Spotflow

Spotflow is a firmware observability platform for embedded devices. An SDK added to device firmware (Zephyr, nRF Connect, ESP-IDF and FreeRTOS are listed; MQTT is marked as coming soon) streams logs, metrics and core dumps to a web application with dashboards, alerts and crash analysis. The platform also deploys firmware updates over the air with rollout tracking and rollback.

The product is aimed at embedded and IoT engineering teams that operate device fleets. It is offered as a subscription priced by active devices per month, with a free plan for up to 25 devices, paid Production and Enterprise plans for larger fleets, and an option for on-premise or private deployment on the Enterprise tier.

The Czech registry lists Spotflow s.r.o. in Praha, founded on 2023-08-17. The website states that the underlying work started in 2019 on an industrial IoT platform at Datamole, which the site says has scaled to more than 100,000 connected devices, and that the first self-service Spotflow release came in early 2025. The website is published in English and includes documentation, a changelog and a blog on Zephyr debugging topics.
