Patch every player from one upload
GGPatcher gives your game server its own Windows launcher, with your name, logo and colours. Upload files in the web panel, and every player's launcher downloads what changed, checks each file and starts the game.
Free for 3 days with 1 GB of storage. No card needed.
This is the launcher your players get. Type your server's name and pick a colour.
Pricing
One subscription is one launcher for one game server. Plans differ only in storage: every feature is in every plan.
Free trial
3 days with 1 GB of storage, no card needed. If you don't subscribe, the account and its files are deleted 7 days after the trial ends.

Card payments are handled by Stripe and renew every month until you cancel. Crypto payments are handled by NOWPayments: you pay 1, 3, 6, or 12 months in advance, and nothing renews by itself.
From your upload to their Play button
No publish step and no version number to raise. Upload, and the next time a player opens the launcher the update is there.
Upload
Drag changed files or whole folders into the panel. The folder structure is kept, and each file can be up to 1 GB.
Compare
When a player opens the launcher, it compares every game file with yours by SHA-256.
Download
Only the files that differ are downloaded, four at a time. A dropped connection is retried on its own.
Swap in
Every download is checked and set aside first, then all of them are swapped in together. If anything fails, the game folder stays as it was.

Launcher branding
Name, logo, background, icon and colours, or one of six ready-made themes; the window size, the text on the Play button, and a Config button that opens a second program. Launchers load the branding on every start, so a change reaches players without a new download.
Patch notes
News in five categories (update, hotfix, event, maintenance and feature), each with an optional version number. Players read them in the launcher, which also shows the newest one after an update that changed files.
Maintenance
Switch it on with a message, or schedule when it starts and ends. Launchers show your message and keep Play disabled.
Discord
Post to your Discord channel when files are uploaded, a patch note is published or maintenance is switched on.
Statistics
Unique players by IP address, completed and failed updates and bandwidth for the last 24 hours, 7 days or 30 days, the success rate of the last 30 days, and a chart of the last 14 days.
Your team
Admin accounts for your staff, and an audit log of every sign-in, upload and change.
What your players get
One file, nothing to install
A single Windows program in the game folder. It runs on Microsoft WebView2, which current versions of Windows already include.
Their language
English, Romanian, German, Polish or Turkish. The launcher opens in the player's Windows language (or English), and players switch with one click.
Repair
Checks every game file and downloads whatever is missing or damaged.
A launcher that updates itself
When a new launcher version comes out, it downloads it, checks it and restarts.

Questions
Questions about billing are answered on the pricing page.
Which games does it work with?
Windows games whose client runs from one folder. You choose the program the Play button starts.
How do my players get the launcher?
You download GGPatcher.zip from the panel, with your settings and icon already inside. Put GGPatcher.exe in your game client folder and hand the client to your players. Later changes to the branding reach them on the next start.
What do players need to run the launcher?
Windows 10 or 11, 32-bit or 64-bit, and one file, GGPatcher.exe, in the game folder. It runs on Microsoft WebView2, which Windows 11 and an up-to-date Windows 10 already include; if it is missing, the launcher offers to open Microsoft's download page. It starts in the player's Windows language, and they can switch it with one click.
Do I need my own server for the files?
No. GGPatcher stores your files and delivers them to your players.
How large can my files be?
Up to 1 GB per file, in whatever folders your client uses. How much you can store in total depends on your plan.
What do my players need?
A Windows PC with Microsoft WebView2, which current versions of Windows already include. If it is missing, the launcher says so and offers to open Microsoft's download page.
Can I change the look later?
Yes. Launchers load their branding every time they start, so a new name, logo, background, colours or links reach your players the next time they open the launcher, without a new download.
Try it with your own client
Create an account, upload your files and download your launcher. It takes a few minutes, and the first 3 days are free.
