Koios

OTA that doesn't brick your fleet.

Canary rings, health-gated promotion, automatic rollback. Push firmware to ten devices or ten million with the same rigor as cloud deployments.

A bad push can turn Tuesday into a crisis

Shipping firmware to devices in the field is the highest-stakes deployment most hardware teams will ever do. A bad push can brick devices, strand customers, and generate the kind of support tickets that keep you up at night.

"Just push it to everyone" is how you end up on Hacker News for the wrong reasons. Koios OTA treats firmware deployment with the same rigor that modern infrastructure applies to software releases.

Delta firmware update representing staged rollout deliveryStaged Rollouts

Canary, Staging, Production

Define deployment stages and promote firmware as confidence builds.

Define rollout rings — canary, beta, staging, production — with configurable promotion criteria. Move firmware through stages as confidence builds. Target by device group, hardware revision, or region.

  • Configurable ring stages
  • Percentage-based targeting
  • Device group filtering
  • Time zone staggering

Every Promotion Earns Its Way

Set pass/fail criteria. Rollouts only advance when devices are healthy.

Set pass/fail criteria based on device telemetry. Rollouts only advance when devices in the current ring are healthy. If a canary device reports issues, the rollout pauses automatically.

  • Telemetry-based health criteria
  • Automatic pause on failure
  • Per-ring thresholds
  • Real-time fleet monitoring

Undo Button for Firmware

If health checks fail, affected devices revert automatically.

If health checks fail, Koios automatically halts the rollout and reverts affected devices to the previous firmware version. No manual intervention. No field visits. No all-hands.

  • Automatic rollback on failure
  • Previous version retention
  • Instant rollout halt
  • Fleet-wide protection

Built for Production Firmware Delivery

Every feature designed to reduce the risk of deploying firmware to devices you can't physically access.

Define deployment stages — canary, beta, staging, production — with configurable promotion criteria. Move firmware through rings as confidence builds.
Industrial sensor monitoring device health during rollout Health-Gated Promotion
Set pass/fail criteria based on device telemetry. Rollouts only advance when devices in the current ring are healthy.

Minimize download size by delivering only the binary diff between versions. Critical for bandwidth-constrained or metered cellular connections.
mTLS certificate chain for authenticated firmware delivery Authenticated Delivery
Devices authenticate with mTLS before receiving firmware. No anonymous pulls. No man-in-the-middle risk. Integrity verified at every stage.
