bolt.diy vs Google AI Studio
Both are alternatives to Bolt.new. Here's how they stack up — verified facts, no spin.
Also searched as Google AI Studio vs bolt.diy — same comparison, one verdict.
bolt.diy is open source (MIT) and Google AI Studio is not (Proprietary (hosted service)) — so the real question is whether you want to own the ai app builders stack or rent it.
bolt.diy
The official open-source edition of Bolt.new: the same in-browser builder, run yourself, with any model.
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.
Google AI Studio
Google's free, hosted prompt-to-app builder, if a Gemini-only tool and Google's free-tier terms suit you.
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.
Side by side
6 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

bolt.diy edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
bolt.diy
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
Google AI Studio
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
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose bolt.diy
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Google AI Studio
if nothing to install and no subscription: free in the browser unless you link a paid key.
Neither, yet
if both carry a real cost you should weigh first — its runtime, the WebContainer API, is proprietary; StackBlitz requires a commercial licence for production use in a for-profit setting, and built around Gemini; Google's Build mode guide describes no other model provider. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
bolt.diy vs Google AI Studio — common questions
Is bolt.diy a better fit than Google AI Studio for ai app builders?
It depends on what you are optimising for, and the honest split is this: bolt.diy scores 78 to Google AI Studio's 25 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Google AI Studio earns its place on a different axis — nothing to install and no subscription: free in the browser unless you link a paid key. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
bolt.diy keeps its data local or in open formats, so leaving is an export rather than a negotiation. Google AI Studio keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Can I self-host bolt.diy?
bolt.diy can be self-hosted; Google AI Studio cannot, so it stays on the vendor's infrastructure whatever you do.
Are bolt.diy and Google AI Studio both alternatives to Bolt.new?
Yes — both appear in our Bolt.new comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Bolt.new and now choosing between the two replacements, which is a narrower and much easier question.
