Fedimeister is not a standalone Mastodon client, yet. The current development focus lies on creating a supplement to the webclient, adding features and functionality, for creatives, that are missing there. Basic familiarity with the Fediverse is assumed.
Fedimeister is available for Linux, Windows and MacOS. A Java 8 (or later) runtime environment is required to run the application.
Fedimeister comes as a single executable file. No Installation (apart from the Java runtime environment) is required. Upon first start, the software will ask for the url of the account to connect to and then start an OAUTH flow that involves registering with that profile. Only the access token is stored locally.
Right click the jar and select ☰ Open from the popup menu. Confirm that you want to run the software. Your choice will be remembered for future launches.
The .jar file extension is not registered with the Java Runtime Environment. This often happens after installing a Zip Manager.
