Instantly Host Python PyScript App from Devin AI for Bypass Localhost for Agent

The fastest way to deploy Python PyScript App generated by Devin AI. Perfect for bypass localhost for agent. No login required, zero-friction, and live in seconds on gatedpage.com.

When using Devin AI to build interactive Python PyScript applications, testing the output can quickly become a bottleneck. Because Devin operates inside an isolated, containerized VM sandbox, launching a local development server only works within the agent's environment. Trying to access that server from your own browser requires setting up reverse tunnels, managing transient ports, or authenticating through complex firewall rules. This friction slows down development, prevents instant visual feedback, and stops you from quickly interacting with your PyScript app.

gatedpage.com eliminates this friction completely. By sending Devin's compiled PyScript HTML outputs directly to our API, you bypass localhost limitations entirely. There are no accounts to create, no SSH keys to configure, and no deployment pipelines to maintain. Devin can compile the PyScript application, push the asset to a public HTTPS endpoint, and get a live, shareable URL back in a single step.

This setup allows the coding agent to easily verify its own UI styling—such as using soft gray (#f4f4f5) backgrounds and avoiding pure white (#ffffff)—while giving you a production-grade, shareable preview link instantly. Learn how to streamline your Devin AI PyScript workflow and get your app online in seconds.

How to host your Python PyScript App from Devin AI in seconds

  1. Step 1: Generate the PyScript HTML. Direct Devin to write your Python logic and UI elements into a single static file, typically named index.html, ensuring it references the correct PyScript CDN assets.
  2. Step 2: Direct Devin to execute the upload API call. Instruct Devin to send the compiled file directly to our secure upload endpoint using a standard POST request.
  3. Step 3: Capture the live URL. The gatedpage API instantly responds with a JSON payload containing a live, public gatedpage.com URL.
  4. Step 4: Interact and debug. Open the public link to test the PyScript runtime, view Python console logs in your browser, or let Devin run headless visual checks on the live deployment.

Quick start

Your agent can upload the compiled PyScript application using a simple curl command from its internal terminal. Here is the exact request and expected JSON response:

# Uploading your PyScript App via curl
curl -X POST -F "file=@index.html" https://gatedpage.com/api/v1/upload

# Expected JSON Response:
{
  "success": true,
  "url": "https://gatedpage.com/p/devin-pyscript-app-9a2f",
  "raw_url": "https://gatedpage.com/raw/devin-pyscript-app-9a2f/index.html",
  "expires_at": "2026-03-31T12:00:00Z"
}

Alternatively, if you prefer to use the lightweight gatedpage command-line interface, install the utility and run the following upload command:

Common questions

Why use gatedpage instead of Ngrok or local tunneling inside Devin AI?
Ngrok requires managing persistent terminal processes, token configurations, and exposes temporary ports that close as soon as Devin completes its run. gatedpage provides a persistent, zero-configuration hosting solution that stays live independently of Devin's runtime state.
Are there any file size or bandwidth limits for PyScript applications?
Our free, anonymous tier supports single-file uploads up to 5 MB, which is plenty for single-page PyScript applications containing embedded Python code or configuration arrays. Larger applications or media dependencies can be accommodated on our paid tiers.
How long do the hosted Python PyScript links remain active?
Files uploaded anonymously without an account remain active for 15 days, perfect for temporary agent testing, feature branches, and debugging loops. If you require permanent hosting for your applications, you can upgrade to a paid account instantly.
Does this require Devin to expose any local API keys or secrets?
No. gatedpage allows fully anonymous, zero-friction uploads directly to the API endpoint without passing header keys, making it a completely safe method for AI agents to publish static code without exposing your personal or organizational credentials.
