Servitor

A command-line Fediverse client that doesn’t require a server.

Features

  • Works with fediverse software such as Mastodon, Lemmy, PeerTube, and more
  • Doesn't require a server
  • Sidesteps defederation politics
    • because posts are always pulled directly from their source site, you are not affected by servers blocking each other
  • Keeps your subscriptions private
    • subscriptions are stored locally, so you can subscribe to people without sending them follow requests
  • Follows the Unix philosophy
    • the browser itself is just handles the ActivityPub protocol, media viewing is all handled by separate programs

Installation

  1. Run uname -ms and, based on the output, download the latest corresponding release.
  2. cd into the directory that servitor is in (e.g. cd ~/Downloads).
  3. Run mv servitor-version-arch-os servitor to rename the binary to servitor.
  4. Run chmod +x servitor to make it executable.
  5. Run ./servitor open @[email protected], for example, to try it out.
  6. Run mv servitor ~/.local/bin to allow it to be run from anywhere (might not work on some distributions).

I only test Linux x86_64 releases.

Usage

  • servitor open @[email protected] to open profiles.
  • servitor open https://example.org/user/username to open links.
  • servitor feed feed-name to open feeds (see below).

Configuration

The config file is located at ~/.config/servitor/config.toml.

[feeds]
# the entries will be spliced together
# in chronological order, like an RSS reader
linux = [ # open with `servitor feed linux`
    "@[email protected]",
    "@[email protected]",
    "@[email protected]",
]
dnd = [ # open with `servitor feed dnd`
    "@[email protected]",
    "@[email protected]",
]

[style.colors]
primary = "#A4f59b"
error = "#9c3535"
highlight = "#0d7d00"
code_background = "#4b4b4b"

[network]
preload_amount = 5 # the number of posts to load in above and below the highlighted post
timeout_seconds = 5
cache_size = 128 # the number of JSON responses the cache can hold

[media]
# described below

Media Hook

There are various ways to open files on Linux (xdg-open, mailcap, handlr, bespoke scripts, etc). The media.hook config option allows you to configure whichever one you use. The value is a list of strings that will be executed as a command. Parameters will be substituted as follows:

  • %url — substituted with the URL being opened
  • %mimetype — substituted with the media type being opened, e.g. image/png
  • %supertype — substituted with the first part of the media type, e.g. image
  • %subtype — substituted with the subtype, e.g. png

Here is a simple example config that opens videos and gifs in mpv, images in feh, and everything else in firefox:

[media]
hook = [
    "sh", "-c",
    '''
        if test "$2" = "video"; then exec mpv --keep-open=yes "$0"; fi
        if test "$1" = "image/gif"; then exec mpv --keep-open=yes "$0"; fi
        if test "$2" = "image"; then exec feh --scale-down --image-bg black "$0"; fi
        exec firefox "$0"
    ''',
    "%url", "%mimetype", "%supertype"
]

media.hook defaults to ["xdg-open", "%url"].

A Brief Overview of the Fediverse

For the purpose of this browser, the fediverse can be thought of as a collection of internet forums that use a shared protocol called ActivityPub. Instead of serving content over text/html, they serve their content over application/activity+json, which provides for higher-level semantics such as comment sections, retweets, etc.

Just like conventional forums, each site has a different moderation policy, and the administrators of each site have complete control over the moderation of that site. Unlike conventional internet forums, the fediverse allows users from one site to interact with (like, follow, comment on, etc) users and posts on another site, assuming the administrators of the both sites permit the interaction.
