.
Krater.ai has no free plan and no free trial. Pro is $20 per month with 1,500 credits, Ultra is $49 for 4,000 and Max is $119 for 10,000.
Bolt.new remains an excellent choice for a fast browser prototype and a focused app-building loop. If that is the entire job, there is no need to move. If the app must become a launch with research, copy, product visuals, demo video and supporting documents, Krater.ai puts those outputs beside /build and 400+ models.
