Bolt

What it does

Writes code

YesPrompt-to-app is the core product: you describe an idea in chat and Bolt generates a working full-stack JavaScript project.Type your idea into the chat, click Build now, and Bolt transforms your idea into a working product.support.bolt.new/get-started/intro-bolt ↗

Debugs and fixes

YesThe agent troubleshoots as it builds and can apply fixes, though for runtime bugs the docs tell you to paste browser console logs back in.Bolt uses an AI agent to plan your project, write code, and troubleshoot as you build.support.bolt.new/building/using-bolt/ag… ↗

Reviews code

PartlyIt audits an entire project for security defects and fixes most of them, but it does not review a diff or a pull request another person wrote.Project security audit: Reviews your whole project, including your code and database, fixes what it can, and flags anything you need to handle.support.bolt.new/building/security ↗

Whole-codebase work

PartlyIt works across a whole imported repository and claims far larger context, yet the docs still advise splitting files over 700 lines and clearing context between tasks.Bolt handles projects 1,000 times larger than before. Its improved built-in context management can handle complexity and keep your projects running…bolt.new ↗

Ships it

YesBolt deploys the finished project itself to a live bolt.host address, with custom domains and Netlify as alternatives on paid plans.Bolt offers built-in hosting, so you can publish your Bolt project for free at a web address ending in bolt.host.support.bolt.new/cloud/hosting/publish ↗

Done-for-you service

NoThis is self-serve software you operate yourself; Enterprise adds onboarding, workshops and a success manager but no team that builds the product for you.No. Bolt is a browser-based tool. Sign up at bolt.new and start building right away. No setup or installation is requiredsupport.bolt.new/concepts/faq ↗

How much it does unattended

Runs autonomously

PartlyOne prompt produces a whole build unattended and up to twenty prompts can be queued, but every run still starts from a human message in chat.Send prompts while Bolt is working, and Bolt adds them to a queue and works through them in order. You can queue up to 20 promptssupport.bolt.new/release-notes ↗

Multi-agent

NoStandard and Max are alternatives you select per project, not collaborators; nothing documents several agents dividing or coordinating one task.Bolt offers two agents, Standard and Max, powered by large language models.support.bolt.new/building/using-bolt/ag… ↗

Agent permissions

PartlyPlan Mode keeps it read-only until you approve, and Code view lets you target or exclude files, but there is no per-action approval or permission policy.Bolt has a chat mode called Plan Mode where you can plan and ask questions without making changes to your code.support.bolt.new/best-practices/plan-mo… ↗

Which models it runs on

Claude

Yes

Open models

NoModel choice is not exposed to the user at all, so there is no path to run an open-weight model; the vendor names none of the models it uses.You choose the agent that matches your work, and Bolt handles model selection behind the scenes.support.bolt.new/building/using-bolt/ag… ↗

Model choice

NoThe vendor picks the model per task; your only lever is Standard versus Max, and Max itself requires a paid plan.You choose the agent that matches your work, and Bolt handles model selection behind the scenes.support.bolt.new/building/using-bolt/ag… ↗

Where you use it

In your editor

PartlyBolt ships its own in-browser editor in Code view, but there is no extension for VS Code, JetBrains or any external editor.Code view allows you to view the raw code behind your project. It lets you open files, make changes, and understand how everything fits together…support.bolt.new/building/using-bolt/co… ↗

On the command line

NoThere is no installable command-line tool driving the agent; the only terminal is the one inside Code view for running npm commands in the sandbox.Bolt doesn't currently have a public API, CLI, or SDK to control it programmatically from outside the product.support.bolt.new/concepts/faq ↗

In your pipeline

PartlyThrough the GitHub MCP connector it can open issues and pull requests from chat, but it cannot run as a step in a CI pipeline or review a PR automatically.Connect to GitHub to let Bolt read or create issues and pull requestssupport.bolt.new/building/using-bolt/co… ↗

In a browser

YesThe hosted web app is the only surface: everything runs in the browser through WebContainers with nothing installed locally.No. Bolt is a browser-based tool. Sign up at bolt.new and start building right away. No setup or installation is requiredsupport.bolt.new/concepts/faq ↗

Whose machine it runs on

Self-hosted

PartlySelf-hosting exists only as an Enterprise BYOK deployment into your own AWS or Azure tenant; Free, Pro and Teams are hosted by Bolt only.Yes. BYOK deployment lets you run Bolt inside your own AWS or Azure tenant with full infrastructure isolation and no shared computebolt.new/platform/security ↗

