Open source

Built on shared work.

InkHub includes open-source software. Paying for hosted installation does not remove the rights those licences give you.

Source that matches your download

InkHub 1.0.0 includes its corresponding source archive, dependency sources, build instructions, patches and licence notices alongside the downloads, at no extra charge. The same applies to future OTA releases.

Our public release repository is separate from our private development workspace. Download the explicitly labelled corresponding-source archive for your version, not GitHub’s automatically generated repository ZIP.

Different components, different licences

InkHub’s default is GPL-2.0-or-later. Components retain their own licences, including Slint-linked applications and KOReader. The complete release inventory, rather than a single blanket label, determines the applicable terms. The independently developed hosted installation service remains proprietary; that does not restrict your rights to the open-source device software.

Software already on your device

Some devices require their existing vendor display components. Those are not automatically licensed for redistribution simply because they run on the same brand of hardware. InkHub uses the required vendor components already present on the supported device; device-owned display waveforms and stock recovery data are not included in the public downloads.
