The short version

  • Each has a real cost: Ignition requires real engineering to implement; it is a platform rather than a finished application; 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: Ignition covers Unlimited-client licensing, Sight Machine covers Unified plant data model.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Ignition

  • Plants where per-tag licensing has made expansion a budget conversationnot Sight Machine
  • Replacing installed operator terminals with browser-based clientsnot Sight Machine
  • Connecting plant floor data to SQL and business systemsnot Sight Machine

Sight Machine

  • A corporate operations team that cannot compare plant performance because every site defines a stoppage differentlynot Ignition
  • A manufacturer whose historian data is plentiful but has never been modelled into anything a business can querynot Ignition
  • A group standardising manufacturing reporting into a cloud data warehouse alongside finance and supply chain datanot Ignition
  • A quality organisation investigating a defect that appears at several plants with different equipmentnot Ignition

Where each one falls short

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

Ignition

  • Requires real engineering to implement; it is a platform rather than a finished application
  • Steep learning curve, and Inductive Automation runs its own training programme because of it
  • Self-hosted and self-supported by default, so plant IT carries the availability burden
  • Module-based pricing means the entry figure is rarely the final one

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.

Questions people ask

Is Ignition or Sight Machine better?
Neither clearly leads. Ignition starts at On request and Sight Machine at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Ignition or Sight Machine?
Ignition starts at On request and Sight Machine at On request.
Does Ignition or Sight Machine run on more platforms?
Ignition runs on Windows, Linux, macOS, Web. Sight Machine runs on Web, API.
What is Ignition best used for?
Ignition is most often used for plants where per-tag licensing has made expansion a budget conversation, replacing installed operator terminals with browser-based clients, connecting plant floor data to sql and business systems. Of those, plants where per-tag licensing has made expansion a budget conversation and replacing installed operator terminals with browser-based clients are not what Sight Machine is typically brought in for.
What can Ignition do that Sight Machine cannot?
Ignition covers Unlimited-client licensing, SCADA and HMI, Historian, MES modules. Sight Machine covers Unified plant data model, Broad ingestion, Cross plant benchmarking, Root cause analysis.

Answered from the vendors’ own pages

Ignition: What does Ignition cost?

It publishes per-server module pricing with unlimited clients, tags and connections, so cost does not scale with how many people use it.

Sight Machine: Is this an OEE product?

It can produce OEE, but buying it for OEE alone is expensive. The reason to buy it is cross plant data standardisation.

Ignition: Why does unlimited-client licensing matter?

Traditional SCADA is licensed per tag or per screen, which turns adding an operator terminal into a purchase. Ignition removes that ceiling.

Sight Machine: Does it need a historian?

It reads from historians, control systems and MES. Some source of machine data is a prerequisite.

Ignition: Is it a finished application?

No, it is a platform. Screens, tags and logic are built for the specific plant, which is real engineering work.

Sight Machine: How long does a plant take to onboard?

Plan in months per plant, depending on how many sources and how inconsistent the existing definitions are.

Sight Machine: Who is the buyer?

A corporate manufacturing, quality or digital function. It is rarely a plant level purchase.
