Glitchless docs
Most of the time your coding agent reads these for you: paste the setup prompt and it does the rest. They're here for when you want to know how something works.
Start here
The setup prompt
Paste it into Claude Code, Codex, Cursor or any agent. It adds Glitchless to your game, connects the MCP server and builds a dashboard.
Glitchless Cloud
Sign in with Google or GitHub. Get started gives you the same prompt with your project's keys. Free for 5,000 play sessions a month.
Run it yourself
One Docker container, or
npm run server: the server, the dashboard and a file store, no other services.
Engines
Unreal Engine
The C++ plugin for UE 5.7 and 5.8: settings, Blueprint nodes, crashes,
-glitchless-measureand Unreal MCP.Unity
The package for 2022.3 LTS and Unity 6: setup, what it measures in each build type, bug reports.
Godot
The addon for Godot 4.5 and later: autoload, hitch causes, errors, phones.
Web games
One npm package for Three.js, Phaser, Babylon.js and PlayCanvas, with WebMCP and an overlay.
GameMaker
GML scripts for GameMaker 2024.2 and later, as a local package or installed by a script.
Coding agents
MCP server
npx -y glitchless-mcp: 16 tools for findings, frame times, errors, death hotspots, bug reports, versions and playtests.Claude Code plugin and skills
The instrument, dashboard, triage and Steam Deck skills, which any agent can also read as plain files.
WebMCP
Tools a running web game gives your agent: measure frames, inspect the scene, take a screenshot.
Playtest bots
glitchless-playtestplays fixed-seed runs and compares a change with a saved baseline.Steam Deck
glitchless-decksends a build to a Deck on your network, starts it and measures it there.
Features
Dashboards and boards
Every game's own pages, which your agent designs from the events the game sends.
Bug reports
F8 or your own button: the player's note, a screenshot and the moments before it.
Share links
One board, read only and signed out, optionally pinned to fixed dates, for dev logs and publishers.
Source maps
A CLI and a Vite plugin, so a minified web build's errors show the original file and line.
Alerts
New errors, crash-free drops, frame-time regressions and new findings, to Discord, Slack or email.
Datadog and OpenTelemetry
Send the same metrics and logs on to Datadog or any OpenTelemetry backend.
Privacy modes and retention
Anonymous by default; install mode adds a random player ID for D1, D7 and D30 retention.
Reference
Technical spec
Every event and field, the query API, how the numbers are computed, keys and storage.
Wire format
What an SDK sends to
/v1/intake, for writing your own.What the SDKs send
Every field in each privacy mode, with lines to adapt for your game's privacy policy.
Releases
The Unreal plugin and GameMaker package downloads, and what changed in each.
