agenterr vs datadog
Error tracking without the platform bill.
Datadog is an observability platform priced for companies with a platform budget. Agenterr does one slice of it — errors and logs, grouped into issues — for indie devs and the coding agents working with them.
The scope difference
Datadog covers metrics, traces, dashboards, security, and more. Agenterr tracks errors and logs, groups them into issues, and stops there. If you need one thing done in 25MB of RAM rather than a platform, that trade is the point.
The pricing difference
Datadog bills per host plus per GB of ingested logs, so costs climb with your traffic. Self-hosting agenterr is free and unlimited under AGPL-3.0, whatever your volume. A hosted option is coming later at a flat monthly price, never metered by gigabyte.
The ownership difference
Datadog is SaaS only. Agenterr is open source: run it on your own server with your data in one file you can copy, back up, or take with you — including out of our hosted version.
When Datadog is the right choice
Infrastructure fleets, APM across services, compliance dashboards, an ops team that lives in it. Datadog is a platform. Agenterr trades platform breadth for weight, price, and agent access.
