How to Install Plugins on an Impostor Among Us Server

Impostor supports plugins, which let you extend the server with new behaviour without changing the core program.

Where plugins go

Impostor loads plugin files from a plugins folder next to the server. Plugins are normally .NET library files with a .dll extension. If the folder does not exist, create it from the Files tab.

Install steps

1. Download the plugin from its official release page.
2. Check which Impostor version it supports. Plugins built for older versions may not work.
3. Stop the server.
4. Upload the .dll file into the plugins folder.
5. Start the server and watch the Console for a message showing the plugin loaded.

Configuration

Some plugins have their own settings or ask for entries in config.json. Read the plugin's readme for exact instructions, and do not guess at setting names.

Common problems

• Plugin not loading: the file is in the wrong folder, or it was built for a different Impostor version.
• Errors on startup: check the Console for a message naming the plugin.
• Server will not start: remove the most recent plugin and try again.

Safety

Plugins run inside your server, so only use ones from sources you trust. Read what they do before installing. Avoid random files from unknown sites.

Tips

• Add one plugin at a time so you can find what broke.
• Keep a backup of the plugins folder.
• Update plugins when you update Impostor.
• Ask in the community for the plugin's author if something needs support.

If you need help, share the Console output in a Discord ticket.
