html.contact

Product Introduction

1. Definition: html.contact is a backend-as-a-service (BaaS) platform specifically designed for form processing. It acts as a serverless endpoint that receives POST requests from standard HTML forms and handles the complex backend logic of email delivery, data management, and security.
2. Core Value Proposition: It exists to eliminate the need for custom backend code, server management, or third-party plugins to make static HTML forms functional. Its primary value is enabling developers and site owners to add fully-featured contact forms, lead capture forms, or application forms to any website using only front-end HTML, with zero server-side dependencies.

Main Features

1. Serverless Form Endpoint: The product provides a unique, public-facing URL (e.g., https://html.contact/f/hc_pub_[key]) that acts as the action attribute for an HTML <form>. This endpoint accepts POST requests with standard application/x-www-form-urlencoded or multipart/form-data encoding. It validates the submission, parses named input fields (name, email, message), and initiates the configured workflow without requiring JavaScript, SDKs, or CORS configuration.
2. Verified Email Routing with Attachments: Upon receiving a valid submission, the system routes the data to pre-verified email inboxes specified in the dashboard. It supports CC/BCC, custom reply-to addresses, and securely processes one file attachment per submission (e.g., PDF, images). The attachment is stored securely and can be accessed via the logs or API, separating potentially large files from the email body itself.
3. Comprehensive Submission Management & API: All form submissions are logged in a private dashboard with details on status (e.g., accepted, blocked). Data can be exported in CSV or JSON formats. A full private API provides programmatic access to both form configuration and submission data, allowing for integration with other tools and automated workflows. Public POST endpoints can also be configured for webhook-like functionality.
4. Proactive Security & Spam Controls: The platform implements server-side security checks before processing data. Key features include domain allowlisting, where only submissions originating from specified domains (like yourdomain.com) are accepted, preventing form hijacking. It also runs internal spam detection algorithms to filter out malicious or low-quality submissions before they reach the inbox or logs.

Problems Solved

1. Pain Point: The technical complexity and maintenance overhead of building a secure, reliable backend to process form submissions, handle file uploads, and send emails for static sites or Jamstack applications.
2. Target Audience: Front-end developers working with static site generators (Astro, Next.js, Gatsby), owners of sites on static hosts (GitHub Pages, Cloudflare Pages, Netlify, Vercel), no-code/low-code builders using platforms like Webflow or Framer, and full-stack developers seeking to offload a common backend task to a specialized service.
3. Use Cases: Adding a functional contact form to a portfolio website hosted on GitHub Pages. Creating a lead generation form with file upload (e.g., resume, proposal) on a marketing site built with Webflow. Implementing a simple order inquiry form for a small business Shopify store without using a heavy app. Providing a secure submission point for forms built by AI coding assistants (like Cursor, v0, Claude) that generate front-end code.

Unique Advantages

1. Differentiation: Unlike many form builders that require embedded JavaScript widgets or lock core features (attachments, multiple recipients, API access) behind paid plans, html.contact uses a transparent, standards-based HTML POST method. Its Free plan offers the complete production backend with all features, limited only by submission volume, allowing for full testing and deployment before upgrade.
2. Key Innovation: The "public browser key" (hc_pub_) system. This approach exposes the minimal necessary endpoint in client-side code while keeping authentication, configuration, and sensitive logic server-side on html.contact's platform. It combines the simplicity of a plain form action with the security and power of a managed backend, bridging the gap between static HTML and dynamic functionality.

Frequently Asked Questions (FAQ)

1. How does html.contact work with static websites? You simply replace the action URL in your standard HTML <form> tag with the unique endpoint provided by html.contact. Your static site sends a POST request directly to this endpoint, which then processes the data, sends emails, and logs the submission—all without any JavaScript or backend code on your hosting server.
2. Is html.contact secure for handling form data and attachments? Yes, it employs multiple security layers. Domain allowlisting ensures only your specified websites can submit to your form endpoint. Submissions undergo server-side spam screening. Attachments are processed and stored securely on html.contact's infrastructure, not emailed as direct attachments, which can bypass email size and security filters.
3. Can I use html.contact with React, Vue, or other JavaScript frameworks? Absolutely. You use the same native HTML <form> element within your framework components. Ensure the form uses method="POST" and the action points to your html.contact endpoint. No framework-specific SDK is needed, as it relies on the browser's native form submission behavior.
4. What happens when I exceed the Free plan's 250 submissions? The form continues to function, but new submissions will be queued and not processed until you upgrade to a paid plan. This ensures your live site does not break, giving you time to upgrade based on actual traffic volume. The backend and all features remain the same.
5. How does html.contact compare to traditional form mailer scripts or services like Formspree? Unlike PHP mailer scripts which require server configuration and are prone to spam and security issues, html.contact is a fully managed service. Compared to other SaaS form endpoints, html.contact distinguishes itself by offering the complete feature set (attachments, API, routing) on its free tier and using a transparent, non-widget HTML POST approach that gives developers full control over form styling and behavior.
