App Store - one-click open-source apps on blitz.cloud

The 13 open-source apps you can install in one click on blitz.cloud, what each one needs, and which ones don't run on the platform yet.

The blitz.cloud App Store has 13 open-source apps you can install in one click: Nextcloud, Immich, Ghost, Vaultwarden, Jellyfin, Home Assistant, n8n, Uptime Kuma, FreshRSS, Syncthing, Linkding, Memos and Stirling PDF. Pick one, give it a name, and it installs with the settings, storage and database it needs.

We run every entry under the same rules a real install gets before we list it: sandboxed, no root, inside the memory limit. Some didn't pass, and we list those anyway with a sentence saying why, rather than hiding them.

Why some apps don't run yet

The store card says this before the install button, in the same words:

Nextcloud wants to set up its own files as the machine's owner when it first starts, which blitz.cloud does not allow any app to do. It may stop on startup until we ship an image that does not need it.
Immich also wants a Redis alongside its database, and blitz.cloud can only set up one database per app so far.
Home Assistant expects full run of the machine it is on, which blitz.cloud does not give an app. It could not see devices on your home network from here either way.
FreshRSS and Stirling PDF change system settings as the machine's owner when they start. We're looking for builds that don't need to.

All of these come down to one rule: no app on blitz.cloud runs as root. That rule is what makes it reasonable to run strangers' apps next to each other, so we'd rather find images that work within it than relax it.

How installing works

In the dashboard, open the App Store or click "Host something new" and choose "A ready-made app".
Search by what you want ("photos", "blog", "passwords") or browse the categories.
Pick a name for the app. It becomes the subdomain, like vault.<you>.blitz.cloud.
Click "Put it online".

The store entry brings the rest: the version, the port, the folders to keep, the settings the app reads, and a health check that knows what "working" looks like for that app. If the app needs a database, one is created and connected, and the settings it will fill in are listed before anything is applied.

Store apps are restarted automatically if they stop answering their health check. After install, the Environment tab shows every setting and lets you change it.

Storage and memory

Each app reserves the storage in the table from your plan's 10 GB, whether or not it fills it. Nextcloud plus its MariaDB takes 6 of the 10 GB, for example. Most apps use the small size (128 MB reserved, up to 512 MB). n8n uses medium (256 MB reserved, up to 1 GB). See limits for how that adds up.

Can I install an app that isn't in the store?

Yes, if there is a public Docker image for it on Docker Hub. See deploy a Docker image. The store is the list we have tested; the Docker path is for everything else.
