EU-sovereign by default. Open by design.
Your code, your data, and your choice of AI. Build a real full-stack app from a chat, ship it to a public URL, and own the code plus your whole database as one SQLite file — with no hidden markup on the AI you already pay for.

Every competitor marks up the AI — and bills you when it breaks your app
The category buries a markup in credits, then charges you again when the AI fixes its own mistakes. DevBX shows the real price and lets you choose the provider. Here's the honest matrix.
| AI pricing | Hidden markup on fixes | Code export | Backend portable | EU host | Dev/prod + DB rollback | |
|---|---|---|---|---|---|---|
| Lovable | credits / msg | yes | ✓ (GitHub) | Supabase (yours) | ✓ Sweden* | ✗ |
| bolt.new | tokens | yes (3× rewrites) | ✓ (GitHub) | Supabase (yours) | ✗ US | ✗ |
| v0 (Vercel) | credits | yes | ✓ (Vercel git) | Supabase (coupled) | partial / CLOUD Act | code only |
| Replit | effort-based | yes | code only | ✗ locked-ish | ✗ US | ✗ |
| Base44 (Wix) | dual credits | yes | frontend only | ✗ locked | ✗ US | ✗ |
| DevBX | ✓ real price (EU gateway or BYO key) | ✓ no markup | ✓ yes | ✓ own SQLite file | ✓ EU | ✓ both |
*EU company, US infra (Supabase/AWS) — see why EU region ≠ EU-resident. Competitor facts mid-2026; verify before relying on them.
Why DevBX is different
No hidden AI markup
You see the real provider price — we don't mark AI up and bury it in credits like the others. Pick an EU-hosted gateway at cost or bring your own flat-rate key.
Your code, data, and choice of AI
Export your source code and your entire database as a single SQLite file, anytime — and pick the AI provider you build on. No vendor-locked backend holding your data hostage.
Real dev/prod + rollback
Break dev freely; prod stays up. Promote with one click and roll back code AND data. The safety net the headline failures were missing.
EU-sovereign by default
Your code and your database stay on EU infrastructure. Choose an EU-hosted AI provider (incl. a European Mistral model) to keep inference in the EU too — or opt into a cheaper US provider. Your call.
From a sentence to a shipped app
No terminal. No DevOps. You describe it; we build and host it.
Describe it
Tell DevBX what app you want, in plain language. No terminal, no setup.
The agent builds it
An AI agent builds your app on a server we provide, on a blessed deploy-correct template with auth, database, and conventions wired in.
Ship + own it
Deploy to a public URL with preview and one-click rollback. Export your code + SQLite file whenever you want.
More than a prompt box
Most AI builders stop at generating a screen. DevBX verifies, ships and operates a real app.
The agent tests its own work
It drives a real browser to click, fill forms and catch errors — and can read your production logs to debug, with fixes you approve.
Batteries included
Auth, database, file uploads, email, payments, background jobs and PDF — hand-written into every app. No SDKs, no vendor backend.
Edit by pointing
Click any element in the live preview to tell the agent what to change, or edit copy inline.
The category's own words
We didn't invent the pain. Builders did — verbatim.
It deleted our production database… then claimed rollback was impossible. I explicitly told it eleven times in ALL CAPS not to do this.
I spent $30 in a single day just to add a couple of category pages. The new pricing model is insanely worse.
Each time I'd click the 'Fix' button I'd spend a credit and watch a new error pop up — a never-ending chain reaction.
this thing is predatory… I just spent $25 in two small changes… zero backend code.
the exported code won't run on another platform without significant redevelopment.

v0 makes beautiful UIs. DevBX ships the whole app — without the hidden AI markup.
Read comparison →DevBX vs Replit
The agent that deleted a production database vs. one-click rollback of code and data.
Read comparison →DevBX vs Base44
Base44 keeps your backend. DevBX gives you the whole database in one file.

A flat monthly platform fee plus a starter AI allowance — then the AI at the real provider price, or your own flat-rate key. No hidden markup, no surprise bill.
