cubic
cubic is an AI-powered code review platform that automatically analyzes pull requests in GitHub to help software teams catch bugs, enforce standards, and ship code faster by reducing manual review bottlenecks. It delivers context-aware feedback seconds after a PR is opened by examining the full repository history and patterns, surfacing inline comments that highlight bugs, anti-patterns, technical debt, and improvement suggestions that human reviewers might miss, and providing one-click fix options for simple issues. cubic can generate clear PR summaries that explain the intent and impact of changes, intelligently order complex diffs into easier-to-review chunks, and offer a context-aware chat interface that lets developers ask questions or explore the codebase directly within the platform. Teams can define custom review rules and integrate business context from issue trackers like Jira, Linear, or Asana so that code reviews validate acceptance criteria as well as technical quality.

Gitbox
One-click commit, push and pull. Unique search in history and undo for Git commands. Powerful commands like rebase, branch reset and cherry picking. And now it works with submodules. Gitbox integrates with popular diff tools such as Xcode FileMerge, Kaleidoscope, Changes, DiffMerge. Use keyboard for ultimate efficiency. Use arrow keys to jump between all the panes and lists. To stage all files, hit Cmd+Shift+Return. To stage/unstage selected files, use "S" shortcut. To pull and push, use "U" and "P" shortcuts. Press Option key to perform fetch. Press Cmd+Shift to force push or rebase. Right click menus contain all the advanced features you might need. For instance, to reset a branch, cherry pick a commit or revert a file. To amend a commit, simply undo it (cmd+Z). You can also undo merge, pull and even push. To find a bug, use color labels. Check out a commit, test it and mark if it works or not. This is a much better and visual approach than git-bisect.
