👉 cssharp.icegame.ro is a free online compiler for CounterStrikeSharp (CS2) plugins.

Upload your plugin project as a .zip, pick the CounterStrikeSharp.API version, and download the compiled plugin. No local .NET SDK or Visual Studio required.

Why this exists

CounterStrikeSharp plugins are full C# projects, not a single file like .sma or .sp used by AMX Mod X or SourceMod. This compiler handles the whole workflow in the browser: unpacking the project, restoring NuGet packages, building it against the API version you choose, and handing you the result.

Features

Project-based workflow

• Upload a .zip with your full project: the .csproj plus all .cs files
• Built-in code editor to adjust .cs and .csproj files before compiling
• Compiled plugin is downloaded as a .zip, ready for your server
• NuGet packages used by the project are restored automatically

CounterStrikeSharp.API versions

• Choose the API version to build against, with search for older versions
• If your plugin targets a different .NET framework or API version, the compiler detects the mismatch and suggests the right version automatically
• Build configuration: Release for live servers, Debug for local troubleshooting only

Isolated builds

• Dependencies are fetched in an isolated sandbox
• The actual compilation runs in a separate container with no network access, away from the server files
• Compilation queue and per-IP rate limit keep the service stable for everyone

Interface

• 16 languages: English, Romanian, Italian, Hungarian, Serbian, Bulgarian, German, French, Russian, Turkish, Portuguese, Hindi, Spanish, Arabic, Japanese, Chinese
• Dark and light mode, responsive layout, usable on mobile
• Compilation statistics by framework and by API version
• Navbar button to switch between the CounterStrikeSharp, SourceMod and AMX Mod X compilers

Built-in guides (16 languages)

• Metamod and CounterStrikeSharp setup, your first Hello World plugin, becoming admin, commands and chat, game events, plugin config, NuGet and databases
• Troubleshooting: plugin not loading, compile errors explained, version mismatches, missing project references

How to use it

1. Go to cssharp.icegame.ro and pick your interface language.
2. Select the CounterStrikeSharp.API version. Not sure which one? Use the latest.
3. Upload your project as a .zip (it must contain the .csproj), or edit the files in the built-in editor.
4. Choose the build configuration and press Compile Now.
5. If the build succeeds, press Download to get the compiled plugin as a .zip.

To check which CounterStrikeSharp version your server is running, type meta list in the server console.

Good to know

• The archive must contain the full project, not just loose .cs files. The .csproj is required for the build.
• If your plugin references another project (for example a git submodule), GitHub's "Download ZIP" does not include the submodule contents. Add that folder to the archive yourself. The guides explain how to fix this.
