Commercial Licence

Copyright (c) 2025 SpaceCell Enterprises Ltd. All rights reserved.

Overview

SIMD-Kernels is dual-licensed. The open-source licence is AGPL-3.0, which requires any software that uses or incorporates SIMD-Kernels to be released under the same terms. If you cannot or do not wish to comply with the AGPL-3.0, a commercial licence is available.

When You Need a Commercial Licence

A commercial licence is required if you:

  • Integrate SIMD-Kernels into a proprietary product or service
  • Distribute software incorporating SIMD-Kernels without releasing your source code under AGPL-3.0
  • Use SIMD-Kernels as part of a SaaS or hosted service and do not wish to comply with AGPL-3.0 network use provisions
  • Embed SIMD-Kernels in a commercial SDK, library, or data platform

What the Commercial Licence Provides

  • The right to use, integrate, and distribute SIMD-Kernels in proprietary software without AGPL-3.0 obligations
  • No requirement to disclose or open-source your application code
  • No copyleft obligations on derivative works
  • Rights to use all current and future versions released during the licence term, subject to agreement terms

What the Commercial Licence Does Not Cover

  • Resale or sublicensing of SIMD-Kernels itself as a standalone product
  • Removal of copyright notices from source files
  • Any warranty of fitness for a particular purpose or guaranteed accuracy - see the disclaimer below

Licence Terms

Standard Commercial Licence - £10,000 per organisation (perpetual)

Includes a 12-month maintenance period covering updates, new statistical methods and distribution families, and compatibility with std::simd stabilisation changes. Thereafter, an optional annual maintenance subscription of £2,000 per organisation is available to continue receiving updates.

OEM / Redistribution Licence

If you intend to embed SIMD-Kernels in a product or SDK distributed to third parties, an OEM licence is required. OEM terms are negotiated individually based on redistribution scope. Contact us to discuss.
