Best AI Code Review Tools

How we picked

We picked based on which tools have a verified, currently published pricing structure specifically relevant to code review, since cost predictability matters as much as feature quality when you're evaluating a review tool for regular use. Cursor and GitHub Copilot are the two tools in this roundup with fully documented pricing, and they take genuinely different approaches: Cursor's Bugbot is a dedicated review feature billed separately as usage, while Copilot folds review-adjacent capability into its standard chat and completion tiers.

If you're deciding between these two more broadly, not just for code review, our full Cursor vs GitHub Copilot comparison covers the rest of the feature set, and Cursor vs Windsurf and Claude Code vs Cursor are worth reading if you're considering other agent-first editors alongside these two.

The shortlist

Two tools make this list because they're the only ones with verified, currently published pricing relevant to code review: Cursor, with its dedicated Bugbot feature, and GitHub Copilot, whose review-adjacent capability lives inside its standard chat and completion tiers.

Cursor (Bugbot) — Cursor is an AI-first code editor forked from VS Code, and its Bugbot feature is a purpose-built code review tool rather than a general chat capability repurposed for the job. The catch is that Bugbot is billed as usage on top of your plan, so it's not a flat included cost the way a subscription tier usually is. You can test it on the free Hobby tier, which requires no credit card, before deciding whether the usage cost is worth it for your team's pull request volume. Once you're past evaluation, Pro at $20/mo adds extended Agent limits and frontier model access, and Teams at $40/mo per user adds SSO, centralized billing, and usage analytics — useful if you want visibility into how much Bugbot usage is actually costing across a team.

GitHub Copilot — Copilot doesn't ship a dedicated code review product the way Bugbot does, but it runs as a plugin inside VS Code, JetBrains IDEs, and Visual Studio, so you can use its chat and agent features for review-style work without leaving your current editor. The free tier includes 2,000 completions a month plus limited chat and agent usage, which is enough to get a feel for the workflow. Pro at $10/mo includes unlimited completions and next edit suggestions plus a $15/mo AI credit allowance that premium chat and agent features draw from — and that's the cheapest paid entry point among mainstream AI coding assistants covered here.

If you're weighing which of these fits a team already invested in a particular workflow, our Cursor alternatives roundup covers other options worth considering beyond just these two.

What to watch out for

The biggest thing to watch out for with Cursor's Bugbot is that usage-based billing means cost scales with how much review activity you actually generate, not a flat per-seat number you can budget confidently in advance. That's fine for a team that reviews a manageable, predictable volume of pull requests, but it's worth testing on the free Hobby tier first to get a real sense of what your usage pattern would cost before committing budget to it.

With GitHub Copilot, the trap is assuming "unlimited completions" on Pro means unlimited everything — premium chat and agent work draws from a separate $15/mo AI credit allowance, and heavy review-style chat usage can burn through that quickly, pushing you toward Pro+ at $39/mo or Max at $100/mo for a larger allowance. If your team's actual usage is closer to constant back-and-forth chat about a diff rather than occasional completions, budget for the higher tiers rather than assuming Pro's $10/mo covers everything.

More broadly, neither tool is a substitute for a human reviewer catching architectural or business-logic issues that require understanding intent beyond what's visible in the diff. Both are best treated as a first pass that catches obvious bugs, style inconsistencies, and common mistakes, freeing up human review time for the judgment calls that actually need it. Test either tool on a real pull request from your own codebase before rolling it out broadly — the usage-based and credit-based pricing models on these two make it hard to estimate true cost from a features page alone, and a short trial period is the cheapest way to find out.

It's also worth thinking about team size before committing. A solo developer or very small team can reasonably test Cursor's Bugbot on the free Hobby tier and just watch the usage numbers for a few weeks, since there's no credit card commitment to walk back. A larger team evaluating either tool should run the trial against a representative sample of real pull requests — not a cherry-picked easy diff — so the usage or credit consumption you observe actually reflects what a full rollout would cost. Skipping this step is the most common reason teams get an unpleasant billing surprise a month or two after adopting an AI review tool.

Finally, remember that pricing on both of these tools has changed before and will likely change again — Cursor and GitHub Copilot are both iterating quickly on their AI feature sets. Revisit your choice periodically rather than assuming today's tier structure and cost will hold indefinitely, and check each vendor's own pricing page directly if you're making a decision more than a few months after reading this.
