I often find myself wanting to quickly compare the adoption curves of different open-source projects, but I usually bounce when a tool asks me to generate and paste a GitHub personal access token just to view a chart.

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!
