GDevelop — Build Games Without Coding Using Visual Event Logic

Introduction

GDevelop, created by Florian Rival, is the modern "no-code" game creator. Instead of writing scripts, you describe behavior via events — structured condition-action rules that compile to JavaScript. This turns programming into a visual, discoverable activity while remaining powerful enough for commercial games.

With over 22,000 GitHub stars, GDevelop is used by hobbyists, game jams, schools, and commercial indies. Games ship to iOS/Android app stores, Steam, itch.io, and the web. The GDevelop team has moved aggressively into Web-first: the editor runs in a browser with cloud storage.

What GDevelop Does

Scenes contain objects (sprites, text, tiled maps, UI). Events define behavior: "When [player collides with enemy] → [subtract 1 from player.HP] → [play sound]". Behaviors (Platformer, Physics, Pathfinding, Top-Down Movement, Tween) provide ready-made components. Extensions (JSON files) add shareable logic. Export to every platform in one click.

[Project file (JSON-based)]
   scenes, objects, events, resources, extensions
      |
[Game Engine (PixiJS + custom runtime)]
   events compile to JS, run in browser / Cordova / Electron

   iOS IPA (Cordova), Electron desktop, Steam-ready

Self-Hosting & Configuration

# Sample event (pseudo-notation)

Conditions:
  - Player is colliding with Enemy
  - Variable "invulnerable" of Player is equal to false
Actions:
  - Subtract 1 from Player.Variable("HP")
  - Change variable "invulnerable" of Player to true
  - Execute "make-invulnerable-flash" subevent
  - Play sound "hit.wav" at volume 80

Subevent: make-invulnerable-flash
  - Tween Player.Opacity between 0 and 1 over 1500ms
  - After 1.5s, set Player.Variable("invulnerable") = false

# Exporting an Android build (headless CLI, GDevelop Pro feature)
gdevelop-cli export --platform android-apk ./MyGame
# Outputs a signed APK ready for Play Store

# Deploy web build to any static host (itch.io, Netlify)
gdevelop-cli export --platform web ./MyGame --out ./dist
# Drag ./dist to itch.io or push to Netlify

FAQ

Q: GDevelop vs Construct 3? A: Both use event-based logic. GDevelop is open source + local-installable; Construct 3 is web-first, subscription-based. Commercial games shipped by both. For freedom + cost, GDevelop.

Q: Is it really no-code? A: For 95% of typical games, yes. For the remaining 5% (complex AI, advanced graphics), you can drop down to JavaScript via the Event Editor's "expression" and "JavaScript code" actions.

Q: Can I make money with GDevelop games? A: Yes — the MIT-licensed runtime has no royalties. GDevelop Pro ($5-10/mo) adds cloud exports, CI, in-game leaderboards. Free tier is sufficient for most projects.

Q: Performance? A: Games compile to PixiJS-backed WebGL, which is fast for 2D. 60 FPS with thousands of sprites is routine. For huge projects (10k+ entities), optimize events or drop to JS for hot paths.
