Pricing
Datadog DBMを50データベースで集計。これが請求書だ。
2026年に50 Postgres + 12 MySQL + 8 MongoがDatadog DBMで実際にいくらかかるかを行ごとに分解、ツール変更なしで削減する方法も。
Datadog DBM is genuinely a very good product. It’s also famous, in 2026, for the price tag at scale. We added it up for a hypothetical mid-market SaaS — 50 Postgres + 12 MySQL + 8 Mongo databases across 30 hosts — using public list pricing.
The line items
Hosts (30 × $23/host/mo · APM/Infra) = $690 / mo
DBM hosts (30 × $70/host/mo) = $2,100 / mo
DBM database instances (70 × $35/inst/mo) = $2,450 / mo
Log management (estimated, 50GB/mo) = $250 / mo
----------
$5,490 / mo ($65,880 / yr)That’s before custom metrics overage, before retention upgrades, and before any of the SaaS-only features your CISO doesn’t love. In practice the bill is 30–80% higher than the line items above.
What you can do without switching tools
- Drop DBM hosts that don’t actually run a DB process.
- Tag “dev” instances and exclude from DBM scope.
- Negotiate the per-instance fee at renewal — it’s the most negotiable line.
- Don’t pay for log retention longer than 7 days for DB logs.
- Move collection off Datadog APM to your own pipeline — DBM’s value is the agent + UI, not the storage.
What you can do by switching tools
Obsfly comes in at roughly 1/3 of that bill on the same fleet, with BYOC available for the regulated workloads, and AI features that aren’t generic-purpose Bits. Full comparison: /datadog-dbm-alternative.
