For game jam organisers
Free online features for every game in your jam
Running a game jam? Every entrant can use BackendGen.dev Advanced free for the length of your jam: player sign-in, leaderboards, cloud saves and more, generated for Unity, Godot, Unreal and web games. It costs you and your entrants nothing.
- Free for every entrant
- Advanced, for the whole jam
- Top 3 games win a licence
- Unity, Godot, Unreal and web
For every entrant
A free Advanced pass, open from your jam's first day to its last. They generate and download as many backends as they like, and keep everything they download.
🏆 For your top 3
The top 3 games win a permanent Advanced licence each, with free updates for all of 1.x. Just tell us the winners when your results are out.
What entrants can add to their games
- Player sign-inA gamertag per player, tied to their device. No passwords for players.
- LeaderboardsDaily, weekly and all-time boards, ranked by the server.
- Cloud savesA save slot per player that follows them between sessions.
- Matchmaking and lobbiesQueues, parties and realtime rooms for multiplayer entries.
- Saved player dataProfiles, progress and unlocks, with rules so players only change their own.
- Runs on a laptopThe database is built in: no cloud account and no Docker, so it works at in-person jams with no internet.
Entrants use it in the browser at BackendGen.dev, with ready-made clients for Unity, Godot 4, Unreal Engine 5 and JavaScript. Using it is entirely optional: your jam's rules stay yours.

Questions
Does it cost the jam or the entrants anything?
No. The pass is free for every entrant, the prizes are free, and there's nothing for the jam to pay or sign.
What happens when the jam ends?
Entrants keep everything they downloaded: the backends run on their own PC or server and never check a licence. Their account goes back to trying the generator for free. The top 3 games get a permanent Advanced licence with free 1.x updates.
Which engines does it work with?
The generator makes ready-to-use clients for Unity, Godot 4, Unreal Engine 5 and JavaScript (web games). Any other engine that can make HTTP requests can use the backend's documented API.
Can everyone on a team use it?
Yes. Each team member can claim the pass with their own free account, and everyone can use the code it makes.
Do web games on itch.io work?
Yes. Players of a web build reach the backend over HTTPS, so entrants put it on a small server for the jam and voting weeks. The deploy guide takes about 20 minutes, and Star Raiders is a jam-sized example running on one.
