Best overall for AI-generated pull requests: Cursor Bugbot reviews GitHub pull requests, flags likely logic bugs, comments on issues, and can provide fixes in Cursor or through its Background Agent. For a second layer, pair it with a security-focused scanner that matches your code: Horusec for mixed stacks, Cppcheck for C/C++, Find Security Bugs for Java web applications, or KloudSec IaC Security for Terraform and CloudFormation. Distik is the most focused option for AI-generated pull requests when you want one risk-ranked merge signal.

|---|---|---|---|
| 1 | Cursor Bugbot | Logic bugs in GitHub pull requests | AI code review, low-false-positive focus, inline comments and fixes |
| 2 | Distik | AI-generated pull requests | One LOW, MED, or HIGH signal with ranked risk chapters |
| 3 | Horusec | Security scanning across mixed-language projects | Static analysis, key-leak checks, Git-history checks, CLI and CI/CD use |
| 4 | KloudSec IaC Security | AI-written Terraform or CloudFormation | Pull-request scans, IAM and public-access checks, AI-generated fixes |
| 5 | Find Security Bugs | Java web applications | 144 vulnerability types and more than 826 API signatures |
| 6 | Cppcheck | AI-written C and C++ | Static analysis for bugs, undefined behavior, dangerous constructs, and security standards |
1. Cursor Bugbot
Why It Fits AI-Generated Code
Cursor Bugbot is the clearest general choice when generated code arrives as a GitHub pull request. Its verified description says it is strong at reviewing AI-generated code, detects difficult logic bugs with a low false-positive rate, and finds bugs directly in GitHub. It comments on potential issues and can provide fixes in Cursor or through its Background Agent.
Best Use
Run it on each generated pull request before merge, then inspect the flagged logic in the surrounding code. This is especially useful when the code compiles but may mishandle edge cases or control flow.
Cost And Terms To Check
Cursor states that all plans include a 14-day free trial. The supplied evidence does not establish plan prices, supported repositories beyond GitHub, language coverage, or data-retention terms, so check the vendor page before rollout.

2. Distik
Why It Fits AI-Generated Pull Requests
Distik is explicitly positioned as AI code review for AI-generated pull requests. It looks for the small portion that breaks after polished diffs hide edge-case failures, swallowed errors, or missing context. Each pull request receives one LOW, MED, or HIGH signal, with reasons inline.
How Its Review Is Presented
Distik groups findings into ranked, risk-tagged chapters and posts them as one check instead of many inline comments. Chapter risk rolls up into a merge-confidence call, so reviewers can open the chapters driving the result and see what to verify before shipping.
What Is Not Established
The supplied evidence does not state price, free tier, languages, source-control platforms, hosting location, or licensing. Confirm those details with Distik before adopting it for a repository.
Rank #2
3. Horusec
Why It Fits Generated Code Security
Horusec is an open-source static analysis tool for identifying security flaws during development. It can search project files and Git history for key leaks and security flaws, which is useful when an AI-generated change copies a secret, weak pattern, or risky dependency configuration into a branch.

Pick the symptom - the matching free tool is one click away.
Supported Stack And Workflow
Its stated analysis languages and formats are C#, Java, Kotlin, Python, Ruby, Golang, Terraform, JavaScript, TypeScript, Kubernetes, PHP, C, HTML, JSON, Dart, Elixir, Shell, and Nginx. Developers can use the CLI, while DevSecOps teams can run it in CI/CD.
Setup And License Note
Horusec is licensed under Apache-2.0. Docker must be installed to run Horusec with all the tools it uses. The evidence does not establish a hosted service, pricing, or privacy terms; check the project and your deployment requirements before sending code to any external system.
4. KloudSec IaC Security
Why It Fits AI-Written Infrastructure
KloudSec scans Terraform and CloudFormation on every pull request. That targets a common AI-code risk: infrastructure that looks valid but exposes a security group or storage resource. Its stated checks include IAM policy and permission review, encryption, and public-access checks.
Pull-Request Fixes
Install the KloudSec GitHub App once, and results appear as a GitHub check run on pull requests that touch Terraform or CloudFormation. Each finding includes an AI-generated fix in the same language as the code, such as a corrected Terraform block or CloudFormation snippet for review.

The vendor states a 14-day free trial with no credit card and five-minute setup. The supplied evidence covers Terraform and CloudFormation only; verify support for other IaC formats, repository hosts, pricing after the trial, and data-handling terms.
Rank #4
5. Find Security Bugs
Why It Fits AI-Generated Java
Find Security Bugs is a SpotBugs plugin for security audits of Java web applications. It can detect 144 vulnerability types with more than 826 unique API signatures, giving Java teams a focused check after an assistant generates servlet, controller, authentication, or database code.
Ways To Run It
Plugins are available for Eclipse, IntelliJ / Android Studio, and NetBeans. Command-line integration is available with Ant and Maven, so you can inspect generated changes in an IDE or add the scan to a build process.
License And Boundaries
The project is open source and licensed under LGPL. Its verified scope is Java web applications; the evidence does not establish support for other languages, pull-request providers, pricing, or hosted scanning.

Why It Fits AI-Generated C And C++
Cppcheck is a static analysis tool for C and C++ that detects bugs and is rated for finding undefined behavior and dangerous coding constructs. It is a practical second pass when generated native code compiles but may contain memory, lifetime, or portability mistakes.
Standards And Deployment
Cppcheck covers C++11, C++14, C++17, and partly C++20. It supports security standards including CWE, CERT C 2016, and CERT C++ 2016. It is cross-platform, with installation packages for Windows, Linux, Mac, and BSD, and can run on-premises or air-gapped.
Pricing Note
The supplied evidence says to contact sales for a quote. It does not establish a free tier, supported CI providers, or code-retention terms, so confirm those details before choosing it for generated code review.
How To Choose A Stack For AI-Generated Code
- Start with the change location: choose Cursor Bugbot or Distik for pull-request review, KloudSec for Terraform or CloudFormation, and language-specific scanners for application code.
- Match the scanner to the generated language. Horusec covers the broadest stated set; Find Security Bugs is for Java web applications; Cppcheck is for C and C++.
- Run the review before merge and require a human to inspect each high-risk finding and proposed fix.
- Check deployment terms before uploading proprietary code. The supplied evidence gives Apache-2.0 for Horusec, LGPL for Find Security Bugs, and on-premises or air-gapped support for Cppcheck, but does not establish privacy terms for every product.
What These Tools Do Not Prove
None of the supplied evidence says that a scanner can identify whether code was written by a particular AI model. These tools check behavior, patterns, vulnerabilities, or infrastructure configuration. Treat a clean result as one review signal, then run your normal tests and inspect authorization, secrets, error handling, and business rules.
