A Factory IO Alternative That Runs in Your Browser

Factory IO is a great 3D factory visualisation tool — if you have Windows and already own a PLC IDE licence. If you do not, here is an honest look at what to use instead.

Opening honesty

We make one of the tools being compared.

We have tried to be fair to Factory IO. Read the Factory IO side below before you form an opinion. In one sentence: Factory IO is the better tool if you want beautiful 3D factory commissioning and already own TIA Portal or Studio 5000. Ours is the better tool if you want to practise writing PLC code right now, on any device, without buying a vendor licence first.

Background

What Factory IO actually is

Factory IO is a 3D factory simulator from Real Games, a Portuguese studio that has been building industrial training software since the early 2010s. You drag factory components — conveyors, pushers, pneumatic cylinders, sensors, stackers, arms — into a 3D scene, then connect that scene to a real PLC program running elsewhere (TIA Portal, Studio 5000, Codesys SoftPLC, Do-more Designer) via OPC UA or Modbus TCP.

Pricing is a one-off purchase: roughly $29 for a Student licence, $190 for an Individual licence, and contact-for-quote for company site licences. It runs on Windows only. Factory IO does not include a PLC IDE — you bring your own, which means the sticker price is only a small part of the true cost.

Strengths

What Factory IO does well

3D visualisation

The 3D rendering is genuinely impressive — boxes fall, pushers nudge, arms stack. Watching your code drive a photoreal line is a different kind of feedback than any 2D simulator gives.

Component library

Hundreds of pre-built industrial parts: belts, gates, weighing scales, pick-and-place arms, label printers. You can build a realistic line in an hour.

Vendor-IDE integration

The OPC UA / Modbus TCP bridge lets you run your real TIA Portal or Studio 5000 program against the 3D scene. If your day job uses one of those IDEs, Factory IO feels continuous with it.

Learner pain points

Where Factory IO falls short if you are still learning

Windows-only install

If you are on a Mac, Linux box, Chromebook, or any locked-down work device, Factory IO is a non-starter without a Windows VM and another Windows licence.

Requires a separate PLC IDE

Factory IO is the scene, not the program editor. You pair it with TIA Portal, Studio 5000, Codesys, or similar — each of which is its own install, its own cost, and its own learning curve.

Licence cost stacks fast

$190 for Factory IO plus roughly €1,200/yr for a TIA Portal Basic licence or $2,500/yr for Studio 5000 Standard is a lot of money to get to your first rung of ladder.

No built-in curriculum

You get a box of 3D parts, not a scored syllabus. There is no auto-grader telling you whether your program actually solves the scenario — you decide by watching the line run.

Pick Factory IO if…

  • You are on Windows already.
  • You already own TIA Portal, Studio 5000, or Codesys.
  • You want 3D visualisation as a priority.
  • You are doing pre-commissioning or digital-twin work.
  • You are an instructor with a Windows lab and licence budget.

Pick us if…

  • You are on a Mac, Linux machine, or Chromebook.
  • You do not have a TIA Portal or Studio 5000 licence.
  • You want scored feedback, not visual-only feedback.
  • You want to practise IEC, Allen-Bradley, and Siemens dialects side-by-side.
  • You are doing interview prep in the next four weeks.
  • You want a free tier with no credit card.

Third options

Neither fits? Here is what else to consider.

  • LogixPro 500 — classic Allen-Bradley SLC 500 classroom simulator. Dated but well-known in US colleges. See our LogixPro alternative comparison.
  • Codesys — the industry-reference IEC 61131-3 IDE, free to download, runs its own SoftPLC simulation. Windows-only and demo mode shuts down after 2 hours. See our Codesys alternative comparison.
  • PLC-Fiddle — the lightest possible "try ladder in 30 seconds" browser tool. Ladder-only, no scored scenarios. See our PLC-Fiddle alternative comparison.
  • OpenPLC on a Raspberry Pi — if you want real hardware for under $100 and do not mind a serious setup weekend.

Complementary use

Many learners actually use both

Drill fundamentals with us — scored feedback, any OS, no install — and graduate to Factory IO on a Windows machine when you want the 3D commissioning feel and are already working in TIA Portal or Studio 5000. The two tools answer different questions and do not compete head-on for a serious learner's time.

Questions

Factory IO alternative FAQ

Not identical. Factory IO renders a 3D factory scene and expects you to bring your own PLC program (from TIA Portal, Studio 5000, Codesys, etc.). Our simulator does not draw a 3D factory — instead it models the control problem as a scored scenario (sensors, actuators, test cases) and grades your ladder or structured text automatically. If you want photoreal 3D and already own a vendor IDE, Factory IO is the better tool. If you want to practise writing PLC code on Mac, Linux, or Chromebook without buying a vendor licence, we are.
