Choose SigNoz.
If you want to own your data, save money, and avoid vendor lock-in, SigNoz is open source and community-driven.
What Actually Matters
No fluff — just the differences that affect your decision
SigNoz is open source (MIT). Datadog is closed. If vendor lock-in keeps you up at night, this is the deciding factor.
SigNoz supports self-hosting via Docker. Datadog is SaaS-only — convenient, but you're renting, not owning.
SigNoz has the bigger crowd: 32.4k stars vs 0. More contributors, more integrations, more momentum.
SigNoz is built in TypeScript — you can read the source, contribute, or fork it. Datadog is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
