Do Lovable, Bolt and Base44 apps work offline?

Last updated 3 November 2026.

Short answer: no, not out of the box. All three build a website whose data lives in a database on the internet. With no signal, the page may still show, but it cannot save anything.

That is not a flaw in any of them. It is what they are for: fast web apps that many people open in a browser. It only matters if the people using the app work where there is no signal, like a basement, a farm, a ship or a rural site.

What each one says about where your data lives

• Lovable connects each app to Supabase. Lovable’s own Supabase page calls it “a hosted PostgreSQL database” and says “Supabase provides the databases and servers behind your app.” It does not mention offline use.
• Bolt hosts the app and its database itself. Bolt’s Bolt Cloud page says “Bolt creates a database when your project needs one” and publishes the app at a bolt.host address. It does not mention offline use either.
• Base44 runs your app and its data on its own platform. We could not find a Base44 page saying its apps work offline. Several articles that quote Base44’s app-store guide say its phone apps are a wrapper around the website and that “full offline mode” is not supported yet. That is second-hand, so check with Base44.

Can you add offline yourself?

Yes, if you or a developer will write code. The usual route is a “service worker”, a small script that keeps a copy of the app on the device (Mozilla explains it here). That keeps the screens. It does not keep the data.

Saving records with no signal and sending them later is the hard part. You need a copy of the database on the device, a queue of changes, and a rule for when two people changed the same record. Tools like PowerSync and RxDB exist to add that to Supabase, and PowerSync’s own write-up is honest that it is real backend work. For a team that wanted an app without code, that is the job they were trying to skip.

When they are the right choice

• The app is for the public. A booking site, a shop, a sign-up page. Those are websites, and Lovable, Bolt and Base44 make good ones.
• You want the code. They give you code you can change. We do not.
• Everyone has signal. In an office, offline does not matter.

When you need it to work with no signal

Bionic Forms is an AI app builder too: you describe what you track in a sentence and it builds the forms, lists and views. The difference is where the data lives. Our desktop app for Windows, macOS or Linux keeps a full, encrypted copy of the database on the computer. Adding, editing, search, files and printing all work with no connection, for as long as you like. When it finds a connection, changes go up and come down by themselves. If two people changed the same record while apart, both versions are kept and a person picks.

Free covers unlimited apps and 10,000 entries per app. Business is $29 a month for the whole team, with unlimited users.

Where this is honest

• Offline is the desktop app only. In a browser, ours needs a connection too.
• No phone app yet. If your crew only carries phones, look at AppSheet or Power Apps, which do work offline on phones, with conditions.
• Building an app needs a connection. The AI that builds it runs on our server. Using it afterwards does not.
• No code to take away. You get a database and screens, not a code base. Your records can always be exported.
• We are small and pre-launch. We say plainly which parts are not finished.
