# Glitchless for game jams

> In a game jam? Glitchless is free for jam teams until January 31, 2027: 50,000 play sessions a month, room for a team of five and 90 days of data, with code JAM26. Any jam, any engine.

## Jams running now

JAM26 works for every one of them, and for any jam not listed here.

- **Official Unity Game Jam** (Nov 5–14, 2026, Unity): add the Unity package before your first build. A WebGL build on itch.io sends from your players' browsers. [Unity setup](https://www.glitchless.gg/unity.md)
- **Epic AI MegaJam** (Nov 12–15, 2026, Unreal): jam builds are Development builds, so turn on Send in Development builds, and declare Glitchless as set up before the jam. Code MEGAJAM26 works too. [The MegaJam guide](https://github.com/glitchless-gg/glitchless/blob/main/docs/jam/megajam-2026.md)
- **GitHub Game Off** (Nov 1 – Dec 1, 2026, any engine): a month to make a game in the open. Playtest every week, and put a read-only board in your README. [The jam on itch.io](https://itch.io/jam/game-off-2026)
- **OpenGame jam** (Nov 18 – Dec 18, 2026, web): a month of browser games. Measure your builds while you make them: games played on opengame.io itself can't reach Glitchless yet. [Web setup](https://www.glitchless.gg/threejs.md)
- **Any other jam**: Ludum Dare, a Godot Wild Jam, your studio's own. Hosting one? A jam room puts every team's game on one screen: https://jam.glitchless.gg

## What you get during a jam

- **See why your build stutters.** Every hitch comes with its likely cause: a shader compile, garbage collection, a scene load, a burst of new objects.
- **Playtesters press F8.** They send a note and a screenshot. Your agent reads it with the session behind it.
- **Show the judges.** Share a read-only board pinned to jam week on your game's page or in your dev log.

## Set it up in minutes

1. Sign up with code JAM26.
2. Paste the [setup prompt](https://github.com/glitchless-gg/glitchless/blob/main/docs/agent-setup-prompt.md) into your coding agent. It adds Glitchless to your game and makes its dashboard.
3. After every playtest, ask your agent "What's wrong with my game?" and let it fix the next build.

It works with Unity, Godot, Unreal and Three.js, and with GameMaker, Roblox, Phaser, Babylon.js and PlayCanvas.

## Your submission's tool declaration

Many jams ask what you made or set up before the jam started. Paste this into your submission and edit it to match what you did:

```text
Set up before the jam: Glitchless (glitchless.gg), a third-party observability tool for games (MIT licence, github.com/glitchless-gg/glitchless). It records frame times, errors, crashes and bug reports from our builds, and its MCP server (glitchless-mcp) lets our coding agent read them. Before the jam started we only installed it, set it up and connected it to our agent; all game code, prompts and assets were made during the jam.
```

## A dev log outline

```text
# [Game name]: how we built it

## The team and the tools
Who we are, the agents and MCP servers we used, and what we set up before the jam.

## Day by day
What we built each day, and the prompts and decisions that mattered.

## A problem our playtesters hit
A stutter, a crash, a level people quit on. The data: [share link, pinned to jam week]

## What the agent found and changed
The finding it read, the change it made, and what we fixed by hand.

## Did the fix work?
Before and after: frame times, or the crash-free rate on the first day against the last. [share link]

## What we'd do differently
```

Make each share link from a board: Share, then Fixed dates covering your jam, and an expiry of Never. Judges see jam week whenever they open it, with no player IDs or stack traces.

## When it ends

The jam tier ends January 31, 2027, 23:59 UTC. Your workspace goes back to the Free plan's limits (5,000 play sessions a month, one person, 14 days of data), and nothing is deleted.
