PatchKit gets your content distributed in no time

PatchKit is a Game Distribution Service (Content Distribution Service for games). It’s a system that allows you to distribute your game to players efficiently. You don’t need to learn anything new in particular to get your game published, all you need to do is those three steps:

  1. Set up an account
  2. Upload the game
  3. Click the publish button

These steps are enough to distribute your game to multiple servers all over the world along with delta files.

Forget about patching

PatchKit speeds up your development and release process by fully-automated version & delta building and file distribution mechanism. You don’t longer need to worry about creating and managing patch files by yourself. Just build your game using your game engine of choice and upload the result to PatchKit servers through the website. From there, our system takes care of everything else.

Upload your game’s content to PatchKit to publish your game. Your files will be processed and transferred around before delivering them to the players:

  1. Your game content is stored on our Storage Server.
  2. It is sent to Version Processing Severs to build a distributable version file and delta file.
  3. Version file and delta file are stored back on Storage Server.
  4. When published, version file and delta file are distributed to multiple distribution nodes.
  5. The players can now download those files.
  6. Launcher applies downloaded version file to the local file system, and now your new game version is ready to be played!

Game Launcher

With Game Launcher your players will be able to download, validate and play your game without a hustle. The launcher is an internal part of your game; it does not require a separate installation procedure or user registration.


  • Game downloading
  • Delta-based game upgrading
  • Files repairing
  • High-speed P2P + HTTP data transfers
  • Self-upgradable
  • Fully-customizable
  • Windows, OSX and Linux versions

The launcher will quickly download and install the game. It will make sure it is up-to-date on each run and if not, sync and apply the patch on locally installed content. If game content gets corrupted, it allows to verify it and re-download corrupted content.

If a new version of the launcher is released, it will upgrade itself to the newest release. It’s fault-tolerant mechanism, so even if you accidentally publish a launcher version that is not starting, it will still upgrade itself if a new version is released.

Build integration at reach

Connect PatchKit to your continuous integration server with Command-Line Tools and Unity Integration plugin (Coming Soon!). Save your time and publish your game version fast at any time with a single click. Your release will be built, uploaded, processed and distributed over our CDN network in minutes.

Don’t risk breaking your game! Our system validates your version content each time a new version is uploaded. If there’s something wrong with it, your new version file will be rejected, and you will be notified about possible errors and how to solve them.

Optional DRM

PatchKit does not enforce any particular DRM on your game. Instead, you’re free to use any DRM of your choice, or even make your game completely DRM-free!

You can generate any number of license keys and sell or give them away to your players. A valid license key enables to download and upgrade your product reasonable number of times. An overused key is automatically blocked to prevent the spread of possible illegally re-distributed license keys.

On top of that, PatchKit allows deep integration via PatchKit API to prevent the game from running if a license key cannot be validated.


The PatchKit team takes security matters very seriously. The infrastructure is strongly backed up by industry-proven Amazon Web Services with the auto-scaling feature set up to meet even the highest possible demand. Client’s game data is stored on encrypted S3 volumes. Distributed version files are custom-format, AES-encrypted data files.

There’s not a single point of failure - in the worst possible case when central PatchKit API servers go down, players will still be able to download and play their games due to the non-centralized character of PatchKit service. By default game files are downloaded using private P2P network and mirrors are discovered without a need for a centralized server. Game information is distributed to mirror nodes as well.

PatchKit supports a variety of game engines.

It’s not limited to the above game engines only. If you’re working on a game engine that is not listed here or if your game is built on a custom-made game engine, you can still use PatchKit with all its features. If you encounter any issues, please contact us.
