The 3 best Bolt.new alternatives

Bolt (bolt.new) is StackBlitz's AI builder for websites, web apps, mobile apps and prototypes. You describe what you want, and an AI agent plans the project, writes the code and runs it in a full development environment inside your browser, built on StackBlitz's own WebContainers technology, so there is nothing to install. Bolt Cloud adds hosting on a free bolt.host address or your own domain, a built-in database with authentication, file storage and server functions, and domain purchase; Bolt says it is powered by Netlify and Supabase. You choose between two agents, Standard and Max, and Bolt picks the models behind them; mobile apps go through Expo. Projects sync to GitHub or download as a ZIP.

Bottom line

For most people coming from Bolt.new the strongest open alternative is Dyad: a free, actively released desktop app builder (Apache-2.0 core) that uses your own model keys, a ChatGPT subscription or a local model, and keeps every project as a Git repository on your disk. If you want the Bolt interface itself, bolt.diy is the official open-source edition you run yourself; read its WebContainer licence terms before using it for paid work. Google AI Studio's Build mode is the free hosted option if a Gemini-only builder suits you.

The cost

Verified on bolt.new/pricing and support.bolt.new 2026-10-06. Free is $0 with a 300K-token daily limit and 1M tokens a month, Bolt branding on published sites and hosting up to 333K web requests; a free site that passes its limit goes offline until the month resets. Pro starts at $25 a month billed monthly for 10M tokens, with no daily limit, custom domains, 1M web requests and unused tokens rolling over (valid for two months); larger Pro tiers carry more tokens. The pricing page advertises up to 28% off for yearly billing, while Bolt's billing help says 10%, so check the figure at checkout. Teams is $30 per member per month billed monthly, with tokens allotted per member rather than pooled; Enterprise is custom. Bolt says most token use comes from syncing your project's files to the AI, so larger projects cost more per message. Extra token reloads are limited to the top monthly Pro plan or an annual Pro plan, and subscriptions are non-refundable. A $9/month Lite plan, built on Bolt Forge's open-source models, is open to new sign-ups until 14 October 2026.

What Bolt.new actually costs

Why people consider an alternative

Three reasons come up most. Token cost grows with the project: Bolt's own FAQ says most usage comes from syncing your project's files to the AI, so the same small request costs more as an app grows, and the free plan stops at 300K tokens a day. Model choice: you pick an agent, Standard or Max, and Bolt chooses the model behind it; its documentation describes no way to bring your own API key or a local model, and Bolt Forge, which offers four open-source models on Bolt's infrastructure, is a research preview. And place: the builder runs in StackBlitz's hosted environment, so people who want the tool itself on their own machines, or who would rather pay a model provider directly, look for one they can run.

When Bolt.new is still the right call

If you want to build without installing anything, Bolt is hard to beat: the whole environment runs in a browser tab, and hosting, a database with auth, domains and Expo for mobile come in one product with one bill. Stay if your team shares projects under Teams with admin controls, or if a Pro plan's token allowance covers your month comfortably; the open alternatives here move the model bill to you and the setup to your machine. And if cost is the reason you are looking, Bolt's own $9 Lite plan on its open-source Forge models is open to new sign-ups until 14 October 2026, which may be enough on its own.

#1★ TOP PICK

Dyad

A free desktop app builder that runs on your machine, with any model and no token meter of its own.

93
OPEN SOURCEApache-2.0 (src/pro under FSL-1.1-ALv2)SELF-HOSTLOCAL-FIRST

Dyad is a local, open-source AI app builder that describes itself as an alternative to v0, Lovable and Bolt that runs on your own computer. The loop will feel familiar: you chat, it builds and previews the app, and you can roll back versions. The difference is where things live. Every project is a regular Git repository in a folder on your machine (~/dyad-apps by default), and you bring the model: Google Gemini, OpenAI, Anthropic, OpenRouter, a ChatGPT subscription, or local models through Ollama or LM Studio, so there is no Bolt-style token allowance, only your provider's bill. It starts from React and Vite or Next.js templates, connects Supabase or Neon for a database and auth, can turn a web app into a hybrid mobile app with Capacitor, and deploys through GitHub to Vercel or any other host.

