neuecc / Utf8Json

Definitely Fastest and Zero Allocation JSON Serializer for C#(NET, .NET Core, Unity, Xamarin).

C#MIT★ 2,384 stars⑂ 269 forkssince Sep 2017archivedView on GitHub ↗

neuecc/Utf8Json holds a health index of 14 out of 100, placing it in the Critical band. It scores highest on Community & Adoption (68/100) and lowest on Security (22/100). The repository is archived, so no further maintenance is expected.

overall / 100

Critical

Software 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.

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 40 is calibrated to 35 on the published index scale (record calibration 2026-08-02).

Abandonment alert

Work has arrived and nobody has attended to it

archived on GitHub by its maintainersOverall rating: Critical ceiling

Silence alone is never the finding — a small, finished library may need no commits for years. This alert requires both: no human commit for a long time, and obligations the project is visibly not discharging. Automated commits do not count as maintenance.

Inputs used

Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 102 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

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.

Dependency advisories 3

This repository publishes no package the index resolves, so its own dependency graph was assessed — 102 packages, which also include development and test pins that never ship: 3 carry known advisories, of which 2 are direct.

Package	Version	Relation	Severity	Advisories	Fixed in
MessagePack	`1.6.1.2`	direct	high	13	`3.1.7`
Newtonsoft.Json	`10.0.3`	direct	high	1	`13.0.1`
System.Net.Http	`4.1.0`	indirect	high	1	`4.3.4`

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.
