Strong fit. Describe an app and it builds and runs it in the browser, with the code editable and deployable from there.

Watch out: Credits burn quickly on iteration, and a generated app is a prototype until someone reads it. Pro is sold in token tiers from 10M a month up, so its price is the entry rate rather than the bill.

Watch out: Autonomy means less visibility into what changed — review discipline matters more, not less. Larger organisations may still be routed through sales rather than self-serve.

Built for this. The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use.

Watch out: Suggestions are strongest on common patterns and weakest exactly where your codebase is unusual. Pro and above bundle a monthly credit allowance, so premium-model work is metered on top of the seat.
Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for app development?
There is no single answer, which is why this page lists 7 rather than one: Lovable, Bolt.new, Replit, Cursor, Claude Code, Devin, GitHub Copilot. 5 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
6 of the 7: Lovable, Bolt.new, Replit, Cursor, Devin, GitHub Copilot. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