⌁ Dyad runs anywhere Node.js runs, and its FAQ suggests a cloud model such as Gemini or OpenRouter if your machine is not powerful. Local models through Ollama or LM Studio are optional; Dyad's own docs warn they are resource-intensive and that smaller models may struggle to follow its instructions.

Strengths

  • +Your project is a normal Git repository on your own disk, not a workspace on someone else's servers
  • +Any model, including a free-tier Gemini key, a ChatGPT subscription or a local model, so cost is yours to control
  • +Supabase and Neon integrations for database and auth, and hybrid mobile apps through Capacitor
  • +Very active: v1.18.0 shipped on 5 October 2026, and the repository has about 21.7k GitHub stars

Trade-offs

  • −You install a desktop app plus Node.js, where Bolt needs only a browser; macOS and Windows are supported, while Linux is experimental and does not auto-update
  • −JavaScript apps only, per its FAQ; mobile means hybrid apps via Capacitor rather than Bolt's Expo route
  • −The Pro features in the repository's src/pro folder are fair-source (FSL-1.1), not open source, and the free agent mode is limited to 20 messages a day
  • −No hosting of its own; you deploy through GitHub to Vercel or another host and manage that account yourself
Free and open source; bring your own API key or a ChatGPT subscription, or run a local model. The free Basic Agent is listed at 20 messages a day. Optional Dyad Pro is $20/month with 200 AI credits, and Dyad Max $79/month with 900. Verified on dyad.sh/pro 2026-10-06.

bolt.diy

The official open-source edition of Bolt.new: the same in-browser builder, run yourself, with any model.

78
OPEN SOURCEMITSELF-HOSTLOCAL-FIRST

bolt.diy is the official open-source version of Bolt.new, published under StackBlitz Labs and maintained as a community project, which makes it the closest match to Bolt's interface: chat, an editor, a terminal and a live preview of Node.js-based web apps in one browser tab. The difference is that you run it (Node.js and pnpm, or Docker) and choose the model for each prompt from more than 20 providers, including Anthropic, OpenAI, Google, OpenRouter, and Ollama or LM Studio for local models. Projects download as a ZIP, connect to Git, link to Supabase, and deploy to Netlify, Vercel or GitHub Pages. Like Bolt, it runs apps inside StackBlitz's WebContainer API, and StackBlitz licenses that separately: production use in a for-profit setting needs a commercial licence.

⌁ bolt.diy itself is light: a local Node.js server or Docker container serving a browser UI. With a cloud model it runs on modest hardware. Local models through Ollama or LM Studio need a capable GPU or plenty of unified memory, and the README lists better performance for smaller models as planned work.

Strengths

  • +The closest thing to Bolt's own interface, from the same company's open-source organisation
  • +Choose the model per prompt from more than 20 providers, including local Ollama and LM Studio
  • +Download any project as a ZIP, connect Git and Supabase, and deploy to Netlify, Vercel or GitHub Pages
  • +An active community project: about 19.9k GitHub stars, with commits landing this week

Trade-offs

  • −Its runtime, the WebContainer API, is proprietary; StackBlitz requires a commercial licence for production use in a for-profit setting
  • −No one-click install: you run it from source with Node.js 22.12+ and pnpm, or Docker; the last tagged release and desktop build (v1.0.0) date from May 2025
  • −Its README lists the move from single model calls to an agent-based system as still in progress, so it is less autonomous than Bolt's own agents
  • −No hosting, database or domains of its own; Bolt Cloud's conveniences become your setup work
Free and open source (MIT); you pay your model provider, or nothing beyond hardware with a local model. StackBlitz requires a separate commercial WebContainer API licence for production use in a for-profit setting; prototypes and proofs of concept do not need one.
#3

Google AI Studio

Google's free, hosted prompt-to-app builder, if a Gemini-only tool and Google's free-tier terms suit you.

