Developers waste time cloning and evaluating GitHub repos that turn out to be poorly maintained. Build a tool that scores repos based on code quality, maintenance activity, and other factors.
Target developers who frequently use GitHub for work or personal projects. Offer a free version with basic scoring and paid tiers for advanced metrics.
Start with basic scoring metrics like commit frequency and issue resolution time. Later add more sophisticated code quality analysis.
The risk is GitHub adding similar features to their platform.
