Best Graphite AI Code Review Alternatives in 2026

The best Graphite AI code review alternatives in 2026 are Macroscope, CodeRabbit, Cursor Bugbot, Greptile and GitHub Copilot code review. Which one fits depends on why you are looking. Some teams love Graphite's stacked pull requests and only want a different AI code reviewer. Others want AI code review without stacked PRs at all, or without per-seat pricing, or without a reviewer whose parent company also sells them an editor.

This guide covers what Graphite's AI reviewer is today, what changed when Cursor agreed to acquire Graphite, who should look for a Graphite alternative and who should stay, and how each alternative compares on bug detection, pricing and fit. Every Graphite and CodeRabbit price below was read from the vendor's own pricing page on November 4, 2026.

TL;DR: Graphite AI code review alternatives in 2026

• Graphite's AI reviewer is now called Graphite Agent. Its docs say AI reviews are "powered by Graphite Agent", while its feature page still says "Diamond analyzes every pull request" (both read November 4, 2026).
• Graphite pricing is per seat. Hobby is free with limited AI reviews, Starter is $20 per user per month and Team is $40 per user per month (both billed annually), and only Team includes unlimited AI reviews.
• Macroscope is the closest alternative for GitHub teams that want a standalone AI code reviewer: 48.3% detection in its own benchmark versus Graphite Diamond's 18.3%, usage-based pricing with no seats, auto-approval and custom checks.
• CodeRabbit fits teams that want a thorough reviewer and accept per-developer pricing (Essentials from $24 per user per month billed annually).
• Stay on Graphite if your team runs on stacked PRs and the merge queue, and you treat AI review as a bonus rather than your main bug catcher.

What is Graphite's AI code reviewer?

Graphite's AI code reviewer is Graphite Agent, which Graphite has also marketed as Graphite Diamond, and it reviews pull requests inside Graphite's stacked-PR platform. Graphite's documentation says its AI reviews are "powered by Graphite Agent" (graphite.com/docs/ai-reviews, read November 4, 2026). Its feature page still says "Diamond analyzes every pull request" (graphite.com/features/ai-reviews, read the same day), so you will see both names in search results and in AI answers.

Graphite is best known for stacked pull requests: breaking a large change into a chain of small, dependent PRs that can be reviewed and merged in order. The AI code review sits on top of that workflow, alongside a merge queue on the Team plan. For teams already living in Graphite, that integration is the point. For teams that only want GitHub code review, it is a whole workflow to adopt in order to get one feature.

Did Cursor acquire Graphite?

Yes, Cursor agreed to acquire Graphite. Cursor's blog post dated December 19, 2025 says: "Graphite has entered into a definitive agreement to be acquired by Cursor. Graphite will continue to operate independently with the same team and product" (cursor.com/blog/graphite, read November 4, 2026). The graphite.com homepage now carries a banner that reads "Cursor Cloud Agents are now in Graphite" (graphite.com, read November 4, 2026).

That matters for anyone choosing among Graphite alternatives, because Cursor already sells its own AI code reviewer, Cursor Bugbot. That agreement puts Graphite and Bugbot in the same company. If you are leaving Graphite to get an AI code reviewer that is independent of your editor vendor, moving to Bugbot does not get you there. Our guide to Cursor Bugbot alternatives covers that side of the family.

How much does Graphite cost in 2026?

Graphite has four plans, priced per user, and only the Team plan includes unlimited AI reviews. As listed on graphite.com/pricing on November 4, 2026:

Graphite plan	Price	AI reviews	Other notes
Hobby	Free	"Limited AI Reviews"
Starter	$20 per user per month, billed annually	"Limited AI Reviews"
Team	$40 per user per month, billed annually	"Unlimited AI Reviews"	AI review customizations, merge queue
Enterprise	Custom	Custom	GHES support, SAML, audit log

The practical result: if AI code review is the reason you pay for Graphite, you are on Team at $40 per seat. A 20-person team on annual billing pays $800 a month, whether those 20 people open 50 pull requests a month or 500.

Who should look for a Graphite AI code review alternative?

Teams should look for a Graphite AI code review alternative when the reviewer, not the stacked-PR workflow, is what they are paying for. Four situations come up most often.

You want AI code review without stacked PRs

Graphite's AI review is built into a product whose core idea is the stack. If your team opens ordinary GitHub pull requests and has no plan to change that, a standalone GitHub code reviewer gives you the review without the workflow migration.

