AI Pull Request Review, Backed by Real Test Runs
Qodex (qodex.ai) reviews every pull request the way a senior engineer would: it runs your API and UI tests against the real app, probes the changes for security regressions, and files findings with evidence. 52 checks across two independent reviewer models, not diff-reading alone.
What it is
What is AI PR review?
AI PR review is an automated pass over a pull request that reads the change, flags likely bugs and risks, and posts feedback before a human reviews. It shortens the loop between opening a PR and knowing whether it is safe to merge. Most tools do this by analyzing the diff statically: they read the changed code, sometimes with a code graph for context, and comment on what looks wrong.
Qodex (qodex.ai, the agentic AI QA platform, not to be confused with Qodo) takes the review one step the others do not: it runs. On top of a 52-check review across two independent reviewer models, Qodex executes your API and UI tests against the real app for the PR and probes the changed surface for security regressions. The result is a review grounded in what the code actually does, with findings backed by the failing request, response, and screenshot, rather than a comment describing a suspicion. It is the pull-request front end of the wider agentic AI QA platform.
TL;DR
- AI PR review reads a pull request and flags issues before a human does. Diff-only tools stop at static analysis; nothing runs.
- Qodex reviews the diff and then executes: your API and UI scenarios against the real app, plus OWASP-aligned security probes on the change.
- Every finding carries evidence and a classification (real bug, stale test, or environment issue), so a red check means something real.
How it works
How Qodex reviews a pull request
The review is a three-step loop: you open a PR, Qodex reviews and runs your tests against the real app, and it files findings you can act on without re-verifying them by hand.
You open a pull request
The Qodex GitHub App picks it up and posts a status check. It already knows your repository and the test scenarios you have saved, so it starts with context, not a cold read of the diff.
Qodex reviews and executes
It runs 52 checks across two reviewer models, executes your API and UI scenarios against the real app, and runs OWASP-aligned security probes on the changed endpoints and flows.
It files findings you can trust
Real bugs land inline with the failing request, response, and screenshot; stale tests come with a suggested fix; environment issues are labelled as such. Chat with the agent, and gate the merge on findings when you want to.
On every pull request
What the review runs
Two independent reviewer models keep each other honest, and real execution turns opinions into verdicts. Here is what runs on the change before it merges.
52 checks, two reviewer models
52 deterministic and LLM checks run across two independent reviewer models, so a finding one model rationalizes away, the other still catches.
Real API and UI test runs
Qodex runs your API and browser scenarios against the running app for the PR, so the verdict is what actually happened, not what the diff implies.
OWASP-aligned security probes
The changed surface gets hostile-mode probes for IDOR/BOLA, auth bypass, and injection, with a pass meaning the attack was blocked.
Findings backed by evidence
Every finding carries the failing request, the response, and a screenshot, not just a comment describing a concern.
Failure classification
Each failure is filed as a real bug, a stale test the code outgrew (with a suggested fix), or an environment issue, so the review is not noisy.
Agentic chat on the PR
Ask the agent why it flagged something, or to dig deeper on a file, right in the pull request, and get an answer grounded in the run.
See the proof
See it on a real PR
Review comments are easy to claim and hard to trust. The test is whether a tool catches a real regression on a real pull request and shows you the evidence. Here is Qodex doing exactly that.
The difference
What execution catches that diff-only review misses
A static reviewer can suspect these; only a run proves them. Each of the four below is a bug class that reads as a clean diff and fails only when the code actually runs.
Authorization regressions
A removed access check reads as a clean diff. A scenario that requests another user’s record as the wrong user fails, and the IDOR is caught before merge, not in a pentest six months later.
Breaks across services
A response shape changes in one repo and quietly breaks a consumer in another. A static read of one diff cannot see it; a multi-step scenario that chains the two calls fails loudly.
Runtime regressions
Code that type-checks and looks correct can still 500 on a real request or return the wrong body. Executing the endpoint is the only way to know, and the review does exactly that.
Real bugs, not likely ones
A pattern matcher reports what might be wrong and leaves you to confirm it. A run reports what is wrong, with the request and response that prove it, so triage is reading evidence, not re-deriving it.
Side by side
Qodex vs diff-only reviewers
Diff-only reviewers, including the strong ones with a code graph, read your changed code and comment on what looks risky. That is genuinely useful. The difference is execution: Qodex runs your tests and security probes against the real app, so the review reports what happened, not only what the diff suggests.
| Diff-only reviewers | Qodex | |
|---|---|---|
| What the review works from | The diff and surrounding source, read statically | The diff, plus your tests executed against the real running app |
| Catching regressions | Pattern-matches likely bugs from the changed code | Runs API and UI scenarios and reports what actually broke |
| Security | Flags risky-looking patterns in the diff | Runs OWASP-aligned probes (IDOR/BOLA, auth bypass, injection) on the live endpoints |
| Evidence on a finding | A comment explaining the concern | The failing request, the response, and a screenshot |
| False positives | No run to confirm, so guesses stand | Failures classified as real bug, stale test, or environment issue first |
| After merge | Review ends at merge | The same scenarios replay on every future PR and deploy, deterministically |

In your pipeline
Where it fits your workflow
Qodex installs as a GitHub App and posts a status check on every pull request. The review is the same engine as the rest of the platform, so the scenarios it runs on a PR are the scenarios that keep running after merge.
On every PR
A status check and inline findings on the pull request, with results also routed to CI/CD, Slack, Jira, and Cursor (via MCP).
At the merge gate
On Pro Plus, gate the merge on findings and run custom pre-merge checks, so a real bug or a failing security probe stops the PR instead of shipping.
After merge
The same scenarios replay on every future PR and deploy, deterministically, so coverage compounds across the whole test suite.
Per-developer Pro and Pro Plus pricing, plus a free PR-summary tier, is on the pricing page.
