What Guard is planned to catch

Beyond missing semicolons.

Planned: catch the bugs your reviewer would miss

RACE CONDITIONsrc/queue/processor.ts:34
if (job.status === 'pending') {
await job.update({ status: 'processing' })
}

⚠ Read-modify-write without a lock. Two workers can both read 'pending'.

Fix: use a CAS update - UPDATE jobs SET status='processing' WHERE id=$1 AND status='pending'.

Features

A reviewer that never sleeps.

Reviews every PR on open

Planned to trigger when a PR opens, so findings are waiting when your reviewer arrives.

Context-aware

Designed to read the diff, the existing review thread, and surrounding code before commenting.

4 severity levels

Planned: Critical, Suggestion, Style, Test Gap. Not everything is urgent; Guard is designed to signal what is.

Optional fix branches

Planned: Guard will be able to open a follow-up PR with the suggested patch on critical findings. It will never auto-merge.

Per-repo profiles

Planned: mute rules, tighten severity, and customize comment style per repo.

Polyglot

Planned language support: TypeScript, Python, Go, Rust, Java, Ruby, PHP, Kotlin, Swift, C++.

Who it's for

For every team that ships code.

Solo founders shipping fast

Designed as your second pair of eyes, to catch the null check, the missing auth, the race condition you'd miss at 2 AM.

Small teams without a senior reviewer

The goal: junior PRs land with bugs caught before merge, and senior time stays on architecture, not catching typos.

OSS maintainers with high PR volume

Planned: contributor PRs reviewed as they open, with severity tags that make triage quick so you can merge confidently.

FAQ

Common questions.

Will Guard ever block a merge?

Not by default. Guard is designed to comment and tag severity. A planned, optional CI integration will be able to fail builds on critical findings if you want that gate.

How will I install it?

Guard is pre-launch. Join the waitlist and we will tell you when installs open.

Will it open fix PRs automatically?

Planned to be off by default and switchable per repo. When on, Guard will open a fix branch and link it from the review comment. You will still merge manually.

What about false positives?

Guard is designed to explain its reasoning every time, and a πŸ‘Ž reaction is planned to mute the rule for that repo.

Will Guard see my entire codebase?

As designed, it will index your default branch on install (read-only). The index will live in your dedicated tenant and be purged on uninstall. Private repos will never be used to train shared models.

How is it priced?

Guard is rolling out as part of the Enterprise plan. See /pricing, or talk to sales.
