THE MODERN MACHINE DATA PLATFORM
Axiom vs Datadog
Datadog is the broadest full-stack observability suite on the market: APM, RUM, synthetics, security, and 900+ integrations in one place. Axiom is the modern machine data platform for teams whose logs and events have outgrown Datadog’s indexing economics: keep every byte, query all of it, and pay on one predictable dial.
OVERVIEW
What’s the difference between Axiom and Datadog?
Datadog is a full-stack observability platform priced across many SKUs: you pay to ingest logs, then pay again to index them, per retention tier. Axiom is a modern machine data platform with one usage-based model: everything you load is queryable in APL on day one, with no separate indexing SKU and no overage tier.
FEATURE-BY-FEATURE COMPARISON
Axiom vs Datadog at a glance
One usage-based dial: load 0.12 to 0.06 cr/GB + query 0.20 to 0.08 cr/GB-hr + storage $0.030/GB, $25/mo platform fee
Ingestion ≈ $0.10/GB, then Standard Indexing ≈ $1.70 per M events at 15-day retention (annual)
Yes, everything loaded is queryable in APL immediately
Only indexed logs reach Log Explorer; unindexed = Live Tail only
One tier, all queryable
Flex Logs: lower-cost storage (≈ $0.05 per M events) but no monitors / Watchdog
Compute + storage + platform fee; auto volume discounts; no overage tier
30+ SKUs; overages a common surprise
Keep every field, configurable retention, 95% compression
Retention priced in tiers; teams sample or shorten to cope
APL: piped, sequential
Faceted log search (dashboard-oriented)
OTel-native incl. OTel Metrics GA: logs + metrics on one dial
Supports OTel; core value is the agent + integrations
Logs, events, traces, metrics on one event store
Full-stack: APM, RUM, synthetics, security, 900+ integrations

KEY QUESTIONS, ANSWERED
Common questions
PRICING AND INDEXING
For log-heavy workloads, usually, and always more predictable, because you’re not paying to index separately. You pay once on a single dial (load, query, store), with volume discounts and no overage tier.
No. There’s no indexing step: everything you load is searchable in APL, so no field is stuck in Live Tail during an incident.
QUERYING AND AI
Yes, APL, but it’s built for the ad-hoc, pipeline-style analysis Datadog’s faceted search isn’t.
Yes, a native MCP server lets agents see every loaded byte in APL, with no indexing SKU limiting scope.
PLATFORM COVERAGE
For OpenTelemetry metrics, yes: OTel Metrics GA moves logs and metrics onto one dial. (APL spans logs, events, and traces; metrics use MPL.)
Breadth: APM, RUM, synthetics, database monitoring, security, 900+ integrations, and Watchdog. If one-vendor consolidation is the priority, Datadog is strong.
IS AXIOM RIGHT FOR YOU?
Which one is right for you?
Choose Axiom if…
- Logs and events are what’s breaking the Datadog bill
- Indexing selectively or shortening retention to cope
- Want one predictable usage-based dial
- Standardizing on OpenTelemetry (logs + metrics)
- Want every byte queryable by engineers and agents
Choose Datadog if…
- Want one vendor for the entire stack
- Depend on APM / RUM / synthetics / security breadth
- Rely on the 900+ integration catalog
- Value turnkey setup and mature dashboards
MIGRATION
Moving log workloads off Datadog
Point your OpenTelemetry Collector (or Vector, Cribl) at Axiom, start with your highest-volume log source, and query it in APL, no indexing decisions. Keep Datadog for APM while the economics prove out.
