Pricing
The coordination bus is free and open-source. A commercial licence — pay what you want — only removes the AGPL copyleft for closed-source and SaaS use. Same code, different terms.

Frequently asked questions
Can I use SYNAPSE CHANNEL for free?
Yes. The open-source AGPL-3.0 licence is free for research, personal use, and open-source software. If your own project is open-source, you never need a commercial licence.
When do I need a commercial licence?
If you embed SYNAPSE in closed-source software, or run it inside a SaaS whose source you do not publish, the AGPL-3.0 would require you to release your full stack. A commercial licence removes that obligation.
Why "pay what you want"?
CHF 9.99 is the floor — enough to say "this is worth supporting". If SYNAPSE coordinates a fleet that earns you real money, paying more funds the research, electricity, and tokens that keep it improving. It is the same model that makes the tool sharpen itself: we run our own work on it, so the friction we hit becomes the next fix.
Is the paid version different from the free one?
No. The package on PyPI is the whole product. There is no feature gate — only the licence terms differ. Try it free, buy a licence when you ship something closed-source.
What exactly does the Indie licence cover?
The AGPL-copyleft exemption for one closed-source product, perpetual for the version line you buy, with patch and minor updates during the term. See the full terms in COMMERCIAL-LICENSE.md.
Can I pay with Stripe or PayPal?
Checkout runs through Polar.sh (Merchant of Record, so VAT/withholding is handled). Prefer a direct Stripe or PayPal invoice link? Email protoscience@anulum.li and we will send one.
Need a custom arrangement?
OEM licensing, academic or non-profit use, a hosted multi-tenant hub, or just an invoice in a particular form — get in touch and we will find the right terms.
