What you get

Everything one small team needs to run an app.

Each part works on its own. They share the same events, so a slow route, its logs and the session that hit it sit one click apart.

Logs Search, levels, patterns.

Errors Grouped, counted, trended.

Traces A waterfall for every request.

Web analytics Pageviews, sources, countries.

Funnels and journeys See where people drop off.

Sessions Every step one visitor took.

MCP for AI Ask your data in chat.

AI spend Cost per model, per day.

Alerts Thresholds to Slack or email.

Exports Nightly CSV to your bucket.

GA4 import Keep your old history.

Webhooks and counters Count Stripe, Gumroad and GitHub.

Logs, traces, errors

See why a request was slow.

Requests, jobs and queries are timed by the SDK. Errors with the same cause are grouped, with a count and a trend.

Web analytics

Visitors, funnels, sessions. No cookies.

A visitor is a daily-salted hash, so the same person counts once a day. Apps that pass a device_id are counted exactly across days.

Delivery

202 only after the queue has it.

Past your monthly quota, events are still stored and appear the moment you upgrade.

Queued before we confirm
Kept past your quota
Refused only past twice the quota

How the write path works

Monthly quota 104% · 1,040,000 of 1,000,000

The extra 40,000 are kept and shown after an upgrade.

SDKs

Two lines to the first event.

Eight SDKs, a WordPress plugin, a Shopify app and one HTTP endpoint.
