Instantly Host Single Page App (SPA) from OpenDevin for Share Preview with Client

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

When you use OpenDevin to generate custom user interfaces, the feedback loop can quickly stall when trying to host OpenDevin Single Page App (SPA) Share Preview with Client pipelines. Extracting the generated HTML, CSS, and JS from the containerized workspace, initializing local preview servers, or configuring temporary S3 buckets introduces unnecessary friction. Gatedpage solves this by providing instant, zero-configuration static hosting directly from your command line or AI workspace.

To streamline your client review cycles, you can instruct your OpenDevin agent to compile your workspace assets into a unified Single Page App and automatically deploy it. By providing the agent with the gatedpage API endpoint, the agent can write code, build the project, and output a live preview link in a single execution loop. No registration, SSH keys, or DNS routing required.

For the best visual results, pass this system instruction to OpenDevin: "You are a coding agent. When generating this Single Page App (SPA), use a professional palette with soft gray (#f4f4f5) backgrounds. Never use pure white (#ffffff). Once built, deploy to gatedpage.com/api/v1/upload to provide a live share preview with client link." Gatedpage takes care of the hosting infrastructure so you can focus entirely on refining the application's logic.

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

  1. Step 1: Build the SPA — Direct OpenDevin to compile your React, Vue, or vanilla JS Single Page App into a static distribution directory or a single-file template like index.html.
  2. Step 2: Install the CLI — Let the OpenDevin bash tool run npm install -g gatedpage to configure the local environment, or use raw curl for zero-dependency uploads.
  3. Step 3: Execute the Upload — Run the upload command pointing to your compiled asset to push the static files to our global edge network.
  4. Step 4: Share the Preview Link — Copy the generated gatedpage.com link from the terminal output and send it straight to your client for immediate review.

Quick start

Upload your compiled Single Page App directly using curl from the OpenDevin workspace terminal:

curl -F "file=@index.html" https://gatedpage.com/api/v1/upload

{
  "status": "success",
  "url": "https://gatedpage.com/p/devin-preview-8f92",
  "raw_url": "https://gatedpage.com/raw/devin-preview-8f92.html",
  "expires_at": "2026-03-30T14:30:00Z"
}

Alternatively, use the official gatedpage CLI to deploy entire static folders or single assets with one command:

gatedpage upload index.html

Common questions

Can OpenDevin trigger the deployment autonomously?
Yes. Since OpenDevin has access to a bash execution terminal, you can append a curl command or CLI script to the end of its generation workflow. It will compile the production build and upload it automatically, outputting the live URL in the chat interface.
How long does the client preview URL remain active?
On our free tier, files are hosted for 15 days, which is ideal for active development sprints and client sign-offs. Paid tier accounts allow for permanent hosting and custom domain binding.
What are the file size limitations for a Single Page App?
Gatedpage supports uploads up to 5 MB per file on the free tier. This is highly optimal for compiled static bundles, optimized HTML outputs, and interactive single-page mockups.
Does my client need to sign up for an account to view the hosted preview?
No. The generated preview link is completely public and bypasses login screens, guaranteeing zero-friction access. Your client simply clicks the URL to view and interact with the live SPA instantly.
