# Bolt — Browser-based AI agent that builds, hosts and publishes full-stack JavaScript web and mobile apps from prompts. > Source: The Agents Index — https://theagentsindex.com/bolt-new (structured, researched, re-verified) > Facts last verified: 2026-09-11 Bolt is a browser-based AI coding agent from StackBlitz that turns written prompts into full-stack JavaScript web and mobile apps. It runs each project in a WebContainer sandbox and bundles database, authentication, hosting and domains through Bolt Cloud. | Fact | Value | | --- | --- | | Website | https://bolt.new | | Price | from $25/month billed monthly, $18/month billed annually | | Free tier | Yes | Free plan at $0: 300K tokens per day and 1M tokens per month with no rollover, Standard agent only, 10MB uploads, bolt.host hosting capped at 10GB bandwidth and 333,333 requests a month, a Made in Bolt badge and no custom domains. ## What it does **Writes code** · Yes — Prompt-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. > — https://support.bolt.new/get-started/intro-bolt · Intro to Bolt, opening paragraph **Debugs and fixes** · Yes — The 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. > — https://support.bolt.new/building/using-bolt/agents · Choose an agent, introductory paragraph **Reviews code** · Partly — It 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. > — https://support.bolt.new/building/security · Check your project's security, 'two types of security checks' list **Whole-codebase work** · Partly — It 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 smoothly. > — https://bolt.new · Homepage, 'Build big without breaking' block **Ships it** · Yes — Bolt 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. > — https://support.bolt.new/cloud/hosting/publish · Publish your project to a live website, opening paragraph **Done-for-you service** · No — This 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 required > — https://support.bolt.new/concepts/faq · FAQs, 'Do I need to download or install any software to use Bolt?' _Not established: Writes tests_ ## How much it does unattended **Runs autonomously** · Partly — One 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 prompts > — https://support.bolt.new/release-notes · Release notes, Aug 24-30, 'Queue prompts while Bolt is building' **Multi-agent** · No — Standard 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. > — https://support.bolt.new/building/using-bolt/agents · Choose an agent, introductory paragraph **Agent permissions** · Partly — Plan 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. > — https://support.bolt.new/best-practices/plan-mode · Plan before building with Plan Mode, opening paragraph ## Which models it runs on **Claude** · Yes **Open models** · No — Model 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. > — https://support.bolt.new/building/using-bolt/agents · Choose an agent, second paragraph **Model choice** · No — The 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. > — https://support.bolt.new/building/using-bolt/agents · Choose an agent, second paragraph _Not established: GPT_ ## Where you use it **In your editor** · Partly — Bolt 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 behind the scenes. > — https://support.bolt.new/building/using-bolt/code-view · Use Code view, opening paragraph **On the command line** · No — There 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. > — https://support.bolt.new/concepts/faq · FAQs, 'Does Bolt have an API?' **In your pipeline** · Partly — Through 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 requests > — https://support.bolt.new/building/using-bolt/connect-mcp · Connect to an MCP server, examples list in the opening section **In a browser** · Yes — The 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 required > — https://support.bolt.new/concepts/faq · FAQs, 'Do I need to download or install any software to use Bolt?' ## Whose machine it runs on **Self-hosted** · Partly — Self-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 compute > — https://bolt.new/platform/security · Security questions answered FAQ, 'Can I deploy Bolt in my own cloud?' **Open source** · Partly — The 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-slides > — https://support.bolt.new/release-notes · Release notes, 'Bolt Slides open-source library' ## What it costs to run **How it meters** · Yes — Billing 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. > — https://support.bolt.new/account-and-subscription/tokens · Tokens, opening section **Free tier** · Yes — A 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 with AI development. > — https://support.bolt.new/concepts/faq · FAQs, 'What's included in the Free plan?' **API access** · No — The 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. > — https://support.bolt.new/concepts/faq · FAQs, 'Does Bolt have an API?' **MCP server** · Partly — MCP 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. > — https://support.bolt.new/building/using-bolt/connect-mcp · Connect to an MCP server, opening paragraph **Bring your own key** · Partly — Bring-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 compute > — https://bolt.new/enterprise · Everything your team needs section, BYOK Deployment card ## Buying it for a team **A company can buy it** · Yes — Teams 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. > — https://support.bolt.new/account-and-subscription/corporate-commercial · Corporate and commercial, 'Manage corporate billing details' **Seat model** · Yes — Teams 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. > — https://bolt.new/pricing · Frequently asked questions, 'How do Teams plans work?' **Pooled budget** · No — Every 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. > — https://bolt.new/pricing · Frequently asked questions, 'How do Teams plans work?' **Admin controls** · Partly — Admins 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 exports. > — https://support.bolt.new/settings/team-settings · Team settings, opening paragraph **Audit log** · Partly — Audit 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) > — https://bolt.new/pricing · Pricing plan cards, Enterprise column feature list **Single sign-on** · Partly — SAML 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 providers > — https://bolt.new/enterprise · Everything your team needs section, 'Secure and Compliant' card ## What happens to your code **Opt out of training** · Partly — Exclusion 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. > — https://bolt.new/platform/security · Security questions answered FAQ, 'Does Bolt use my code or prompts to train AI models?' **Data residency** · Partly — Processing 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 jurisdiction, including the United States. > — https://stackblitz.com/privacy-policy · Privacy Policy, section 9 'International Data Transfers' **Getting out** · Partly — Code 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. > — https://support.bolt.new/building/using-bolt/projects-files · Manage your projects, 'Download a project' **Certifications** · Yes — SOC 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.
