# Plain Craft Launcher (PCL): a Visual Basic .NET Minecraft launcher with a public source mirror

> PCL is a free Minecraft launcher whose repository publishes most of its source, including the UI library, animation module, download module and launch module. The code is synced at release time, not continuously, so the repository trails the shipped build.

## What PCL solves, and who actually needs it

Minecraft launchers exist because the official launcher is not the only way to start the game, and PCL is one of the alternatives. The README describes it as Plain Craft Launcher and points to https://meloong.com/pcl for the free official build. The repository is not the product. It is a source mirror: the README states that it contains most of PCL's source code, including the UI library, the animation module, the download module and the Minecraft launch module, and that the code is not updated in real time but synchronised once with each PCL release.

That single sentence defines the audience. This repository is for people who want to read how a launcher works, or who want to inspect a module such as the download or launch path, without expecting to track day-to-day development. It is not a contribution-first project in the usual sense. The README thanks the community for its support, and the repository links to a feature-voting discussion where the developer says higher-voted items are handled first, which is an unusual channel: feature direction is steered through GitHub Discussions rather than through pull requests against a live tree.

The launcher itself is written in Visual Basic .NET, and the repository layout matches that: a solution file named Plain Craft Launcher 2.sln, a project directory of the same name, and a separate PCLCS directory. Anyone who has only used launchers written in Java or Electron will find the stack unfamiliar, but for a Windows desktop application it is a coherent choice, and it explains why the UI library and animation module are shipped as part of the same tree.

## How the source tree is organised, and why it lags the release

The top level of the repository contains the solution file, the main project folder, PCLCS, a MeloongCore folder, a patches folder, a 最新正式版.zip archive, a LICENCE file, and the usual dotfiles. The README's list of included modules (UI library, animation, download, launch) maps onto the main project rather than being split into separate packages, so reading the launcher means reading one large VB.NET application rather than assembling libraries.

The important architectural fact is the sync model. Because the README says code is synced once per release, the repository state does not correspond to the binary a user downloads at any given moment; it corresponds to the last release boundary. Release tags in the repository follow a four-part version scheme, with 2.13.1.1 published on 2026-08-06, 2.13.1.0 on 2026-08-01 and 2.13.0.1 on 2026-07-03. The last push to the repository was on 2026-09-03, which is consistent with a release-sync pattern rather than continuous commits.

The practical consequence is that you cannot diff the shipped executable against the repository with any confidence between releases. If you are evaluating PCL for security or for licence compliance, the repository gives you a snapshot of intent, not a reproducible build input. The presence of 最新正式版.zip at the top level reinforces this: the repository carries a copy of the latest official release archive alongside the source, which is convenient for a mirror but blurs the line between source and distribution.

## Getting PCL and starting a game: the documented path

The README does not give build instructions, and it does not tell you to clone the repository to use the launcher. It tells you where to download the official release: the PCL download page at https://meloong.com/pcl, described as the place to get the free official version. There is no documented build command in the README, no package restore step, and no stated .NET SDK version, so a reader who wants to compile from source has to work that out from the solution file and the project directory without guidance.

Because no install commands are documented, the honest first-use path is the download page, not a terminal. The repository does contain the solution file and the main project directory at its top level, so a reader who already has the .NET tooling can see the layout the README describes by opening the repository in their own environment. What you should find is the solution file at the repository root and the main project directory beside it. Anything beyond that, such as which target framework the project file declares or whether the solution builds cleanly, is not documented in the README and should be verified against the project files themselves rather than assumed.

For help after installation, the README points to a separate documentation repository, LTCatt/PCL2Help, which it calls the storage repository for PCL's built-in help documentation. That is the place to look for feature-level questions, not this repository.

## Where PCL is the wrong tool

The clearest limitation is platform. The README never mentions macOS or Linux, and the project is a Visual Basic .NET desktop application, which in practice means Windows. Search interest in "PCL Mac" and "PCL Launcher Mac" is real, but nothing in the repository or README supports a macOS build, and the documentation does not describe one. If you need a launcher on macOS, this is not it, and the repository gives you no path to port it.

