DataBuff vs SigNoz

Same-host lab on 192.168.50.140: DataBuff v0.1.4 vs SigNoz v0.133.0, same Demo (service-a / service-b). DataBuff uses OTLP :4318; SigNoz uses OTLP :24318. Marks: ✅ verified in this lab · △ present but limited · ❌ no equivalent.

1. Capability matrix

Seven AI capabilities (v0.1.4: See → Squad → Inspect → Diagnose → Repair → Predict → Answer)

Capability	SigNoz v0.133.0	DataBuff v0.1.4
① See · natural-language questions	❌	✅ Ask about services / topology / trends; AI reads telemetry
② Squad · multi-agent collaboration	❌	✅ Parallel evidence gathering; reusable task orchestration
③ Inspect · service inspection + report	❌	✅ One-shot inspection with evidence and actions
④ Diagnose · bottleneck / RCA evidence	❌	✅ Trace / metrics / topology evidence
⑤ Repair · Ops Expert actions	❌	✅ Repair under policy + human approval
⑥ Predict · capacity / trends	❌	✅ Capacity and trend analysis
⑦ Answer · product Q&A	❌	✅ Answers deploy / ingest / config from docs and code
Extend · MCP / Skill / custom experts	❌	✅ External MCP / Skill and custom digital experts

Largest gap: SigNoz home is Traces / Metrics / Logs Explorer — no AI platform.

APM

When to pick which

Scenario	Better fit	Note
Same OTel data, want AI / APM pages first	DataBuff (side-by-side)	Point OTLP at DataBuff
Need the seven AI capabilities	DataBuff	No SigNoz AI platform
MCP / Skill / custom experts	DataBuff	No such layer in SigNoz
See who slows the entry response	DataBuff	Service flow
Call analysis → Trace	DataBuff	No SigNoz path
Slow SQL / cache / MQ pages	DataBuff	SigNoz mostly map nodes
Custom dashboards / PromQL boards	SigNoz	DataBuff not yet
Mature Trace / Logs Explorer only	Either / lean SigNoz	No need to migrate for brand

Boundary: Deep SigNoz Dashboard / PromQL workflows → stay on SigNoz. DataBuff fits same OTel data + AI + APM depth, side-by-side or gradual switch.
