Google AI Studio vs Bolt.new: Which Builds Real Apps in 2026?

Google AI Studio vs Bolt at a glance (November 2026)

Details come from Google's and Bolt's official documentation and pricing pages, read on November 7, 2026. Prices are in US dollars.

What Google AI Studio is now

Google AI Studio is the browser workspace for the Gemini API. Its Build mode, documented on Google's developer site, is the part that competes with Bolt.

• →Gemini-centred, but not documented as Gemini only: Google's Build mode page refers to Gemini throughout and does not say whether other providers' models can be used, so we do not claim either way.
• →Antigravity Agent: Google says the Antigravity Agent powers Build mode. Google lists context awareness, multi-file dependency handling and verified execution among its capabilities.
• →Web apps: by default a React frontend plus a server-side Node.js runtime. Android apps are Kotlin and Jetpack Compose projects, previewed in a browser-based emulator, installable on a device through ADB in the browser and publishable to the Play Store for internal testing.
• →Firebase: Firestore and Firebase Authentication (Sign in with Google) can be provisioned automatically. For Android apps, Firebase AI Logic and App Check let the app call Gemini without a raw API key.
• →Deploy and export: apps can be deployed to Cloud Run as a scalable service, synced both ways with GitHub (with AI-written commit messages and a conflict dialog), or downloaded as a ZIP. A ZIP needs the GEMINI_API_KEY environment variable set where you host it.
• →API keys: for new web apps using Gemini, the key is set up as a server-side secret and, in Google's words, is never included in client-side code. Apps built before May 14, 2026 are upgraded to this approach when their Gemini features are next changed.
• →Sharing: apps are private by default. People you share with can see and fork the code, and with edit permission they can change it.
• →Known gaps: AI Studio does not support real-time collaborative editing, and direct storage support is listed as planned. Camera and microphone access needs a declaration in metadata.json.

What Bolt.new is now

Bolt.new is made by StackBlitz. It builds in the browser and, through Bolt Cloud, also runs the hosting and backend.

• →Bolt Cloud: hosting at a free bolt.host address, domains, a database that Bolt creates when your project needs one, sign-up and login, file storage (public and private) and server functions. Stripe can be connected for payments.
• →Supabase: available on Pro and Teams plans if you prefer it to the Bolt database. Bolt's help page warns that connecting Supabase can replace an existing Bolt database connection, and there is no supported way to migrate a Supabase database to a Bolt one.
• →Code view and terminal: you can open, edit, create and delete files, and edits there use no tokens. Editing and the terminal need Chrome or another Chromium browser on a computer; in Safari and on mobile, Code view is read-only.
• →Stack: any JavaScript framework on the frontend and Node.js for the backend. Bolt says PHP and Python backends are not compatible.
• →Mobile apps: include "mobile app" in your first prompt and Bolt builds with Expo. Bolt says web projects do not easily switch to mobile afterwards. Publishing needs an Expo account plus Apple and Google developer accounts.
• →Agents: Standard and Max. Only Standard is on the free plan. Bolt does not name the models behind them.
• →GitHub: you can import a repository and Bolt commits each change that does not break the project, checking GitHub every 30 seconds for outside changes. Only the project owner can connect it.

Pricing explained, with a worked example

The two products charge for different things: AI Studio charges for Gemini usage and hosting, Bolt charges a subscription measured in tokens. All figures are as of November 2026.

• →AI Studio free: Google's pricing page lists Google AI Studio access in the free tier, with free input and output tokens on certain models, and says free-tier content is used to improve Google's products. Google's rate-limits page publishes no free-tier numbers and says limits can be viewed in Google AI Studio.
• →AI Studio paid: paid-tier content is not used to improve products. To leave the free tier you set up billing in AI Studio, either prepaying at least $5 or choosing postpay where offered. Tier 1 needs a linked billing account; Tier 2 needs $100 paid in total plus 3 days; Tier 3 needs $1,000 plus 30 days.
• →Shared apps cost you money: a Cloud Run deployment uses your API key for all users' Gemini calls, Google says paid models may incur costs when apps are shared, and Cloud Run pricing may apply.
• →Bolt free: $0 for 1M tokens a month with a 300K daily limit that does not carry over. Free hosting is capped at 10 GB of bandwidth and 333,333 requests a month, and sites go offline at the limit until the next billing cycle.
• →Bolt Pro: from $25 a month, starting at 10M tokens with no daily limit, or $216 a year for the 10M plan (about $18 a month) according to Bolt's billing help. Unused tokens roll over for two months. Hosting allows 30 GB and 1M requests a month, with pay as you go for more up to a cap you set. Larger monthly examples in the help center are $50 and $100 (the $100 plan lists 55M tokens).
• →Bolt Teams: $30 per member a month. Each member has their own token allowance and tokens are not shared. We could not confirm a Teams annual price.
• →Worked example, a free prototype: on Bolt's free plan, 1M tokens a month at 300K a day means a little over three days at the daily cap would use the whole month's allowance. On AI Studio's free tier, building costs nothing but Google does not publish the limits.
• →Worked example, a small app you share: on AI Studio the cost is Gemini calls made by your visitors plus any Cloud Run charges, so it rises with traffic. On Bolt Pro you pay from $25 a month, and hosting allows 1M requests a month unless you add pay as you go.

