Developers often find it challenging to review complex changes in large codebases using text-based diff tools.
Build a visual diff tool that integrates with git, providing an intuitive interface for reviewing changes and identifying conflicts.
Developers and code reviewers would pay for this tool to improve their productivity and code quality.
Start with a basic visual diff interface for git repositories, then add more advanced features like side-by-side comparison and conflict resolution.
The biggest risk is competition from existing diff tools and integration challenges with different git workflows.
