Already have an app? Make it work.
Fix bugs and add features to apps made with Lovable, Bolt or Replit. Codeva changes only what's needed and proves it works.
"The signup form doesn't save new users."
Fix, improve and build apps with AI
Your AI-built app broke. Codeva fixes it, and proves it.
Codeva finds the bug, changes only the lines that need changing, and shows you proof that it works before you accept anything. No rewrites. No starting over. And when you want something new, Codeva builds it from a simple prompt, with the same checks.
Free plan included. A fix that fails never uses your credits.

One AI. Fix what you have, or build what you need.
Starting fresh? Just describe it.
Ask for a website, a page, a function or any code, like you would ask a chat AI. Codeva writes it, runs it and checks it before you get it.
"Make a landing page for my bakery with a WhatsApp order button."
When your app breaks, you usually have three choices.
Keep prompting the builder
The AI often rewrites working parts while it fixes one thing, and each try uses more of your credits.
Hire a freelancer
Finding someone good takes time, costs more, and you still can't easily check what they changed.
Codeva
A small, exact fix in minutes, checked before you see it, with proof you can read. If it can't fix it, it tells you, and you don't pay.
How it works
- 01
Connect your app
Link the GitHub repo your Lovable, Bolt or Replit project already syncs to.
- 02
Say what's broken
In plain words, like "the signup form doesn't save". Or ask for a new feature.
- 03
Codeva fixes and checks
It tries a few small fixes in a private copy and keeps only the one that passes every check.
- 04
You review and accept
See what changed and the proof. Your original is never touched until you say yes.
Every fix comes with proof.
AI that says "done" when it isn't is the biggest problem with coding tools today. Codeva doesn't ask you to trust it. It shows you.
Exactly what changed
Every edited line, side by side. Usually just a few.
Before and after
Screenshots of your app in a real browser, broken and fixed.
It still builds
The whole app is built and run, so one fix doesn't break something else.
No cheating
Checks are locked. Codeva can't edit them to make a fix look like it passed.
Simple plans. Same quality on every plan.
Free users get the same careful fixes as paid users, just fewer of them. A fix that fails never uses your credits.

Questions
Will Codeva rewrite my app?
No. It changes only the lines needed for the fix and shows you every one of them.
What if it can't fix my problem?
It tells you honestly what it found and what it tried. No credits are used.
Is my code safe?
Codeva works on a private copy in a sealed sandbox. Your real app stays unchanged until you accept the fix.
Which apps does it work with?
Apps made with Lovable, Bolt and Replit, connected through GitHub. More builders are coming.
Can it add new features too?
Yes. Describe the feature and Codeva adds it to your existing app, with the same checks and proof.
Can Codeva write new code from scratch?
Yes. Describe a website, a page or any piece of code and Codeva builds it. You can download the code, send it to GitHub, or keep improving it in chat.
Fix what you built. Build what's next.
