Your system works as one. Your tools see it in pieces.

A single event can span firmware, controllers, sensors, and equipment, but the evidence ends up split across telemetry viewers, logs, test systems, scripts, and team conversations. Understanding what happened means finding each piece and rebuilding the full picture by hand.

One event spans the system.

A firmware change, test step, or hardware fault can surface across sensors, controllers, and equipment at the same time.

Each tool captures one piece.

Telemetry, logs, recorded runs, test results, and team context live in separate tools and formats.

Engineers rebuild the full picture.

Before they can investigate, engineers have to export, convert, align timestamps, write scripts, and share the result.

One workspace for the whole system.

Zelos brings everything around your hardware system into one shared workspace.

Bring your data together.

Investigate any run.

Keep the answer with the data.

Built for the full hardware lifecycle.

Develop firmware, validate systems, and operate production hardware with the same data, tools, and shared context.

Panels for every workflow

Choose and arrange the views your work needs, from live monitoring to detailed analysis.

Measure like a scope

Place paired cursors on real samples to measure timing and signal changes precisely.

One cursor, every panel

Scrub, step, or jump through time and the whole workspace follows.

Values in context

Choose how each signal is displayed while preserving the state labels defined by your system.

Record every run

Capture each run as a portable trace you can reopen, inspect, and share.

Compare runs side by side

Open live and recorded data together, then align each run around the moment that matters.

Fast at every scale

Move smoothly from a single event to hours of data without losing the detail you need.

Record what matters

Capture changes, thresholds, and heartbeats without filling traces with redundant samples.

Tests that understand time

Express what should always, never, or eventually happen across live and recorded data.

Control beside your data

Expose validated controls in the workspace, with live results and no separate control UI to maintain.

SDKs for your stack

Stream structured data with typed schemas, units, and metadata from the code you already run.

Automate from the terminal

Connect, query, export, and test the same system from scripts and CI.

Shared layouts

Save the way your team works and give everyone the same view.

Connect your systems

Install supported integrations or build an extension for the hardware and protocols you use.

Open data

Query traces with your own tools or move results into the formats your workflow expects.

Private by default

Operational data stays on your infrastructure. AI requests use zero-data-retention processing by default and are never used to train models.