25
SOURCE-AVAILABLEProprietary (hosted service)

For Bolt users who like that nothing needs installing, Build mode in Google AI Studio is the closest hosted equivalent at no cost. It turns a prompt into a full-stack web app (a React front end and a Node.js server by default) or a native Android app in Kotlin and Jetpack Compose, with a live preview in the browser, and it can provision Firebase Firestore and Firebase Authentication, sync two ways with GitHub, export a ZIP, and deploy to Cloud Run. Google's billing page says AI Studio usage is free of charge unless you link a paid API key. The trade-offs: it is built around Google's Gemini models, and on the free tier Google's terms say your prompts and outputs may be used to improve its products and may be read by human reviewers.

Strengths

  • +Nothing to install and no subscription: free in the browser unless you link a paid key
  • +Full-stack by default (React plus a Node.js server), and native Android apps rather than hybrid ones
  • +Two-way GitHub sync and ZIP export; a downloaded app runs on any host once you set GEMINI_API_KEY
  • +Firebase Firestore and Google sign-in can be provisioned for you

Trade-offs

  • −Built around Gemini; Google's Build mode guide describes no other model provider
  • −On the free tier Google may use your prompts and outputs to improve its products, human reviewers may read them, and its terms say not to submit sensitive or confidential information
  • −A hosted Google service you cannot self-host; deploying from AI Studio means Cloud Run, billed by usage
  • −When you share an app, its Gemini API calls count toward your own usage limits
Free to use unless you link a paid API key; deploying to Cloud Run is billed by Google Cloud based on usage, and apps that call paid models can incur costs. Verified on ai.google.dev 2026-10-06.

Questions people ask

▸ Why isn't bolt.diy, the open-source Bolt, the top pick?

It is the closest in shape, and it is genuinely open under MIT. We recommend Dyad first for three reasons we could verify on 2026-10-06. bolt.diy runs apps inside StackBlitz's WebContainer API, which needs a commercial licence for production use in a for-profit setting. Its last tagged release and desktop build (v1.0.0) date from May 2025, so a current version means running from source. And its README still lists the move from single model calls to an agent-based system as in progress. Dyad shipped v1.18.0 on 5 October 2026 and has an agent mode. For personal projects and prototypes in a familiar interface, bolt.diy is an excellent fit.

▸ Can I move an existing Bolt project into Dyad?

Usually, with some care. Download the project as a ZIP or sync it to GitHub from Bolt, then use Dyad's import feature, which its docs say works for apps built with Lovable, v0, Bolt or anything else. Importing is marked experimental and supports Node.js-based JavaScript apps that start with an npm run dev script; Dyad generates an AI_RULES.md file describing your stack if the project has none. If your Bolt app uses Bolt Database, see the next question first.

▸ What happens to my Bolt Database if I move?

Bolt lets you claim a Bolt Database into your own Supabase account, which requires a Pro or Teams plan. Once it is in Supabase, Dyad and bolt.diy can both connect to it, since both integrate with Supabase. Connecting a different Supabase database inside Bolt replaces the existing connection and may cause data loss, so claim rather than reconnect, and take a backup before you change anything. (Bolt help centre, read 2026-10-06.)

▸ Will a local model work as well as Bolt's agents?

Not for most people. Dyad's own documentation warns that local models are resource-intensive and that smaller ones may struggle to follow its instructions, and bolt.diy lists better performance for smaller models as planned work. A local model is the right choice when privacy or zero running cost matters more than quality. Otherwise a cloud key is the practical route: Dyad's docs recommend Google Gemini for its free tier, and you can also connect a ChatGPT subscription.