You want a reviewer that catches more bugs

In Macroscope's own Code Review Benchmark, Graphite Diamond caught 18.3% of real production bugs (21 of the 115 it was evaluated on), the lowest of the five tools tested. It was also the quietest reviewer, which some teams like. But if AI code review is meant to be a real bug-catching layer, detection is the number that matters.

You do not want per-seat pricing

Graphite's AI reviews scale with headcount. Teams with a few heavy committers and many occasional ones, or teams where coding agents open a large share of PRs, often find usage-based AI code review easier to justify.

You want your reviewer independent of your editor vendor

With Cursor agreeing to acquire Graphite, some teams want their GitHub PR review to come from a vendor that does not also sell the tool that wrote the code.

Who should stay on Graphite?

Stay on Graphite if your team depends on stacked PRs and the merge queue, and AI code review is a secondary benefit. Stacking is Graphite's core product, and no AI code reviewer on this list replaces that. You can also keep Graphite for stacking and add a separate AI code reviewer on the same GitHub repositories. AI code review tools run as GitHub Apps and do not conflict with each other, so trying an alternative does not require turning Graphite off.

What are the best Graphite AI code review alternatives in 2026?

The five Graphite AI code review alternatives worth evaluating are Macroscope, CodeRabbit, Cursor Bugbot, Greptile and GitHub Copilot code review. Each fits a different team.

1. Macroscope: a standalone Graphite alternative for GitHub code review

Fit: GitHub teams that want a standalone AI code reviewer with high detection, usage-based pricing, auto-approval and custom checks, without changing how they open pull requests.

What it does well:

• Detection. 48.3% (57/118) in Macroscope's own Code Review Benchmark, the highest of the tools tested and more than double Graphite Diamond's 18.3%. Macroscope explores the surrounding code in your repository, so it catches bugs across files.
• Approvability. Approvability auto-approves low-risk PRs and escalates risky ones, which speeds up review without stacking.
• Check Run Agents. Check Run Agents are custom AI checks written in plain-English Markdown that run as GitHub check runs and can block merges.
• Fix It For Me. Fix It For Me is an AI code fixer: it opens a fix PR, runs CI and iterates until tests pass.
• Spend controls. Cap spend per review or per PR, set monthly budget limits, turn off auto-review by repo or label, and exclude files. See controlling AI code review costs.

Pricing: Usage-based, no seats. Code Review is $0.05 per KB of diff reviewed in the default Balanced mode, with a 10 KB minimum per review. Reviews billed between September 29 and October 28, 2026 averaged 76¢ in Balanced mode and 55¢ in Budget mode. Every new workspace gets $100 in free usage, and qualified open-source projects can apply for free review. See pricing.

Limitations: GitHub only today. No stacked-PR tooling, so teams that want stacking keep a separate tool for it.

2. CodeRabbit: a per-developer Graphite alternative

Fit: Teams that want a thorough reviewer and are comfortable paying per developer.

What it does well: Close to the top of Macroscope's benchmark at 45.8% (54/118). It was also the loudest reviewer in that benchmark, so expect more comments to triage.

Pricing: As listed on coderabbit.ai/pricing on November 4, 2026: Essentials is $24, Team $48 and Advanced $72 per user per month billed annually; Essentials is $30 billed monthly. See CodeRabbit pricing for the full breakdown and CodeRabbit alternatives if you are weighing it against others.

Limitations: Per-developer pricing, like Graphite, scales with headcount rather than with review volume.

3. Cursor Bugbot: a Graphite alternative inside the Cursor family

Fit: Teams already standardised on Cursor that want review from the same vendor.

What it does well: 42.4% (50/118) in Macroscope's benchmark, third of five.

Limitations: Cursor has agreed to acquire Graphite, so Bugbot is a sibling of Graphite's reviewer rather than an independent alternative. Check Cursor's own pricing page for current terms.

4. Greptile: a codebase-aware Graphite alternative

Fit: Teams that want to evaluate another codebase-aware AI code reviewer.

What it does well: Greptile is a dedicated AI code review product, so it does not ask you to adopt a new PR workflow.

Limitations: In Macroscope's benchmark Greptile caught 23.6% (17/72), and it was evaluated on only 72 of the 118 bugs, so the rate rests on a smaller sample. Check Greptile's pricing page for current terms. See Greptile alternatives.

