Bolt.new - AI Code Assistants Tool

Overview

Bolt.new is a browser-first AI development agent that lets you prompt, run, edit and publish full‑stack web applications without local setup. The interface combines large language model agents with StackBlitz’s WebContainers so projects can install npm packages, run Node servers, and preview live apps entirely in the browser. The open-source repo exposes the same foundation used by the hosted product, making it a practical starting point for teams building AI-driven developer tools. ([github.com](https://github.com/stackblitz/bolt.new)) Bolt targets product builders, designers, and engineers who want rapid prototyping to production flows: natural‑language scaffolding, multi‑file edits, built‑in hosting, and one‑click publish. Bolt’s hosted product lets you choose between agent types and Anthropic Claude model variants (Haiku, Sonnet, Opus, including Opus 4.6 with configurable effort), integrates Figma import, supports Bolt Databases and Supabase, and exposes GitHub import/export — enabling an end‑to‑end prompt → run → deploy workflow. For developers running the open source repo locally, the codebase requires Node >= 18.18.0 and uses pnpm as the package manager.

The Bolt.new repository is active and well starred: the public repo shows ~16.2k stars and ~14.6k forks, published under an MIT license. The repository includes ~100+ commits and a small core contributor group (shown as ~15 contributors on GitHub), indicating a maintained open‑source template rather than a large community project. The codebase is primarily TypeScript (≈90%) and includes a pnpm lockfile, Cloudflare/Remix deployment scripts, and WebContainer client dependencies — useful signals for developers evaluating local runs or forks.

Installation

Install via pnpm:

git clone https://github.com/stackblitz/bolt.new.git

cd bolt.new

pnpm install

pnpm run dev

Key Features

• Full in‑browser dev environment via WebContainers — install npm packages and run Node servers. ([github.com](https://github.com/stackblitz/bolt.new))
• AI agent controls environment: filesystem, terminal, package manager, server, and browser console. ([github.com](https://github.com/stackblitz/bolt.new))
• Model selection with Anthropic Claude variants (Haiku, Sonnet, Opus 4.5/4.6) and Plan/Discussion modes. ([support.bolt.new](https://support.bolt.new/building/using-bolt/agents?utm_source=openai))
• One‑click publish/hosting with built‑in Bolt Cloud (hosting, analytics, custom domains). ([bolt.new](https://bolt.new/pricing))
• GitHub integration: import/export repos, create branches, and automatic commits from the editor. ([support.bolt.new](https://support.bolt.new/integrations/git?utm_source=openai))
• Bolt Databases plus Supabase integration for persistent backends and auth flows. ([support.bolt.new](https://support.bolt.new/release-notes?utm_source=openai))
• Figma frame import and multi‑file edits for design‑to‑code workflows. ([support.bolt.new](https://support.bolt.new/release-notes?utm_source=openai))

Community

Bolt.new has an active open‑source presence (16k+ stars, many forks) and an official Discord for support and discussion. Users praise its speed for prototyping and the end‑to‑end prompt→deploy flow, but community threads report recurring complaints about token consumption, reliability on complex integrations, and occasional model/deployment regressions — common concerns with AI‑first dev tools. StackBlitz/Bolt publish release notes and docs (agents, token guidance, billing) and maintain a pricing/tokens model for hosted usage. If you plan production use, treat outputs as scaffolded starting points and review generated code carefully. ([github.com](https://github.com/stackblitz/bolt.new))
