How your apps connect

A download client is no use until something tells it what to fetch. This page is the plain list of which of your apps Cresdock introduces to each other on its own, which ones need something only you have, and how to tell the two apart before you buy anything.

Reading time: ~4 minutes ยท Applies to: every Cresdock plan, including the free one

1.What connected means here

Most panels install apps. The part that eats an evening is what comes after: opening each app in turn, finding where it keeps the details of the others, and copying them across without a typo.

Cresdock does that part for the pairs it can. Install two apps that belong together, in whichever order suits you, and they find each other — the second one to arrive is introduced to the first, not just the other way round. It happens again by itself after an update, after a rebuild, and after you reset an app back to a clean start, so a workspace that was connected in March is still connected in September.

Nothing to switch on. There is no wiring step, no setup wizard for it and no toggle to find. Connections happen as part of installing, on every plan, and are checked again each time an app starts.

2.What connects itself

These are made for you the moment both apps exist in your workspace:

Install both……and this is already done
Sonarr, Radarr or Lidarr + qBittorrent, Deluge, Transmission or SABnzbdNew episodes, films and albums are handed over to fetch, then filed away once they arrive.
Prowlarr + any of those clientsAnything you pick straight out of Prowlarr's own search goes to your client.
Prowlarr + Sonarr, Radarr or LidarrProwlarr keeps their list of search sites up to date, so you only manage it in one place.
Sonarr, Radarr or Lidarr + Jackett or NZBHydra2They search the sites you have set up there, without being pointed at them.
Prowlarr or Jackett + FlareSolverrSites that put a check in front of every visitor are answered for you.
Bazarr + Sonarr or RadarrBazarr watches what they have and fetches subtitles for it.
Recyclarr + Sonarr or RadarrQuality settings are kept in step with the community guides.
Unpackerr + Sonarr, Radarr or LidarrAnything arriving packed up is opened, so they can file it away.
cross-seed + qBittorrent, Deluge or TransmissionMatches are added straight to your client, without fetching any of it a second time.
cross-seed + JackettIt looks for those matches on the sites you have set up there.
Order doesn't matter. Install the client first and the library apps find it later; install them first and the client is picked up when it arrives. You never have to plan the sequence.

3.What stays yours to do

The rest of the list needs something no panel can hold on your behalf: an account, a sign-in, or a key that only exists after you have made it. We would rather name those plainly than let you find them on a Sunday evening.

ConnectionWhy it's yours
Sonarr, Radarr or Lidarr telling Plex, Jellyfin or Emby that something landedPlex signs in with your own account. Jellyfin and Emby need a key made inside them, after you have created your account there on first open — so there is none to hand over beforehand.
Overseerr and JellyseerrTheir opening setup is the sign-in to your media server, and that sign-in is yours. Everything after it, including where Sonarr and Radarr are, follows on inside their own wizard.
TautulliIt asks for your Plex account before it will watch anything.
autobrrIts filters live in its own store, and the key that opens that store is made inside autobrr after you create an account there — so there is none to use in advance.
Your tracker and usenet accountsThey're your accounts with those sites. Cresdock keeps the app ready for them and stays out of the rest.
Subtitle and cloud-storage sign-insSame reason: they're yours, and only you can agree to them.
You are not left to guess. For every one of these, your panel spells out what the pair is for, which app to open, and the exact details to copy — including which address to use, because the one in your browser's bar leads to the sign-in page and is the usual reason a connection looks made and never works.

4.The two apps we don't connect

Two apps in the catalogue are genuinely not connected for you today, and it would be easy to leave that off a marketing page:

  • ruTorrent — Sonarr, Radarr, Lidarr, Prowlarr and cross-seed are all connected to the other download clients and not to this one. Adding it is yours to do, inside each of those apps. If you'd rather none of that was hand-work, pick qBittorrent, Deluge or Transmission.
  • Mylar — its download client and search sites are set up inside Mylar itself, the way they would be on any install. The comics side simply hasn't caught up with the film and television side yet.
If you route an app through a VPN, some pairings can't work at all. The panel says so in as many words rather than printing an address that would look right, report itself connected, and quietly never import anything.

5.Apps that meet in your folders

A good number of apps need no introduction at all, because they already share the same folders. One app fills a folder, another reads it — that is the connection, and there is nothing to set up on either side.

  • Albums Lidarr files away turn up in Navidrome, because it plays that same music folder.
  • Audiobookshelf, Kavita, Komga and Calibre-Web read the books, comics and audiobooks already sitting in your media folders. Add a library pointing at the folder and your collection is there — no pairing step, and no second copy.
  • File Browser, the web shell, FTPS and code-server open the very same folders your other apps use, so a file you move in one is moved for all of them.
  • Syncthing keeps folders on your own devices in step with folders here, and can drop new files where Paperless-ngx will find them.
  • Duplicati takes copies of what your apps keep for themselves, on a schedule. Your downloads and media are far too large for that, and stay where they are.
One set of folders, not one per app. That's also why nothing here needs a path to be translated between apps — the folder Sonarr sees is the folder your download client sees, which is the folder your media server streams from.

6.Apps that stand on their own

Some apps have nobody to be introduced to, and saying so is more useful than implying otherwise. WireGuard and OpenVPN, AdGuard Home, DuckDNS, SmokePing, Speedtest, LibreSpeed, FreshRSS, Miniflux, Solidtime, Tududi and The Lounge each do their own job and share nothing with your other apps.

Where two of them overlap — WireGuard and OpenVPN, FreshRSS and Miniflux, File Browser and File Browser Quantum — each app's own page says so, so you keep one rather than discovering the duplication later.

7.Seeing it for yourself

Every app tile in your panel has a Connection details view. It lists every app in your workspace that one belongs with, what each pairing is for in a sentence, and whether the panel has already made it:

  • Already made — no instructions, because there is nothing for you to do.
  • Yours to make — which app to open, what it will ask for, and the details to copy.
  • Can't be made — said plainly, with the reason, and no address offered that wouldn't work.

That view is generated from the same list the panel works from, so it can't drift into telling you an app is connected when it isn't. If a connection ever fails to take — an app still waking up is the usual cause — the panel says which pair, and tries again on its own.

The tile carries more than connection details — every app also shows a plain working-or-trouble verdict, with alerts and a live log behind it. That side of the panel has a page of its own.

8.What it costs

Nothing extra, on any plan. Every app in the catalogue is included, and so is every connection on this page. Cresdock is priced on how many people use it and how many machines you run it on — never on which apps you install, and never per connection.

The free tier is a real tier rather than a trial: one user, permanent, no card, and the same catalogue and the same wiring as everything else.

Try it on your own server. One command installs the panel on any Ubuntu or Debian machine — start free at cresdock.com, install two apps that belong together, and watch them find each other.
