License
Both products are source-available. Free for individuals and small businesses; a paid commercial license covers everyone above that line.
The license
Aleph and Null Memory are both source-available under the PolyForm Small Business License 1.0.0 (SPDX PolyForm-Small-Business-1.0.0). The source is published and you can read it, build it, and run it — but this is not an OSI open-source license. Use is permitted free of charge within the size and revenue limits below; commercial use beyond them requires a paid license.
Required Notice: Copyright 2026 Aleph Null LLC.
Free for small businesses and individuals
You may use both products free of charge if you are a company with fewer than 100 total individuals (employees plus independent contractors) and less than 1,000,000 USD (2019, inflation-adjusted via the US BLS CPI-U) total revenue in the prior tax year.
Self-hosting and building from source for these permitted individual and small-business purposes is already covered by the license — no separate agreement is needed.
Commercial use above the threshold
Above that threshold, a paid commercial license is required. It is per-seat and perpetual, includes 12 months of updates, and is a one-time purchase — no subscriptions.
