The Next platform in this IDE runs the official ZX Spectrum Next system software (NextZXOS 2.09 / System/Next 24.06) inside a WebAssembly emulator. The system software is copyright its authors and is redistributed here under the terms below. This page reproduces those terms in full so they are readable without booting the machine.
This IDE serves the NextZXOS ROMs and a bootable SD image to your browser so the emulator can start. The Next Licence permits redistributing the Distribution, and the Sinclair / ZX Spectrum ROM images inside it are used under the permission Amstrad / Sky plc grant for emulators (see clause on ROM images below). The software is provided free of charge and is never sold.

Furthermore you cannot charge a duplication fee. * The "Sinclair/ZX Spectrum Next" logo screen cannot be used by other systems built from the schematics / source code contained herewith nor can the derivative systems be identified as "ZX Spectrum Next" computers unless they are produced by SpecNext Ltd. In case of a system that is an exact replica of the TBBlue mainboard built without further modifications, the builder must replace the startup screen with one that displays the TBBlue logo (included in the sources). In case of a modified replica, that uses the same VHDL sources, the builder can sport any logo/name of their choosing in the resulting core except the aforementioned. * Certain parts of the Distribution can place their own restrictions on copying, modification, merging and distribution and these are independent and supersede the force of the Next license. For example, ROM images contained herewith cannot be distributed nor modified legally without the permission of Amstrad / Sky plc except in cases already permitted by them (i.e. emulators). * Modifications of parts of this Distribution are permitted pursuant to their individual licenses. Individual parts licenses of the distribution supersede the force of the Next License. * Copyrighted names and trademarks contained within this Distribution are not transferred with the Distribution itself and remain the property of their individual owners. * Usage of the entirety of this Distribution on hardware other than what it was intended for, is expressly permitted provided the Distribution is transmitted /duplicated in its entirety except in the cases where there's an express permission of individual copyright holders directly to the modifier of this Distribution to do so. For example you could distribute only the free parts of this Distribution for another system AND obtain permission to distribute parts of software contained herewith that are not normally allowed to be distributed IF you can obtain permission to do so by the owner of the copyright of the parts for which distribution is denied. * The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Distribution together with ALL individual licenses of all constituent parts of the Distribution. * All software parts of this Distribution are considered automatically "Closed Source"/"Further distribution denied" individually if they are NOT accompanied by a license and "Open Source"/"Further distribution permitted" under the MIT license if they include source code located under /src/ even if they don't include a license. If they DO include a license (found under /docs/licenses) that license shall be in force. * All media/document parts of this Distribution are considered automatically to be covered by the Attribution-NonCommercial-ShareAlike CC BY-NC-SA license if they do not include a license under /docs/licenses otherwise the latter license is in force. * All contributors to the Distribution are individually responsible for the legality of their submissions and SpecNext Ltd. shall not be held liable for any violations of copyright stemming from individual contributions to the Distribution other than the contribution of itself. * An exception to the transmission, copying of the Distribution's entirety is allowed as to NOT include source code where this is applicable provided the copy includes a link to the source code itself.
