What is it?

Daily Stars Explorer lets you look up any public GitHub repository and see its complete star history as a daily chart. Beyond stars, it shows activity timelines for commits, pull requests, issues, forks and contributors, so you can check what a project was doing when its star count jumped.

The tool can also overlay feed mentions from Hacker News, Reddit, YouTube and GitHub to show when a repo was discussed, compare two repositories side by side, and apply moving averages or smoothing to turn noisy daily counts into a trend. Results can be exported as CSV or JSON, and fetched data is cached for seven days.

Star history is built from GitHub's star history endpoint, so charts work without a personal access token. Other timelines still require a PAT. Hourly star resolution is no longer available, since GitHub stopped exposing per-stargazer timestamps. The project is written in Go with a JavaScript frontend and can be run locally or self-hosted via Docker.
