sitespeedio / throttle
Throttle your network connection [Linux/Mac OS X]
sitespeedio/throttle holds a health index of 69 out of 100, placing it in the Good band. It scores highest on Engineering Quality (74/100) and lowest on AI Readiness (38/100). It was last updated 3 days ago. A single contributor accounts for most of its recent work.
69
overall / 100Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean, calibrated against the distribution of the public record so bands carry percentile meaning; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At Risk ceiling of 34.
69
Exceptional93-100The record's top tier (≈ top 5%); essentially all checked criteria met
Excellent80-92Strong across the board; minor gaps
Good65-79Healthy; gaps are limited and manageable
Moderate50-64Acceptable with notable gaps; review recommended
Weak35-49Material weaknesses across several areas
At Risk20-34Significant weaknesses; adoption warrants caution
Critical1-19Severe 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.
The weighted overall 62 is calibrated to 69 on the published index scale (record calibration 2026-08-02).
