Your AI built the app.
We make it remember.
The missing backend for your Lovable, Bolt, v0, or Replit app. Describe what you need in plain English and get a live API with a database, logins, and AI search. Connected in under 2 minutes. No Supabase, no setup.
You'll get one link your app or AI can read and write to instantly. This is just your starting point. Your AI can change the schema, add columns, and add relationships later.
How it works
Tell us what your app needs to remember in plain English, or paste sample data if you have it. We figure out the rest.
We hand you a single link. Paste it into Lovable, Cursor, or ChatGPT.
Your AI wires it up and your app remembers everything: logins, posts, bookings, all of it.
madewith.dev runs on SimplestAPI for its backend and Logto.io for auth, wired up through our JWKS support. A real product, shipped on the same stack you get here.

Watch an app go from forgetting to remembering.
The app loses your data on refresh. Paste one doc. Now it saves everything.
A backend API for your app in seconds. Lovable, v0, Bolt, Cursor.
Edit your data like a spreadsheet.
See everything in a simple table and change it right there. Add a row, fix a typo, delete something you don't need. No database tools, no commands, nothing to install. If you can use a spreadsheet, you can manage your whole app's data here.
| title | done | priority |
|---|---|---|
| Ship docs | false | 1 |
| Fix the typo▎ | true | 2 |
| Email the list | false | 3 |
Copy one link into your AI. Done.
You never write code. Paste one link into Claude, ChatGPT, or Cursor and it reads your tables, your relations, and every endpoint, then wires them up. No setup to explain, no instructions to write.

→ answer + sql + rowsYour data is always yours.
Download everything anytime, in one click. It comes out as a plain SQL file that any database can read. If you ever move somewhere else, your data goes with you.
# one click → your whole database as plain SQL CREATE TABLE todos (id, title, done, priority); INSERT INTO todos VALUES (1, 'Ship docs', 0, 1); INSERT INTO todos VALUES (2, 'Fix the typo', 1, 2); INSERT INTO todos VALUES (3, 'Email the list', 0, 3); -- … every row, every table. Yours to keep.
It's a real REST API underneath: full CRUD, JSON mode, curl-friendly, pagination and filters, vector search, and end-user JWKS auth. No database setup, no migrations, bring your own auth provider.

“We run our own internal tools at protocolspring.com on it. Works great, and we've never had to think about the backend once.”

Questions
Do I need to know how to code? +
No. Describe your app in plain English and paste one link into your AI. Your AI writes the code, you never touch it.
Will this work with Lovable? +
Yes, and Bolt, v0, Replit, Cursor, ChatGPT, and Claude. If your app can call a URL, it works.
What happens to my data if you shut down? +
You can download your entire database as a plain SQL file anytime, in one click. Nothing is locked in. Your data is always yours to take and walk away with.
Is the free plan really free? +
Yes. Start with no credit card. Upgrade only when your app outgrows the free limits.
