SubmitraX is a form backend service for developers building static and serverless sites. Instead of writing Lambda functions or configuring email APIs, you point your HTML form's action attribute at a SubmitraX endpoint and submissions are delivered to your email, Slack, Discord, or webhooks automatically. Includes AI-generated form templates, CSV exports, and an n8n community node.
SubmitraX API PlatformSubmitraX's answer
SubmitraX is the only form backend that combines a zero-config REST endpoint with AI-generated form templates and a native n8n community node โ all in one tool.
Most form backends stop at "we receive your submission and email it to you." SubmitraX goes further:
n8n-nodes-submitrax): pipe submissions directly into any workflow โ HubSpot, Notion, Slack, Google Sheets, 400+ integrationsSubmitraX's answer
Three reasons:
1. It works with any host. Unlike Netlify Forms (locked to Netlify) or Vercel's form solutions (locked to Vercel), SubmitraX works wherever your site lives โ GitHub Pages, Cloudflare Pages, a bare VPS, or any static host.
2. The setup is genuinely 3 steps. Set your form's action attribute to your endpoint URL, make sure inputs have name attributes, add a submit button. No SDK, no API keys, no configuration files. Competitors often require JavaScript SDKs or account-level API tokens.
3. It's built for automation. The n8n node make SubmitraX the only form backend designed to plug into modern workflow tools out of the box โ not as an afterthought.
SubmitraX's answer
Developers building static sites, JAMstack apps, and serverless architectures who need form handling without backend infrastructure.
More specifically:
SubmitraX's answer
SubmitraX was built by a developer who kept solving the same problem on different projects.
Every static site eventually needs a contact form. And every time, the answer was the same: write a serverless function, configure an email service, handle CORS, deploy it, maintain it. For something that should take five minutes.
After doing this for the third time across different client projects, it became clear the pattern deserved its own tool. SubmitraX started as an internal utility and became a product when other developers kept asking to use it.
The goal has always been the same: get out of your way. You build the site. SubmitraX handles the forms.

Another difference is that in .NET Core, we can integrate with OpenAPI out of the box (it is part of the framework), while in Symfony, an API-based application with OpenAPI features is only available using a third-party toolโthe API Platform. - Source: dev.to / about 2 years ago
API Platform is a great tool for rapid API development, but it has a lot of not-so-well-documented features which can sometimes lead to confusion. Playing around with a new project of mine I've stumbled into one: tests were failing for my validation assertions of endpoints' responses! - Source: dev.to / about 2 years ago
Technically API Platform is not part of Symfony. Although, they are both French. ๐. - Source: dev.to / over 2 years ago
Probably API-platform. The website is down at the moment, but: https://github.com/api-platform/api-platform It's Symfony based (and plays nice in that ecosystem), also allows you to describe entities via Schema org vocab, has a client generator, and comes with docker-compose and helm charts. I've used it extensively to build various headless services. It's really easy to expose annotated Doctrine entities. Source: about 3 years ago
API Platform is a framework for API-first projects, built on top of Symfony components. Let's see how to create a minimal and lightweight starter project in just 5 minutes! - Source: dev.to / about 3 years ago
