I built a client-side GitHub repo comparator
Client-side avoids token leakage; star graphing is table stakes, caching is nice.

No-token GitHub star charts are nice, but Star History already does this.

To make this completely frictionless, I built Startrail. It’s a simple visualizer that handles the API fetching under the hood, so you can just drop in some repos and get the data instantly.
A few quick features: - Zero setup: No API keys, no logins, and no rate-limit warnings. - Side-by-side comparison: You can plot up to 12 repositories on the same chart. - Clean and accessible: Work smoothly on mobile for quick checks on the go.
I originally built it for my own quick benchmarks, but I’m actively tinkering with it this weekend. I’d love to hear what the HN community thinks. What context would make this even more useful for you—forks, release version markers, or something else?
Feel free to take it for a spin!

Wordle for GitHub stars, but the novelty wears off after a few rounds.

Yet another feed aggregator, but HN + GitHub combo is actually useful.
