Cubic alternatives: 6 AI code review tools compared

You use Cubic, or you are evaluating it, and you want to see the options. This page compares six Cubic alternatives for AI code review, with prices checked in October 2026.

This page was written by the Revix team. Competitor facts are dated and linked.

Quick answer

The six Cubic alternatives here are CodeRabbit, Cursor Bugbot, Greptile, Qodo, Revix, and Sourcery. Tools are in A to Z order. Order is not a ranking.

• CodeRabbit: you need more Git hosts, plus IDE and CLI review
• Cursor Bugbot: your team works in Cursor and wants fixes to flow into its agents
• Greptile: you want a graph of the whole repo and end-to-end tests on the PR
• Qodo: you are buying governance across many repos and hosts
• Revix: you want every PR reviewed against rules mined from your own repo
• Sourcery: you want a lower per-seat price and GitLab support

We make Revix. Keep Cubic if you are on GitHub, like its comments, and use its fix and agent tools.

Where Cubic is strong

Cubic gives short, ranked PR comments and hands fixes to coding agents. As of October 2026, per Cubic's docs and cubic.dev:

• Team rules as custom agents. You write each rule in plain language, adopt community agents from a library, or link repo files.
• Learning from feedback. Cubic remembers your reactions and corrections.
• Fix loop. "Fix with cubic", fixes through coding agents, and threads that resolve when the issue is fixed.
• More than PR review. Local CLI review, Ultrareviews for risky changes, and an AI wiki.
• Free paths. Starter is free for 20 PR reviews a month, and public repos are free. Paid plans come with a 7-day trial.

In our test PR, Cubic posted in about 4 minutes and caught both planted issues. Its comments were the shortest of any tool.

Why teams look past Cubic

• GitHub only. As of October 2026, Cubic's docs list no GitLab, Bitbucket, or Azure DevOps support.
• Price per developer. Per cubic.dev, Team is $30, Pro $79, and Max $160 per developer per month billed yearly. The pricing page shows $40, $99, and $200 billed monthly.
• Line allowances. Each plan caps reviewed lines per developer: 40k, 80k, or 160k.
• Rules you write. Someone has to write each custom agent. The standard limit is 5 enabled agents per repo, per Cubic's custom agents docs.

How we compared

We checked each tool against its own docs and pricing pages on October 20 and 21, 2026.

The 6 Cubic alternatives

CodeRabbit

Pick it when you need Git hosts Cubic does not cover.

As of October 2026, CodeRabbit's docs list GitHub, GitLab, and Bitbucket, cloud and self-hosted, plus Azure DevOps. Per coderabbit.ai/pricing, it also reviews in the IDE and CLI. Essentials is $24 per developer per month billed yearly, and public repos are free. Cubic still wins on its custom agents library and fix loop. More in CodeRabbit alternatives.

Cursor Bugbot

Pick it when your team already works in Cursor.

As of October 2026, Bugbot's docs list GitHub, GitLab, Bitbucket including Data Center, and Azure DevOps Services. Autofix sends a Cloud Agent to fix what Bugbot finds. Rules live in .cursor/BUGBOT.md, plus rules Bugbot learns from your team. Billing is usage-based, with rates on Cursor's pricing page. Cubic still wins if you want a fixed per-seat price.

Greptile

Pick it when out-of-diff bugs are the pain.

Greptile builds a graph of your codebase for each review, per its docs. Its TREX agent can start your app in a sandbox, test the flows a PR touches, and post what broke. Greptile's docs list GitHub, GitLab.com, and Bitbucket Cloud on all plans. Per greptile.com/pricing in October 2026, Starter is free for one active developer, and Pro is $30 per seat per month with 50 credits. Extra credits are $1. Cubic still wins on short comments. More in Greptile alternatives.

Qodo

Pick it when you need governance, Azure DevOps, or Gerrit.

As of October 2026, Qodo's docs list GitHub, GitLab, Bitbucket, Azure DevOps, and Gerrit, with on-prem options.

Its Rule Miner learns rules from your pull request history. Per qodo.ai/pricing in October 2026, Pro Team is $30 and covers up to 30 users, with pooled credits at $0.012 each. There is a 14-day trial with no card. Cubic still wins on a free Starter plan and a simple per-developer price. More in Qodo alternatives.

Revix

Pick it when you want review rules from your code, without writing them first.

Revix reads your repo when you connect it and turns its patterns into review rules. Every PR is reviewed against them, and you can edit, add, or disable any rule. Comments link the written team rule they apply.

Revix supports GitHub.com, GitLab.com, and Bitbucket Cloud. Self-hosted editions and Azure DevOps are not supported yet.

Revix is SOC 2 Type II and ISO 27001 certified. Plans are €20 Starter and €40 Pro per seat per month billed annually, with a 14-day trial. See the pricing page. Cubic still wins on agent prompts, auto-fix, and CLI review.

Sourcery

Pick it when you want GitLab support at a lower seat price.

As of October 2026, Sourcery's docs list GitHub, GitLab, GitHub Enterprise Server, and self-hosted GitLab. Per sourcery.ai/pricing, Pro is $12 and Team is $24 per developer per month billed yearly. Public repos are free. Cubic still wins on custom agents and its fix loop.

One test PR, five reviewers

Cubic, Greptile, Revix, and Sourcery caught both planted issues, and Graphite caught one. Only Revix linked the team rule each comment broke. This is one small test, not a benchmark.

On October 8, 2026, we opened one small PR in a public Hono and TypeScript repo. It has two planted issues, and each breaks a rule the repo already has in writing:

• Pagination issue. The route hand-parses page and perPage instead of using parseQuery.
• Env issue. The service reads a setting straight from process.env instead of src/config/env.ts.

Each tool ran on default settings. Every comment is on the public test PR.

Cubic ranks both issues P2 and adds a collapsed prompt for AI agents. That helps if you hand fixes to a coding agent. Its comments do not name the repo's written rule.

We did not run CodeRabbit, Cursor Bugbot, or Qodo on this PR.

How to choose in two weeks

1. Pick two or three active repos, the same for every tool.
2. Run one tool per repo in week one, so comments do not collide.
3. Track comments accepted, comments ignored, and time to first useful review.
4. After week two, ask your seniors: "Would you miss this if we turned it off?"

• Leaving GitHub, or on GitLab or Bitbucket: try CodeRabbit, Qodo, Revix, or Sourcery.
• Tired of writing rules: try Revix.
• Working in Cursor: try Bugbot.
• Missing cross-file bugs: try Greptile.

When to stay on Cubic

Stay on Cubic if your code lives on GitHub and authors act on its comments. Stay if your team hands fixes to coding agents through its prompts and auto-fix. Its free Starter plan also suits small teams testing AI review.
