How to Upload, Host, and Embed an HTML5 Game (Complete Guide for Indie Devs)

#gamedev #javascript #unity3d #godot

One of the biggest challenges for indie developers making HTML5 games is figuring out how to actually publish them online.

You finish the game… and then you realise:

  • You need hosting
  • You need a playable game page
  • You want players to share the game
  • You might want to embed it on other sites

This guide will show you how to upload, host, and embed an HTML5 game online.

Step 1: Export Your Game as HTML5

Most engines already support HTML5 exports.

Common engines that work well:

  • Unity WebGL
  • Phaser
  • Construct
  • Godot
  • Three.js projects

When exporting your game you will usually get something like:

index.html
game.js
assets/
Enter fullscreen mode Exit fullscreen mode

Your index.html file is the entry point that launches the game.

Step 2: Host the Game Files

To make your game playable online you need somewhere to host the files.

Options include:

  • Your own server
  • Static hosting (Netlify, GitHub Pages)
  • Game platforms

However many hosting services don’t handle large asset files or game distribution very well.

Platforms designed for HTML5 games often make this much easier.

Step 3: Upload the Game

Platforms like iDev.Games allow developers to upload their HTML5 builds directly.

This gives you:

  • free game hosting
  • a playable game page
  • player discovery
  • optional developer tools

Uploading usually takes just a few minutes.

Step 4: Embed the Game Anywhere

One of the best parts of HTML5 games is that they can be embedded anywhere using an iframe.

Example:

<iframe src="https://idev.games/embed/yourgame"
width="960"
height="600"
frameborder="0"></iframe>
Enter fullscreen mode Exit fullscreen mode

This allows your game to be played on:

  • blogs
  • forums
  • portfolio sites
  • other game portals

The same build can live across multiple sites while staying centrally updated.

Step 5: Add Game Features (Optional)

Once your game is online you may want to add features like:

  • leaderboards
  • cloud saves
  • multiplayer data
  • player accounts

Some platforms provide APIs that allow games to store player data without running your own backend.

Step 6: Monetize Your HTML5 Game

Monetization is one of the hardest parts of web games.

Traditional banner ads often hurt the player experience.

Alternative options include:

  • optional in-game purchases
  • cosmetic items
  • supporter packs
  • reward systems

These approaches work better for browser-based games where players expect quick and lightweight experiences.

Final Thoughts

Publishing HTML5 games online is easier than ever.

With modern browsers supporting powerful web technologies, developers can create games that run instantly across desktop and mobile.

The key steps are simple:

  1. Export your game as HTML5
  2. Upload the files to a hosting platform
  3. Embed and share the game anywhere

It’s a platform I built over the last 10 years specifically for indie HTML5 game developers.
