Open source
Apara
Open source.
Effective 27 October 2026. Apara stands on decades of open-source work. This page lists it, and tells you how to get the source.
Components
Apara’s runtime is assembled from the projects below. The authoritative list for any specific build is the manifest.json inside that build’s runtime bundle, which records each component’s exact version, source hash, licence and source location; full licence texts ship in the bundle’s LICENSES folder.
| Component | Licence | Modified | Upstream |
|---|---|---|---|
| Wine | LGPL-2.1-or-later | Yes — Apara patch series | source |
| DXVK | zlib | Yes — one patch | source |

Written offer for source code
For any component above licensed under the GNU LGPL or GPL, and for Apara’s own modifications to it, we will give anyone who has received a binary from us the complete corresponding source code — including our patches and the scripts used to build it — for a charge no more than the cost of physically providing it, or free as a download. This offer is valid for at least three years after we last distribute that binary.
To request it, write to hello@apara.dev with the subject line “Source request” and the Apara version you have. Where source is published in a public repository, that repository is listed in the build’s manifest.
The LGPL lets you modify these libraries and use your modified version with Apara. Apara loads them as separate, replaceable libraries so that you can.
What Apara never ships
Microsoft’s redistributables and Microsoft’s Core Fonts are never bundled with Apara. Apple’s D3DMetal is not part of Apara either: it is Apple’s software under Apple’s licence, offered to beta testers as a separate download through Apara, and obtained from Apple by everyone else. Where a route uses these, the files come from your own installation or are fetched by your own Mac from their publisher, under that publisher’s licence.
Thanks
To the Wine project and its contributors, to CodeWeavers for publishing their open-source changes, and to the DXVK, MoltenVK, vkd3d, Mesa, FEX and GStreamer communities. Apara is not affiliated with or endorsed by any of them.
