7 Cursor Bugbot Alternatives for 2026: Flat-Fee, Self-Hosted, Open-Source and Multi-Platform AI Code Review Compared

Prices and platform support below come from vendor pages and third-party write-ups as read between 3 and 5 November 2026; where a figure is second-hand we say so. Every tool here changes its pricing often. Check the live pricing pages before you commit.

Why people go looking for a Bugbot alternative

Cursor Bugbot is a good product with a specific shape, and the search for alternatives almost always starts with one of five complaints about that shape. On 11 May 2026 Cursor removed Bugbot's seat fee and moved it to purely usage-based billing: an average run costs “$1.00–$1.50, depending on PR size and complexity,” individuals draw from included usage, teams from on-demand spend, and legacy $40-per-seat subscriptions switch at the first renewal after 8 June 2026. Cursor also says its high-effort mode “finds 35% more bugs.” That made Bugbot cheaper for light users and harder to budget for everyone else, because by default every push triggers a run and Autofix bills as Cloud Agent usage on top.

The other four reasons: you want to self-host or bring your own model keys; you want a review that can actually block a merge (Bugbot posts PR comments plus a Cursor Bugbot check that concludes “neutral” by default, so it never gates); your team does not use Cursor and does not want to buy into it for a reviewer; or you want open source. Platform coverage is less often the reason than people expect: per a competitor's October 2026 write-up (cubic.dev), Bugbot supports GitHub and GitHub Enterprise Server fully, GitLab on a paid GitLab plan (self-hosted GitLab needs Cursor Teams or Enterprise), Bitbucket Cloud in beta, Bitbucket Data Center on Teams/Enterprise and Azure DevOps Services in beta without Autofix. Rules live in BUGBOT.md files capped at 30,000 characters each and 100,000 per review, and there is a 14-day free trial.

The honest counterpoint first: if your team already lives in Cursor, wants Autofix, and your PR volume is low enough that $1 to $1.50 a run is noise, Bugbot is a sensible choice and nothing below will clearly beat it. The rest of this post is for everyone else.

7 Cursor Bugbot alternatives for 2026, grouped by what you are fixing

Fixing: unpredictable usage billing

1. CodeRabbit. The broadest review platform in this list and the most common first stop; the Bugbot vs CodeRabbit comparison goes deeper. Pricing as read 3 November 2026: Essentials $24, Team $48, Advanced $72 per developer per month billed annually, a 14-day trial, free for public open-source repositories. A seat is a seat however often someone pushes, which is the whole appeal after Bugbot. Self-hosting is Enterprise-only. The CodeRabbit alternatives round-up has the wider managed field.

2. Qodo Merge. The hosted version of PR-Agent. Per a third-party pricing write-up updated 20 October 2026, roughly $30 a month flat for up to 30 users plus credits at $0.012 each, a 14-day trial, Enterprise by quote. Credits per review are not published, so the flat part is predictable and the credit part is not.

Fixing: code that cannot leave your infrastructure

3. PURA. Self-hosted, GitHub-only, BYOK with your own OpenAI, Anthropic or Google keys, and priced as a flat platform fee metered by reviews: Starter $39 a month for 100 reviews, Scale $99 for 400, Pro $199 for 1,000, Enterprise above that. Model spend goes to your provider and is capped with budgets per team, repository and provider. It posts one ranked review per PR and is not a platform or an IDE; more at the end.

4. PR-Agent (open source). The open-source core of Qodo Merge, and the usual answer to “AI code review, open source.” Free to self-host as a CLI, Docker container, GitHub Action or webhook; supports GitHub, GitLab, Bitbucket, Azure DevOps and Gitea; runs on OpenAI, Claude, Gemini or local models via Ollama. You pay only model API costs and own the hosting and tuning. The open-source alternatives post covers the rest of that category.

Fixing: depth, noise or an existing contract

5. Greptile. Indexes the whole repository and reviews against it, the pitch being cross-file logic bugs. As read 3 November 2026: Pro sells credits at $1 each with no seat fee (Base review 1 credit, Plus 3, Apex 10), a free Starter tier for one active developer with 50 credits a month, a 14-day Pro trial, self-hosting only on Enterprise. Usage billing again, but in whole credits you can count; see Greptile vs CodeRabbit.

6. Macroscope. The quiet one. $0.05 per KB of diff reviewed with a 10 KB minimum (a Budget tier at $0.025/KB), caps of $10 per review and $50 per PR, $100 starting credit, free for open source. GitHub-only, no self-hosting. Still metered, but the per-PR cap is the ceiling Bugbot lacks; the Macroscope vs CodeRabbit post works the monthly numbers.

7. GitHub Copilot code review. If the organisation already pays for Copilot, the reviewer is in the bill. As reported by third parties from GitHub's billing docs in 2026: Pro $10, Pro+ $39, Business $19, Enterprise $39 per user per month; each PR review consumes premium requests at a 13× multiplier and, since 1 June 2026, GitHub Actions minutes on private repositories; the Free plan offers only selection review inside VS Code. Check GitHub's own docs; this is the one entry we did not read from the vendor directly.

Comparison table

The merge-gate column describes what each vendor documents, not a test we ran, and “not assessed” means our sources did not say. A check that blocks merging is something you wire up in branch protection, so confirm the tool posts a check at all.

How to pick, by scenario

• Budget predictability. A flat fee or seats: PURA, CodeRabbit or Qodo Merge. If you must stay metered, Macroscope's per-review and per-PR caps are the nearest thing to a ceiling.
• Self-hosting or BYOK. PURA if you want a product with a flat fee and budgets; PR-Agent if you want open source and are happy to run it yourself.
• Multiple platforms. CodeRabbit or PR-Agent; both cover GitHub, GitLab, Bitbucket and Azure DevOps on their standard plans.
• Deep cross-file review on demand. Greptile, with Apex reserved for the PRs that touch auth, payments or migrations.
• Quiet reviews. Macroscope, by design and by meter.
• Already paying for Copilot. Turn on Copilot code review first and check the premium-request spend before adding a second vendor.
• Already in Cursor, want Autofix. Stay on Bugbot and set a spend limit.

Whichever two you shortlist, run them on the repository that scares you; the trial guide explains how to make 14 days produce an answer.

Where PURA fits

Five of the seven tools above are managed services on their public plans: your diff, and in some cases your indexed repository, is processed in the vendor's cloud on the vendor's model. PURA is for teams whose complaint about Bugbot was the billing or the deployment model. It is self-hosted on your own infrastructure, BYOK with your own OpenAI, Anthropic or Google keys, and priced as a flat platform fee metered by reviews: Starter at $39 a month for 100 reviews, Scale at $99 for 400, Pro at $199 for 1,000, Enterprise above that, with budgets per team, repository and provider so the model spend stays where you put it. The full plan list is on the pricing page. It is GitHub-only, and it is not a platform or an IDE: it posts one ranked review per PR. If you want Autofix inside Cursor, GitLab support or an open-source codebase, pick from the list above. If the requirement is that the code stays home and the invoice stays flat, PURA is the comparison worth running next.
