The short version

  • Only Prometheus has a free tier, so it costs nothing to try first.
  • Each has a real cost: Juniper Mist wi-Fi Assurance is a required subscription, not optional support, so the AI-driven monitoring that is the product's core selling point cannot be declined while still running the hardware in a supported way; Prometheus not suitable for per-request billing as collected data lacks 100% accuracy
  • They diverge on capability: Juniper Mist covers AI-driven assurance, Prometheus covers Multi-dimensional Data Model.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

Where each one falls short

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

Juniper Mist

  • Wi-Fi Assurance is a required subscription, not optional support, so the AI-driven monitoring that is the product's core selling point cannot be declined while still running the hardware in a supported way
  • Pricing is entirely quote-based with no published list price, and third-party estimates of typical contract size vary widely, making it hard to budget before engaging Juniper sales
  • Premium Analytics is priced as a further add-on beyond the already-required base subscription, so the full-featured cost is higher than the headline Wi-Fi Assurance price alone
  • As with other cloud-managed hardware in this category, ongoing cloud connectivity is required for full functionality, and local resilience during an internet outage should be verified before purchase
  • Deployment-level licence attachment eases hardware swaps but still means the licence, not the hardware, is the thing actually being renewed and paid for indefinitely
  • Juniper's acquisition of Mist folds product direction into Juniper's broader roadmap and pricing strategy, which has already shifted since acquisition and may shift again

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection
