How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Cline (Per Usage) — Cline bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Datadog (Per Usage) — Datadog bills purely on usage — host. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Open-source autonomous coding agent that runs in VS Code as an extension. Cline itself is free — users bring their own LLM API key (Anthropic, OpenAI, Google, Groq, OpenRouter, local models via Ollama). Cost is entirely determined by underlying LLM token usage. Popular with developers who want an agent-first coding experience but prefer to pay direct LLM costs rather than a marked-up subscription.
The dominant cloud observability platform (metrics, logs, traces, APM), publicly traded (DDOG), ~$45B market cap. Positioned as the alternative to New Relic + Splunk + PagerDuty stitched together. Distinctive for its notorious usage-based pricing that has surprised engineering teams with 6-figure monthly bills (Coinbase's leaked contract was ~$65M/year in 2022). Priced by seat + host + volume across 20+ meters. Popular with engineering teams; feared by finance teams.

What each is best for
Cline is worth it if… developers who already have LLM API access and want an autonomous coding agent without a subscription markup. The BYOK model is the differentiator — typical monthly cost is $5-50 in Claude Sonnet tokens depending on usage, which beats most $20-60/mo subscription tools if you're a light user.
Datadog is worth it if… infrastructure teams (10+ engineers) that need APM + logs + metrics + synthetics + RUM in one platform — the observability default at mid-market and enterprise scale. Infrastructure covers hosts; APM, Logs, RUM, Synthetics, Database Monitoring each priced separately per module.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
