Publish HTML Content with GitHub Gist and HTML Preview

📌 Who’s it for

This subworkflow is designed for developers, AI engineers, or automation builders who generate dynamic HTML content in their workflows (e.g. reports, dashboards, emails) and want a simple way to host and share it via a clean URL, without spinning up infrastructure or uploading to a CMS.

It’s especially useful when combined with AI agents that generate HTML content as part of a larger automated pipeline.

⚙️ What it does

This subworkflow:

Accepts raw HTML content as input. Creates a new GitHub Gist with that content. Returns the shareable Gist URL, which can then be sent via Slack, Telegram, email, etc.

The result is a lightweight, fast, and free way to publish AI-generated HTML (such as reports, articles, or formatted data outputs) to the web.

🛠️ How to set it up

Add this subworkflow to any parent workflow where HTML is generated. Pass in a string of valid HTML via the html input parameter. Configure the GitHub credentials in the HTTP node using an access token with gist scope.

✅ Requirements

GitHub account and personal access token with gist permissions

🔧 How to customize

Change the filename (report.html) if your use case needs a different format or extension. Add metadata to the Gist (e.g., description, tags).
