For teams that write code, not for teams that buy platforms.
Datadog is an observability platform with a sales motion attached. Bugtail is a tool: four things, a published price, and a cancel button on a screen rather than at the end of a contract.
Priced on what you send, not on what you run
Per-host pricing punishes exactly the thing you want people to do: split a monolith, add a worker, scale out for an afternoon. Here errors are unlimited, the bill follows the storage, the log lines, the spans and the readings you actually use, and the numbers are on the pricing page rather than in a quote.
There is no agent to install on every host, which removes a whole category of cost and a whole category of incident. Your application reports over HTTP, from wherever it happens to be running.
What you give up, honestly
Infrastructure monitoring, synthetics, RUM, network device monitoring, security monitoring, a hundred and fifty integrations and a dashboard builder. Datadog covers an enormous surface and does most of it well. If your job is running infrastructure rather than shipping an application, this is not the tool.
What is left is the part most application teams actually open every day: what broke, what it said, how often, and where the time went.
Side by side
| What | Bugtail | Datadog |
|---|---|---|
| Priced on | Events, log lines, spans, readings | Hosts, plus ingested and indexed volume |
| Agent on each host | None | Yes |
| Company jurisdiction | Belgium | United States |
| Buy without talking to sales | Yes, every plan below Enterprise | Small plans yes, in practice usually no |
| Infrastructure monitoring | No | Yes |
| Errors, logs, traces, metrics | Yes | Yes |
| Your own storage bucket | Yes | No |
Written against Datadogs published list pricing and product pages. It is a far larger product; this compares only the overlap.
Questions people actually ask
We already run Datadog for infrastructure. Does this replace it?
No, and it is not trying to. Plenty of teams keep infrastructure monitoring where it is and move the application-level part here, which is the part with personal data in it and the part developers open every day.
Can we send the same OpenTelemetry data to both?
Yes. Configure a second exporter, or fan out from your collector. Running two backends in parallel is the cheapest way to compare them.

Sign up with your work address, prove your domain with one DNS record, and paste a DSN. The first stack trace usually arrives before the coffee does.
No card. The trial ends by itself and drops to Free; nothing is charged unless you choose a plan.
