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.
- Datadog (Per Usage) — Datadog bills on usage — host on top of a paid plan starting at $18/mo. The plan includes an allowance; anything beyond it is metered.
- Tabnine (Per Seat) — Tabnine bills on a fixed plan, so the listed price is what you pay regardless of volume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
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.
AI code completion tool with a security/enterprise focus — offers a fully self-hosted/on-prem deployment where no code ever leaves the customer's infrastructure. Pricing: Dev $9/user/mo (annual, cloud), Enterprise $39/user/mo (SSO, admin controls, on-prem option), Enterprise-plus custom. Popular with regulated industries (finance, healthcare, defense) that can't use cloud AI coding tools.

What each is best for
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.
Tabnine is worth it if… regulated enterprises (banks, hospitals, defense) that need AI code completion but cannot ship code to a cloud LLM. Dev tier at $9/user/mo is competitive but the strategic sale is Enterprise at $39/user/mo where the on-prem model runs entirely inside customer infrastructure.
Bottom line: Choose based on how you want to pay — Datadog is per usage, Tabnine is per seat.