Open source

PartlyThe Bolt product itself is closed and hosted; only the Bolt Slides skill and component library has been published as open source.the Bolt Slides skill and component library is now open source at github.com/stackblitz/bolt-slidessupport.bolt.new/release-notes ↗

What it costs to run

How it meters

YesBilling is metered in AI tokens against a monthly allowance, with Teams charging per member on top; project size drives consumption per message.Bolt consumes tokens when it reads, thinks about, and builds your project.support.bolt.new/account-and-subscripti… ↗

Free tier

YesA standing free plan builds and publishes real projects without a card or a sales call, capped at 300K tokens a day.The Free plan lets you build and publish projects at no cost, with a few limits. The Free plan is best for small personal projects and experimenting…support.bolt.new/concepts/faq ↗

API access

NoThe vendor states plainly that nothing exists to drive Bolt from your own stack, on any tier including Enterprise.Bolt doesn't currently have a public API, CLI, or SDK to control it programmatically from outside the product.support.bolt.new/concepts/faq ↗

MCP server

PartlyMCP runs one way only: Bolt is a client that connects out to Notion, Linear, GitHub or custom servers, and exposes no MCP server another agent could call.When you connect an MCP server, Bolt can directly interact with your applications and data while chatting.support.bolt.new/building/using-bolt/co… ↗

Bring your own key

PartlyBring-your-own-cloud is an Enterprise deployment option; no tier lets you supply your own model API keys or inference provider.Deploy into your own AWS or Azure tenant with full infrastructure isolation and no shared computebolt.new/enterprise ↗

Buying it for a team

A company can buy it

YesTeams and Enterprise are bought by an organisation with centralised billing, business billing details and invoices through the team account.Bolt supports adding business billing details on Teams and Enterprise plans.support.bolt.new/account-and-subscripti… ↗

Seat model

YesTeams is priced per member with each paid seat carrying its own token allotment; unpaid members can view but not prompt, and no seat minimum is published.The subscription cost for Teams is per team member. Each paid team member receives a monthly token allotment based on the subscription tier.bolt.new/pricing ↗

Pooled budget

NoEvery paid seat gets a separate monthly token allotment, so a heavy user cannot draw on a colleague's unused balance.Tokens are not shared among team members.bolt.new/pricing ↗

Admin controls

PartlyAdmins can force a deploy provider, lock site visibility, block GitHub, Stripe or Supabase and bar personal workspaces, but only from the Teams plan upward.Team settings let team admins control how the team's shared workspace operates. These settings cover member roles, publishing, integrations, and data…support.bolt.new/settings/team-settings ↗

Audit log

PartlyAudit logs appear only in the Enterprise column; Teams admins get usage and member CSV exports rather than a record of administrative actions.Advanced security (SSO, audit logs, compliance support)bolt.new/pricing ↗

Single sign-on

PartlySAML and Okta or Azure AD sign-in are Enterprise-only; the Google integration documented elsewhere authenticates end users of the apps you build, not Bolt itself.SSO with Okta, Azure AD, and all major SAML providersbolt.new/enterprise ↗

What happens to your code

Opt out of training

PartlyExclusion from training is contractual and reserved for Team and Enterprise customers under an MSA or DPA; no self-serve toggle is documented for Free or Pro.Enterprise and Team customers under an MSA or DPA are excluded from model training and data sharing.bolt.new/platform/security ↗

Data residency

PartlyProcessing is US-centred with no published choice of region; only the Enterprise BYOK deployment puts the data in a tenant you control.Bolt is headquartered in the United States, and personal information may be transferred to, processed, and stored in countries outside of your…stackblitz.com/privacy-policy ↗

Getting out

PartlyCode leaves cleanly as a zip or through GitHub sync, but unused tokens expire two months after issue and are lost entirely if you stop paying.You can download your project as a zip file to work on it outside of Bolt, using your own code editor.support.bolt.new/building/using-bolt/pr… ↗

Certifications

YesSOC 2 Type 2 is certified rather than in progress, with GDPR and CCPA compliance claimed and reports released through the trust profile.Bolt is SOC 2 Type 2 certified and compliant with GDPR and CCPA. Full audit details and policies are available on our trust profile.bolt.new/platform/security ↗
