Open-core licensing
Nyxis is infrastructure software with explicit legal boundaries — not opaque enterprise sales. Stay on the free BSL tier when you qualify; otherwise map revenue and monthly throughput to Startup/Growth, Enterprise Core, or a Principal custom contract.

Use these answers to filter your evaluation before engaging sales — most teams know their tier from revenue and throughput alone.
If your company makes over $5,000,000 USD in gross annual revenue, or your production applications serialize or deserialize more than 10 TB of .nxb payloads across your network lanes in a single calendar month, your standard BSL 1.1 allowance expires. You must step into a paid commercial agreement.
Because Nyxis relies on constant-time pointer casting instead of full-file heap parsing, scaling past 10 TB/month does not inflate browser or worker memory the way repeated JSON.parse() pipelines do. See the V8 allocation parity matrix on the use-cases page for the technical breakdown.
After you exceed the free BSL gates, pick the paid package that matches both your revenue band and monthly throughput: Startup / Growth when you are under $10M revenue and under 1 TB/month; Enterprise Core when you are in the $10M–$100M revenue band or processing 1–50 TB/month; Principal when revenue exceeds $100M or throughput exceeds 50 TB/month.
Enterprise extensions (compactor, encrypt, replicate, query proxy, Arrow bridge, schema registry, SIMD guard) align with these packages — see the tier cards above and COMMERCIAL.md.
No. All client-side readers and writers (nyxis-drivers) are licensed under the ultra-permissive MIT license. You can embed them in edge applications, mobile devices, IoT hardware, or client browsers with absolutely zero copyleft or compliance friction. Only the core compilation engine and private performance daemons require a commercial seat.
Either gate triggers the need for a commercial license. You must comply with both the revenue cap and the monthly throughput cap to remain on the free tier. Crossing either threshold moves you into Startup / Growth or higher, depending on your revenue and monthly data volume.
Enterprise architects and procurement teams can open a thread with tier, cluster footprint, and target go-live date.
