You open bolt.new in a browser and type what you want built. Bolt writes the app and a working version appears in a preview panel beside the chat a few minutes later. From there you keep talking to it — describe a change, or click the thing on screen you want different — and it rebuilds in place.
Bolt is an AI app builder from StackBlitz: you describe a website or web app in plain language and it writes the whole thing — the screens people see and the storage behind them — and puts it on a live web address.
Nothing is installed: it builds and previews your project inside your own browser tab rather than on a distant server, so a Chromebook is enough.
Your allowance is measured in tokens (a chunk of text, roughly a short word — how AI usage gets counted), and Bolt's documentation says most of yours goes on Bolt reading and syncing your project files. So the same request costs more in week three than on day one: there is more project to read.
It builds in JavaScript, the language of the web; back ends written in Python or PHP are not supported.
Free, and no card: sign in with Google, GitHub or email. The free plan gives a daily token allowance under a monthly ceiling, and unused daily tokens never carry over.
That is enough for one small app and a few rounds of changes, not a full day of building.
Pro is a monthly plan with a much larger token allowance, no daily cap and unused tokens rolling over. Bolt states that subscriptions are non-refundable, so do your deciding on the free plan.
Publishing is included, but free hosting is capped at a monthly visit limit Bolt sets, and free sites carry a "Made in Bolt" badge. Past the cap the site goes offline until the month resets.
Bolt's privacy policy (updated May 2026) says StackBlitz may use what you type and what the AI writes to improve the service, on anonymised data, and sends portions of any files you attach to outside AI providers. Its own instruction is the plainest summary: "Do not include secrets, API keys, passwords, or confidential information in prompts, source code."
Ownership is refreshingly plain: Bolt's documentation states that all code you create with Bolt and StackBlitz is your own, usable for any legal purpose including commercial ones.
Build a simple reading log: one page where I can add a book, mark it reading or finished, rate it out of five, and see what I finished this month.
Why this one: Bolt spends tokens reading and syncing your project files, so the first build on an empty project is the cheapest one you will ever run. Something small but complete leaves most of the day's token allowance for changes.
Tweak: Keep version one to a single screen.
Lets you point at things in the preview and change their text, colour, size and spacing.
Why this one: Bolt's documentation is specific: visual edits are free to make, and tokens are spent only when you save. Ten fixes made in one pass and saved together are charged once, not ten times.
Tweak: Finish the whole wording-and-colour pass before pressing save.
Show me the code for the page I just built.
Why this one: Bolt's tokens page says that once the day's limit is gone you can still edit your project's existing code in Code view, which doesn't use tokens — so a typo or a wrong colour is fixable at 4pm.
Tweak: Code view is read-only in Safari; edit in a Chrome-family browser.
