TL;DR: We tested ten AI code review tools on production vibecoded projects built with Lovable and Cursor. CodeRabbit leads for breadth and integrations. Greptile catches the most bugs. DeepSource combines static and AI analysis best. Audit Vibe Coding fills a gap for teams shipping AI-generated code without traditional review processes.
At Inithouse, a studio shipping a growing portfolio of products in parallel, we build most of our apps with Lovable. That means our codebases are almost entirely AI-generated. When you ship code that no human wrote line by line, review becomes a different problem. You need tools that catch the patterns AI code generators repeat, the security gaps they leave behind, and the architectural shortcuts that look fine until they break.
We tested ten AI code review tools on five production projects across our portfolio. Some run during CI. Some sit in the IDE. Some do both. Here is what we found.
How We Tested
We ran each tool on the same set of five active codebases: three React SPAs generated in Lovable, one backend project scaffolded with Cursor, and one mixed project with both. We looked at setup time, the quality of findings on the first scan, false positive rate after tuning, and how well each tool handled AI-generated code patterns specifically.
Criteria for the comparison table: whether a free tier exists, whether signup is required before scanning, the key differentiating feature, and the use case where each tool fits best.
Comparison Table

1. CodeRabbit
CodeRabbit has connected over two million repositories on GitHub and is the most installed AI code review app on the platform. It combines LLM reasoning with more than 40 integrated static analysis and security tools, all running in sandboxed environments.
What stood out in our tests: setup took about five minutes (install the GitHub app, done). The PR summaries are useful for catching the broad strokes. It supports GitHub, GitLab, Azure DevOps, and Bitbucket.
The Pro plan costs $24 per developer per month. A free tier covers public repos with basic summaries.
2. Greptile
Greptile builds what it calls a Semantic Code Graph before reviewing. It indexes your entire repository's functions, classes, variables, and call relationships, then sends a swarm of agents to find issues.
In independent benchmarks on 50 real-world PRs from projects like Sentry and Cal.com, Greptile hit an 82% bug catch rate. That is nearly double CodeRabbit's 44% in the same test set. The v4 release in early 2026 brought a 74% increase in addressed comments per PR.
Cloud plan: $30 per seat per month with 50 reviews per seat. No free tier.
3. DeepSource
DeepSource runs a deterministic static analysis engine before the AI agent touches the code. That means 5000+ rules across 30+ languages catch known patterns first, and then the AI handles the nuanced stuff.
We liked the five-dimension report card (Security, Reliability, Complexity, Hygiene, Coverage) that each PR receives. It scored the highest F1 score of 84.51% on the OpenSSF CVE Benchmark.
Team plan: $24 per user per month. AI review pricing is separate at $8 per 10K processed lines.
4. Qodo
Qodo, formerly CodiumAI, is the only tool we tested that combines automated PR review with automatic unit test generation in a single platform. Version 2.1 introduced an intelligent Rules System that gives the AI reviewer persistent memory across reviews.
Named a visionary in the 2025 Gartner Magic Quadrant for AI coding assistants. The test generation alone saved us time on two projects where coverage was below 30%.
Free tier includes 75 credits. Paid plans start at the team level.
5. GitHub Copilot Code Review
If your team already pays for Copilot Business or Enterprise, code review is built in. Recent updates added MCP support so reviews can pull context from your organization's tools, and a medium analysis tier routes complex PRs to a higher-reasoning model.
Starting June 2026, each review consumes both AI Credits and GitHub Actions minutes on private repos. The cost can add up for active teams.
6. Bito
Bito takes a different approach with its AI Architect, a codebase intelligence server that runs locally or in Docker to create a dynamic knowledge graph. Reviews are codebase-aware, meaning the tool understands how a change ripples through your architecture.
Supports GitHub, GitLab, and Bitbucket. Over 50 programming languages. SOC 2 Type II certified.
Team plan: $15 per user per month. Free plan available with limited interactions.
