AyMON
Editions & Licensing
Start free
An engine with no licence file is not crippled. It is a small plant.
With no licence at all AyMON runs the FREE edition. It never expires, it includes every protocol and every plug-in, and within its limits you may use it for anything — commercial and production use included. FREE is also the edition for personal projects; there is no separate personal licence.
Cluster, replication, RPC and MCP are not switched off without a licence: they work between engines on one machine and are refused towards another one. So you can learn every commercial feature end to end. What is sold is the second machine — and more connections, devices and users.

How a licence works
A signed file, read once at start
One plain-text file
AyMON.lic is signed. Any edit breaks the signature and the engine falls back to FREE, saying so in its log.
Bound to its place
A licence is issued for a machine and a project; copied elsewhere it is reported and not used.
Nothing stops at run time
The decision is made at start. A plant does not stop because a date passed; a new licence means a restart.
One line tells the truth
The start-up log names the edition, the limits and the features that are off — and why.
Patents
Patent pending
The AyMON engine implements mechanisms described in Canadian patent application No. 3,307,314, Deterministic Event-Driven Industrial Execution Engine with Unified Bitfield State Architecture and Type-Driven Queue Scheduling, filed on 6 April 2026 and pending. AKYA Canada Inc. holds an exclusive licence to it.
Running the AyMON engine as its licence permits — the FREE edition included — includes the right to practise the application as far as running the engine needs. It does not include a licence to implement the described mechanisms in another engine, product or service, and neither do the example projects, which configure and describe them.
