Base44 review 2026: acquired by Wix, and European data at $160 monthly

Base44 takes over a Salesforce or WordPress application with real data, something none of its competitors can do. But it charges for European data hosting at its highest tier, and its exit opens only one way.

Base44 lists five annually billed tiers: free, Starter at $16 monthly, Builder at $40, Pro at $80 and Elite at $160 (Base44 pricing page, consulted September 2, 2026). Our 2026 review turns on one line: storing data in Europe requires Elite.

What Base44 does better than everyone, including us

Base44 imports existing applications from Salesforce, HubSpot, Shopify or WordPress, taking real data rather than only structure and appearance. Documentation warns WordPress custom fields are left behind and the tool loads one hundred records per entity so you can inspect before committing. It can also start from Lovable or Bolt.new projects. No other tool in this category takes over operating business software with its contents, and Maestro does not either: we start from existing code, never a third-party application's data.

The category's clearest credit breakdown

Base44 separates two counters competitors mix. Message credits are consumed while discussing construction with the agent: a text revision costs around half a credit, a complex module around two, large-scale work three to four (Base44 credit documentation, consulted September 2, 2026). Integration credits are consumed when the application runs: a standard email around one, a Gemini model call around five, GPT-5.4 around fifteen, video five per second. Construction and operation costs are therefore separate. Monthly rates outside annual billing were absent from the pricing page on collection day, and we do not calculate them for you.

Europe as an option on the highest tier

By default, a Base44 application's data is stored in the United States: MongoDB for storage, Render for servers, Google Cloud for analytics (Base44 security page, consulted September 2, 2026). Elite and Enterprise workspaces may choose another region, including the EU and UK. Opting out of data use for model training is listed only at Enterprise. Base44 also lists SOC 2 Type II, ISO 27001, a GDPR data-processing agreement on request and PCI DSS. For practices or associations handling personal files, retain geography's price: $160 monthly before discussing anything else. At Maestro, projects do not leave your Mac, shifting the question.

Acquired by Wix, now building models

Wix acquired Base44 for $80 million in June 2025, when it was six months old with eight employees in Tel Aviv, and Base44 declared $150 million annualised revenue in May 2026 (TechCrunch, June 29, 2026; Wix's release was inaccessible during collection). On June 29, 2026, Base44 released its own Base1 model, trained according to its founder on tens of millions of platform user interactions. An acquired vendor changes trajectory, and this one now builds its own engine: two reasons to read terms before placing your production tool there.

The exit opens only one way

Code-host integration is advertised as bidirectional synchronisation, but documentation states no option exists to manually send Base44 updates to that repository. Synchronisation goes from outside into Base44, not the reverse. Two documented side effects: connecting the repository loses access to earlier history, and the feature requires Builder or above. Hosting outside Base44: we found nothing. Base44 also performs real checks on key journeys, unlike most competitors, but they are triggered manually after code, with scheduled execution promised later. This reverses our rule, where tests are written first.

What to verify before committing

Ask support three questions before paying and retain written answers: where data lives below Elite, how to retrieve the application when stopping, and the response language. Every page consulted September 2, 2026, pricing, security, documentation, was English, and we found no French interface; support was not tested, so we do not assume its language. If your application must take over an operating business tool with its data, Base44 remains the market's shortest route.
