harperfast / harper
Harper is an open-source Node.js performance platform that unifies database, cache, application, and messaging layers into one in-memory process.
harperfast/harper holds a health index of 74 out of 100, placing it in the Good band. It scores highest on Vitality (94/100) and lowest on Security (59/100). It was last updated today. A single contributor accounts for most of its recent work.
74
overall / 100Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.
74
Excellent85-100Exemplary; meets essentially all checked criteria
Good70-84Healthy; minor gaps
Moderate50-69Acceptable with notable gaps; review recommended
At risk30-49Significant weaknesses; adoption warrants caution
Critical1-29Severe problems (abandoned, single-maintainer, no hygiene)
Score profile
Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.
