Best AI app builders in 2026
For a full-stack web app built by chat, start with Lovable on its free plan of 5 daily credits. Replit Core at $20 a month adds hosting and 100+ integrations. For internal business tools with unlimited users, pick Zite. 10 of the 11 picks have a free plan, and 10 publish a USD starting price.
Almost every AI app builder meters work in credits, so the real cost depends on how much you rebuild. Differences show up in what you get on top: Replit and Floot host the app, Buildra and App0 let you take the source code, Choicely builds native iOS and Android apps, and BrainGrid writes a spec before coding. Free tiers range from 5 credits a day (Buildra, Lovable) to 100 building actions a day (Floot).
