CCAI : Cloudron Custom App Installer

[timconsidine]

Update 20/01/2026 :

• I am deprecating installation of the open version of CCAI, as I don't really see that anyone would want to host their own open version.
  It's still available, but you will have to hunt for it or ask me.
  Basically I've removed it from the catalogue.

• I've updated CCAI-P which is the preferred self-host app.
  Runs on your own instance, credentials are stored in the app on your server

• timeouts removed from CCAI-P : you're logged in or you're not : logout button for security, but you can leave it running if it's only you have access to it

• added 3 new descriptors :

  • packageAuthor : previously implied, now explicit
  • appNote : extended explanation of the catalogue entry
  • appHomepage : clickable link to the app's Homepage so you can read about it

• it will take a little while for me to populate the new fields for all apps, but will get on with it.

@staff : can I modify the AppWishlist to the effect :

• please DO NOT add CCAI to the AppStore
• please DO add CCAI-P to the AppStore
• or please make your own version (which I am sure will be more lovely)

There are clear pain points in installing custom apps.
This is eminently resolvable.
The problem is without an official way to get CCAI-P, users still have to go through those pain points. Maybe only once, but that's enough to deter them.

The growing catalogue of custom apps (and there are many more that I am not aware of) shows that relying on the App Store only, and relying on approval of items into the App Store, is a clear bottle neck to maximum use and efficiency of a user's Cloudron instance.

EDIT : at the risk of over-selling the point, can Cloudron staff imagine this ? A daily workload where they never ever have to think about adding apps to the Cloudron AppStore, unless they really want to. No more user pressure.

Not in a million years would I have been able to install a custom app on my own. CCAI-P makes it stupidly easy. Thank you Tim!

[timconsidine]

@humptydumpty and I am working on another non-Cloudron way to get over the blockage of getting CCAI-P into the AppStore. One simple download.

But ssssh, don’t tell anyone yet

[Announce] CustomAppGateway (CAG) – Solving the "Chicken & Egg" for Custom Apps

Hi everyone,

I'm excited to share a new project that I hope will be a valuable addition to our ecosystem: CustomAppGateway (CAG).

Available now at CAG Website

The "Chicken & Egg" Problem

For a while now, I've been working on CCAI and then CCAI-P (Cloudron Custom App Installer - Personal), a tool designed to be the primary "Install UI" for custom apps. It empowers you to easily install packaged custom apps that aren't yet in the official store.

However, there is a catch-22: How do you install the installer (CCAI-P) without using the CLI ?

Enter CustomAppGateway (CAG)

CustomAppGateway is the solution to that problem. It is a specialized, lightweight run-once tool designed solely to deploy CCAI-P to your Cloudron instance securely and easily.

It provides three simple methods:

1. CAG Online (Hosted): A web-based installer that runs securely in your browser (using a proxy to handle CORS, with tokens processed in memory only).
2. CAG Web (self-hosted) : same as above but made easy to deploy to your own server.
3. CAG App (Downloaded): A standalone terminal executable for Mac, Windows, and Linux for those who prefer a local utility.

AppStore Independence

CAG and CCAI-P are about AppStore Independence. You are not reliant on waiting for an app to be officially adopted or packaged by the Cloudron team to use it, if you need it NOW.

That said, the Cloudron App Store remains vital. It provides the seamless, tested update mechanism we all rely on. While custom apps give us freedom and immediacy, the App Store is still the gold standard for long-term maintenance and stability.

Updates & Housekeeping

• CCAI-P is now the primary interface for installing custom apps and will receive further updates and improvements.
• The old CCAI open hosted version is effectively deprecated and will be archived/deleted. I encourage everyone to switch to using CCAI-P.

Security

A hot topic which I’ve taken seriously.
CAG leverages the excellent security baked into the Cloudron platform.
We focus on :

• using a dedicated one-time token which you create and subsequently delete
• restricting the token to use only on your IP address
  The footprint for attack is tiny.

A Note to the Cloudron Team

I want to extend a huge and ongoing thank you to the Cloudron team for their continued, tireless efforts. Cloudron remains the #1 self-hosting platform because of your hard work.

We know you face time and effort constraints with a small team. My hope is that CustomAppGateway and CCAI-P can ease your burden a little by empowering the community to self-service their custom app needs, allowing you to focus on the core platform and official apps.

Where to get it

CAG Website

Status

• hosted installer : zero setup : tested
• web installer : private setup : tested
• desktop installer : minimal setup : tested on MacOS
• TODO :
  • test desktop installer on Windows
  • test desktop installer on Linux

Feedback is always welcome!
And in doing so, please cut me some slack - it's a ground-breaking project, and as such may have some gremlins for a short (hopefully) while.

