Our in-depth review
Idea to live URL, in the browser
bolt.new, from StackBlitz, runs a full Node.js development environment inside your browser — no local setup at all — and turns a prompt into a working, deployable full-stack web app. It's one of the most talked-about tools of the vibe-coding era, and for getting from a rough idea to a live URL in a hurry, it genuinely delivers.
Strengths
You get a real, editable codebase that you own — not a black box — with live preview, one-click deploy, GitHub import and export, and npm package support. It's well-suited to full-stack web apps, and its large user base means there's no shortage of community examples, templates and momentum to draw on when you get stuck.
Where it strains
bolt meters usage in tokens, and the burn is steep: a single complex generation can consume a large chunk of your allowance before you've even started iterating, and it can loop on errors or lose coherence on bigger projects. Costs are hard to predict, and output quality tends to tail off as a project grows in size and complexity.
The UK data caveat
This is the weak spot, and for a UK business it matters. The consumer Bolt product carries no formal GDPR, SOC 2 or HIPAA certification, and your prompts are sent to third-party models (Anthropic). Parent company StackBlitz holds SOC 2 and offers self-hosted, SSO-secured deployment at Enterprise — but on the standard product there's no EU data-residency guarantee, so keep personal and confidential data out of it. If compliance is a hard requirement, Lovable or a self-hosted route is the safer choice.
Key features
- In-browser full-stack dev environment (no local setup)

GDPR & data residency
Where your data is processed: US; no EU residency on the consumer product. Self-host available via StackBlitz Enterprise
The weakest posture of the major app builders, and worth weighing: the consumer Bolt product carries no formal GDPR, SOC 2 or HIPAA certification, and prompts are sent to third-party LLMs (Anthropic). Parent company StackBlitz holds SOC 2 and offers self-hosted Kubernetes deployment with SSO at Enterprise. No EU data-residency guarantee on the consumer product — keep personal and confidential data out.
Our verdict
We rate bolt.new 3.5 out of 5. It's best suited to developers and makers who want to prototype and ship full-stack web apps quickly from the browser.
Visit bolt.new →Frequently asked questions
Is bolt.new free?
Yes, there's a free tier with a monthly token allowance. Pro is around £20/month with higher usage tiers above it; billing is in USD and metered by tokens, which complex apps consume quickly.
Do I own the code bolt.new generates?
Yes — you get a real, editable codebase with GitHub export, not a locked-in black box.
Is bolt.new GDPR-safe?
It's the weakest in our directory on this point: no formal GDPR/SOC 2 on the consumer product, and prompts are sent to third-party LLMs. For regulated data, look at StackBlitz Enterprise (self-hosted) or a tool like Lovable instead.
