What it does

Code review that actually ships

Not another linter. Not another bot that spams your PRs. Stackwise thinks like a senior engineer — catching real bugs, explaining trade-offs, and suggesting refactors before you merge.

Security vulnerability detection

Flags injection risks, insecure deserialization, auth bypass patterns, and credential leaks. Catches OWASP Top 10 issues before they hit production.

Critical findings only. No noise.

Cross-file bug detection

Indexes your entire codebase. Catches bugs that live in the seams between files, not just within the diff. Understands how your PR affects downstream services.

Full-repository context

AI refactoring suggestions

Identifies duplication, complex conditionals, and anti-patterns. Proposes clean, idiomatic rewrites that match your codebase's style and conventions.

One-click apply

Plain-English explanations

Doesn't just flag issues. Explains why it matters, what could go wrong, and what the safer alternative looks like. Junior devs learn from every review.

Context-aware, not generic

Learns your codebase

Adapts to your naming conventions, architectural patterns, and team standards over time. Gets smarter with every review it runs.

Custom rules, plain English

Team analytics

Track review velocity, catch rates, and recurring issues across your entire engineering org. Find the patterns that slow you down.

How it works

Up and running in 5 minutes

01

Install the GitHub App

One-click install from GitHub Marketplace. Select your repos. Stackwise requests minimal permissions — read access to pull requests only. Your code never leaves your infrastructure.

02

Open a pull request

Push your branch. Open a PR. Stackwise is triggered automatically. It reads the diff, indexes the relevant parts of your codebase, and posts a review — typically in under 10 seconds.

03

Apply or discuss

Each finding comes with severity, explanation, and a suggested fix. Apply the fix directly from the comment, discuss it with the AI in-thread, or dismiss it with context. Your call.

"Every engineering team has a review bottleneck. It's not the PRs that are too big — it's that nobody has time to really read them."

The bottleneck isn't review. It's the lack of a second set of eyes that never gets tired, never rushes, and actually understands your codebase.

faster AI review vs. waiting for a senior engineer's calendar

We believe every team deserves a senior engineer on every PR.

That's what we're building.

Why Stackwise

Not another Copilot wrapper

Copilot writes code. Stackwise reviews it. Different tools for different problems. We built the review layer that AI-generated code urgently needs.
