snowflakedb/snowflake-kafka-connector holds a health index of 73 out of 100, placing it in the Good band. It scores highest on Vitality (96/100) and lowest on Engineering Quality (49/100). It was last updated 3 days ago. 4 contributors account for most of its recent work.
73
overall / 100
Good
Software 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.
73
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.
Direct dependencies free of known advisories — no direct dependency carries a known advisory

Matched the maven:com.snowflake:snowflake-kafka-connector@4.1.0 runtime dependency closure — what installing the published package pulls in — 33 packages. Reachability is not analyzed.
How well is the repo equipped to be developed and maintained with AI coding agents? An independent, experimental badge — weight 0.0, so it is surfaced on its own and does not affect the overall health score.

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.

OpenSSF Scorecard 6.5 / 10
6.5aggregate
Independent, tool-agnostic security assessment from the open-source OpenSSF Scorecard. Each check rewards a security practice, not a specific vendor's tool. Checks Scorecard could not determine are marked n/a and excluded from the security score (never counted as zero).Scorecard v5.5.0 · 2026-07-26 09:10 UTC
Full resolved dependency set from the GitHub dependency graph: 22 direct and 32 indirect (transitive) packages. The transitive closure is complete when the repository commits a lockfile.
Installing maven:com.snowflake:snowflake-kafka-connector@4.1.0 pulls in 33 packages, direct and transitive: 1 carry known advisories, of which 0 are direct dependencies.

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.
