Sources
Most tools stop at events.
Tell doesn’t.
Events, web traffic, logs, metrics and business data land in one timeline. When a number moves, the reason is already next to it. One tool instead of four, and no exports in between.
Product events
Track, identify, revenue. Funnels and retention on top.
Web traffic
Page views, sessions, referrers. No cookie banner.
Logs
Structured app logs, syslog from any device, PII redacted in flight.
Metrics
CPU, memory, disk, network and containers, every 15 seconds.
Business snapshots
MRR, orders, stars, ad spend. Pulled on a schedule, kept as history.
Your databases
Join against tables that stay where they are. Nothing copied.
Tell wire protocol
A compact binary protocol, so SDKs and agents ship data with almost no overhead. HTTP, Syslog, OTLP and Modbus are accepted too, so nothing you already run has to change.
Agents & protocols
no code changesUnderstand the full user journey
See how users move through your product — where they convert, what keeps them engaged, and where you lose them.
Convert more users
Drive engagement
Retain and grow
Predict churn
See what your systems are telling you
Structured logs and infrastructure metrics in the same store as your product events — so "errors spiked" and "signups dropped" are one query, not two tools.
Catch issues early
Debug faster
Monitor every service
Stay compliant automatically
Your growth channels, charted next to your product
GitHub stars, YouTube subscribers, ad performance, and Stripe revenue land in the same store as your product events — one chart away from signups and retention.
10 connectors, zero pipelines
Connect Stripe, GitHub, or YouTube once — Tell pulls the numbers on a schedule and charts them next to your product data. Build your own with a plugin if a source is missing.
