About
Blynk is a low-code IoT platform for connecting devices, building mobile and web dashboards, and managing fleets from a managed cloud. The platform includes mobile apps, a web console, device provisioning and authentication, automations, OTA updates, and hardware connectivity over MQTT, HTTP, Webhooks, Wi-Fi, cellular, LoRaWAN, and satellite.
The free plan includes 5 devices, 1 user, 1 week of data retention, and 100,000 messages. It is aimed at exploration and early prototyping, while paid plans add higher device limits, longer retention, RBAC, multi-tenancy, and enterprise deployment options such as private cloud and on-premise hosting.

Free Tier Value
This free tier is a genuinely usable capped plan rather than a short trial: it includes a small device/user allowance, a week of retention, and enough monthly messages to test a real deployment. Compared with the $29 Starter plan, it keeps the premium widgets and data converters but with much tighter limits, so a fair buyer-side estimate is about $12/month, or roughly 40% of Starter's value.
