Jackett works as a proxy server: it translates queries from apps ([Sonarr](https://github.com/Sonarr/Sonarr), [Radarr](https://github.com/Radarr/Radarr), [SickRage](https://sickrage.github.io/), [CouchPotato](https://couchpota.to/), [Mylar](https://github.com/evilhero/mylar), [DuckieTV](https://github.com/SchizoDuckie/DuckieTV), etc) into tracker-site-specific http queries, parses the html response, then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic - removing the burden from other apps.
Developer note: The software implements the [Torznab](https://github.com/Sonarr/Sonarr/wiki/Implementing-a-Torznab-indexer) (with [nZEDb](https://github.com/nZEDb/nZEDb/blob/dev/docs/newznab_api_specification.txt) category numbering) and [TorrentPotato](https://github.com/RuudBurger/CouchPotatoServer/wiki/Couchpotato-torrent-provider) APIs.
* Windows using .NET 4.5.2 [Download here](https://www.microsoft.com/net/framework/versions/net452).
* Linux and macOS using Mono 4.6.0 and above. [Download here](http://www.mono-project.com/download/). Earlier versions of mono may work but some trackers may fail to negotiate SSL correctly, and others may cause Jackett to crash when used.
Trackers marked with [![(invite needed)][inviteneeded]](#) have no active maintainer and are missing features or are broken. If you have an invite for them please send it to kaso1717 -at- gmail.com to get them fixed/improved.
We recommend you install Jackett as a Windows service using the supplied installer. You may also download the zipped version if you would like to configure everything manually.
To get started with using the installer for Jackett, follow the steps below:
1. Download the latest version of the Windows installer, "Jackett.Installer.Windows.exe" from the [releases](https://github.com/Jackett/Jackett/releases/latest) page.
2. When prompted if you would like this app to make changes to your computer, select "yes".
3. If you would like to install Jackett as a Windows Service, make sure the "Install as Windows Service" checkbox is filled.
4. Once the installation has finished, check the "Launch Jackett" box to get started.
5. Navigate your web browser to: http://127.0.0.1:9117
6. You're now ready to begin adding your trackers and using Jackett.
When installed as a service the tray icon acts as a way to open/start/stop Jackett. If you opted to not install it as a service then Jackett will run its web server from the tray tool.
Jackett can also be run from the command line if you would like to see log messages (Ensure the server isn't already running from the tray/service). This can be done by using "JackettConsole.exe" (for Command Prompt), found in the Jackett data folder: "%ProgramData%\Jackett".
1. Install [Mono 4.6](http://www.mono-project.com/download/#download-lin) or better (using the latest stable release for your distribution is recommended)
* For other distros see the [Curl docs](http://curl.haxx.se/dlwiz/?type=devel).
3. Download and extract the latest `Jackett.Binaries.Mono.tar.gz` release from the [releases page](https://github.com/Jackett/Jackett/releases) and run Jackett using mono with the command `mono --debug JackettConsole.exe`.
Detailed instructions for [Ubuntu 14.x](http://www.htpcguides.com/install-jackett-on-ubuntu-14-x-for-custom-torrents-in-sonarr/) and [Ubuntu 15.x](http://www.htpcguides.com/install-jackett-ubuntu-15-x-for-custom-torrents-in-sonarr/)
If you want to run it with a user without a /home directory you need to add `Environment=XDG_CONFIG_HOME=/path/to/folder` to your systemd file, this folder will be used to store your config files.
The service will start on each logon. You can always stop it by running `launchctl unload ~/Library/LaunchAgents/org.user.Jackett.plist` from Terminal. You can start it again it using `launchctl load ~/Library/LaunchAgents/org.user.Jackett.plist`.
Logs are stored as usual under `~/.config/Jackett/log.txt`.
### Run without installing as a service
Download and extract the latest `Jackett.Binaries.Mono.tar.gz` release from the [releases page](https://github.com/Jackett/Jackett/releases) and run Jackett using mono with the command `mono --debug JackettConsole.exe`.
Detailed instructions are available at [LinuxServer.io Jackett Docker](https://hub.docker.com/r/linuxserver/jackett/). The Jackett Docker is highly recommended, especially if you are having Mono stability issues or having issues running Mono on your system eg. QNAP, Synology. Thanks to [LinuxServer.io](https://linuxserver.io)
When running jackett behind a reverse proxy make sure that the original hostname of the request is passed to Jackett. If HTTPS is used also set the X-Forwarded-Proto header to "https". Don't forget to adjust the "Base Path Override" Jackett option accordingly.
Please supply as much information about the problem you are experiencing as possible. Your issue has a much greater chance of being resolved if logs are supplied so that we can see what is going on. Creating an issue with '### isn't working' doesn't help anyone to fix the problem.
All contributions are welcome just send a pull request. Jackett's framework allows our team (and any other volunteering dev) to implement new trackers in an hour or two. If you'd like support for a new tracker but are not a developer then feel free to leave a request on the [issues page](https://github.com/Jackett/Jackett/issues). It is recommended to use Visual Studio 2017 when making code changes in this project. You can download the community version for free [here](https://www.visualstudio.com/downloads/).
