AI code review

Every pull request, reviewed against a running system.

More than a dozen static analyzers, a full read of every changed file, a blast-radius pass, two frontier models, and live probes against the preview. Six passes before a single comment is posted.

We tried CodeRabbit, Greptile and more code review tools than I can count. Qodex outperforms them all by a mile. Honestly, the only AI reviewer that runs the tests instead of guessing.

How Qodex reviews every pull request

Deterministic work is done deterministically. The models are spent on judgment, and nothing they claim is published until a running system agrees.

  1. Pass 01

    Static analyzers

    More than a dozen deterministic linters and scanners run first, per language.

  2. Pass 02

    Deep read

    Every changed file is read in full. No size gate, no truncation.

  3. Pass 03

    Blast radius

    A code-graph pass finds what else the change reaches: callers, callees, routes.

  4. Pass 04

    Two models

    An agentic primary and a second frontier model from a different lab, merged by fingerprint. Each finding is tagged with who found it.

  5. Pass 05

    Live probes

    Findings are probed against the preview deployment before they are trusted. Read-only, SSRF-guarded.

  6. Pass 06

    The gate

    A Check Run posts with the review and blocks the merge if you told it to, per repo, in .qodex.yaml.

Reviews are incremental: a push scores only the commits added since the last one. Repo conventions are mined from your own merged pull request history, so the second month reads more like your team than the first.

What it catches

One example review.

Three findings from one pull request, each with a severity, the exact line, and what the review did about it.

HighBroken access control
apps/api/src/routes/billing.ts line 214

The tenant id is read from the request body instead of the session, so any authenticated user can fetch another organization’s invoices by editing one field.

- const orgId = req.body.orgId
+ const orgId = req.session.orgId
Verified against preview deployment
MediumUnindexed query
apps/api/src/db/invoices.ts line 41

The new filter runs on every dashboard load and the column has no index. Blast radius: eleven call sites across billing and reporting.

Blast radius: 11 call sites
LowUnhandled rejection
webhooks/stripe.ts line 88

The retry path returns a promise nobody awaits or catches, so a failed retry is dropped without a log line.

Your team

Built for the way your team reviews

  • Verified, not asserted

    Findings are probed live against the pull request’s own preview before they reach you.

  • Fixes on the exact line

    Inline, committable suggestions, on the line that needs them.

  • A merge gate you configure

    Block on critical, warn on the rest, or observe only.

  • Monorepo native

    The review is scoped to the directory that changed.

  • Learns your repo

    Dismiss a finding once and it stops coming back.

Add-on

And it can run your tests too.

The same agent that reviews the pull request can run your API, UI and security scenarios against the preview and attach the evidence: the failing request, the response, or a screenshot. Replays are generated code with no model call, so the suite grows without the bill growing.

Security

Built to be trusted with your code.

  • Read access only

    The GitHub app asks for read access to pull requests, not write access to your source.

  • Encrypted and isolated

    Data is encrypted in transit and at rest on US servers, and isolated per project.

  • Never trains on your code

    Your code, findings and review history are never used to train models.

  • Bring your own key

    Use your own model key if you prefer. Every token is logged.

FAQ

Questions teams ask before switching.

What is AI code review?

An automated pass over a pull request that reads the change and posts feedback before a person reviews it. Most tools do this by reading the diff. Qodex runs six passes: static analyzers, a full read of every changed file, a blast-radius pass over the code graph, two frontier models, live probes against the preview, and a Check Run that can gate the merge.

How is this different from CodeRabbit or Greptile?

They read the diff and tell you what looks wrong. Qodex probes what the models claim against the pull request’s own preview deployment before it posts, tags each finding with which model found it, and can hold the merge until it is fixed. If you want, the same agent runs your API, UI and security scenarios against the preview and attaches the evidence.

Which static analyzers run?

More than a dozen deterministic linters and scanners, chosen per language. Named ones include semgrep, gitleaks and osv-scanner. They run first, before any model reads the change, so the deterministic work is done deterministically.

What does it catch that a diff-only reviewer misses?

Anything the diff alone cannot show. A tenant id read from the request body instead of the session reads as a clean diff; a live probe against the preview returns another organization’s invoices and the finding is verified. A new filter on a column with no index looks harmless in one file; the blast-radius pass counts the eleven call sites it slows down.

What do we have to install?

The GitHub app, which takes minutes. Nothing goes into your application and no runner goes into your CI. Merge gating is configured per repo in .qodex.yaml. The next pull request gets reviewed.

Can it block a merge?

Yes, if you tell it to. A Check Run posts with every review; in .qodex.yaml you choose to block on critical, warn on the rest, or observe only. Fixes arrive as committable suggestions on the exact line, so a blocked pull request clears quickly.

What happens to our code and data?

The app has read access to pull requests, not write access to your source. Data is encrypted in transit and at rest on US servers, isolated per project, and never used to train models. Live probes are read-only and SSRF-guarded. If you bring your own model key, every token is logged.
