Is MQTT or Nest better?

Neither clearly leads. MQTT starts at Free and Nest at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, MQTT or Nest?

MQTT has a free tier; the other does not. Paid plans start at Free for MQTT and On request for Nest.

Does MQTT or Nest run on more platforms?

MQTT runs on Any platform, Embedded devices, Cloud, Edge computing. Nest runs on Hardware, Mobile, Web.

Can I use MQTT for free?

Yes. MQTT has a free tier, so you can try it without paying. Nest starts at On request.

What is MQTT best used for?

MQTT is most often used for iot messaging, sensor data, real-time updates, device telemetry. Of those, iot messaging and sensor data are not what Nest is typically brought in for.

What can MQTT do that Nest cannot?

MQTT covers Publish-Subscribe, Lightweight, QoS Levels, Retained Messages. Nest covers Learning Thermostat, HD Cameras, Smart Alerts, Energy Savings.

The short version

Only MQTT has a free tier, so it costs nothing to try first.
Each has a real cost: MQTT mQTT is an OASIS standard messaging protocol maintained by a standards committee, not sold by a vendor; there is no company-controlled price list, subscription, or edition to compare because implementations are independent open source or commercial products built on the spec; Nest pricing not published in support documentation; individual product prices vary significantly
They diverge on capability: MQTT covers Publish-Subscribe, Nest covers Learning Thermostat.

Where each one falls short

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

MQTT

MQTT is an OASIS standard messaging protocol maintained by a standards committee, not sold by a vendor; there is no company-controlled price list, subscription, or edition to compare because implementations are independent open source or commercial products built on the spec

Nest

Pricing not published in support documentation; individual product prices vary significantly
All Nest products require Google Home ecosystem integration for full functionality
Smart home devices operate only within the Google Nest ecosystem; limited third-party interoperability
Support and product documentation dispersed across Google support rather than centralised Nest site
