Where our name comes from

caldera (n.) the deep basin left when a volcano collapses into itself. The structure only shows once you look beneath the rim.

Caldera maps live infrastructure the same way: every layer down to the core, drawn as terrain you can read.

01. What we build

A live atlas of your stack

Traces, metrics and logs become layered terrain. Services are landforms. Dependencies are ridgelines. Incidents are faultlines you can walk.

02. How it works

Connect, map, descend

Point your telemetry at Caldera and the map draws itself in minutes. When an alert fires, follow it down: symptom at the surface, cause at the core.

Every incident has a shape.
We draw it.

02 / Principles

See the unexpected

Dashboards answer the questions you thought to ask. Terrain shows you the ones you didn't.

“The greatest value of a picture is when it forces us to notice what we never expected to see.”John W. Tukey

The map is not the territory

So we redraw the map from live telemetry, continuously, and never let it drift from what is actually running.

“A map is not the territory it represents.”Alfred Korzybski

Insight over output

Another chart is noise. Knowing where you are, and what is underneath you, is signal.

“The purpose of computing is insight, not numbers.”Richard Hamming
