As some of you know, I worked the last 2 years on porting the desktop client from electron to tauri:
- NLnet; Delta Tauri
- deltachat-desktop/packages/target-tauri at main · deltachat/deltachat-desktop · GitHub
Currently the plan is to release the tauri edition additionally to the electron version and start testing it to find out if it is stable enough to become the main edition and replace the electron edition.
I’m writing this forum post because the first tauri test release is released and ready for testing. There are also a few new features, that are also in the electron edition, but there will be a dedicated forum post about those soon (quick access to recent webxdc apps and more).
Releases can be found here: Release v1.59.1 2025-05-29 · deltachat/deltachat-desktop · GitHub
(mind that this contains both electron and tauri editions, so look at the file-names to not download the wrong one.)
What to test:
I would be particularly interested in linux performance. We had some issues with Nvidia gpu on nixos + wayland. If you also experience issues, then try one of these three environment variables and tell us which one worked the best:
WEBKIT_DISABLE_COMPOSITING_MODE=1
WEBKIT_DISABLE_DMABUF_RENDERER=1
__NV_DISABLE_EXPLICIT_SYNC=1
Conclusion and credits
I wasn’t alone in this porting endeavour, big thanks to @WofWca, @nicodh, @Septias and @nojisan for their help on this.
Also thanks to @dotlambda for working on the nix package.
I’m also writing a blogpost on this topic, which I aim to publish next week. In the meantime you can read my other two blogposts about the steps that made this possible:
