Manufacturing
Industrial automation platform for SCADA, HMI and MES
- From
- On request
- Rated
- -
The short version
- Only Houdini has a free tier, so it costs nothing to try first.
- Each has a real cost: Ignition requires real engineering to implement; it is a platform rather than a finished application; Houdini houdini Indie at $299 per year requires annual gross revenue under $100K USD
- They diverge on capability: Ignition covers Unlimited-client licensing, Houdini covers Procedural modeling.

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
Houdini
- Houdini Indie at $299 per year requires annual gross revenue under $100K USD
- Houdini Indie cannot be used in the same pipeline as commercial versions of Houdini
- Houdini Indie and Apprentice save to their own .hipnc file format, which commercial Houdini pipelines do not share
- The free Apprentice edition is non commercial, caps render resolution at 1920x1080 and watermarks output images
- Houdini Indie ships with only 2 render tokens
- Full DOP level simulation node access requires Houdini FX at $4,495 per workstation; Core at $1,995 exposes only SOP level pre built simulation assets
- Extra render tokens cost $195

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.
Houdini: How much does SideFX Houdini cost?
SideFX Houdini pricing is not published on their website. Specific prices for commercial, educational, and non-commercial licenses must be obtained by adding items to your cart or contacting SideFX sales directly.
SourceIgnition: 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.
Houdini: What license types does Houdini offer?
Houdini offers Commercial licenses (Houdini Indie for under $100K USD annual revenue, Houdini Core, Houdini FX, Houdini Engine), Non-Commercial licenses (Houdini Apprentice free, Houdini Education for Students and Schools), Rental options, and Annual Upgrade Plans. Volume-based discounts are available for Houdini Engine.
SourceIgnition: 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.
Houdini: Is Houdini available for free?
Yes. Houdini Apprentice is available free for non-commercial use. Houdini Education licenses are also available for students and schools at no cost.
SourceHoudini: Are volume discounts available for Houdini?
Yes. Volume-based discounts are available for Houdini Engine licenses. Rental and Annual Upgrade Plan pricing have been adjusted as of Houdini 21.
