Bolt.new Models

Bolt (Claude 3.5 Sonnet + WebContainers)

Type: Code

Description: Initial Bolt launch model. Anthropic Claude 3.5 Sonnet as the code generation engine, running inside StackBlitz WebContainers browser runtime. Claude 3.5 Sonnet was the first model capable of reliable full-stack code generation — earlier models (GPT-4 Turbo, Claude 3 Opus) failed to produce working multi-file applications consistently. WebContainers ran the generated code instantly in the browser with no server startup time. Generated React, Vite, and vanilla JavaScript applications.

Architecture: Other

Bolt (Claude 3.5 Sonnet + Supabase + Multi-Framework)

Type: Code

Description: Second major version adding Supabase integration (database, auth, storage), Netlify one-click deployment, multi-framework support (Next.js, Astro, SvelteKit alongside React/Vite), and improved error recovery. Token-based pricing model introduced. Bolt could now generate complete SaaS prototypes with backend persistence — not just frontend UIs. Most-used Bolt version during the $4M to $40M ARR sprint.

Architecture: Other

Bolt (Multi-Model — Claude, GPT-4o, Gemini)

Type: Code

Description: Multi-model version allowing users to select between Anthropic Claude 3.7 Sonnet, OpenAI GPT-4o, and Google Gemini 2.5 Pro as the underlying code generation engine per session. Different models have different strengths — Claude for complex logic, GPT-4o for speed, Gemini for long-context large codebase understanding. GitHub sync, team plans, and enterprise SSO added in this version cycle.

Funding Update

$105M

Jan 2025

Raised $105M Series B at $700M valuation — announced January 23, 2025. Co-led by Emergence Capital and GV (Google Ventures). Joe Floyd of Emergence Capital joined the board. Conviction (Sarah Guo, also a board member at HeyGen) and Mantis (Justin Timberlake and Scooter Braun's venture fund) participated as new investors alongside Madrona. Company had gone from $0.7M ARR to $40M+ ARR in 5 months (Oct 2024 to Mar 2025) — one of the fastest ARR ramps in startup history. Total funding: $135M. Simons stated the company was forecasting $100M ARR by end of 2025. 1 million+ websites deployed through Netlify integration by March 2025 (Netlify confirmed). Forbes AI 50 and Wing VC Enterprise Tech 30 recognitions accompanied the round.

Funding Update

$22M

Nov 2022

Raised $22M Series A led by Insight Partners in November 2022. This was the round that funded the enterprise features build-out in 2023. By late 2023, enterprise customers had evaporated and the company stalled at $0.7M ARR. In December 2023, the Insight Partners board gave co-founders Eric Simons and Albert Pai an ultimatum: prove meaningful traction in 2024 or shut down. Simons described being close to selling the company or winding it down. The team laid off 7–8 employees, retaining a 15-person core team to attempt one final product bet: Bolt.new. Total seed + Series A: $29.9M.

Funding Update

$7.9M

Apr 2022

StackBlitz raised $7.9M seed round in April 2022. Investors not publicly disclosed. The round was raised to fund the enterprise pivot — building SSO, SCIM, team management, and admin features for large engineering teams at companies like Google and Netflix. In retrospect, the enterprise timing proved premature: the 2021 buying mania had reversed by the time features shipped, leaving StackBlitz with $0.7M ARR and near-zero enterprise demand by late 2023 despite the strong technology foundation.

More About Bolt.new

Zero to $40M ARR. One browser tab. No install required.

The speed at which Bolt.new scaled is the kind of thing that gets written into startup textbooks. Launched in September 2024 as a new product by StackBlitz — the browser-based IDE company that spent seven years perfecting WebContainers technology — Bolt.new hit $20M in annualized revenue within its first two months. By March 2025, it was at $40M ARR with just 35 people on the team. Anthropic uses it to test new models. Stripe, Google, and Meta teams build with it. The waitlist for the enterprise tier grew faster than the team could process it.

None of this happened by accident. Bolt.new landed at the precise intersection of two compounding forces: Claude 3.5 Sonnet's breakthrough zero-shot code generation ability (launched June 2024) and StackBlitz's WebContainers runtime — a full Node.js operating system that runs natively in the browser without any server infrastructure. The result is a product where you describe an app in plain English and, minutes later, it's live on the internet. No terminal. No Git. No deployment pipeline. No laptop configuration. Just a browser and an idea.

Why Bolt.new Is Different From Every Other AI Code Tool

Cursor, Copilot, and Windsurf are all built for developers — people who already know how to code and want to go faster. Bolt.new was built for everyone else. The product's defining characteristic is that it requires no pre-existing technical knowledge to produce something real:

