For Developers

Form Backend for Developers Who Ship Fast

API-first form backend for developers. JSON responses, webhook integrations, spam protection, and zero backend code. Works with React, Vue, Next.js, and any framework.

The Problem

Building form backends is tedious

Every project needs form handling — validation, storage, email sending — but building this from scratch every time wastes hours you could spend on actual product features.

Managing email infrastructure is painful

Setting up SMTP, handling deliverability, managing bounces, and configuring SPF/DKIM records just to send a notification email from a contact form is overkill.

Spam floods submissions without protection

Without proper spam filtering, bots will hammer your form endpoints within hours of going live. Building and maintaining spam detection is a project in itself.

Static sites lack server-side capabilities

JAMstack and static sites deployed on Vercel, Netlify, or GitHub Pages have no server to process form submissions, forcing you to spin up separate API services.

How FormsList Helps

Drop-in API endpoint

Point your form's action URL to a FormsList endpoint. Accepts both URL-encoded and JSON payloads. Get structured JSON responses for AJAX submissions.

Works with every framework

React, Vue, Svelte, Next.js, Astro, plain HTML — if it can make an HTTP POST, it works with FormsList. No SDK required, though we provide code snippets for popular frameworks.

Webhooks for custom workflows

Forward submissions to your own API via webhooks with automatic retries. Build custom processing pipelines without managing form infrastructure.

Built-in spam protection

Honeypot fields, reCAPTCHA support, and AI-powered spam filtering keep your inbox clean without any configuration on your end.

Recommended Integrations

Webhooks

FormsList's webhook integration lets you forward form submissions to any HTTP endpoint in real time. Every time a form is submitted, FormsList sends a POST request with the submission data as a JSON payload to your webhook URL. This is the most flexible integration, enabling you to connect FormsList to any service, API, or custom backend. Webhooks are perfect for developers who want to process form data in their own systems — storing it in a custom database, triggering workflows, sending to a CRM, or connecting to services that FormsList doesn't have a native integration for. You can configure multiple webhook URLs per form, add custom headers for authentication, and set up retry logic for failed deliveries. FormsList logs all webhook attempts with status codes and response bodies for easy debugging.

Slack

Never miss a form submission again. FormsList's Slack integration delivers every submission directly to your chosen Slack channel in real time. Whether it's a new lead, a support request, or a piece of feedback, your team sees it the moment it arrives — without leaving Slack. The integration formats each submission into a clean, readable Slack message with all form fields displayed as structured data. You can configure which channel receives notifications, customize the message format, and even filter which submissions trigger a Slack notification based on field values. Setting up the Slack integration takes under two minutes. Connect your Slack workspace from the FormsList dashboard, choose a channel, and you're live. No webhooks to configure manually, no code to write, and no Zapier subscription required.

Discord

FormsList's Discord integration sends form submissions directly to your Discord server via webhook. Every time someone fills out your form, a formatted message appears in your chosen Discord channel with all the submission details. This integration is perfect for communities, indie hackers, small teams, and gaming projects that use Discord as their primary communication hub. Instead of checking a dashboard for new submissions, your team gets notified where they already are. The setup uses Discord's native webhook system, which means it's fast, reliable, and doesn't require any bots or third-party services. Create a webhook in your Discord channel settings, paste the URL into FormsList, and submissions start flowing in immediately.
