Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arduino Cloud

  • The free plan allows 2 connected devices, 5 variables each and one day of data retention
  • Free accounts are limited to 25 compilations a day and 10 trigger notifications a day
  • The Maker plan at $72 a year lifts devices to 25 and retention to 3 months, still for a single user
  • Team pricing jumps to $1,000 a year
  • Two years of data retention and unlimited ingestion require Enterprise

Blynk

  • The free tier covers 5 devices, 1 user, 100,000 messages and one week of data retention
  • Data retention is tiered all the way up, reaching 12 months only on Enterprise
  • Automations and webhooks are rationed, from 5 scenarios and 1 webhook on free to 100 or more on Production
  • Over-the-air update campaigns are capped by tier, at 2 shipments on free and Starter
  • Production plans run from $199 to $1,099 a month depending on device count