The second limitation is the release-time sync. If your reason for visiting the repository is to verify that the binary you run matches the source, the README's own statement about synchronisation defeats that. You get a source snapshot per release, not a commit history you can trace to a specific build artifact. For most users this is irrelevant. For anyone doing a supply-chain review, it is the whole question, and the answer is that the repository is not designed to answer it.

The third is licensing clarity. The repository contains a file named LICENCE, but the project metadata reports the licence as NOASSERTION, meaning no standard licence was detected. The README does not explain the terms, and it does not state what you may do with the source. That is not a reason to avoid the launcher, but it is a reason to read the LICENCE file before you redistribute anything or reuse a module such as the UI library or animation code in your own project.

## What PCL is not: the alternative approach to compare against

The natural comparison is a launcher whose source repository is the development tree, where every commit is public and the binary is built from a tagged commit in that same history. PCL is the opposite arrangement: the binary is primary, the download page is the distribution channel, and the repository is a periodic mirror of the source behind it. If your requirement is a launcher you can build yourself from a pinned commit and audit end to end, PCL's model does not meet it, and you should choose a project that publishes continuous history instead.

The second comparison is the official Minecraft launcher. PCL's README positions it as a free alternative with its own UI library, animation module and download module, which is a different proposition from the official launcher's minimal shell. If all you want is to start the game, the official launcher requires no third-party download and no trust decision about a mirror. PCL's value shows up when you want the extra module behaviour the README lists, and that is a preference, not a defect in either tool.

The third comparison is with forks and derivative builds. The related searches include "PCL CE" and "PCL build", which suggests users encounter variants. The repository does not describe a CE edition or a separate build channel, so treat any such label as something to verify against its own source rather than assuming it is covered by this README.

## Maintenance, release cadence and upgrade cost

The last push to this repository was on 2026-09-03. The most recent release listed is 2.13.1.1 on 2026-08-06, following 2.13.1.0 on 2026-08-01 and 2.13.0.1 on 2026-07-03. That cadence, roughly one release per month with occasional patch bumps, is what the release list supports. The repository is not archived.

Upgrade cost is low for users and moderate for anyone tracking the source. Users replace the launcher with the build from the download page; the README does not document a rollback procedure, an update channel setting, or a way to pin an older version, so if you need to stay on a specific build you should keep the archive you downloaded. The repository does ship 最新正式版.zip at the top level, which is a copy of the latest official release archive, but the README does not describe it as a versioned archive of past releases.

For source readers, the cost is the sync model. Each release brings a batch of changes rather than a readable stream of small commits, so reviewing what changed between two versions means diffing two snapshots. That is workable but slower than reading a normal commit log, and it is the price of a mirror that is deliberately not updated in real time.

## Conclusion

PCL is worth adopting if you want a free launcher and you are comfortable with a Windows-oriented .NET application whose repository is a release-time mirror rather than a live development tree. It is the wrong choice if you need to audit the exact binary you run, if you want to build the launcher from the repository yourself, or if you are on macOS or Linux, which the README does not claim to support. Before you commit, verify three things: that the release you download matches the version tag in the repository, that the licence file at the repository root is acceptable to you (the repository is marked NOASSERTION, so the terms need reading rather than assuming), and that the help documentation at LTCatt/PCL2Help covers the feature you actually need, since the README itself is four short paragraphs.

## FAQ

### Where do I download PCL?

The README points to https://meloong.com/pcl, described as the page for downloading the free official version of PCL. The repository itself is a source mirror, not the distribution channel.

### Does PCL run on macOS?

Nothing in the README or repository layout indicates a macOS build. PCL is a Visual Basic .NET application with a Windows solution file, and the README does not mention macOS or Linux support.

### Is the code in the PCL repository the same as the released launcher?

The README states that the code is not updated in real time and is synchronised once with each PCL release. The repository therefore reflects the last release boundary rather than the current development state.

### What licence does PCL use?

The repository contains a file named LICENCE, but the project metadata reports the licence as NOASSERTION, meaning no standard licence was detected. The README does not explain the terms, so read the LICENCE file before redistributing or reusing any module.

### How do I request a new feature in PCL?

The README links to a feature-voting discussion on GitHub, where the developer says items with more votes are handled first. That discussion, not a pull request against the source tree, is the documented channel for feature requests.