  • WebContainers Runtime — StackBlitz's proprietary technology runs a full Node.js environment in WebAssembly directly inside the browser tab. There is no remote server, no container to spin up, no SSH session. The dev environment starts in under a second and costs a fraction of cloud-container competitors like Lovable or Replit
  • Prompt-to-Deployed App — describe what you want to build, watch Bolt write every file, install every package, run every server, and hand you a live preview URL — all without leaving the browser
  • Full-Stack by Default — Bolt generates not just the frontend but the backend, database schema, API routes, authentication flows, and deployment configuration simultaneously; the output is a complete, runnable application, not a UI mockup
  • One-Click Integrations — native connectors for Netlify (deployment), Supabase (database and auth), Stripe (payments), Expo (mobile), and Figma (design-to-code) mean you can go from idea to production-grade product without stitching together separate tools
  • Open Source Core — Bolt.new's editor is fully open source; thousands of developers have contributed improvements, forks, and custom model integrations since launch, creating a flywheel of capability improvements that no closed-source competitor can match
  • Token Rollover — unused tokens on paid plans roll over for an additional month, so heavy months don't penalize lighter ones
  • Teams Workspace — real-time collaborative editing, role-based permissions, admin controls, private NPM registry support, and design system knowledge make Bolt viable for product teams, not just solo builders

The WebContainers Moat

StackBlitz spent four years building WebContainers before Bolt.new launched. This infrastructure is the deepest competitive advantage in the product — not the AI layer, which any well-funded competitor can replicate by calling Anthropic's API. Running a full Node.js environment in the browser means Bolt.new's development environments load instantly, require zero cloud infrastructure, and cost dramatically less per session than server-side alternatives. It also means the entire editing and execution loop is private by default — your code never leaves your browser unless you choose to deploy it.

Who Builds on Bolt.new

  • Non-technical founders using it to build and validate MVPs without a CTO
  • Product managers shipping internal tools in an afternoon instead of filing a JIRA ticket
  • Designers prototyping interactive concepts that feel real, not mocked-up
  • Developers using it for rapid scaffolding before moving to a local environment
  • Enterprises like Stripe, Google, and Meta for team-level prototyping and tooling

Backing and Momentum

  • $135M total raised across seed, Series A ($22M, November 2024), and Series B ($105.5M, January 2025)
  • Series B led by Emergence Capital and GV at $700M valuation
  • Participating investors: Madrona Venture Group, Conviction, Mantis, Greylock, Tribe Capital, Flex Capital
  • Anthropic uses Bolt.new to test new model releases — a rare form of live production validation
  • $40M ARR as of March 2025, growing faster than virtually any developer tool in history

Bolt.new FAQ's

What is Bolt.new and how does it work?

Bolt.new is a browser-based AI coding agent that turns natural language descriptions into full-stack web applications running live in your browser — in under 60 seconds. Powered by Anthropic's Claude and StackBlitz's WebContainers technology, Bolt generates complete React, Next.js, Vite, and Astro applications with routing, authentication, backend logic, and database integrations without spinning up any remote servers. You describe what you want, watch the code appear, click to preview, and deploy to Netlify in one click. Unlike Cursor or GitHub Copilot, which assist developers in their existing IDE, Bolt targets non-developers: product managers, designers, founders, and anyone with an idea and no coding background.

What is WebContainers and why does it matter for Bolt?

WebContainers is a StackBlitz invention — a technology that runs a complete Node.js development environment entirely inside a web browser using WebAssembly, Service Workers, and the browser's native file system API. No remote VMs, no cloud containers, no server spin-up time. Code runs on the user's own CPU, inside their browser tab, starting in milliseconds. This gives Bolt a structural cost advantage over competitors like Lovable (which uses Fly.io cloud containers) — Bolt's infrastructure cost per generation is a fraction of cloud-based alternatives. StackBlitz spent seven years building WebContainers before Bolt was possible.

Who uses Bolt and what are they building?

Bolt's primary audience is non-developers — particularly product managers, designers, and non-technical founders. Within weeks of launch, Eric Simons discovered that paying customers were overwhelmingly PMs and business teams rather than the developers he had expected. Common use cases: internal tools, dashboards, customer-facing portals, SaaS MVPs, e-commerce storefronts, data visualization apps, and personal side projects. In March 2025, Netlify reported that over 1 million websites had been deployed by Bolt users. By March 2026, Bolt had over 7 million registered users adding more than 1 million new users per month.

What happened to StackBlitz before Bolt launched?

StackBlitz was founded in 2017 as an online browser-based IDE. Despite attracting 3 million monthly developers and enterprise users at Google, Cloudflare, and Uber, it struggled to monetize — generating less than $1 million in ARR by late 2023. After raising $22 million from Insight Partners in 2022 for enterprise features, those customers evaporated as the 2021 buying mania reversed. By late 2023, the company was weeks from shutting down. At a December 2023 board meeting, investors gave co-founders Eric Simons and Albert Pai an ultimatum: prove traction in 2024 or shut down. They laid off 7–8 people, left 15 on the team, and gave themselves 90 days to ship Bolt. The rest is among the most remarkable product pivots in startup history.

How does Bolt's pricing and business model work?

Bolt charges per token consumed — each message, code generation, and revision in the editor burns tokens from your plan. Free tier: limited tokens monthly. Pro plan: $20/month for 10 million tokens. Teams plan: $30–50/user/month with shared token pools. Enterprise: custom. Unlike Cursor's flat-rate subscription, Bolt's token model reflects its heavy reliance on Claude API costs. StackBlitz CEO Eric Simons described this as 'selling inference' — a model he said they pioneered among AI coding tools. The WebContainers cost structure (zero cloud container costs) means Bolt's gross margin is significantly higher than cloud-container competitors despite similar pricing.
