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.
- OpenObserve (Per Usage) — OpenObserve bills purely on usage — $0.50/GB ingest + $0.01/GB query (30% off annual, no per-seat fees). There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Tabnine (Per Seat) — Tabnine bills on a fixed plan from $39/mo, 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.

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.

What each is best for
OpenObserve is worth it if… OpenObserve is ideal for teams migrating off Datadog, Splunk, or New Relic who want radically transparent pay-per-GB pricing with no seat fees. Best if your telemetry cost is dominated by log and metric volume rather than user count.
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 — OpenObserve is per usage, Tabnine is per seat.
