Side-by-side rankings of AI builders, scored against a public methodology.

Asking whether an AI app builder has payments tells you nothing about whether it can run a marketplace. One collects money into your account, the other has to move it past you to a seller. Eight builders compared on documented marketplace paths, Stripe Connect and the money split.
Every AI app builder can send an HTTP request out. Far fewer let something on the internet call your app at a URL you control. Eight builders compared on inbound endpoints, plan gates, idle behaviour and signature verification.
Five open-source AI app builders scored on the three things that decide whether you can actually resell one: licence, whether the builder UI itself is open, and who runs the infrastructure the generated apps need.
If your internal tool will be audited, the feature to shop for is not the builder's audit log. Five of eight builders gate it behind Enterprise, and six of eight log who edited the project rather than who changed a record. A 2026 comparison across Lovable, Bolt.new, Replit, Base44, Bubble, Softr, v0 and Webflow on the axis that actually decides it: who owns the database.
Every AI app builder can show a user their own rows. That is not multi-tenancy. Multi-tenancy is two colleagues at the same company seeing the same records and nobody at a rival company seeing any of them. Only one of eight builders documents organisation-scoped access as a supported pattern.
Ask eight AI app builders where your data lives and most show you a dropdown. An AI app builder is four systems that can sit in four jurisdictions: workspace, database, files and model. The selector governs one of them. Three of the eight make the choice permanent. A criteria-based comparison across Lovable, Bolt.new, Replit, Base44, Bubble, Softr, v0 and Webflow.
Every AI app builder says it has audit logs. The phrase hides four separate promises: who changed the app, who changed the data, who signed in, and what your end users did. Only one of eight answers all four. A criteria-based comparison across Lovable, Bolt.new, Replit, Base44, Bubble, Softr, v0 and Webflow.
Seven of eight AI app builders say they support role-based access. The roles govern your teammates, not the users of the app you shipped. A criteria-based comparison of both layers across Lovable, Bolt.new, Replit, Base44, Bubble, Softr, v0 and Webflow.
Every AI app builder has an undo button. Most of them rewind your code and leave your database exactly where it was. We compare what eight builders actually document about restoring data, in their own words.
Eight AI app builders, three mechanisms for keeping an API key out of the browser, and a read-back rule that splits them three ways. Verified against primary vendor docs.
Every AI app builder says it has analytics. Three genuinely different products share the word: one measures your bill, one measures that people arrived, and one measures what they actually did. Eight builders compared on which you get, whether it records events, and how long the data survives.
Every AI app builder accepts a file. Almost none of them store it where you think. Eight builders compared on whose bucket holds the bytes, whether a file URL is the only permission protecting it, and what survives a delete, an export and a move.
