Show HN: Mastodon desktop client, made with Claude, using Rust and GTK4

A Linux desktop Mastodon client called FediGoo, written in Rust with GTK 4 and built using Claude Code by AI Sloperator, was posted to Hacker News' Show HN. FediGoo supports multiple accounts with OAuth login, home, local, federated, hashtag, list, trending, bookmark and favourite timelines, live updates over the streaming API, polls, filters and an image viewer, and builds with only the gtk4 and soup3 crate dependencies after installing pkgconf, libgtk-4-dev and libsoup-3.0-dev. The project ships with no license, and its accounts, access tokens and preferences are stored in ~/.config/fedigoo/config.json with owner-only permissions.

A Mastodon client for the Linux desktop, written in Rust with GTK 4. Created by AI Sloperator https://www.aisloperator.com/ with Claude Code. No license is given. - Multiple accounts, with OAuth login, switching and logout which revokes the token - Timelines: home, local, federated, hashtags, lists, trending posts, bookmarks and favourites - Notifications, mentions and private conversations - Live updates over the streaming API, with an unread badge and a "new items" button - Posts: content warnings, sensitive-media covers, image viewer with alt text, link cards right-click to open the link or copy it, also as Markdown , polls with voting , threads with indented replies, translation - Actions: reply, boost, favourite, bookmark, edit, delete, delete & re-draft, pin, mute conversation, copy link or text, report - Composer: character counter using the instance limit, content warning, visibility, language, media upload file picker or paste with alt text, polls, and Ctrl+Enter to send; if the server is slow or down, it shows that and you can cancel or try again without losing the post - Profiles: bio, verified fields, follow or follow request, notify on new posts, hide boosts, mute, block, domain block, list membership, followers and following - Search for accounts, hashtags and posts URLs from other servers are resolved - Explore trending posts, hashtags and news , followed hashtags, follow requests, list management, mutes and blocks, profile editing including avatar and header - Keyword and hashtag filters: view, add, edit and delete them; matching posts are collapsed behind a warning or hidden, as each filter says - Links to profiles, posts and hashtags on any server open inside the app - The sidebar can shrink to icons only the button at its foot , with labels as tooltips | Key | Action | |---|---| | Ctrl+N | New post | | F5 / Ctrl+R | Refresh | | Alt+Left / Esc / Backspace | Back | | Ctrl+F | Search | | Ctrl+Enter | Send post | | Ctrl+Q | Quit | | PgDn / Space | Page down | | PgUp / Shift+Space | Page up | Paging lands on the start of a post where that doesn't skip anything, and pages through posts taller than the window. Paging up twice at the top of a feed checks for new posts; paging twice past either end of a thread checks for new replies. Space and Backspace still type in text fields, and Backspace does nothing on a top-level page there's nothing to go back to . In the image viewer: | Key or gesture | Action | |---|---| | Right / Space, or click the image | Next image | | Left / Backspace, or click its left 20% | Previous image | | Swipe or drag left / right | Next / previous | | Esc / Ctrl+W | Close | System packages Debian/Ubuntu names : sudo apt install pkgconf libgtk-4-dev libsoup-3.0-dev Then, with a stable Rust toolchain from rustup: cargo build --release ./target/release/fedigoo The only crate dependencies are the GTK bindings gtk4 and the libsoup bindings soup3 plus their own dependencies. JSON handling and the HTML conversion are built in. HTTPS uses libsoup and glib-networking. fedigoo GTK picks the backend honours GDK BACKEND fedigoo --x11 force X11 fedigoo --wayland force Wayland ./target/release/fedigoo --install This copies the executable to ~/.local/bin/fedigoo , and adds a menu entry ~/.local/share/applications/com.aisloperator.FediGoo.desktop and an icon under ~/.local/share/icons/hicolor/ , so FediGoo shows up in your application menu and dock. fedigoo --uninstall removes those files and leaves your accounts and settings alone. Log in through the welcome screen. FediGoo opens your instance's authorisation page in the browser; paste the code it shows back into FediGoo. All local data accounts, access tokens, OAuth client registrations, preferences is in $XDG CONFIG HOME/fedigoo/config.json , normally ~/.config/fedigoo/config.json . The file is created with owner-only permissions. cargo test offline unit tests cargo test -- --ignored also hits the public mastodon.social API For testing the UI without a display, GTK's Broadway backend works, and tools/broadway-input.py sends it real pointer and keyboard input clicks, drags, key shortcuts in place of a web browser. Its docstring has the details. This section is updated before each release, from a build on the reference system: Debian 13 trixie on amd64 x86 64 , using Debian's own packages for GTK 4, libsoup 3 and the other system libraries. How much of it is specific to the reference system differs by list: - Direct crates come from Cargo.toml , so they are the