About Deadlock Mod Manager

A free, open-source mod management tool built by the community, for the community — making it simple to install, organize, and update mods for Valve’s Deadlock.

What Is Deadlock Mod Manager?

Deadlock Mod Manager (DLMM) is a dedicated desktop application for managing mods in Valve’s hero shooter, Deadlock. Rather than manually copying files into game directories and hoping nothing breaks, DLMM gives players a clean interface to browse, install, toggle, and update mods with a few clicks.

The tool connects directly to GameBanana, the primary mod repository for Deadlock, so you can discover and download mods without leaving the app. It handles file placement, conflict detection, and version tracking automatically.

DLMM runs on Windows and Linux, and is distributed under the GNU GPL v3.0 license — meaning anyone can use, modify, and contribute to it freely.

Development History

DLMM grew out of the Deadlock modding community’s need for a proper management tool. Here is how the project has evolved:

Early Development
Stormix, the project’s creator, began building a mod manager after noticing that Deadlock modders were manually juggling VPK files and folder structures. The first builds focused on basic install and uninstall functionality.
GameBanana Integration
A major milestone came with direct GameBanana API integration, allowing users to browse, search, and download mods from within the app itself — no browser required.
Community Growth
The project attracted contributors from the broader Deadlock community. Bug reports, feature requests, and pull requests on GitHub helped shape the tool into something far more polished than a solo effort could produce.
Ongoing Development
Active development continues on GitHub, with regular releases addressing compatibility with Deadlock updates, new mod formats, and user-requested features.

The Team

Stormix created and maintains Deadlock Mod Manager. The project is open source, hosted on GitHub, and accepts contributions from anyone interested in improving the tool.

Beyond the core maintainer, DLMM benefits from a growing group of contributors who submit bug fixes, test new releases, translate the interface, and suggest features. The Deadlock modding community on Discord and Reddit also plays a significant role in shaping the tool’s direction through feedback and testing.

If you want to contribute — whether through code, documentation, or bug reports — the GitHub repository is the place to start.

Open Source Commitment

Deadlock Mod Manager is released under the GNU General Public License v3.0. This means:

  • The full source code is publicly available and auditable
  • Anyone can fork, modify, and redistribute the software
  • Derivative works must also remain open source under the same license
  • There are no hidden telemetry, paywalls, or locked features

The project’s transparency is one of its biggest strengths. Users can verify exactly what the software does, and developers can contribute improvements that benefit everyone.
