6 Alternatives to Datadog LLM Observability in 2026
Teams reconsider Datadog when the invoice grows one product meter at a time, when logs or spans are billed beyond what they query, or when they want OpenTelemetry-native data with a self-hosted exit. Common landings are SigNoz, groundcover and Grafana Cloud, with Better Stack for smaller teams.
Why people look for an alternative to Datadog LLM Observability
Each product is its own meter
Datadog sells Infrastructure Pro from $15 per host, APM from $31 per host, and logs from $0.10 per ingested GB, so adding tracing or logging adds a separate line to the bill.
On-demand rates and attached prerequisites
The pricing page lists on-demand Infrastructure at $18 versus $15 annual, and APM at $31 only with Infrastructure attached, or $36 standalone, which rewards commitment more than flexibility.
AI features are metered credits
Bits Chat, Investigation, Code and Agent Builder run on AI Credits starting at $500 per 500 credits per month, or $1.30 per credit on demand, which is another budget to forecast.
The best Datadog LLM Observability alternatives
- 1
SigNoz
SigNoz is an OpenTelemetry-native platform that bills one meter per signal, with a $49 monthly minimum, unlimited users and hosts, and cloud regions in the US, EU and India. A self-hosted Community edition is the fallback.
Switch if you want OpenTelemetry data, per-signal billing you can audit, and a self-hosted option to fall back on.
- 2
groundcover
groundcover's Pro plan is $30 per host monthly, counted from the average number of hosts monitored in the month instead of data volume. An eBPF sensor instruments Kubernetes, telemetry never leaves your own VPC, and Pro retains logs and traces for as long as 30 days.
Switch if you Switch if Kubernetes log volume drives your bill and you want a per-host price that ignores ingestion.
- 3
Grafana Cloud
Grafana Cloud hosts Prometheus, Loki and Tempo. The free tier offers 10k series and 50 GB of logs, and Pro is $19 monthly as a platform fee plus usage. Series and users are among the several meters, and Assistant seats are extra.
Switch if you Switch if your team already uses Prometheus or Grafana dashboards and wants a hosted version with a real free tier.
- 4
Better Stack brings logs, uptime monitors, on-call scheduling and a status page together. Its free plan holds 10 monitors and 3 GB of logs, and paid telemetry bundles start from $25 monthly on yearly billing. Responder licenses are priced separately.
Switch if you are a small engineering team that wants monitoring, paging and a status page on one invoice.
- 5
New Relic
New Relic includes 100 GB of free data every month and charges $0.40 per GB after that, plus user fees on Standard and Pro editions. SRE Agent and AIOps are listed within the same platform. The free ingest ends at 100 GB.
Switch if you want a permanent free tier and a single data price instead of per-host billing.
- 6
Dynatrace
Dynatrace charges $58 monthly for each 8 GiB host on Full-Stack, with automated root cause analysis part of that price. You can set retention anywhere from one day to ten years, and an MCP server exists. Many meters apply to pricing.
Switch if you run a large estate and value automatic root cause analysis over assembling dashboards yourself.
Before you switch away from Datadog LLM Observability
Start with your last three Datadog invoices and note which products drive them: hosts, indexed logs, APM spans or custom metrics. Count your dashboards and monitors, since those are the real migration work, and check which are built on Datadog-specific query syntax. Confirm that your services emit OpenTelemetry or can be switched over, because a vendor-neutral pipeline makes the next move cheaper. Run the candidate in parallel for two weeks on one service, compare alert timing and retention, and keep Datadog's annual commitment end date in mind.

Frequently asked questions
Is Datadog's free tier enough to keep after switching?
Datadog's free tier covers up to five Basic hosts with one-day metric retention on Infrastructure, and Feature Flags are free below 1M monthly configuration requests. That suits a hobby project, not production incident review. Grafana Cloud, Better Stack and New Relic offer free allowances with more data or longer windows.
Does Datadog train on or locate my telemetry anywhere specific?
The privacy page says the company uses collected information, including product information, to improve its products, and notes data may be stored outside your country, including the United States. A hosting region is not stated there. SigNoz offers EU region and self-hosting, and groundcover keeps data in your VPC.
How do I estimate what Datadog alternatives cost compared with it?
Rebuild your current invoice by signal: hosts, GB of logs, spans, and metrics. Per-host tools such as groundcover charge $30 per host, while SigNoz and New Relic meter data volume. Datadog's volume discounts at 500+ hosts are negotiated, so compare against your real contract rate, not the list price.
Can I keep my Datadog dashboards when I move?
Not automatically. Better Stack says it can import dashboards from Datadog and Grafana, which cuts trial effort. Elsewhere, dashboards and monitors must be rebuilt by hand or script. Teams already using OpenTelemetry skip re-instrumenting, so the dashboard layer is usually the main cost.
