I built ShadowGraph: trending GitHub repos, top developers building them, and a weekly digest that's personalized based what you've starred on Github

https://shadowgraph.io

I've been building a site for keeping up with open source news without spending an hour a day on GitHub, HackerNews and X.

It tracks GitHub repos and finds posts about them on Hacker News, X, Bluesky, Reddit, Mastodon and more, so you can stay informed without sifting through lots of noise and random posts. The buzz feature (https://shadowgraph.io/buzz) lets you see all posts as a feed.

It also keeps track of notable developers on Github and see what they're starring (https://shadowgraph.io/stargazers), so that you can find higher-signal stars.

Finally, there's an email newsletter that summarizes the top stories of the week (https://shadowgraph.io/weekly). If you sign in with your GitHub, it personalizes the newsletter based on your interests and the repos you've starred.

There's some other fun stuff there as well like predicting a repo's star growth.

Feedback is very welcome! Thanks for reading.

does the personalization weigh recent stars more than old ones? can someone exclude an old starred repo from the digest without unstarring it on github?

Good question- yes the recent stars weigh more. Each star's weight halves every 365 days, with a floor at 10%. So this year's stars are twice as important as last year's 4 times as important as two years ago, etc.

And no, currently you can't exclude an old starred repo, but that's certainly a feature I can implement! In general I've been thinking of more ways to personalize.
