The Honkers Railway Launcher on Linux: Flathub first, community packages second

A GTK4 shell pinned to one SDK tag in Cargo.toml

The launcher is a Rust program, and the dependency list in `Cargo.toml` describes the whole stack in a dozen lines. The package is named `honkers-railway-launcher` at version `1.15.3`, built on edition 2021 with a `build.rs` script and `publish = false`, which is why there is no crate to pull from a registry.

[package]
name = "honkers-railway-launcher"
version = "1.15.3"
description = "The Honkers Railway launcher"

The interface is GTK4 with libadwaita, driven by relm4, and the build depends on `glib-build-tools` for the resource compilation that `build.rs` performs. Around that sit `rfd` for native file dialogs through the xdg portal, `open` for handing URLs to the desktop, `whatadistro` for distribution detection, `serde_json` for the `config.json` the launcher reads, `cached` for memoised values, `md-5` for checksums, and `human-panic` plus `tracing` for crash output and logging.

The part that matters most is the SDK, and it is pinned to a git tag rather than a version range:

[dependencies.anime-launcher-sdk]
git = "https://github.com/an-anime-team/anime-launcher-sdk"
tag = "1.36.11"
features = ["all", "star-rail", "star-rail-patch"]

Two of those three features are the whole product. The `star-rail` feature is the game client, and `star-rail-patch` is the patching path, which the repository description summarises as automatic patching and telemetry disabling. Because the SDK is a tagged git dependency, a new game version that needs SDK work means a new tag, a new build, and a new package published by whoever maintains the channel you use. The release profile strips symbols and turns on link time optimisation, so the shipped binary is small but gives you little to debug with.

Localisation is done with Fluent. `fluentscan.py` sits at the repository root, `fluent-templates` and `unic-langid` are dependencies, and the `assets/` directory holds the resources the binary loads at runtime.

Nobody official publishes the packages, so Flathub is the real front door

The download section says it plainly: the launcher developer does not provide packages for the program, and the project relies almost entirely on other people to maintain them. Installation instructions live in the project wiki, and the same paragraph warns that those instructions may be outdated for lack of interest in keeping them current. That is the first thing a new user should internalise, because the wiki is the only install documentation and it is community maintained.

Two packages are called officially supported by the An Anime Team. The Flatpak is published on Flathub as `moe.launcher.the-honkers-railway-launcher` and is described as working on any distribution, with Fedora, Pop!_OS and SteamOS or Steam Deck named as examples. The RPM comes from an openSUSE build service repository, covers Fedora and openSUSE, and carries a warning that these packages are often really outdated and are not recommended to use.

Community support is a different tier. An AUR package named `the-honkers-railway-launcher-bin` covers Arch Linux, Manjaro and EndeavourOS, a NixOS module is maintained as `aagl-gtk-on-nix`, and a Gentoo ebuild lives in `aagl-ebuilds`. The project keeps contact with those maintainers. Below that sits a third party tier the project does not verify at all: a DEB on Launchpad for Ubuntu, Linux Mint and Pop!_OS, and a Pacstall package for Ubuntu. The distinction matters when something breaks, because the project states it is not related to the state of those packages.

So the practical order is Flathub first, AUR or Nix second, and the Launchpad DEB last. A macOS launcher from the same ecosystem is credited as containing additional compatibility components.

The components index in config.json is where China breaks the launcher

One failure mode is documented in unusual detail, and it is worth reading before anything else because it silently breaks the launcher rather than throwing an error.

The launcher supports a Chinese edition of the game, enabled automatically when the system language is `zh_cn` and otherwise changeable in the launcher settings. The problem is that GitHub is blocked in China, and the launcher uses GitHub in more than one place. The components index that other users rely on is simply not reachable, so a Chinese user cannot share the same index as everybody else.

The workaround is documented and concrete. Make your own copy of the components repository, change every link in it from GitHub releases to some mirror, and then point the launcher at your copy by updating the components index repo link in the launcher's `config.json` file. That is a fork, a link rewrite and a config edit, and it has to be redone whenever the upstream components change and the mirror falls behind.

