How do you install nightly builds?

[abitrolly]

I see there is a scheduled workflow that builds and upload nightlies to AWS S3 https://github.com/janhq/jan/blob/main/.github/workflows/jan-tauri-build-nightly.yaml But I haven't found any instructions how to download and install them (and keep updated).

I want to use my fix #7894 which is a blocker, but there is no fresh release including it yet.

The nightly index is:

https://delta.jan.ai/nightly/latest.json

That is the file the nightly workflow publishes after a scheduled/manual build, and it contains the current platform-specific download URLs.

As of my check, it points to 0.7.9-4030 with pub_date 2026-04-20T21:00:33.539Z, for example:

• Linux x64 AppImage: https://delta.jan.ai/nightly/Jan-nightly_0.7.9-4030_amd64.AppImage
• Windows x64 installer: https://delta.jan.ai/nightly/Jan-nightly_0.7.9-4030_x64-setup.exe
• macOS app tarball: https://delta.jan.ai/nightly/Jan-nightly_0.7.9-4030.app.tar.gz

The workflow schedule is 20:00 UTC on Monday, Tuesday, and Wednesday, and scheduled runs publish to the AWS S3-backed nightly/ path. I would treat latest.json as the authoritative moving pointer and download the URL for your platform from there.

Now I can read the build workflow more clearly. )

This is also https://apps-nightly.jan.ai/update-check that returns the same JSON.
