Free WebGL Game Hosting — Upload a Unity or Godot Build, Get an Instant Playable Link
Yes — you can host a WebGL game for free on The Gaming Nest. Upload the build folder from Unity, Godot, Three.js or Babylon.js (any folder with an `index.html` at its root) and you get back a link that plays instantly in the browser — no download, no install, no approval queue. The free tier gives every account 300 MB of hosting, keeps 10 build versions per project, and serves every file from a global CDN. Upload from the browser, or with one command from the CLI: `tgn deploy ./Builds/WebGL`.
Upload the build
Your Unity or Godot folder as-is — from the browser or one command.
Get an instant link
A shareable, embeddable play link. No download, no install.
A real quota
A hard per-account ceiling — so the hosting still exists next year.
Why free game hosting keeps disappearing — and why this is built differently
In April 2025 the best-known free WebGL host in this category went offline, after repeated upload abuse and denial-of-service attacks turned uncapped storage and bandwidth into a cloud bill no free service could absorb. Free hosting without a hard per-account ceiling is not a business model — it is an open invoice.
Our answer is deliberately boring: every account has a byte quota (300 MB free), and every upload is measured against it before a single byte is written. Archives are capped at 1,000 files and 1 GB extracted, and executables (.exe, .dll, .bat …) are rejected outright. Builds are served from object storage behind a CDN, so a traffic spike is absorbed at the edge instead of billed at the origin.
How to publish a WebGL build on The Gaming Nest
Two paths, same result. Take the command line if you deploy often, or the browser if you upload once.
From the CLI (5 steps)
- 1
Create an API key
On /profile/api-keys click "New key" and grant the deploy scopes: webgl:upload, webgl:deploy, webgl:read, project:read. The plaintext key (format tgn_k1_…) is shown exactly once — copy it immediately.
- 2
Log the CLI in
The CLI validates the key against the server straight away, so a wrong or revoked key fails in milliseconds instead of mid-upload.
tgn auth login tgn_k1_xxxxxxxx - 3
Pick your project
List the projects you own and copy the UUID — or pin it inside the build folder with a .tgnconfig.json so you never retype it.
tgn projects list tgn init --project <project-id> - 4
Deploy the build
One command runs five steps: package the folder, initialize hosting, request a signed upload ticket (valid 15 minutes), upload straight to storage, then extract and activate server-side. Adding --precompress Brotli-compresses eligible files and cuts the payload 3–5×.
tgn deploy ./Builds/WebGL --precompress - 5
Publish and share the link
Flip Publish on the project's manage screen — the player mounts on your public project page and the link becomes shareable and embeddable.
tgn open
From the browser (5 steps)
- 1
Create a project
Any project you own can host one WebGL build.
- 2
Open the WebGL screen
Go to /projects/manage/{projectId}/webgl — your consumed quota is shown as a bar at the top.
- 3
Initialize hosting and upload
Pick the entry point (defaults to index.html) and drop in your build's .zip. The archive limit is 500 MB.
- 4
Activate the version
Once extraction finishes the version goes Ready. Activate it in one click — and roll back to the previous one just as easily, up to 10 versions.
- 5
Hit Publish
The player mounts on your public project page and any visitor can play in-browser instantly.

Frequently asked questions
Is WebGL game hosting free?
+
Yes. Every account on The Gaming Nest gets 300 MB of WebGL hosting for free — no credit card, no trial period. The free tier includes CDN delivery, 10 retained versions per project, and one-click rollback. If you need more room, one-off paid tiers raise the quota, or you can submit a custom-quota request.
How do I host a Unity WebGL build?
+
Build your Unity project for the WebGL platform — you get a folder containing index.html and a Build/ subdirectory. Upload that folder as-is: either with tgn deploy ./Builds/WebGL from the CLI, or as a .zip on the /projects/manage/{projectId}/webgl screen. Activate it, hit Publish, and you have a live play link. You don't need to modify the Unity template or run a server.
Can I embed my game in another website?
+
Yes. Builds are served from a separate storage domain, so you can drop them into an iframe on any page you control with sandbox and allow="autoplay; fullscreen". Because the origin differs, the game is isolated from your parent page's cookies, localStorage and DOM. There is no exclusivity — the same build can still be published anywhere else.
Does it work with Godot, Three.js or Unreal?
+
Any engine that exports a static folder with an index.html at the root works: Unity, Godot, Three.js and Babylon.js are all supported. Unreal Engine removed its official HTML5 export back in 2019, so in practice there is usually no WebGL build to upload. Server-side scripting (Node, Python) is not supported — builds are static, client-side bundles only.
What's the file size limit?
+
The free quota is 300 MB per account. A single upload archive can be up to 500 MB, and after extraction it may contain at most 1,000 files totalling 1 GB. Executables (.exe, .dll, .bat and friends) are rejected — static web assets only.
What happens to my old builds?
+
Up to 10 versions are kept per project. You can activate any Ready version instantly without re-uploading, or roll back one step with a single command. Versions beyond the cap are cleaned up automatically within 24 hours, but stay listed in your version history for audit.
Do you take a revenue share or ask for exclusivity?
+
No. Hosting takes no cut of your revenue and asks for no exclusivity. Your game is yours: ship it on itch.io, Steam or your own site at the same time. Hosting on The Gaming Nest adds an instant play link and a discoverable project page — it doesn't replace your other channels.
Ship your game in minutes
300 MB of free hosting on every account — no credit card, no approval, no exclusivity.
