Fixes failing tests
Point it at a red build. Zaprex reproduces the failure, finds the cause and opens a draft PR with the fix and a short write-up.
New from Ingot · Beta
Ship code while you sleep.
Zaprex is the AI coding bot that works on your repos while you're away. Give it a task or a nightly routine, and come back to a draft pull request.
Included in Ingot Pro+ and Ultra · Runs on Ingot, our own model
What it does
Your teammate on the night shift
Hand off the work that keeps slipping. Zaprex picks it up, does it properly, and leaves everything ready for your review.
Ships small changes
Bumps, refactors, renames, missing types, flaky lint. The chores you keep pushing to tomorrow, done before you're back.
Runs on a schedule
Set a routine like a nightly test-and-fix, and wake up to a tidy branch and a summary of what changed and why.
Follows up on reviews
Leave comments on the draft PR and ask Zaprex to address them. It picks up right where it left off.
How it works
Three steps. Zero babysitting.
- 01
Give it a task
From the Ingot IDE or the web: “fix the failing auth tests” or “add pagination to /orders”. Or pick a routine and a time.
- 02
It works in its own cloud machine
Each run gets a fresh, isolated machine with your repo. Zaprex reads, edits, runs your tests, and stops to ask before anything risky.
- 03
Review the draft PR
You get an in-app and email notification with a draft pull request. Keep it, ask for changes, or close it. It never pushes to main.
Features
Powerful when you need it. Safe by default.
Everything a background bot should do, and nothing it shouldn't.
Runs on Ingot, our own model
Built on Grok and tuned for code. Prefer another model? Switch per run from the model picker.
Isolated cloud machines
Every run starts clean in its own sandbox. Nothing touches your laptop, and nothing is shared between runs.
Draft PRs, never main
Work lands on a fresh branch as a draft pull request. Protected branches stay protected.
Approval cards
Installing packages, running migrations, network calls: risky steps pause and wait for your yes.
In-app and email alerts
Know the moment a run needs you or a PR is ready, in Ingot and in your inbox.
Routines
Nightly test-and-fix, weekly dependency updates, Friday test coverage. Pause or run now anytime.
IDE or web
Start runs from the Ingot IDE or from your dashboard in the browser, and follow the live log in either.
Admin controls
Turn Zaprex on or off, cap minutes and spend, choose allowed models and repos, and see every action in the audit log.
Routines
Set it once. Wake up to green builds.
Routines run on your schedule, in your time zone. Pause one, run it now, or change it whenever you like.

Security and approvals
You stay in charge. Always.
Zaprex is built to be trusted with real repositories. It works in the open, asks before it acts, and never merges on its own.
Never pushes to main. Zaprex only opens draft pull requests on new branches. Merging is always your call.
Asks before risky actions. Package installs, migrations, deletes and outbound network calls wait on an approval card.
Fresh sandbox every run. Isolated cloud machines that are wiped when the run ends.
Secrets stay secret. Zaprex refuses to store credentials in its memory and never writes keys into code.
Full audit trail. Every run, approval and admin change is logged, with spend caps and an off switch for admins.

FAQ
Questions, answered
What is Zaprex?
Zaprex is the background AI coding bot from Ingot, the open-source AI IDE. It works on your repositories while you're away and delivers its work as draft pull requests.
Which model does it use?
By default Zaprex runs on Ingot, our own model built on Grok and tuned for coding work. You can pick another available model for any run.
Can it push to my main branch?
No. Zaprex always works on a new branch and opens a draft pull request. You review and merge.
What counts as a risky action?
Things like installing packages, running database migrations, deleting files in bulk or calling outside services. Zaprex pauses and shows an approval card first.
Where does my code run?
In a fresh, isolated cloud machine created for that run and removed when it ends. Nothing runs on your computer.
Which plans include it?
Zaprex is part of the Ingot Pro+ and Ultra plans. See the Ingot pricing page for details.
Do I need a separate Zaprex account?
No. Zaprex uses your Ingot account: same sign-in, same plan, same data. Sign in on zaprex.dev or the Ingot portal and you're signed in with the same account.
How do I get it?
