Less data.
More control.

Reduce data usage and transmission costs with compact encoding, secure device communication, and direct delivery to your existing backend.

Everything you need

Define a packed schema, authenticate each frame, store the event, and inspect webhook delivery separately.

Telemetry you can trust

Inspect decoded telemetry, verify device data, and track delivery from one dashboard.

Event visibility

Know exactly what happens to every event.

Struct helps you move beyond raw device data. Inspect decoded fields, verify authenticated ingestion, monitor webhook delivery, and troubleshoot failures across the full path from device to backend.

Inspect decoded data

View stored events, inspect individual fields, and explore telemetry in real time.

Verify trusted ingestion

Understand whether a device event was accepted and identify authentication or payload issues early.

Track delivery status

See whether delivery is pending, sending, delivered, skipped, or failed.

Troubleshoot end to end

Trace individual events across ingestion, decoding, storage, and delivery from one place.

FAQs

Send one event

Create a device, generate its encoder, and watch the stored telemetry in the dashboard.
