Buy A Solaros OS Licence
Solaros OS follows a commercial real-time OS model. Pick the edition that fits your development, take a deployment licence to ship it closed-source and royalty-free, and keep full ownership of your code. Every edition ships the same way - Lite free, Plus $100, Max priced by scope.
How Licensing Works
Everything you build with Solaros remains yours. Pick the edition for the capability your system needs, then take a deployment licence to ship it in a commercial product - closed-source and royalty-free. Every edition ships under a deployment licence, and Lite's is free.
Everything you build on the OS belongs to you. No claim on your application logic.
Lite, Plus or Max for the complexity and execution model your system requires.
A one-off deployment licence to ship closed-source and royalty-free - Lite free, Plus $100, Max priced by scope.
Pick Your Edition
Three editions aligned with one architecture, each built for a different class of system. Lite is free for simple, frequency-scheduled task based projects. Plus offers message-driven task scheduling for small products. Solaros EOS Max supports event-driven state machine frameworks for complex, safety-critical systems.
Solaros EOS Max
Behaviourally complex products that still have to run on a small, resource-constrained MCU.
Complex and safety-critical products - medical, automotive, industrial automation and Edge AI.
- Minimal resources and memory footprint
- Maximum performance from your MCU
- Scalable functionality, limited only by code memory
- Greater connectivity and multi-protocol communications framework
- Unlimited events, Active Objects VSMs and state handlers
Solaros OS Plus
Small-footprint products with low to moderate event and interrupt handling.
Embedded systems with modest functionality that still need performance and minimal resources.
Solaros OS Lite
Simple systems with minimal interrupt configurations.
Small projects, hobbyist and educational use.
Every edition ships under a deployment licence - see pricing below. Lite free, Plus $100, Max priced by scope.
Licensed To Ship, Royalty-Free
One deployment licence covers every edition - request it, ship closed-source and royalty-free, unlimited units, and keep full ownership of your code. Price is the only difference: Lite is free, Plus is $100 per product, and Max is priced by deployment scope.

Common Licensing Questions
- What do I pay for?
- You pay for a deployment licence to ship a commercial, closed-source product, and the price follows your edition: Lite is free, Plus is $100 per product, and Max is priced by deployment scope - $3,000 for a single product, $7,000 for a product line, $12,000 for all products at one site. Every edition ships through the same request.
- Do I own what I build?
- Yes. Everything you build with Solaros is yours. The licence is for the Solaros OS runtime, not for your application logic.
- What's the difference between Lite, Plus and Max?
- Lite is frequency-scheduled tasks for simple systems. Plus is task driven message scheduled for small products. Max (EOS) is the only event-driven state machine framework edition, for complex, safety-critical projects. They're based on different code bases with aligned APIs, so Max isn't an upgrade from Lite - it's a completely different execution model, best chosen up front.
- Which deployment licence do I need?
- It depends on your edition. Lite ships free and Plus is $100 per product. Max is priced by scope - Single Product for one product, Product Line for a family, Multi-Product, Single Site for everything built at one location.
