LambdaBytes / sping

A modern ping for humans. Terminal-native, real-time connectivity monitor that doesn't just measure packets — **it interprets network context**.
**Status:** functional and in active use, with a frozen JSON contract.
Linux, macOS and Windows; x86_64, aarch64 and armv7 (Raspberry Pi).
Answers three questions at once:
1. **Does the target respond?** — RTT, TTL, jitter, loss, quality score, trend
2. **Do I have network from this interface?** — gateway reachable, WAN reachable
3. **What type of problem is it?** — correlated diagnostics, automatic
 [code] 
## What's new in 1.7.1
- **`--diagnose`** (experimental): when the target stops answering, sping
 probes further on its own (the other address family, TCP 443 and 80, a
 bounded traceroute) and says what still answers; see
 Diagnose.
- **The name's lookups as evidence**: a lookup that fails while the WAN
 reference answers, or that gives no address of the family probed.
- **Context changes while monitoring**: `context changed 00:03 ago:
 interface eth0 → wlan0`, for the interface, source, prefix, default gateway
 and target class.
- **Fix**: an IPv6 target routed through an interface without IPv6 reads
 `no IPv6 source`, not `lo ::1/128`.
Every change, version by version: CHANGELOG.md.
## Multi-target dashboard
 [code] 
 [code] 
The table is live and needs a terminal: with stdout a file or a pipe, sping
prints only each target's summary at the end (`-c N` stops it). Batch mode
(`--batch`, below) prints per-host results or JSON.
