HEUS HUB — Setup

One-time setup, all done by clicking in your browser — no command line. You'll create a small free Cloudflare Worker that safely holds your API keys, then paste two things into the hub.

⏱ about 5–10 minutes · everything here is free

Create a Worker

  1. In the left menu, click Workers & Pages.
  2. Click Create applicationCreate Worker.
  3. Name it heus-hub, then click Deploy. (It deploys a default "Hello World" — we replace it next.)

Paste the HEUS Worker code

  1. On the Worker page, click Edit code (top right).
  2. In the editor, select everything (Ctrl+A) and delete it.
  3. Click Copy all code below, paste it into the editor, then click Deploy (top right).

Add your password & API keys

Still on the Worker: click SettingsVariables and Secrets. For each item below click + Add, set Type = Secret, then the name and value, and Deploy when done.

Add HEUS_PASSWORD first — it's a login password you invent. Then add a key for each AI you want. Skip any you don't have; it just shows as "no key" in the hub.

HEUS_PASSWORD
ANTHROPIC_API_KEY
OPENAI_API_KEY
GEMINI_API_KEY
DEEPSEEK_API_KEY
QWEN_API_KEY
ERNIE_API_KEY
COPILOT_API_KEY
Copilot note: Microsoft Copilot has no public API, so this slot uses GitHub Models (free, OpenAI-compatible) via a GitHub token — the closest drop-in.

Copy your Worker URL

Go back to the Worker's main page. Near the top you'll see its address, ending in .workers.dev — something like:

https://heus-hub.your-name.workers.dev

Copy that whole URL — you need it in the last step.

6

Connect the hub

Open HEUS HUB and enter the Worker URL from step 5 and the HEUS_PASSWORD from step 4. Both are saved only in your browser, once per device. Done — start chatting.

If a model errors, it usually just means that provider's key isn't set yet. Add it in step 4 and redeploy.

Want to change the model list or add a provider later? The same code lives at heus-worker/worker.js in your site — edit and redeploy.