same everywhere. - Indirect crates come from the committed Cargo.lock , listed for an x86 64 Linux build. A build from the same lock file uses the same crate versions on any system, though another target may build a slightly different set of crates. A cargo update can change the versions. - Non-crate libraries both lists are what the reference system's release binary links to and loads. Another distribution, distribution version or architecture may have other library versions or sonames, link a different set, or load other modules at run time. These are the dependencies in Cargo.toml , with their version requirements. gtk4 is imported under the name gtk , and soup3 under the name soup . These are the system libraries that the release binary links to directly, as reported by objdump -p on the reference system. Through the crate bindings, the app's code also calls Pango and GDK, which are loaded as part of GTK. Building also needs the pkg-config and glib-compile-resources tools and the GTK 4 and libsoup 3 development files Debian: pkgconf libgtk-4-dev libsoup-3.0-dev . - libc GNU C Library - libgcc s - libgio-2.0 GIO - libglib-2.0 GLib - libgobject-2.0 GObject - libgraphene-1.0 Graphene - libgtk-4 GTK 4 - libsoup-3.0 libsoup 3 These are every other crate in the build normal and build-time dependencies as resolved in Cargo.lock for x86 64 Linux at the time of this update, from cargo tree -e normal,build . Where a crate appears in more than one version, all versions are listed. A later cargo update within the same Cargo.toml requirements may resolve different versions, which might bring in different crates. Some of these such as system-deps , pkg-config , syn and toml are used only while compiling and are not part of the binary. - autocfg https://crates.io/crates/autocfg 1.5.1 - bitflags https://crates.io/crates/bitflags 2.13.2 - cairo-rs https://crates.io/crates/cairo-rs 0.22.9 - cairo-sys-rs https://crates.io/crates/cairo-sys-rs 0.22.9 - cfg-expr https://crates.io/crates/cfg-expr 0.20.10 - equivalent https://crates.io/crates/equivalent 1.0.3 - field-offset https://crates.io/crates/field-offset 0.3.6 - futures-channel https://crates.io/crates/futures-channel 0.3.34 - futures-core https://crates.io/crates/futures-core 0.3.34 - futures-executor https://crates.io/crates/futures-executor 0.3.34 - futures-io https://crates.io/crates/futures-io 0.3.34 - futures-macro https://crates.io/crates/futures-macro 0.3.34 - futures-task https://crates.io/crates/futures-task 0.3.34 - futures-util https://crates.io/crates/futures-util 0.3.34 - gdk-pixbuf https://crates.io/crates/gdk-pixbuf 0.22.0 - gdk-pixbuf-sys https://crates.io/crates/gdk-pixbuf-sys 0.22.9 - gdk4 https://crates.io/crates/gdk4 0.11.5 - gdk4-sys https://crates.io/crates/gdk4-sys 0.11.5 - gio https://crates.io/crates/gio 0.22.10 - gio-sys https://crates.io/crates/gio-sys 0.22.9 - glib https://crates.io/crates/glib 0.22.10 - glib-macros https://crates.io/crates/glib-macros 0.22.9 - glib-sys https://crates.io/crates/glib-sys 0.22.9 - gobject-sys https://crates.io/crates/gobject-sys 0.22.9 - graphene-rs https://crates.io/crates/graphene-rs 0.22.8 - graphene-sys https://crates.io/crates/graphene-sys 0.22.9 - gsk4 https://crates.io/crates/gsk4 0.11.5 - gsk4-sys https://crates.io/crates/gsk4-sys 0.11.5 - gtk4-macros https://crates.io/crates/gtk4-macros 0.11.5 - gtk4-sys https://crates.io/crates/gtk4-sys 0.11.5 - hashbrown https://crates.io/crates/hashbrown 0.17.1 - heck https://crates.io/crates/heck 0.5.0 - indexmap https://crates.io/crates/indexmap 2.14.2 - libc https://crates.io/crates/libc 0.2.191 - memchr https://crates.io/crates/memchr 2.8.3 - memoffset https://crates.io/crates/memoffset 0.9.1 - pango https://crates.io/crates/pango 0.22.9 - pango-sys https://crates.io/crates/pango-sys 0.22.9 - pin-project-lite https://crates.io/crates/pin-project-lite 0.2.17 - pkg-config https://crates.io/crates/pkg-config 0.3.34 - proc-macro-crate https://crates.io/crates/proc-macro-crate 3.5.0 - proc-macro2 https://crates.io/crates/proc-macro2 1.0.107 - quote https://crates.io/crates/quote 1.0.47 - rustc version https://crates.io/crates/rustc version 0.4.1 - semver https://crates.io/crates/semver 1.0.28 - serde spanned https://crates.io/crates/serde spanned 1.1.2 - slab https://crates.io/crates/slab 0.4.12 - smallvec https://crates.io/crates/smallvec 1.16.4 - soup3-sys https://crates.io/crates/soup3-sys 0.9.0 - syn https://crates.io/crates/syn 3.0.9 - system-deps https://crates.io/crates/system-deps 7.0.8 , 9.0.1 - target-lexicon https://crates.io/crates/target-lexicon 0.13.5 - toml https://crates.io/crates/toml 1.1.8+spec-1.1.0 - toml datetime https://crates.io/crates/toml datetime 1.1.2+spec-1.1.0 - toml edit https://crates.io/crates/toml edit 0.25.17+spec-1.1.0 - toml parser https://crates.io/crates/toml parser 1.1.5+spec-1.1.0 - unicode-ident https://crates.io/crates/unicode-ident 1.0.27 - version-compare https://crates.io/crates/version-compare 0.2.1 - winnow https://crates.io/crates/winnow 1.0.4 These are the libraries loaded because of the direct ones above, as reported by ldd for the release binary on the reference system, plus modules that GLib and GTK load at run time, which ldd doesn't show.
