What Actually Matters

SigNoz lets you self-host with Docker — your data, your rules. Warden? Cloud only. If privacy matters, that's a dealbreaker.
SigNoz dominates with 32.4k GitHub stars vs 5. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
SigNoz is built in TypeScript, Warden in Go. Matters if you want to contribute, extend, or debug internals.
