Our take
Pick OpenObserve if platform / SRE teams who will self-host OSS at $0, stay on Self-Hosted Enterprise free through 50 GB/day, or start the 14-day Cloud trial and land on $0.50/GB ingest + $0.01/GB query when they want logs without a per-host Datadog card. Pick SigNoz if platform teams who will stay on Community Edition $0 (self-host, no card) while they ship a first OTel pipeline, then buy Cloud Teams at $49/month
