Simple edge server / reverse proxy
umputun/reproxy 的健康指数为 100 分中的 81 分,处于「优秀」区间。 其得分最高的类别是Engineering Quality(90/100),最低的是Security(44/100)。 最近一次更新在 16 天前。 近期的大部分工作由 1 位贡献者完成。
指标归入加权类别,统一采用 1–100 量表。总体分先取类别加权平均,再依据公开记录的分布进行校准,使各等级具有百分位含义;当公开证据触发高风险司法辖区政策时,评级会按政策调整,并设置 34(存在风险)的上限。
每条轴代表一个类别。形状比平均值更重要——健康的对象会填满整个图形,而“一峰一谷”式画像意味着某一维度的优势正掩盖另一维度的风险。
加权总体分 69 经校准后在公布的指数量表上为 81(记录校准 2026-08-02)。

每颗 star 和每个 fork 的添加时间,来自 GitHub 并按天汇总。累计增长位于其构成来源——每日新增——的正上方,二者可相互对照:稳定的自然增长与短暂的突增形态截然不同。当这一差别可被衡量时,它会作为增长真实性予以报告。
每个点涵盖 5 天。
来自开源项目 OpenSSF Scorecard 的独立、工具无关的安全评估。每项检查奖励的是安全实践本身,而非特定供应商的工具。Scorecard 无法判定的检查项标记为 不适用,并从安全评分中剔除(绝不按零分计)。

该仓库未发布可被索引解析的包,因此评估的是其自身的依赖图——共 83 个包,其中也包含从不交付的开发与测试版本固定:3 个存在已知公告,1 个为直接依赖。
| 软件包 | 版本 | 关系 | 严重程度 | 公告数 | 修复版本 |
|---|---|---|---|---|---|
| golang.org/x/crypto | v0.51.0 | 直接 | 严重 | 27 | 0.52.0 |

| golang.org/x/text | v0.37.0 | 间接 | 未知 | 1 | 0.39.0 |
公告表示依赖图中记录的版本落入某条公告的受影响范围。可达性未经分析,且依赖图包含开发与测试的版本固定——某项发现可能只涉及工具链而非交付的软件。