The `config.json` file itself is worth noting for another reason: the project parses it with `serde_json`, which is the same crate that reads the per-game configuration, so a malformed edit surfaces as a parse failure rather than a silent fallback.

Maintenance mode, feature complete, and a universal launcher on the horizon

The project status section is unusually blunt. The project is in maintenance mode and is considered feature complete. It will continue to receive updates with bugfixes and support for new versions of the game, and contributors are said to help keep it alive by keeping up with latest game changes. The author says they are working on other projects, and that the future is in uniting all the launchers into a single universal launcher, `anime-games-launcher`. This project stays in what is called a proof of concept stage and requires major changes, which again require interest from the author's side.

That is a plan, not a schedule. The realistic reading for a user is that new features here are unlikely, while compatibility fixes for new game patches continue to arrive from contributors.

The release history supports that reading. Version 1.15.1 was published on 2026-06-02, 1.15.2 on 2026-06-30, and 1.15.3 on 2026-09-11. The last push to the repository was on 2026-09-28. The licence is GPL-3.0, with the text in the `LICENSE` file at the root, and the default branch is `main`. The project is not archived, and the author points at the Discord server as the place where all of the project's life happens, with a Zulip instance and a wiki linked from the README as secondary destinations. A `CHANGELOG.md` file carries the chronology of the project.

Per-game launcher now, universal launcher later, macOS build for compatibility

There is a real alternative here, and it is a question of scope rather than of technology.

The first alternative is the per-game launcher this project already is, versus the planned universal launcher that the author says should eventually absorb all of them. A universal launcher would hold several games behind one UI, one update path and one set of preferences. The cost of waiting for it is that the current per-game project is in proof of concept stage and needs major changes that depend on the author's interest, so a team that plans to run several of these games has no guarantee of when one codebase would exist.

The second alternative is a different distribution channel for the same launcher, and the choice here has real consequences. The Flatpak from Flathub is officially supported and works across distributions, but it sandboxes the application, which changes how the launcher reaches the game's own files and the system. The AUR and Nix packages run natively and stay closer to the host system, at the cost of being maintained by people whose time you do not control. The README already says the RPM route should be avoided, and the DEB and Pacstall packages come from third parties whose state the project explicitly does not verify.

The third alternative is platform. A separate macOS launcher from the same ecosystem is credited in the README as containing additional compatibility components, so anyone on macOS is pointed at a different codebase rather than at this one.

Where this launcher is the wrong choice

The honest constraints are visible in the repository rather than hidden in an issue tracker.

Documentation is the first problem. The installation guides live in the wiki, the project warns they may be outdated, and it asks other people to keep them current. A new user therefore starts with a wiki page that may describe an obsolete package name or an obsolete Flatpak application id, and the fix is a pull request to the wiki rather than a command.

Packaging is the second problem. There is no first party build. The officially supported Flatpak is maintained by a person outside the core team, the AUR and Nix packages by community members, and the DEB and Pacstall packages by parties the project does not check. When a game update arrives, whether your channel receives a working package depends on someone else's release, and the project has already documented that the RPM channel is often outdated.

Third, the SDK is pinned to the tag `1.36.11`. A new game version that needs work in the SDK produces a new tag, and every downstream package has to be rebuilt against it. The project expects that to happen and describes contributor work as exactly this kind of update, so it is a managed friction rather than a defect, but it does mean the launcher is never independent of the game it launches.

Fourth, the Chinese configuration path is a fork-and-mirror workflow, which is a poor fit for a shared or managed machine. And fifth, for anything beyond launching one game, a per-game launcher is the wrong shape, since the author is already moving toward a single universal launcher.

Editorial conclusion

Adopt this launcher if you play Honkers Railway on Linux and accept a community-run project that the author describes as feature complete: install the Flatpak from Flathub rather than the RPM or the third party DEB, and expect the wiki installation guides to need correction. Do not adopt it if you need a supported channel for a work machine, a Chinese network where GitHub is blocked without a mirrored components index, or a launcher that is not tied to a single game. Before switching, check that the Flathub build matches the game version you need, confirm the components index link in `config.json` points at a mirror you control, and read the changelog, because the last push was on 2026-09-28 and the next release may only carry bugfixes.
