Bolt.new alternatives

Almost everybody searching for a Bolt.new alternative is solving the same thing: a complex project can burn through a token allowance in one sitting. So the useful way to sort the field is by how the AI is billed, not by features.

Metered, bundled or yours

There are only three shapes. Metered means you pay per unit of thinking and you will ration it. Bundled means somebody else guesses your usage and prices the risk in. Yours means you already hold the subscription and no one is in between, which is the only one where iterating hard costs nothing extra.

Ura is the third shape. That is also its cost: without an existing Claude or Codex subscription there is nothing for it to run, and one of the metered tools will serve you better.

Is there an AI app builder with unlimited usage?

Not really, and be careful with anything advertising it. What exists is unmetered building on top of a subscription you hold directly, where the provider's own fair-use terms are the only limit and no reseller adds a second one.

Written in August 2026 and checked against each tool's own published pricing and documentation at the time. Both products change. If something here is out of date, it is a mistake rather than a tactic, and telling us fixes it.
