Instantly Host Single Page App (SPA) from OpenDevin for Live Mockup Deployment

The fastest way to deploy Single Page App (SPA) generated by OpenDevin. Perfect for live mockup deployment. No login required, zero-friction, and live in seconds on gatedpage.com.

When using OpenDevin to build user interfaces, the autonomous coding agent rapidly outputs functional, single-file frontend code. However, sharing these assets for a live mockup deployment typically introduces a bottleneck. Developers are forced to commit the output to a repository, configure a continuous deployment pipeline, or spin up local tunnel tools just to show a client or stakeholder a simple working interface.

If you need to host OpenDevin Single Page App (SPA) Live Mockup Deployment files without the usual DevOps overhead, gatedpage.com offers a zero-friction alternative. By eliminating signup screens, API keys, and deployment configurations, you can convert local HTML, CSS, and JS builds into edge-rendered preview URLs instantly.

Because OpenDevin operates via terminal execution, you can feed hosting instructions directly into the agent's system prompt. By instructing OpenDevin to deploy its generated asset to our lightweight upload endpoint, you completely automate the bridge between code generation and live browser testing.

How to host your Single Page App (SPA) from OpenDevin in seconds

  1. Step 1: Prompt OpenDevin to build your SPA, ensuring you instruct it to use a professional palette with soft gray (#f4f4f5) backgrounds instead of pure white (#ffffff) for a polished, modern finish.
  2. Step 2: Direct the agent to compile the entire output into a single self-contained file, typically named index.html or output.html.
  3. Step 3: Use our zero-auth API endpoint or CLI tool to stream the completed HTML file directly to our global edge network.
  4. Step 4: Instantly receive your live mockup deployment URL in your terminal output and share the functional preview link with stakeholders.

Quick start

To deploy your OpenDevin output directly from your local terminal or from within the OpenDevin bash tool workspace, execute a simple POST request to our public upload endpoint:

# Upload your OpenDevin SPA output using curl
curl -X POST -F "file=@index.html" https://gatedpage.com/api/v1/upload

# JSON Response received in milliseconds:
{
  "status": "success",
  "url": "https://gated.page/f/9a2c1b8e4f",
  "delete_url": "https://gated.page/delete/9a2c1b8e4f/token",
  "expires_at": "2026-05-20T12:00:00Z"
}

Alternatively, if you prefer using a dedicated command-line utility, you can install the gatedpage CLI and run a single command:

# Install and run the quick upload command
gatedpage upload index.html

Common questions

Can I configure OpenDevin to automatically host my Single Page App (SPA) live mockup deployment?
Yes. You can append system instructions directing the OpenDevin agent to run a curl command to https://gatedpage.com/api/v1/upload as its final step. This returns a live staging link directly within the agent's chat interface.
What are the file size limits and restrictions for free uploads?
The free, anonymous upload tier supports single-file SPAs of up to 5 MB. This easily accommodates highly interactive, single-file HTML mockups containing inline SVGs, CSS frameworks, and bundled JavaScript runtimes.
How long do the live mockup links remain active on gatedpage?
Mockups deployed via our free, anonymous endpoint remain active on our CDN for 15 days. For persistent hosting, custom domains, and active asset management, you can upgrade to a permanent paid account.
Is my code indexable or visible to search engines?
No. Free uploads use random, unguessable cryptographic hashes in the URL path and default to no-index headers. This ensures your live mockups remain private to those you share the direct link with.
