The short version

  • Each has a real cost: AVEVA PI System pricing is not published and comes through an account representative; Sight Machine onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • They diverge on capability: AVEVA PI System covers Real-time data collection, Sight Machine covers Unified plant data model.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

AVEVA PI System

  • Pricing is not published and comes through an account representative
  • The vendor is moving to a subscription commercial model, so perpetual licence expectations no longer hold
  • Made up of several separately named components, including PI Server, PI Vision, Edge Data Store and the adapters and connectors needed per data source

Sight Machine

  • Onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • It assumes the instrumentation already exists, so a plant whose machines produce no usable data gets nothing from a data platform and needs to solve connectivity first with a different class of product.
  • Pricing scales with plants and data volume and is never published, which puts it out of reach for single site manufacturers regardless of how relevant the capability sounds.
  • It is not an MES and does not control or execute anything, so it sits on top of the operational systems and adds a layer to maintain rather than replacing one.
  • Success depends on a central team that owns definitions and enforces them, and in groups where plants retain autonomy the standardisation the platform provides gets quietly ignored at site level.
