Scouting report

Niche Amazfit/Zepp OS keyboard author with real star traction

assessed from open-source footprint

Senior
43signal

Stands out for shipping genuinely useful niche tooling: custom alphabetic and numeric keyboards for Amazfit Band 7 and GTS 3/4 smartwatches on Zepp OS, which together account for 17 stars and a top repo at 10 — by far the most organic traction in this batch. That hardware-adjacent JavaScript work shows initiative and a real user audience. The caveats are honest: no commits in the past year and a high abandonment ratio suggest the projects are parked, and there are no verified external open-source contributions. Strong evidence of building things people actually use, less evidence of ongoing momentum.
