Built on Lovable, v0, Bolt or Cursor?

Take it to
the next level.

Upstream takes your prototype from Lovable, Claude, ChatGPT, or any AI builder and turns it into a real application. We get you your own domain, build a real database, and take real payments, all while making sure everything stays secure.

For builders shipping on

You got further than people said you could.

Building a working app without a dev team used to be impossible. You did it, and that’s not luck. Here’s the part nobody warns you about: these tools are built to make a great demo, not to survive a real business. The last stretch is exactly where we come in.

The part nobody warns you about

One careless read. A $14,000 surprise.

A single unprotected query, left running in the open, is all it takes. One spike of traffic or one bad actor, and the bill lands at the end of the month. This is the kind of thing that’s invisible right up until it isn’t.

Same traffic. Same users. 99.7% lower bill, because the waste got cleaned up before it shipped.

Looks done ≠ is done

The final 20% is the hardest.

What you generated looks finished. Underneath, the parts that decide whether a real business survives its first hundred users are usually missing. Here’s the checklist most AI builds fail:

Mistakes we’ve seen before2 / 9 production-ready
Anyone can pull your data.Your backend has no lock on the front door, so the wrong people can read what should be private.No auth on API routes
The keys to everything are sitting in your code.Your database password ships inside the app, where anyone can open it up and find it.Database keys in the client bundle
One bot can run up your bill.Nothing stops someone hitting your app a million times in a minute.No rate limiting
Fast with 10 users, frozen at 1,000.It feels quick today and grinds to a halt the moment you get traction.Unindexed queries
One mistake and your data is gone.No safety net if something gets deleted or a deploy goes wrong.No backups
It looks like you’re getting paid. You’re not.Payments are still in test mode, so no real money is moving.Payments in test mode
You find out it broke from angry users.Nothing tells you something’s wrong until someone complains.No error monitoring
What we make production-ready

Everything the demo skipped.

You keep the product you love. We finish the parts that take payments, stay online, and don’t leak or surprise-bill your customers.
