Features
Five primitives, designed to compose. None of them require a data engineer.
Watch conversions update live as events arrive. Median ingest-to-chart latency under 800ms — fast enough to debug a release.
Events are TypeScript types. Rename one and it propagates across queries, dashboards, and SDK calls — no silent string drift.
type Events = { 'signup.completed': { plan: 'free' | 'pro' } 'checkout.viewed': { amount: number } 'invite.sent': { count: number } } stratus.track('signup.completed', { plan: 'pro', })
Build retention curves and segments visually. Export the underlying SQL when you need to ship it to your warehouse.
| Cohort | D1 | D7 | D30 |
|---|---|---|---|
| Wk 0 | 100% | 64% | 38% |
| Wk 1 | 100% | 69% | 41% |
| Wk 2 | 100% | 72% | 44% |
| Wk 3 | 100% | 76% | 47% |
Tie events to deploys. See exactly which release moved the needle — or broke checkout.
PII filtering, EU residency, SOC2-ready. Compliance is a config flag, not a six-month migration.
How it works
A single typed import. No build step, no proxy, no agent. Works in any modern JS runtime.
Events are first-class TypeScript types. Refactor renames the event everywhere — no orphaned strings.
Build funnels, retention, and cohorts visually. Export the underlying SQL when you need it.

Testimonials
"Replaced a $1,400/month tool in an afternoon. The funnels just work."
Maya Okafor
Head of Product · Northwind Studios
"We tried three other analytics tools first. The thing that finally stuck was the typed-event model — our junior engineers stopped accidentally creating new event names every sprint, and we stopped having Monday-morning meetings about which dashboard was the real one."
Theo Larsen
Founding Engineer · Lumen Labs
"I have been doing analytics tooling for fifteen years and Stratus is the first product where the visual builder and the SQL escape hatch agree on what the answer is. That sounds boring on a landing page. It is the entire reason we switched. Two engineers maintained our previous setup. Zero engineers maintain Stratus, because there is nothing to maintain."

FAQ
Most teams are sending real events within five minutes — install the SDK, paste your write key, and ship. Defining typed events takes another 15–30 minutes for a typical product surface.
Yes. Pick eu-west-1 at project creation and every event, query, and backup stays in the EU. Region is locked once a project is created.
Settings → Billing → Cancel. No call, no retention loop. Your data stays read-only for 30 days so you can export, then it’s deleted on the 31st.
Yes. Data is encrypted in transit (TLS 1.3) and at rest (AES-256). We’re SOC2 Type II as of 2025. Penetration tests are run quarterly by a third party and the report is available under NDA on the Team plan.
Yes. We ship importers for the three most common platforms, and the schema accepts the standard track / identify / page shape, so a one-line proxy is usually enough during the cutover.
Nothing breaks. We keep ingesting events and surface a soft warning in the dashboard. You have a full month to upgrade, downgrade volume, or move on. No surprise charges.
The cloud product covers 99% of our customers and we keep it that way intentionally. For regulated industries that genuinely need self-hosted, the Team plan includes a single-tenant deployment option — talk to us first so we can size it correctly.
