Is Diamond by Graphite worth it for small teams?

If your small team ships frequently and uses GitHub, yes—Diamond catches real bugs with low noise, and the one-click fixes save time. But the $20/user/mo Starter plan has limited AI reviews, so you may need the $40/user/mo Team tier for unlimited use, which adds up for larger teams. We'd recommend starting with the free Hobby tier to test signal.

Does Diamond by Graphite integrate with Slack?

Yes, Slack notifications are included starting on the Starter plan ($20/user/mo). You can get AI review summaries and alerts directly in Slack channels, so your team stays in the loop without context switching. The integration is documented on the pricing page.

How does Diamond by Graphite compare to CodeRabbit?

Diamond focuses on high signal with a <5% negative comment rate, catching real bugs like logic errors and security issues. CodeRabbit offers a free tier and broader language support, but users report more noise. Diamond's one-click fixes and custom rules in plain language (OWASP, style guides) give it an edge for enforcement, though at a higher price point.

What's the cheapest Diamond by Graphite tier?

The Hobby tier is free, but it's limited: personal repos only and limited AI reviews. If you need unlimited AI reviews and custom rules, the Team plan at $40/user/mo (annual) is the minimum. Starter at $20/user/mo adds org support but still limits AI reviews.

What are Diamond by Graphite's biggest limitations?

The main limitations are: AI reviews are limited on Hobby and Starter, so you need Team ($40/user/mo) for unlimited use. Customization is also Team+. It's GitHub-only—no support for GitLab or Bitbucket. The supported language list isn't published, so you'll need to test with your codebase.

Can Diamond by Graphite replace a human code review?

Diamond can catch many common issues (logic bugs, security problems, style nitpicks) with low false positives, making it a strong supplement. But it doesn't replace human judgment for complex architectural decisions or product context. Use it to automate the boring parts of review and let humans focus on higher-level concerns.

How long does Diamond by Graphite take to set up?

You can get your first AI review in under 3 minutes: just connect GitHub with one click (no config files), and Diamond starts reviewing new PRs immediately. Custom rules take about 10 minutes to configure. So you can see value in your first PR review session.

How do I migrate from CodeRabbit to Diamond by Graphite?

Simply connect your GitHub repository to Graphite Diamond and disable CodeRabbit's bot. Diamond will start reviewing your PRs immediately, and you can import custom rules from CodeRabbit (if any) by rewriting them in plain language. There's no data migration needed since both work on PRs.

Is Diamond by Graphite good for security-critical codebases?

Yes—Diamond is designed to catch security issues like exposed tokens, insecure patterns, and OWASP violations using custom rules. It also supports templates for OWASP security. The low noise ensures you notice the real alerts, making it valuable for security-critical projects.

Is Diamond by Graphite still active in 2026?

Yes — Diamond by Graphite is active in 2026, with a liveness score of 78/100 (healthy) as of August 29, 2026. It most recently shipped an update on April 1, 2026: “Introducing Code Tours”.

AI code review agent that flags real bugs and security issues on GitHub PRs with under 5% noise

78/100Safe BetFree · from $20/user/mo (annual)Freemium

Diamond delivers high-signal AI review that actually catches critical bugs, with a low false-positive rate backed by a public benchmark. Its one-click fixes, custom rules in plain language, and recent Code Tours and Cursor integration make it a strong upgrade over Copilot or CodeRabbit. However, unlimited AI reviews and customizations sit behind the $40/user/mo Team tier, so small teams should weigh per-seat costs.

The 30-second take

Biggest gripe

The free Hobby tier includes only limited AI Reviews, so you'll quickly hit quota walls if you review many PRs.

Price reality

Diamond's pricing fits growing engineering teams that already use GitHub and are willing to pay per seat for high-signal AI review. At $20/user/mo Starter and $40/user/mo Team, it's positioned above basic AI review tools like CodeRabbit (which offers a free tier for individuals) but below enterprise-grade code review platforms with similar AI features. Teams with many PRs per day will find the unlimited AI reviews on Team worth the premium.

In short

Diamond by Graphite — AI code review agent that flags real bugs and security issues on GitHub PRs with under 5% noise. Best for Engineering teams shipping frequently who want to catch bugs before production, GitHub-centric teams looking for high-signal AI review without extra context-switching, Dev teams standardizing best practices via custom rules (OWASP, style guides). Free to start; paid plans from $20/user/mo.

About Diamond by Graphite

FreemiumIntermediateNo APIWeb · CLI

Diamond by Graphite is an AI-powered code review agent that integrates directly with GitHub to analyze every pull request in seconds. It flags only real issues—logic bugs, potential edge cases, security problems like exposed tokens, performance bottlenecks, accidentally committed code, and documentation mismatches—keeping the negative comment rate under 5%. That means high-signal feedback without the noise that plagues generic AI reviewers. For engineering teams that ship frequently, Diamond turns hours of manual review into seconds of automated triage, complete with one-click suggested fixes and commit options. Recently, Graphite introduced Code Tours, which lets you review changes across multiple stacked PRs in a unified view, and integrated Cursor Cloud Agents so you can create, review, and ship code without leaving your PR.

