## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 100, release rhythm 35, longevity 100
- inputs: {"age_days": 1750, "days_push": 0, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A continuously maintained dataset of publicly available STUN servers, validated hourly and published as plain-text lists (all hosts, IPv4, IPv6, and RFC5780-capable servers) plus a GeoIP cache. It is written in Rust and intended to be hard-coded as raw GitHub URLs in applications needing fresh STUN endpoints.

## Use cases
- find a list of working public stun servers
- get fresh stun server list for webrtc app
- hardcode a reliable stun server list url in my application
- find closest stun server by geolocation
- stun servers that support rfc5780 nat behavior testing
- ipv4 and ipv6 stun server addresses

## When to choose
- you need an automatically refreshed, verified list of online STUN servers without running your own health checks
- you want to hard-code stable raw URLs for STUN host lists in a WebRTC, VoIP, or P2P application
- you need RFC5780-capable servers for NAT behavior testing or geolocation-based nearest-server selection

## When to avoid
- you need a TURN server list or relay infrastructure rather than STUN
- you need a runnable STUN client or server implementation rather than a list of endpoints
- you require guaranteed SLA-backed availability rather than best-effort hourly checks

## Facets
- artifact type: dataset
- maturity: active
- function: networking, monitoring
- domain: networking, developer-tools, apis
- platform: cross-platform, cli
- tags: stun, nat-traversal, webrtc, server-list, voip, hourly-refresh, geolocation, web-server
