A cheaper Datadog alternative: why your observability bill explodes (and how flat pricing fixes it)
There's a meme in the DevOps world that isn't a joke: the surprise Datadog bill. The tool is excellent — but its pricing charges per host, per module and per GB, so the invoice grows with your infrastructure and explodes when you least expect it. We compared Kubmix Flux against Datadog and New Relic — and the focus here is what hurts: the pricing model.
The problem isn't the sticker price — it's the model
Datadog and New Relic charge by consumption, and that's where the bill escapes control:
| Tool | Model | Price (public) |
|---|---|---|
| Datadog — Infra | per host/mo | US$ 15/host |
| Datadog — APM | per host/mo (requires Infra) | +US$ 31/host |
| Datadog — Logs | per GB indexed | US$ 0.10/GB |
| New Relic | per GB ingested + per host | US$ 0.30/GB + US$ 19/host |
| Kubmix Flux flat price | fixed monthly plan | US$ 0 to US$ 499 |
The real math: 20 hosts with APM
Picture a modest setup: 20 hosts, with infrastructure + APM. On Datadog:
- 20 × (US$ 15 + US$ 31) = US$ 920/month just for host + APM
- + logs at US$ 0.10/GB (easily hundreds of dollars more)
On Kubmix Flux, the Professional plan is a flat US$ 187/month — no multiplying by host, no end-of-month shock. You know exactly what you'll pay.
Kubmix Flux plans
| Plan | Price/mo | For |
|---|---|---|
| Free | US$ 0 | try it, no credit card |
| Starter | US$ 79 | startups and growing teams |
| Professional | US$ 187 | teams with serious monitoring needs |
| Enterprise | US$ 499 | large-scale operations |
Full observability — infrastructure, APM, logs, metrics, uptime, session replay and heatmaps — at a predictable, flat price.
Beyond price: data residency
- Flat pricing: a predictable budget instead of a per-host meter that grows with your infra.
- Observability data in Brazil: logs and metrics (which often contain sensitive data) in a national datacenter, compliant with the LGPD.
- Portuguese-language support.
FAQ
Is there a cheaper alternative to Datadog?
Yes. Kubmix Flux is an observability platform with a flat monthly price (starting free), instead of Datadog's per-host / per-GB model that scales with your infrastructure.
Why does the Datadog bill get so expensive?
Because pricing is per host, per module (APM billed separately) and per GB of logs — everything grows with your infra. Custom metrics and extended retention inflate it further.
How much does Kubmix Flux cost?
Free (US$ 0), Starter (US$ 79/mo), Professional (US$ 187/mo) and Enterprise (US$ 499/mo) — flat plans.
Where is the monitoring data stored?
In a datacenter in Brazil, compliant with the LGPD.
Conclusion
Datadog and New Relic are great tools with a pricing-model problem: the bill grows with your operation and explodes on add-ons. Kubmix Flux swaps that for a flat, predictable price, with data hosted in Brazil. For teams that have already been burned by an observability invoice, that's the difference between budgeting and hoping.
