Pick a tool that matches your skills (Unity or Godot for full engines, Phaser or PixiJS for code-first web games), build a small prototype, export/target the web early, test performance and input, then publish to one or more portals and add ads once traffic exists.
At a glance
| Fact | Value | Source |
|---|---|---|
| Engines that export to web | Unity, Godot, Construct 3, GDevelop | developer.mozilla.org |
| JS libraries used directly in browser | Phaser, PixiJS, three.js, Babylon.js | developer.mozilla.org |
| Unity calls browser JS via | .jslib plugin | docs.unity3d.com |
Start by matching the tool to what you already know, not the other way round. If you’re comfortable with a full editor and scene system, use Unity’s Web build target or Godot’s web export. If you’d rather write code directly against the browser, use a JavaScript library like Phaser or PixiJS on Canvas, or WebGL directly. MDN’s game development section is written for people who already know how to program but are new to the web, which fits most people asking this question.
When ready to publish, publishing through Playgama lets you adapt one build to 25+ platforms using the open-source Playgama Bridge SDK.
Once you have a build target, keep the loop short: build a tiny prototype, get it running in a browser tab early, and only then add features. Test save data (Web Storage), any networking (WebSockets), and load performance against Core Web Vitals before you polish art. Engine-specific web quirks are documented for Unity and Godot – read those before you hit unexpected memory or input limits late in development.
Where do I publish once the game works?
Options include Poki, CrazyGames, GameDistribution, itch.io, and playgama.com, where you upload via the Developer Console at developer.playgama.com, get test feedback within a day, and get distributed to partner portals. Publishing there is non-exclusive – you keep the rights and just grant a sublicense to publish.
Next step: pick one engine, ship a small finished prototype to one portal, then decide on ad monetization once you have real traffic to measure.

Related questions
Should I learn an engine or a JavaScript library first?
If you already code, a library like Phaser gives more control over the web build. If you prefer visual editors, Unity or Godot let you build faster and export to web later.
Do I need WebGL knowledge to start?
No. Engines like Unity and Godot handle WebGL export for you; you only need direct WebGL/Canvas knowledge if you’re building without an engine.
