Keep Datadog for APM. You don't need a platform for counters.
Datadog is a superb observability suite. If what you actually need is simple product and business metrics — signups, jobs run, revenue events, queue depth — EzStat does exactly that: one HTTP POST, a live chart, flat pricing by tracked stats.
No per-host. No per-seat. No per-GB. No cardinality math. $19/mo, $49/mo and $99/mo all track 10,000 stats — differentiation is monthly datapoint volume and retention (30 days, 1 year, 3 years), not the stat cap. The number on the pricing page is the number on the invoice.
The integration you can finish before lunch
curl -X POST https://api.ezstat.dev/ez \ -d "stat=signups" -d "ezkey=YOUR_KEY" -d "count=1"
No collector daemon, no SDK, no YAML. Stats auto-create on the first POST. Ask questions in plain English with Ask-Your-Data — answers are computed from your real data and verified before you see them.
What we won't pretend
EzStat is not an APM, log pipeline, or tracing suite — Datadog genuinely does more. Your data exports to CSV/JSON any time; billing is monthly; cancel whenever.
