Privacy First: Your code is never stored. Learn more

Stop bad code before it ships

Like a linter, but for your code logic. Catches bugs and anti-patterns instantly on commit - before you push, before CI, before anyone notices.

How It Works

Five-second setup. Zero friction. Private by default. Works seamlessly with VS Code Git. Push with confidence.
STEP 01

Install globally

npm install -g @commitguard/cli - Install once on your machine, use in any repo.

STEP 02

Initialize per project

Run `commitguard init` to set up necessary git hooks. Takes less than 5 seconds. Works immediately.

STEP 03

Configure (optional)

Run `commitguard config` to customize rules and prompts. Or use smart defaults.

STEP 04

Commit as usual

CommitGuard runs automatically on every commit. Reviews only your diff, not the whole codebase.

STEP 05

Get instant feedback

Quiet by default. Flags only risky changes. Fix the issue or override and push.

Privacy You Can Trust

We analyze diffs without storing anything. No training data, no third-party sharing. Your code is yours, period.

Only Diffs, Not Your Codebase

We only analyze the changes you made, never your entire codebase. Much safer than PR review tools that require full repository access.

No Code Storage

We never store, cache, or retain your code or diffs. Analysis happens in real-time and nothing is saved.

Never Used for Training

Your code will never be used to train AI models. We enforce strict zero data retention with our AI partners.

Your Data Isn't Our Product

We never sell or monetize your data. Your code is used only for providing commit analysis, nothing else.

Ship Faster, Break Less

Catch bugs, leaks, and embarrassing mistakes before they hit your repo. All at lightning speed.
  • Security Checks
    Catch vulnerabilities like exposed API keys and debug passwords before they hit your repo.
  • Architecture Checks
    Prevent structural anti-patterns and circular dependencies that become technical debt.
  • Code Quality Checks
    Block debug statements, merge conflicts, TODOs without context, and other issues that should never ship.
  • Performance Checks
    Detect slow or blocking code patterns before they affect users.
  • Privacy First
    We never store your code. Only diffs are analyzed in real-time with zero retention.
  • Developer-Friendly Overrides
    Bypass checks when needed with `--skip` flags or interactive options.
  • Fully Configurable Rules
    Enable, disable, or customize rules to fit your project and team standards.
  • Custom Rule Creation
    Build your own rules for naming conventions, patterns, or team-specific requirements.
  • Zero-Setup Protection
    Intelligent defaults provide instant protection. No config files required.

PR Reviews Are Broken

Feedback arrives too late, buried in noise, and never gets better. Commit reviews catch issues when they're still cheap to fix.
80%
of PR AI comments are noise, not real issues.

Feedback When It's Too Late

By the time PR review happens, you've moved on to the next feature.

PR Review 3 days later: "This should use a Map, not an array"
CommitGuard Instant feedback: "Array lookup in loop detected"

Bugs Compound Over Time

Stop bugs before they compound into bigger problems.

PR Review Bug hidden in 47-file PR discovered after merge
CommitGuard Caught in the 2-file commit where it was introduced

Smaller Diffs, Better Focus

Reviewing small commits is easier than large PRs.

PR Review Review 47 files at once, miss the bug in file 32
CommitGuard Review 2 files per commit, catch issues immediately

No Compound Learning

Catching mistakes immediately prevents repetition.

PR Review Find the same mistake in 5 different PRs this month
CommitGuard Catch it once, adjust your approach immediately

Custom Rules

Create rules that you know are important for your codebase.

PR Review Can't codify tribal knowledge in PR reviews
CommitGuard Custom rule: "No direct DB queries in controllers"

Ignores Your Style

Tools treat every codebase the same.

PR Review Suggests patterns you deliberately avoid
CommitGuard Learns you prefer composition over inheritance

Custom Prompts for Your Workflow

These are example prompts you can add to CommitGuard. Each prompt is evaluated only against the current. You can create your own custom prompts to fit your team's needs.

API Contract Drift

Example prompt

If function inputs or return values change in this diff, verify whether the public contract remains compatible or is clearly broken.

Surfaces breaking changes early, even in small diffs.

Pattern Consistency

Example prompt

Given the existing file style, flag new logic that breaks established patterns such as early returns vs nested conditionals.

Keeps logic style consistent within a file.

Logic Scope Creep

Example prompt

Flag diffs that introduce new responsibilities into an existing function instead of extending it minimally.

Prevents small changes from quietly increasing complexity.

Semantic Renames

Example prompt

If variables or functions are renamed, verify the new name accurately reflects the logic change introduced in this diff.

Catches misleading renames that obscure behavior changes.

Abstraction Leaks

Example prompt

Flag diffs that introduce low-level implementation details into high-level functions or vice versa.

Keeps abstractions clean as the code evolves.

Early Return Discipline

Example prompt

If early returns are added or removed in this diff, verify remaining code paths are still reachable and correct.

Avoids dead code and unintended execution paths.

BJ

B. Johnson

Full-Stack Developer

"Just tested out CommitGuard 🔥 You can define custom commit checks, and it checks with AI before committing unsafe code. I defined "Check if premium users are seeing premium and non-premium are seeing non-premium content" It directly detected it, when I committed. Works directly in VSCode."

PS

Priya Singh

Backend Engineer

"The AI checks are insanely fast and smart. I love that it respects our ESLint rules - no more false alarms."

EL

Ethan Lee

Full-Stack Dev

"Zero setup, configurable, and easy to bypass when needed. CommitGuard is a must-have for serious devs."

MG

Maria Garcia

DevOps

"The N+1 query detection alone is worth it. Found 3 performance bombs in the first week."

LO

Liam O'Connor

Frontend Engineer

"The performance checks are a game-changer. CommitGuard helps me ensure my code is not just functional but also efficient."

SM

Sofia Martinez

Junior Dev

"As a junior dev, CommitGuard has been an invaluable learning tool. It points out issues and helps me write better code."
