pricing

Free for open source. Commercial licence in development.

Kronroe is dual-licensed under AGPL-3.0 for open-source use and a commercial licence for companies that need different terms. Commercial pricing is being designed deliberately — so rather than guess, this page is honest about where it stands today.

Why pricing isn't public yet

I'm a sole maintainer building this in public. Setting commercial pricing too early — before there are enough commercial conversations to know what's reasonable — leads to numbers that are either too high (and lose deals) or too low (and damage long-term sustainability).

So instead of putting up a number that I'd have to defend or change, I'd rather talk. Most early commercial users want a few specific things — perpetual licence vs. subscription, single-product vs. organisation-wide, distribution rights vs. internal use — and the right price depends on which combination matches your situation.

What's available right now

If you're building open-source software compatible with AGPL-3.0, you can use Kronroe today, free, with no further conversation needed.
If you're building commercial software and need different terms, email me. We'll work out a licence that makes sense for your situation. Early customers get founder pricing.
If you're not sure which applies to you, also email me. AGPL is genuinely viral in some software designs and benign in others, and a 5-minute conversation usually clarifies it.

What you can expect when pricing lands

When the commercial pricing is published, it'll likely follow this shape:

A per-product perpetual licence for shipping Kronroe embedded in a commercial application
An organisation-wide annual subscription for internal use across multiple products
OEM pricing for distributing Kronroe inside other developer-facing tools
Founder pricing for early customers who agree to multi-year terms before the public price ships

Existing licensees won't have their terms increased retroactively when public pricing arrives. The commercial licence text already exists; only the price is in flux.

Want a commercial licence?

Tell me what you're building and what shape of licence would work. Most early conversations close in a week or two, with founder pricing that beats whatever the public number ends up being.