[timconsidine]

House-keeping :

• Cloudron have announced they will introduce support "in-platform" for custom app deployments
• consequently CCAI (the open hosted-as-a-service version) can no longer be installed from CCAI. (It can be installed manually if really needed but I don't really see why anyone would want to).
• CCAI-P (the personal edition which stores auth creds locally in app) can no longer be installed from CCAI : if you want CCAI-P, use the new https://customappgateway.appx.uk distribution point
• CCAI-P has been cleaned of legacy auth timeouts (inherited from original CCAI) so runtime gremlins should not occur. There is still a manual logout and connect option, in case the user wants to do so manually. Otherwise it should remain 'ready to go' without timeouts.

Improvements :

• both CCAI and CCAI-P still focus on new installations, and there is no support for updating an existing custom app. I am working on introducing support for updates.

The Future :

• with Cloudron's announcement that their v9.1 release will include some support for in-platform deployment of custom apps, "the writing is clearly on the wall" and CCAI / CCAI-P / CustomAppGateway will die and git repos / docker images will be removed at some point.
• I doubt anyone is more pleased than me !
• however we do not know the timescales for Cloudron 9.1 (other big stuff in it too), so I will continue to make available CCAI / CCAI-P until some point after Cloudron 9.1 is stable.

[girish]

@timconsidine I left a note at https://forum.cloudron.io/topic/14976/what-s-coming-in-9.1/11 about how we plan to implement this. I don't have a timeline for 9.1 but given the build up all your apps, we are trying to get this out asap!

[timconsidine]

@girish thank you - very helpful - still digesting it.

Hoping to get my final "end of life" changes done today, which can allow CCAI-P to limp on until Cloudron in-platform functionality is tested, then turn the CCAI and CAG websites into digital tombstones.

No need for any rush - always happy for you to take your time to do a proper job (unlike my hashed together PoC).

[LoudLemur]

@timconsidine The gui on your new customappgateway.appx.uk is gorgeous!

[humptydumpty]

deleted my old ccai app and used the new bash thing. I logged in via SSH and typed the command there. It's been going for... 20 mins now? How long is it supposed to take?

Restarted the server and tried the Windows installer instead. It worked perfectly without the https:// part for the cloudron domain link.

@timconsidine new ccai-p is installed now but it won't sync the new library. I entered the token + link in the config and restarted the app. I re-logged in ccai-p as well. No dice.

here's the error log when trying to install an app. hth.

[timconsidine]

@humptydumpty sorry about your experience - heavy updates and and changed locations - mid-process of going live - almost done now - you might be running into the ecosystem update process.

I will update you when finished. Hopefully not long now

[timconsidine]

Attempting to be concise, I have completed changes to the CCAI environment.

CCAI

1. original "hosted-as-a-service" ccai.appx.uk is now disabled and now a placeholder to avoid broken forum links
2. new "entry point" is customappgateway.appx.uk

CustomAppGateway

1. previously just an installer for CCAI-P, via browser or binary
2. deliberate web UI change to create distance from old system/concept

3. no more browser-based installations involving submission of creds in a browser
4. only supported deploy route is an installer script using a binary (Mac, Linux, Windows as needed), which cleans up by removing the binary on completion
5. now can install not just CCAI-P but other custom apps
6. custom apps master catalogue now lives in customappgateway
7. recommended to install CCAI-P and then install apps from there to enable updates
8. but there is also an option to install a single custom app from customappgateway, for those who don't want CCAI-P and don't care about updates
9. I re-factored the installer binary to be available for use by others - driven by run-time arguments, no custom app meta-data baked into the installer : see customappgateway.appx.uk Advanced section

CCAI-P

1. CCAI-P now supports updates to installed custom apps ... providing they were installed using the new CCAI-P version (uses local 'installed.json' to know what to check)
2. Master App Catalogue now maintained (only) by me - I will attempt to keep populated & updated, but let me know if something needs adding or changing - happy to do so
3. CCAI-P now supports a Local Catalogue, maintainable by you ! Independence, privacy, experimentation - whatever !

4. CCAI-P app update checking and processing is not fully checked (I haven't got any apps to update and I haven't invested time in faking a test). Let me know if any issues. Will try to do some real or fake testing.

Given Cloudron 9.1 upcoming support for custom apps, I am not planning any further major changes, just fixing any reported issues.

[timconsidine]

@humptydumpty I finished the upgrade !
Apologies again that you got caught up in the middle of it

[humptydumpty]

@timconsidine I can't help with code, but more than happy to help with testing!

• I reinstalled CCAI-P via the Windows.exe installer and that went smoothly.
• I reinstalled Zoneminder via the new CCAI-P and that also went smoothly.
• Attempted to install Excalidraw but that didn't work (I logged out in CCAI, restarted app, and clicked on start-over). Here's the log from the CCAI page.
