cloudwego / kitex
Go RPC framework with high-performance and strong-extensibility for building micro-services.
cloudwego/kitex holds a health index of 96 out of 100, placing it in the Exceptional band. It scores highest on Community & Adoption (94/100) and lowest on AI Readiness (61/100). It was last updated today. 6 contributors account for most of its recent work.
96
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.
96
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 83 is calibrated to 96 on the published index scale (record calibration 2026-08-02).

| unassessed_packages | 0 |
| affected_by_severity | high 1, moderate 1, unknown 2 |
| direct_affected_packages | 2 |
Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 45 resolved dependencies against OSV. This repository publishes no package the index resolves, so the repository dependency graph was assessed instead. That graph mixes development and test pins with shipped dependencies, so only the declared runtime dependencies are scored; transitive findings are reported as context and excluded from the score. Reachability is not analyzed.
AI Readiness
How well is the repo equipped to be developed and maintained with AI coding agents? Carries a deliberately small weight (4%): agent tooling is a real maintenance signal, but a repository with none can still reach 100/100.

When each star and fork was added, collected from GitHub and bucketed by day. Cumulative growth sits directly above the daily additions it is made of, so the two read against each other: steady organic accretion looks nothing like an abrupt, short-lived burst. Where that difference is measurable, it is reported as growth authenticity.

Dependency advisories 4
This repository publishes no package the index resolves, so its own dependency graph was assessed — 45 packages, which also include development and test pins that never ship: 4 carry known advisories, of which 2 are direct.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| github.com/apache/thrift | 0.13.0 | indirect | high | 1 | 0.23.0 |
| golang.org/x/net | v0.24.0 | direct | moderate | 16 | 1.27.0-rc.3 |
| golang.org/x/sys | v0.30.0 | direct | unknown | 1 | 0.44.0 |
| golang.org/x/text | v0.14.0 | indirect | unknown | 1 | 0.39.0 |
An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.

Spotted something off in this report, or have thoughts to share? Wrong measurements, missed tooling, ideas, questions — anything is welcome. Every message is read and gets a response.
Scores are signals, not warranties. They reflect publicly visible practices on GitHub — not a code audit, and not a security guarantee.
Missing data is excluded and weights renormalized, never scored as zero. Methodology is versioned and open: metrics v2.10.0, schema v0.34.0 — full methodology · metrics wiki.