Behind the Verdict

Diamond by Graphite stands out in the crowded AI code review space by focusing on signal over noise. The under 5% negative comment rate isn't just marketing—it's a metric the company publicly benchmarks, and testimonials from engineers at The Browser Company, Braintrust, and others echo that it catches real bugs others miss. The GitHub-native integration means you stay in your existing workflow, and one-click fixes with commit options turn review comments into immediate improvements. Custom rules written in plain language (OWASP, style guides) let you enforce team standards automatically, which is a big win for consistency. The recent Code Tours feature is a game-changer for teams using stacked PRs, letting you review an entire feature across multiple PRs coherently. Cursor Cloud Agents integration further reduces context switching, enabling create-review-ship flows without leaving the PR. On the downside, the free Hobby tier is limited, and the real power—unlimited AI reviews, automations, merge queue—requires the $40/user/mo Team plan, which adds up for larger teams. There's no mention of non-GitHub hosting or a direct API, so teams off GitHub are out. Overall, for GitHub-centric engineering teams that ship frequently and value high-signal feedback, Diamond is a strong investment, especially if you're already using Graphite for stacking.

Real-world workflow fit

Concrete scenarios for the personas Diamond by Graphite actually fits — and what changes day-one when you adopt it.

CTO at a 20-person startup

Your team opens 50 PRs a week, and you want to catch critical bugs before they reach production without a full-time reviewer.

Outcome: In less than a day, you connect GitHub, set up custom rules based on your style guide, and every PR gets an AI review within seconds. You catch a security issue (exposed token) that would have slipped through, and a logic bug that caused a rare edge case—thanks to the low false-positive rate, your team actually reads

Senior engineer at a mid-sized company

You use stacked PRs to break large features into smaller reviews, but coordinating feedback across the stack is painful.

Outcome: You enable Code Tours, which lets you review all PRs in a stack in a unified view. Diamond flags a logic error that only manifests when the full stack is merged, and you fix it with one click. You also use Cursor Cloud Agents to create and review a new PR without leaving the PR view, making your workflow seamless.

Engineering manager at a large org

You want to enforce OWASP security standards across all repos without nagging developers.

Outcome: You configure custom rules in plain language (e.g., 'Flag any use of eval') and enable security-focused templates. Diamond scans every PR and comments on security issues, with a <5% negative rate. Your team's security review time drops, and you use team insights to spot patterns and coach juniors.

Use Cases

Automatically catch logic errors and security vulnerabilities before they reach production.
Enforce team coding standards across every PR with custom rules written in plain English.
Accelerate code review cycles by accepting AI-suggested fixes with one click.
Reduce reviewer fatigue by filtering out non-critical comments like naming nits.
Get contextual AI feedback across stacked PRs, understanding dependencies between changes.
Review changes across multiple PRs using Code Tours for complex feature rollouts.
Create, review, and ship code without leaving the PR using Cursor Cloud Agents.

Hobby

$0/mo

Ideal for

Solo developer or personal projects on GitHub, exploring AI review without cost.

What this tier adds

Free entry point with personal repo support, limited AI reviews, and access to CLI/VSCode/MCP.

Starter

$20/user/mo (annual)

Ideal for

Small teams shipping production code who need org-wide repo coverage and Slack notifications.

What this tier adds

Adds all GitHub Organization repos, Slack notifications, team insights—but AI reviews remain limited.

Team

$40/user/mo (annual)

Ideal for

Growing teams that review many PRs daily and want unlimited AI, custom rules, and automation.

What this tier adds

Unlimited Graphite Chat and AI Reviews, plus AI review customization, automations, and Merge Queue.

Enterprise

Custom

Ideal for

Large orgs needing advanced security, compliance, and premium support.

What this tier adds

Adds advanced merge queue settings, ACLs, SAML, audit log (SIEM), GHES support, premium support, and custom contracts.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

The free Hobby tier includes only limited AI Reviews, so you'll quickly hit quota walls if you review many PRs.
Starter at $20/user/mo still has limited AI reviews, so you may need to upgrade to Team ($40/user/mo) for unlimited use, which roughly doubles your cost.
AI review customization (custom rules, automation, filters) is locked behind the Team plan, so you can't enforce team standards on Starter.
Enterprise pricing is custom and likely requires an annual contract with minimums, so small teams won't qualify.
Annual billing is 20% off, but monthly billing is available at a higher per-user price, so flexibility costs extra.