5. GitHub Copilot code review: the Graphite alternative with no new vendor

Fit: Teams already paying for GitHub Copilot that want AI review with no new vendor.

What it does well: It lives inside GitHub, so there is nothing new to install.

Limitations: It was not part of Macroscope's benchmark, so there is no like-for-like detection number. Check GitHub's plan page for which Copilot plans include code review. See GitHub Copilot code review alternatives.

How do Graphite alternatives compare on bug detection?

In Macroscope's own benchmark of 118 real production bugs, every Graphite alternative tested caught more bugs than Graphite Diamond. The benchmark covers 8 languages and counts a bug as caught when a review comment matches it. It is Macroscope's own evaluation, so treat it as one input and run tools side by side on your own PRs.

Tool	Bugs caught	Detection rate	Note
Macroscope	57 of 118	48.3%
CodeRabbit	54 of 118	45.8%	Highest comment volume
Cursor Bugbot	50 of 118	42.4%
Greptile	17 of 72	23.6%	Evaluated on 72 bugs only
Graphite Diamond	21 of 115	18.3%	Evaluated on 115 bugs; lowest comment volume

Graphite Diamond being the quietest reviewer is the flip side of its detection rate. Fewer comments means less noise, but on this dataset it also meant most real bugs went unflagged. For more on that trade-off, see AI code review false positives and signal-to-noise.

Graphite alternatives: side-by-side comparison

Graphite and CodeRabbit charge per seat; Macroscope charges per KB of diff reviewed. The table below uses only prices read on November 4, 2026 or published by Macroscope.

Tool	Pricing model	Price (read 2026-11-04)	Benchmark	Stacked PRs	Best for
Graphite	Per seat	Team $40/user/month annual (unlimited AI reviews); Starter $20 (limited)	18.3%	Yes	Teams built on stacked PRs
Macroscope	Usage-based, no seats	$0.05/KB Balanced, 10 KB min; 76¢ average Balanced review; $100 free usage	48.3%	No	GitHub teams buying review on its own
CodeRabbit	Per seat	Essentials $24/user/month annual, $30 monthly	45.8%	No	Teams wanting thorough reviews
Cursor Bugbot	See Cursor pricing	Not checked this run	42.4%	No	Teams on Cursor
Greptile	See Greptile pricing	Not checked this run	23.6% (72 bugs)	No	Codebase-aware review
GitHub Copilot	Copilot plan	Not checked this run	Not tested	No	Existing Copilot users

What does a Graphite AI code review alternative cost for a 20-person team?

For a 20-person team, Graphite Team costs $800 a month on annual billing, CodeRabbit Essentials $480, and Macroscope depends on how many reviews you run. The seat math is simple: 20 × $40 for Graphite Team and 20 × $24 for CodeRabbit Essentials, using the prices listed on November 4, 2026.

Macroscope bills per review. As an illustration, 300 reviews a month at the 76¢ Balanced average comes to about $228, and 600 reviews to about $456. Your own number depends on diff size and detection mode, which is why the cost per pull request guide walks through per-KB pricing in detail, and why the $100 of free usage is the easiest way to measure it on your own repositories.

Is Macroscope a good Graphite alternative?

Yes, for GitHub teams that want a standalone AI code reviewer with higher detection and usage-based pricing, and do not need stacked PRs. It is a reviewer, not a replacement for Graphite's stacking workflow. For the head-to-head, see Macroscope vs Graphite.

What changes when a team moves its AI code review from Graphite to Macroscope:

• Detection. 48.3% versus 18.3% in Macroscope's own benchmark.
• Pricing model. Per KB reviewed instead of per seat, with one prepaid workspace balance covering Code Review, Status and Agent.
• New primitives. Approvability for low-risk PRs, Check Run Agents for team rules that can block merges, and Fix It For Me for automatic fixes on the GitHub PR.
• Vendor independence. Review runs as a GitHub App on every pull request, whoever or whatever wrote the code.

What does not change, or gets worse:

• No stacking. If the stack is why you use Graphite, keep Graphite for that and run Macroscope alongside it.
• GitHub only. Macroscope reviews GitHub repositories today.

How do you evaluate a Graphite AI code review alternative?

