Cheaper Datadog alternatives: 8 tools that cut the bill

Datadog is great until the invoice lands. It charges per host, per GB of logs and per product, so the bill grows every time your app does. The tools below claim to do the same job for a lot less. Every number is the company's own claim, linked on each listing.

Why Datadog gets expensive

• Per-host pricing: every new server or container node adds to the bill.
• Logs by volume: ingest and retention are charged separately, so keeping logs longer costs more.
• Many products: APM, logs, RUM and synthetics are each priced on their own.

Full observability, for less

SigNoz says teams moving from Datadog save up to 80% on a setup with 20 APM hosts and 50 infra hosts. It's open source, so you can also host it yourself.

Middleware bills by GB ingested instead of per host. Its sample bill is $347 a month against $1,222 on Datadog.

Dash0 bills per signal, not per host, and claims bills up to 70% lower.

Kubmix Flux uses flat monthly plans from $79. Its example: 20 hosts with APM cost about $920 a month on Datadog versus $187 on its Professional plan.

Logs only

OpenObserve cites a side-by-side test where the same telemetry cost $174 a day on Datadog and $3 a day on OpenObserve.

ChaosSearch suggests keeping only three days of logs in Datadog and the rest in ChaosSearch, for savings of about 40%.

Logit.io starts at $25 a month on an annual plan.

Infrastructure and uptime

ManageEngine OpManager Nexus has fixed upfront pricing. Its example: $3,706 a year against $32,268 on Datadog Pro.

Site Qwality targets small SaaS teams: uptime checks, logs, RUM, on-call and a status page for $780 a year against $2,978 on Datadog, before host and APM charges.

How to pick

• Want everything in one place? Start with SigNoz, Middleware or Dash0.
• Logs are most of your bill? Look at OpenObserve or ChaosSearch first.
• Small team that mostly needs uptime and alerts? Site Qwality is the simplest switch.
