Why people look for Datadog alternatives
Datadog is used by scale-ups and enterprises running complex cloud infrastructure, and it is known for putting metrics, logs, traces, security and synthetics in one platform. Entry pricing starts around $18 per host per month, but bills grow with hosts, log volume and custom metrics, and many teams only notice after the invoice arrives.
The other common complaint is lock-in: once dashboards, monitors and agents span many Datadog products, moving is hard. When picking a replacement, weigh the pricing unit (host, user or data volume), whether open standards like OpenTelemetry keep you portable, and which parts of Datadog you really use.
- Expensive and complex pricing
- Costs grow with hosts and log volume
- Easy to overspend on custom metrics
- Lock-in across many products
- Datadog starts at $18/mo (Freemium).

10 Datadog alternatives compared
- 1
Grafana Cloud
Open-source observability dashboards
Why pick it over Datadog: Grafana Cloud is built on open-source projects you can also run yourself, so you are not locked into one vendor's agents and formats as with Datadog. The Pro plan starts at $19, close to Datadog's entry price, and usage is billed by data rather than per host.
- 2
Dynatrace
AI-driven observability and app security for large cloud estates
Why pick it over Datadog: Dynatrace suits large hybrid or Kubernetes estates that want automatic instrumentation and AI root-cause analysis instead of building monitors by hand in Datadog. It is quote-based and aimed at enterprises, so it rarely saves money for small teams.
- 3
New Relic
Full-stack observability with a free 100 GB tier
Why pick it over Datadog: New Relic includes 100 GB of free data ingest each month and charges mainly by users and data, not by hosts. For teams whose Datadog bill grows with every new server, that model can be easier to predict, with paid plans from $10.
- 4
Overmind
Open-source loop that turns AI agent traces into models you own
Best for: Engineering teams with agents in production that want to improve accuracy and cost and keep ownership of the models.
- 5
CloudKnife
Azure FinOps tool that finds waste and applies approved fixes
Best for: Azure-centric companies, especially in Europe, that want cost recommendations with evidence and help executing them.
- 6
PagerDuty
On-call scheduling, alerting and incident response for ops teams
Why pick it over Datadog: PagerDuty does not replace Datadog's monitoring; it handles on-call schedules, escalations and incident response on top of whatever tools raise alerts. Pick it from $25 if paging is the weak spot and you want it independent of your monitoring vendor.
- 7
Polylane
AI on-call engineer that investigates and fixes production issues
Best for: Small platform and backend teams running on Cloudflare, Vercel or AWS who want an AI first responder without hiring an SRE.
- 8
telemetry.dev
OpenTelemetry-based tracing, cost tracking and evals for AI agents
Best for: Small teams building AI agents who want affordable tracing, cost tracking, prompt management and evals in one OpenTelemetry-based tool.
- 9
Tessary
Open-source monitoring that finds why production AI agents fail
Best for: Engineering teams running AI agents in production with OpenTelemetry traces who want every trace checked and failures explained.
- 10
Navige
Proxy that cuts AI agent model costs and stops runaway spending
Best for: Teams running production AI agents with meaningful monthly model spend who want savings without rewriting their agents.
