Bolt
Browser-based AI builder with editable code and integrated hosting.
What it is
Bolt New is StackBlitz's prompt-driven web app builder. You describe an application, it generates a project in the browser using WebContainers — so Node.js runs without local setup — and you keep editing the code as it iterates on follow-up prompts. Projects can be connected to databases and deployment services and shipped without leaving the tool. It is aimed at developers who want speed and less setup, and at non-developers who want a working starting point.
Bolt pricing
Bolt does not publish a plan ladder we could verify. Free tier available.
Prices read from the vendor's own pricing page on 2026-08-24. Vendors change plans without notice — check the source before you budget.
Key features
Prompt-driven building
Creates and edits supported application files through conversational instructions.
In-browser execution
Uses a browser-based Node.js runtime for installation, development and preview.
Connectors
Reads or acts on supported external services through built-in and custom MCP connections.
Bolt hosting
Publishes public or restricted projects with plan-specific domains and traffic limits.
Strengths and trade-offs
What works well
- Browser runtime: Builds and previews supported web applications without a local installation.
- Editable project code: Users can inspect and continue working with the generated files.
- Integrated publishing: Free and paid accounts can publish to a bolt.host address.
- External context: Connectors can provide authenticated access to supported tools and remote MCP servers.
Where it falls short
- Token-sensitive iteration: Reading, reasoning over and changing larger projects consumes more tokens.
- Conversation limit: Each conversation has a bounded amount of input and output context.
- Hosting caps: Free sites stop serving when the account-wide bandwidth or request allowance is reached.
- Generated-code responsibility: Production security, correctness and dependency review remain with the project owner.
Who it is for
Founders, designers and developers who want an editable web-app starting point and can review the generated implementation before release.
Pick it or skip it
Pick Bolt if
- Producing and testing an initial web application without local setup
- Projects that benefit from direct context from supported work tools
- Teams prepared to monitor both AI-token consumption and hosting usage
Skip it if
- You require the app-building platform itself to be open source or self-hosted
- No engineer can review generated code, dependencies, authorization and data handling
- Your traffic cannot tolerate plan limits or account-wide hosting allowances
Our verdict
Use Bolt to accelerate an editable first implementation, then apply normal engineering review and capacity planning; generated code and one-click hosting are not production-readiness guarantees.
Frequently asked questions
- Do you own the code Bolt New generates?
- Yes. Projects are real codebases that can be downloaded and continued in your own editor; the tool is a starting point, not a lock-in.
- Does Bolt New run the backend as well?
- It scaffolds full-stack projects and runs them in the browser through WebContainers, with integrations for databases and deployment, but serious production traffic still needs real infrastructure.
- Does Bolt have a free plan?
- Yes. Bolt offers a free tier with limits; paid plans unlock higher usage or team features.
- Who is Bolt best for?
- Founders, designers and developers who want an editable web-app starting point and can review the generated implementation before release.
- What are the main drawbacks of Bolt?
- The trade-offs we noted: Token-sensitive iteration: Reading, reasoning over and changing larger projects consumes more tokens.; Conversation limit: Each conversation has a bounded amount of input and output context.; Hosting caps: Free sites stop serving when the account-wide bandwidth or request allowance is reached..
- When should you not use Bolt?
- Skip Bolt if: You require the app-building platform itself to be open source or self-hosted; No engineer can review generated code, dependencies, authorization and data handling; Your traffic cannot tolerate plan limits or account-wide hosting allowances.
