Comparison · Saltcorn vs Bubble

The open-source Bubble alternative, without the lock-in.

All-in-one web and mobile applications, built on a platform you host yourself and keep. MIT-licensed, quicker to learn, and never someone else's to switch off.

MIT licence Self-hosted · web, iOS and Android
01 / Why leave

Three reasons teams move off Bubble.

Lock-in

Your business runs on a platform that can reprice or close at any time.

Saltcorn is MIT-licensed. The source, the data and the server are yours — there is no decision anyone else can make that takes your application away.

Learning curve

Months spent learning a tool as intricate as the code it replaced.

Saltcorn is closer to a spreadsheet: define tables, pick views, wire up actions. Most people build something real on day one.

Hosting

On-premises or behind the firewall? A cloud-only platform is simply out.

Run Saltcorn on your own hardware, in your own cloud tenancy, or on ours. Same software either way, with no telemetry.

02 / Side by side

Both build whole applications. Only one hands it over.

Feature Saltcorn Bubble
Platform type All-in-one — database, UI, workflows All-in-one
Licensing Open source, MIT Proprietary and closed
Learning curve About as steep as a spreadsheet Weeks to months before you are productive
Data model PostgreSQL you can query, back up and take with you The vendor's own datastore
Deployment Cloud, on-premises, or behind the firewall Vendor cloud only
Mobile apps Build straight to the App Store and Play Store Third-party wrappers, paid separately
Telemetry None — nothing phones home Usage measured by the vendor
What it costs Server hosting, and nothing else Tiered plans plus metered workload
03 / Predictable cost

Infrastructure you can budget for, not a meter you can't.

Bubble · tiers plus metering

A plan, and then a usage bill.

Starter $29 / mo
Growth $119 / mo
Team $349 / mo

List prices, billed annually — before workload charges, which rise with every action your app performs.

Saltcorn · any size of application

$0

100 rows or 10 million, one workflow or ten thousand: the licence fee does not change. You rent a server, not a quota.

MIT licence. No tiers, no metering, no renewal.

04 / Ownership

Your app, your data, your infrastructure.

The code

Nobody can withdraw it

Saltcorn and everything you build on it are yours under the MIT licence — running on a platform whose source you can read, fork and keep.

The data

Private by deployment

Self-host with zero telemetry, inside your own network. Regulated and on-premises requirements are met by where it runs, not by a promise.

The mobile app

Straight to the stores

Build the same application as a native iOS and Android app from the admin interface — no third-party wrapper, no extra subscription.

From user interviews
“Very easy to get started — easier than Bubble.”

05 / Switching

Questions before you move.

Is Saltcorn really easier to learn than Bubble?

That is what users tell us: "very easy to get started, easier than Bubble." You describe your tables, choose views over them and connect actions — the platform does not ask you to think like a programmer first.

Can it handle workflows as complex as Bubble's?

Yes. Saltcorn workflows are built in a graphical editor and run durably: they can wait for a human, run for days, and pick themselves up after an error instead of losing the run.

If it is free, how do I host it?

Install it on any Linux server — a small application is happy on a cheap VPS — or use Docker, your own cloud tenancy, or our hosting. Whichever you pick, the environment stays under your control.

Rebuilding a live app?

We'll do it with you.

The Saltcorn team can rebuild your application, move the data and hand back something you own.