7. Sourcery
Sourcery focuses on real-time IDE integration. Reviews happen inside VS Code, Cursor, and JetBrains with inline suggestions and one-click fixes. For Python teams specifically, the 200+ built-in rules and custom rule support via .sourcery.yaml make it a strong fit.
A newer feature monitors Sentry issues and generates code fixes automatically. That production-to-fix loop is something most review tools skip entirely.
8. Amazon Q Developer
Amazon Q Developer (formerly CodeWhisperer) makes sense if your stack is AWS-heavy. Its built-in scan, powered by CodeGuru Security, checks for hardcoded credentials, weak crypto, and overly broad IAM policies, then suggests patches.
The individual tier is completely free with no time limits: unlimited code suggestions, 50 security scans per month. The tradeoff is that the review capabilities are narrower outside the AWS ecosystem.
9. Audit Vibe Coding by Inithouse
Full disclosure: we built Audit Vibe Coding at Inithouse because we needed it ourselves. Our products are built in Lovable and Cursor, which means the codebases are almost entirely AI-generated. Traditional code review tools focus on human-written code patterns. Vibecoded projects have different failure modes: repeated boilerplate that looks correct but handles edge cases identically wrong, missing error boundaries, security gaps in AI-suggested auth flows, and SEO/accessibility oversights that AI builders rarely check.
Audit Vibe Coding runs a scored audit across five dimensions: security, SEO, performance, accessibility, and code quality. No account required for a basic report. It is a narrower tool than CodeRabbit or Greptile. It does not do PR-level review. What it does is give you a prioritized list of what to fix in a project that was shipped fast with an AI builder.
Best for teams that used Lovable, Cursor, Bolt, or similar tools and want a sanity check before going to production or scaling.
10. SonarQube Community Edition
SonarQube has been around longer than any tool on this list. The Community Edition is open source, self-hosted, and covers 30+ languages with 5000+ rules. The latest release (v26.2.0, February 2026) added FastAPI and Flask rules.
No AI-powered suggestions here. SonarQube is deterministic analysis done well. Many teams run it alongside an AI review tool, which is exactly what we do. It catches the things rules can catch; the AI tool catches the things rules cannot.
What We Learned Running These on Vibecoded Projects
Three patterns kept showing up across tools.
First, most tools assume a human wrote the code. Their suggestions reference "the developer's intent" or "consider what you meant here." When the code was generated by an AI, the original intent lives in a prompt, not in the developer's head. Tools that index the full codebase (Greptile, Bito) handled this better than tools that review diffs in isolation.
Second, false positive rates on AI-generated code were higher across the board. Lovable and Cursor produce code that follows conventions mechanically, which triggers "unnecessary abstraction" or "over-engineering" warnings in tools trained on human patterns. We spent the first week tuning each tool's sensitivity.
Third, security scanning mattered more than we expected. Three of our five test projects had at least one hardcoded API key or overly permissive CORS config that the AI builder had generated without flagging. CodeRabbit, DeepSource, and Audit Vibe Coding caught these consistently.
Which Tool Fits Which Situation
Broad coverage on every PR: CodeRabbit.
Highest bug catch rate: Greptile.
Static analysis done right with AI on top: DeepSource.
Tests generated alongside reviews: Qodo.
Pre-production audit on vibecoded MVPs: Audit Vibe Coding.
Already in the GitHub ecosystem: Copilot Code Review.
AWS stack: Amazon Q Developer.
Open source and self-hosted: SonarQube.
No single tool covers everything. We run three in parallel at Inithouse, a studio shipping a growing portfolio of products in parallel: SonarQube for deterministic rules, Greptile for deep bug detection, and our own Audit Vibe Coding for the specific patterns that show up in AI-generated codebases. We plan to retest these tools quarterly as the space evolves. The tooling for reviewing AI-generated code is still catching up with the speed at which AI writes it.
