Local pull-request diff review
Reviews pull-request diffs against the complete local checkout, with changed-file tracking, multi-file navigation, and observations displayed beside the relevant code.
CodeCrab
CodeCrab is a native desktop app for local GitHub pull-request reviews, inline AI findings, repository-specific skills, and keeping code and review execution on your machine.
Local-first pull-request review
CodeCrab is a native desktop application for reviewing GitHub pull requests against a local repository checkout. It loads the diff locally, shows changed files and inline AI observations, and uses the repository's code, rules, and selected review skills to investigate potential correctness, security, and regression issues.
The product is designed for engineers who want local execution and control over the review process. It runs on the user's machine, does not upload source code to a vendor cloud, uses existing local AI tooling such as Claude Code, and remains read-only today: users decide which findings to act on, comment on, or fix.
Features
Repository-aware profiles
Builds a repository-specific review profile from project rules and patterns, rather than applying only a generic checklist.
Configurable review skills
Supports local skills and specialized review skills for areas including security, test completeness, and correctness; users can choose which skills to run.
Interactive findings workflow
Shows a live execution console and lets engineers investigate findings, ask follow-up questions, and inspect the reasoning in context.
Local AI tool orchestration
Uses existing local tools and subscriptions, including Claude Code and the site's mentioned Cursor workflow, while allowing users to choose their AI models and control review spending.
Local test verification and control
Runs native tests such as cargo test, pytest, or npm test before changes are applied, while keeping the workflow read-only by default.
Use cases
Team pull-request review
Review a teammate's pull request with the full checkout in context, navigate changed files, investigate inline findings, and decide which issues warrant action before merge.
Pre-push quality checks
Run a review on local changes before they become a pull request, using repository rules and a pre-push skill to catch issues earlier in the development cycle.
Clarifying feedback on your own PR
Investigate vague or unfamiliar review comments by tracing callers, tests, neighboring modules, and the surrounding GitHub conversation, then produce an editable fix prompt for a local AI tool.
Risk-focused review
Apply a deeper, targeted review skill to sensitive changes such as authentication work, while using lighter criteria for routine changes.
Pros and Cons
Pros
- Runs reviews on the local machine without uploading source code to a vendor cloud.
- Uses the full local checkout, repository-specific profiles, and selectable custom skills rather than relying only on the pull-request diff.
- Provides inline observations, a live execution console, follow-up investigation, and multi-file diff navigation.
- Works with local development context and can run native test suites such as cargo test, pytest, and npm test.
- Keeps engineers in control by avoiding commits, pushes, and public GitHub comments by default.
Cons
- The available evidence describes a free public beta and does not establish paid-plan details, usage limits, or long-term availability.
- The product is read-only today; automatic fixes, publishing review comments, and other write actions are described as future or planned workflows rather than current features.
- Setup requirements and the full list of supported platforms and integrations are not specified in the available product content.
