Govern your
AI code.

Claude, Codex, and Cursor can review a diff. GReview reads every PR against what the ticket asked for, your architecture and guardrails in GKS, your whole codebase, and every other open PR, then posts one prioritized review in minutes. The hand that writes the code is never the hand that checks it.

Reviewed against the ask

Every PR is checked against the ticket's business requirement, not only whether the code is clean. No coding agent does this by default; GReview gets the intent from Jira through GKS.

Through GKS

Inter-PR collision detection

Flags every other open PR touching the same functions, a conflict class point tools structurally can't see.

Unique to Garth

Your context, not the model's guess

Whole codebase, architecture rules, team guardrails, and scale and compliance guidelines, all served from GKS. One prioritized review, critical to low. The 4.2% false positive rate is context, not luck.

The brain matters

Maker-checker by design

The agent that wrote the code never signs it off. GReview reads only what the job needs through GKS and writes back only through your keys. Cloud, VPC, or on-prem.

Independent by design
A real review

This is what lands on the PR.

Not a wall of style nits. One assessment, findings ordered by what will actually hurt you in production, with the fix, the file, and the line.

Severity-first, so reviewers know where to look.

GReview opens with a verdict, then groups findings by impact. A hardcoded secret and a breaking API change surface first. Duplicate formatting logic sits at the bottom, where it belongs. Your reviewers read top-down and stop when the risk runs out.

Security that matters

Hardcoded live secrets, SQL injection, unsafe input handling, caught before merge, not in an incident report.

Breaking-change detection

New required parameters whose callers weren't updated: the runtime TypeError your tests would've found in prod.

Logic, performance & quality

N+1 patterns, edge cases, and duplicated logic, each with a concrete, apply-ready fix.

Overall Assessment

The goals are legitimate, but the implementation is critically flawed and should not be merged in its current state. It carries multiple severe security vulnerabilities plus breaking API changes that will cause runtime errors in production.

🔴 CRITICALSecuritycheckout.py:8
Hardcoded live Stripe secret key
A live secret key is hardcoded as a module-level constant and leaked further via a print statement, an immediate security-incident risk. Revoke and rotate the key, then move it to a secrets manager.
🔴 CRITICALSecuritybilling.py:24
SQL injection in process_bulk_billing
User IDs are interpolated directly into the query string. Use parameterized queries or an ORM to remediate.
🟠 HIGHIntegrationnotification.py:5
Breaking signature change to send_alert()
A new mandatory channel parameter is not reflected in its existing caller in billing.py, guaranteeing a TypeError at runtime. Update all call sites and add a regression test.
🔵 PERFPerformancebilling.py:22
N+1 query pattern at scale
A blocking loop issues one query per user (~5.0s for 1,000 users). A batched IN clause resolves it in a single round trip.

Nobody else does this

It sees the PRs your reviewers can't hold in their head.

A reviewer looks at one diff at a time. GReview knows every open PR that touches the same functions, before two of them merge and quietly break each other.

Reviewed against intent

It checks the code against what the ticket asked for.

Clean code that builds the wrong thing still ships the wrong thing. GReview reads the ticket's business requirement through GKS and reconciles every PR against it: what was asked, what was built, and what rode along that nobody asked for.

payment.py:88
Verdict: 2 of 3 criteria delivered, 1 gap, 1 change beyond the ask. Every line links to the ticket or the PR, so the reconciliation is auditable.
No coding agent does this by default

Claude Code, Codex, or Cursor only know the ticket if someone wires up MCP and keeps a skill current. GReview gets the intent from Jira through GKS on every review, with nothing for your developers to set up.

Maker-checker, by design

The agent that wrote the code is never the agent that signs it off. The check runs on your organisation's context, not the author's session, so it does not share the author's blind spots.

The same reconciliation, at release

GRelease runs Ask vs Built across a whole release train from the same GKS context, so "did we build what we promised" has one answer at the PR and at the freeze.

Beyond a linter

It reasons about how the code will actually run.

GReview profiles the change, ranks the real hot paths, and hands back a fix with the numbers to justify it, the kind of insight a static reviewer never surfaces.

The economics of review

Catch the regression in review, not in production.

A defect that reaches production costs many times what it costs to catch in review. GReview reads the whole codebase on the first pass, against your guardrails, so far more is caught before it ships.

Review comments acted on

GReview speeds your reviewers up. It does not replace them.

How it works

Every review runs through the governed boundary.

GReview never touches your systems directly. It reads through GKS, the governed knowledge layer you control, and posts back only through your keys.

1

Asks GKS

On a new PR, GReview requests the context it needs from GKS: your repository graph, architecture rules, guardrails, and the ticket behind the change.

2

Policy & guardrail check

GKS checks policy and guardrails at intake, releasing only what this job is authorized to see.

3

Pulls only the diff it needs

Scoped context: the diff, the relevant symbols, your coding standards, the ticket's intent, and open PRs, nothing beyond it.

4

Posts a scoped review

A prioritized, actionable review lands on the PR, written back to your environment through your key.

Configured in Garth Universe

Your repos, your rules. Set once, enforced on every PR.

Garth Universe is the control plane. Choose which repos GReview watches, author your own guardrails and architecture rules, decide when it runs, and route it through your own model keys.

Data Governance

Your data stays yours.

Agents never touch your systems directly. Everything reads through GKS, the governed boundary you control, and every action writes back only through your keys. Your own coding agents can read the same context over MCP. Sign-in is Google or Microsoft SSO, with roles and audit logs in Garth Universe.

Explore GKS →
01

You choose what connects

GKS ingests only the sources you authorize. Nothing you have not connected ever enters.

02

Only what the job needs

Each agent gets the exact data required to do its work, filtered at intake, and nothing beyond it.

03

Guardrails at the boundary

Agents read from GKS, never your host systems. Misuse stops at the boundary, not inside your stack.

04

Every action needs your keys

When an agent writes back to a system, it goes through credentials you provision, scope, and revoke at will.

Where GReview stands apart

Everyone owns a slice. Garth owns the layer.

Point tools each read one signal. GReview grounds review on the same shared brain as security, release, and ROI, so it sees what none of them can.
