Most teams don’t have a code quality problem. They have a code review throughput problem.
The people best placed to review a change are the busiest people on the team. So pull requests wait. The author moves on, the context goes cold, and when the review finally arrives it covers the lines that changed. Nobody looks at the forty other lines that depend on them. The bugs that reach production usually sit in exactly that gap.
So we built CodeReviewer to close it.
What it does
CodeReviewer connects to your GitHub organization and reviews every pull request on its own. You don’t need a bot command or a queue. The difference is what it reads first.
Before it comments, CodeReviewer builds your repository exactly as it will look after the merge. Then it follows the change outward: the callers of the function you touched, the other code paths that handle the same data, the tests that should have changed and didn’t. When it posts a finding, the finding comes with evidence:
- Where. The exact file and line, posted as a review comment in GitHub.
- What. A one-sentence statement of the problem.
- Why. The code elsewhere in your repository that proves the point (“the other fourteen money paths count in cents”).
- The fix. A concrete change you can apply.
If it can’t show all four, it stays quiet. We’d rather post fewer comments that are all worth reading.
Fixes that get checked before they land
A suggestion you have to copy, paste, adapt and push is still work. With CodeReviewer, a developer clicks Fix it on a finding and the fix is written for them. It’s type-checked, built if you’ve told us how, and committed to the branch. Fix all does a whole review at once. You can add instructions (“use the existing cents() helper”) when you want a say in how it’s fixed.
When a fix can’t be verified, CodeReviewer stops and tells a human exactly why. It won’t keep pushing broken attempts.
Tests that write themselves once
Review catches problems in the change. Tests catch problems in the product. So CodeReviewer writes those too.
Point it at a part of your app. It reads the code to learn what the feature is meant to do, signs in and clicks through your running app like a user, and records a suite of real test cases. You review the test plan first and keep the cases that matter.
Here’s how the cost works: authoring uses AI, replaying never does. Once a suite exists, you can run it nightly, on any schedule or on demand, as often as you like, at no extra cost. When your app changes and a test breaks, it gets repaired and re-verified. When a test is flaky, it’s benched so it doesn’t turn your whole suite red.
The same suites run on real Android phones, not emulators. You pair a phone by scanning a QR code. No rooting, no laptop.
Security and performance from the same suites
A suite that can sign in and walk through your app can do more than check features. CodeReviewer replays suites under throttling to measure real Core Web Vitals on authenticated pages. It gives your app a passive security grade from A to F. On domains you’ve proven you own, it runs active OWASP ZAP scans. It also builds a threat model from your own code, mapped to STRIDE and MITRE ATT&CK.
And it read the plan
Upload the spec for a project, and CodeReviewer splits it into requirements and checks every pull request against them. The project page keeps score: shipped, half-done and forgotten. You find the missing feature on Tuesday, not in the client demo.
Who it’s for
We built CodeReviewer at Techware Lab, a software delivery company, because we needed it ourselves. We ship for many clients at once, across web, backend and mobile, and our senior engineers had become the bottleneck. It now reviews our own work every day.
It fits well if you’re:
- An engineering team whose pull requests wait hours for a first look.
- A QA team that’s tired of babysitting brittle scripts.
- An agency that needs to show a client what shipped against the scope.
- A mobile team that needs tests on the phones your users actually carry.
Getting started
Every workspace starts with a 15-day free trial, and you don’t need a card. We onboard a few teams every week, so we can set you up properly: connecting GitHub, tuning the reviewer to your conventions, and authoring your first suite with you.
