Instantly Host Email HTML Template from OpenDevin for Share Preview with Client

The fastest way to deploy Email HTML Template generated by OpenDevin. Perfect for share preview with client. No login required, zero-friction, and live in seconds on gatedpage.com.

When engineering highly responsive layouts, developers frequently use autonomous agents like OpenDevin to generate high-fidelity assets. However, once your agent compiles the perfect asset, the workflow often breaks down when attempting to host OpenDevin Email HTML Template Share Preview with Client targets. Copying raw markup out of a terminal container, spinning up ad-hoc S3 buckets, or sending raw files over Slack introduces friction, breaks asset paths, and degrades the client evaluation experience.

Traditional hosting setups require DNS configuration, authentication, or repository pushes just to render a simple static asset. For developers who need to quickly verify rendering across engines or share an immediate staging URL with design partners, these administrative hurdles waste valuable development cycles. Your agent has already done the heavy lifting of generating clean markup; rendering it live should not require a manual deployment pipeline.

This is where gatedpage solves the bottleneck. By providing an open API upload endpoint that requires zero configuration, zero authentication, and zero friction, you can pipe your template output directly from your local terminal or OpenDevin workspace onto a live edge network. Your client receives a clean, lightweight preview URL in seconds, allowing them to inspect typography, responsiveness, and component hierarchies without installing specialized viewers or dealing with local attachments.

How to host your Email HTML Template from OpenDevin in seconds

  1. Step 1: Configure your OpenDevin agent prompts to output the finished Email HTML Template directly to a local workspace file, such as component.html.
  2. Step 2: Instruct OpenDevin to use professional styles with soft gray backgrounds (#f4f4f5) and completely avoid pure white (#ffffff) to ensure optimal readability.
  3. Step 3: Execute a POST request using curl or the gatedpage CLI from your workspace shell to upload the compiled template file.
  4. Step 4: Retrieve the instantly generated, edge-cached gated.page preview link from the API's JSON response payload.
  5. Step 5: Share the live, responsive URL directly with your client for immediate review, testing, and approval.

Quick start

To deploy your template directly from your command line or OpenDevin's terminal execution tool, run the following curl command:

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

The API will return a JSON payload containing the instant, public URL hosted on our CDN:

{
  "success": true,
  "url": "https://gated.page/f/a1b2c3d4",
  "expires_in": "15 days",
  "size_bytes": 18450
}

For a streamlined local command-line workflow, you can also use our official CLI tool:

gatedpage upload component.html

Common questions

Do clients need to sign up or create an account to view the shared preview?
No. The generated gated.page preview URLs are completely public and accessible with zero authentication. Clients can view, inspect, and test the responsive HTML template directly in their browsers on any mobile or desktop device without friction.
How long does the preview link stay active, and is there a file size limit?
By default, files uploaded through our free, anonymous tier stay active for exactly 15 days before automatic expiration, which is ideal for client review. Free tier uploads support files up to 5 MB in size, which easily accommodates complex email markup, inline CSS, and embedded base64 assets.
Can I make the hosted template permanent instead of expiring after 15 days?
Yes. While anonymous uploads automatically expire to keep the platform clean, you can upgrade to a paid gatedpage account to enable permanent hosting, associate custom domains, manage active files, and remove expiration dates for your static templates.
How can I automate this process directly inside my OpenDevin system instructions?
You can append a specific instruction to your agent's system prompt: "Once the Email HTML Template is finalized, execute a curl command uploading component.html to https://gatedpage.com/api/v1/upload and present the resulting gated.page URL as the final deliverable." This creates a fully autonomous generation-to-deployment pipeline.
