DatadogCAUTIOUS-BUY
The default observability platform — and the cost of default

Datadog owns enterprise observability. APM, logs, metrics, RUM, security all work. The pricing is genuinely brutal at scale, and the alternatives (Grafana Cloud, Honeycomb, Coroot) have gotten serious enough to evaluate.

LiveKitBUY
The infrastructure layer for serious voice AI

LiveKit owns the real-time audio/video stack for AI voice agents — OpenAI's Realtime API runs on it, ChatGPT Voice runs on it. If you're building voice AI, this is the substrate you build on.

Choose Datadog if...

Enterprises that want a single pane of glass across infra, apps, and security and can budget for the bill.

Avoid Datadog if...

Cost-sensitive startups — observability bills balloon quickly; Grafana Cloud or self-hosted Prometheus + Loki often fit better.

Choose LiveKit if...

Building AI voice agents, real-time multiplayer apps, video conferencing features. The default choice for serious AI voice.

Avoid LiveKit if...

Simple async voice calls — Twilio is fine. Pure transcription workflows — go straight to Deepgram or AssemblyAI.

Both suited for: small, medium, large, enterprise companies
