Bolt.new
StackBlitz's prompt-to-app agent for shipping web apps in the browser.
What it is
Bolt.new turns a prompt into a full-stack app with auth, DB, and deploy in the browser. Best for non-engineers prototyping internal tools and indie hackers shipping MVPs.
Notes from using it
Bolt.new is the fastest path from "I have an idea" to "there's a deployed prototype someone could use." The browser-based runtime, instant deploy, and AI-driven setup of auth + database collapse what used to be a weekend project into 30 minutes. For non-engineers and indie hackers, the unlock is real.
Where it falls down: anything beyond standard CRUD. Custom backend logic, performance-sensitive workflows, integrations with services Bolt doesn't have first-class support for — quality drops fast. Teams that try to build serious production apps on Bolt typically migrate the codebase out within 3-6 months.
The token economics are the surprise for new users. Iteration-heavy projects (ten variations on a layout, multiple debug cycles) can chew through credits faster than expected. Plan to start with $20/mo Pro for evaluation, scale up with usage data once you know the actual consumption pattern. Don't budget Bolt as a daily-driver replacement for traditional dev tools.
Where it shines
- Zero-setup — runs entirely in your browser.
- Generates deployable apps, not just snippets.
Where it falls down
- Quality drops on complex backend work.
- Token costs add up on iteration-heavy projects.
