The short version

  • Each has a real cost: Losant no public pricing available; customizable pricing model requires sales contact before cost clarity; Eclipse Mosquitto there is no clustering: Mosquitto is a single process, so high availability means building your own failover and accepting session loss on switchover.
  • They diverge on capability: Losant covers Device Connectivity, Eclipse Mosquitto covers MQTT 5.0 support.

Where each one falls short

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

Losant

  • No public pricing available; customizable pricing model requires sales contact before cost clarity
  • Customers must fill out survey form before sales team provides any pricing details
  • Unable to estimate budget or compare costs against competitors without direct engagement

Eclipse Mosquitto

  • There is no clustering: Mosquitto is a single process, so high availability means building your own failover and accepting session loss on switchover.
  • Persistence is a local file rather than a replicated store, so a disk failure or an unclean shutdown can lose retained messages and queued QoS traffic.
  • Practical capacity is a few thousand concurrent clients on typical hardware, so a growing device fleet eventually forces a migration to a clustered broker.
  • The Eclipse Public Licence is weak copyleft rather than permissive, which some legal teams treat as a blocker when embedding the broker in a shipped commercial product.
  • There is no commercial support to buy from the project, so production incidents rely on community mailing lists or on paying a third party who happens to know the codebase.