Pick Google AI Studio if

• →You want to start free and your app is built around Gemini features and Google's models.
• →You are already on Google Cloud or Firebase and want Cloud Run deployment and Firestore set up for you.
• →You want an Android app in Kotlin and Jetpack Compose with an in-browser emulator.
• →You want your code in GitHub from the start and are happy to continue in your own editor.
• →You are moving off Firebase Studio: Google says it sunsets on March 22, 2027 and existing workspaces can migrate to Google AI Studio or Google Antigravity.

Pick Bolt.new if

• →You want to read and edit files and run a terminal in the browser while the AI works.
• →You want one subscription that covers building, hosting, a database and sign-in, starting at $25 a month.
• →You need an iPhone and Android app built with Expo and published to the app stores.
• →You want a custom domain without Bolt branding, which needs a paid plan.
• →Your project is JavaScript end to end with a Node.js backend.

Pros and cons

How to choose

• →Decide the platform first. Android in Kotlin points to AI Studio; iPhone and Android through Expo points to Bolt.
• →Decide where it will run. If Google Cloud is your home, Cloud Run and Firebase fit; if you want one bill for hosting and building, Bolt Cloud does that.
• →Estimate traffic. AI Studio costs move with your visitors' Gemini calls; Bolt charges by plan, with hosting limits and optional pay as you go.
• →Check how you work with others. AI Studio teams share a GitHub repository; Bolt Teams adds admin controls but separate token allowances.
• →Try both free tiers with the same small idea before paying for either.

What changed recently, and what we do not know

• →Google says the Antigravity Agent powers Build mode, and Google's Build mode page was last updated October 26, 2026. Google's Gemini API changelog for September to October 2026 has an Antigravity Agent model update (September 17) and a paid-tier logging change (October 26), but nothing on Build mode pricing.
• →Apps built before May 14, 2026 move to the server-side API key approach when their Gemini features are next changed.
• →Bolt Forge, an agent on open-source models, ran as a research preview from September 14 to October 14, 2026. Bolt's help page says Pro plans lose Forge access on October 14, while people already subscribed to Bolt Lite ($9 a month) by then keep it. We could not confirm what Bolt has launched since.
• →From November 1, 2026, Link, a Stripe payment service, handles Bolt billing; Bolt says plans and token allowances stay the same. Bolt also added a model training setting, on by default except in the EU, UK and Switzerland, for content from October 7, 2026.
• →Bolt on mobile gained previews, publishing and version restore in mid October 2026; Code view, visual edits and databases stay desktop only.
• →Not verified: whether Build mode can use non-Gemini models, whether Build mode has its own usage cap, free-tier rate-limit numbers, the cost of Cloud Run for a typical app, a Bolt Teams annual price, and which Bolt plans include GitHub sync.
• →Bolt's pricing page offers a yearly toggle but no annual dollar amounts appeared in the page text we read; the annual Pro price comes from Bolt's billing help article.
• →We found no per-plan message or app counts in the pages we read, so treat the worked examples as rough illustrations, not quotes.

How this page was put together

We compared Google's and Bolt's official published information on November 7, 2026: Google's Build mode and Gemini API pricing, rate-limit, billing and changelog pages, Firebase's Studio notice, and Bolt's pricing page, help center and release notes. We did not test the products ourselves, and we did not use third-party reviews for facts. Prices change often, so check the linked pricing pages before you pay. Vibe Code Apps is an independent directory.