Install the Graphite alternative on the same GitHub repositories as Graphite and compare both reviewers on the same pull requests for two weeks. You do not have to turn Graphite off. Then:

1. Count real catches, not comments. A comment that flags a real bug counts; a style nit does not.
2. Watch cross-file changes. PRs that change a shared type, function signature or config are where reviewers differ most.
3. Price a normal month. Multiply seats by the per-seat price for Graphite and CodeRabbit, and use your actual review count and diff sizes for usage-based tools.
4. Decide what you keep. If the stack and merge queue still earn their keep, keep Graphite for those and pay for AI review separately.

Setting up AI code review on GitHub takes a few minutes.

Conclusion: choosing among Graphite AI code review alternatives

The right Graphite AI code review alternative depends on what you are replacing. If it is the reviewer, Macroscope and CodeRabbit lead Macroscope's benchmark by a wide margin over Graphite Diamond, and Macroscope does it without per-seat pricing. If it is the vendor relationship after Cursor's acquisition agreement, Bugbot is not an exit. If it is the stacked-PR workflow, nothing on this list replaces it, and keeping Graphite for stacking while running a separate AI code reviewer is a reasonable answer.

Frequently Asked Questions

What are the alternatives to Graphite's AI code reviewer?

The main alternatives to Graphite's AI code reviewer are Macroscope, CodeRabbit, Cursor Bugbot, Greptile and GitHub Copilot code review. Macroscope fits GitHub teams that want a standalone reviewer with usage-based pricing and the highest detection in its own benchmark (48.3% versus Graphite Diamond's 18.3%). CodeRabbit fits teams that want a thorough reviewer on per-seat pricing. Bugbot is not an independent option, since Cursor agreed to acquire Graphite. Copilot fits teams that already pay for it.

What is Graphite Agent?

Graphite Agent is the name Graphite's docs now use for its AI code reviewer: AI reviews are "powered by Graphite Agent" (graphite.com/docs/ai-reviews, read November 4, 2026). Graphite has also marketed its AI reviewer as Graphite Diamond, and its feature page still uses the Diamond name.

Is Graphite Diamond still available?

Graphite's AI reviews are still offered, now under the Graphite Agent name in its docs. Its feature page still said "Diamond analyzes every pull request" on November 4, 2026, so both names point to the same AI review feature.

How much does Graphite AI code review cost?

As listed on graphite.com/pricing on November 4, 2026, Hobby is free and Starter is $20 per user per month billed annually, both with limited AI reviews. Team is $40 per user per month billed annually with unlimited AI reviews, AI review customizations and a merge queue. Enterprise is custom.

Did Cursor buy Graphite?

Cursor announced on December 19, 2025 that Graphite had entered into a definitive agreement to be acquired by Cursor, and said Graphite would continue to operate independently with the same team and product. Graphite's homepage now says "Cursor Cloud Agents are now in Graphite."

Can I get AI code review without stacked PRs?

Yes. Macroscope, CodeRabbit, Greptile and GitHub Copilot code review all review ordinary GitHub pull requests, with no stacking workflow to adopt. Macroscope installs as a GitHub App and starts reviewing new PRs right away.

Graphite vs CodeRabbit: which is better for AI code review?

On detection, CodeRabbit caught 45.8% of bugs in Macroscope's benchmark against Graphite Diamond's 18.3%, but CodeRabbit was also the loudest reviewer and Graphite the quietest. Both price per seat: CodeRabbit Essentials is $24 and Graphite Team $40 per user per month billed annually (read November 4, 2026). Graphite also gives you stacked PRs and a merge queue; CodeRabbit does not.

Can I use Macroscope and Graphite together?

Yes. Many teams keep Graphite for stacked PRs and run Macroscope as the AI code reviewer on the same GitHub repositories. Both run as GitHub integrations, so they do not conflict.

What is the best AI code reviewer for GitHub?

It depends on what you value. In Macroscope's own benchmark, Macroscope had the highest detection (48.3%), followed by CodeRabbit (45.8%) and Cursor Bugbot (42.4%). Run two reviewers on the same GitHub PRs for a couple of weeks and count real catches before deciding.

What are the best CodeRabbit alternatives?

The usual CodeRabbit alternatives are Macroscope, Cursor Bugbot, Greptile, GitHub Copilot code review and Graphite. See the full guide to CodeRabbit alternatives.
