Golioth vs ESP RainMaker

How Golioth and ESP RainMaker differ on target hardware, rollback, deployment and cost.

GoliothESP RainMaker
TypeMCU cloudVendor platform
TargetsMCU (Zephyr-first)ESP32 family
DeploymentSaaSSaaS (Espressif) or self-hosted on AWS
RollbackManual release targeting; rollback by publishing a prior artifactOTA partition scheme with rollback support in ESP-IDF
How it worksOne consumption meter instead of plans: $0.25 per connected device per month, $0.0095 per megabyte of OTA traffic, and separate rates for logs and streaming data. Every account gets the same features, which makes small fleets cheap and makes cost forecasting arithmetic rather than negotiation.A device cloud built around ESP-IDF: claiming, provisioning, phone apps, voice assistants and OTA, all supplied by the chip vendor. ESP-IDF’s own OTA partition scheme handles the rollback, and the whole stack can be deployed into your own AWS account.

Best forZephyr projects that want predictable unit costProducts built on ESP32 silicon

Golioth

  • Cheapest credible option at small and mid scale
  • Cost is calculable before you commit
  • Deep Zephyr integration
  • Zephyr-centric — other RTOSes are less travelled
  • Metered bytes need watching on chatty fleets

ESP RainMaker

  • Free to develop and evaluate
  • Whole stack from silicon vendor — no integration gap
  • Reference phone apps save real months
  • ESP32 only
  • Commercial terms at scale are not published

Bottom line

Choose Golioth for zephyr projects that want predictable unit cost. Choose ESP RainMaker for products built on esp32 silicon.
