FEATURES

Every signal on one timeline.

Logs, traces, errors, alerts and dashboards in one product, with one search box and one bill. Here is what each part does and why teams switch.

LOGS

Logs you can read

Search a billion lines in under a second. Fields are parsed for you, so you filter by customer or order instead of writing regex.

0.8 s median search

TRACES

Traces across every service

Follow one request from the browser to the database. Each hop shows its time, its logs and the code that ran.

23 services in one view

ERRORS

Errors grouped by cause

Similar crashes fold into one issue with a count, the first release it appeared in and the users it hit.

9,400 events → 12 issues

ALERTS

Alerts that stay quiet

Alert on what customers feel, like slow checkouts or failed logins, not on every CPU spike at 3 a.m.

61% fewer pages

ASK

Answers in plain English

Ask "why did checkout fail at 14:02?" and get the trace, the log line and a likely cause back.

DASHBOARDS

Dashboards your team shares

Build a board in minutes from any query, then share one link with support, product and on-call.

Live, no refresh button

01 · TRACES

Follow one request through every service.

A trace shows each hop a request takes, how long it spent there and what it logged on the way. Slow or failing hops are marked for you.

02 · ERRORS

Thousands of crashes, a dozen real problems.

Tessellary groups errors with the same cause, counts the users each one reached and shows the release that introduced it, so the team fixes the right thing first.

03 · ASK

Ask a question, get the trace that answers it.

Type what you would ask a teammate. Tessellary turns it into a search, shows the query it ran and links every claim to the log line or trace behind it.

Why did checkout fail for customers in Germany yesterday afternoon?

Between 14:01 and 14:19, 212 checkouts failed. All of them called the payment provider from eu-central, which timed out after 200 ms. The retry timeout was lowered in release v4.18.0 at 13:58.

04 · SECURITY

Built for data you would rather not leak.

Sensitive fields are masked before they leave your servers, and every plan keeps your data in the region you pick.

Masking on your server

Card numbers, emails and tokens are removed by the SDK, so they never reach us.

Choose your region

Keep data in the EU or the US. Scale plans can pin it to one country.

Single sign-on

Sign in with your identity provider and manage access by group.

Audit log

See who searched what and when, exportable for your auditors.

Encrypted everywhere

TLS in transit and AES-256 at rest, with keys rotated every 90 days.

Independent audits

SOC 2 Type II and ISO 27001 reports available on request.
