FormSubmits is a headless form backend that acts as a firewall for your HTML forms. Instead of simply forwarding submissions like most form services, FormSubmits validates every field against configurable server-side rules, stopping bots, spam, and malformed data before it reaches your CRM, database, or integrations.
The service supports over 25 validated field types including email, phone, credit card with Luhn validation, currency, coordinates, and birthdate with age restrictions. You can also define custom regex patterns for specialized validation needs. Spam protection works across multiple layers with honeypot fields, Google reCAPTCHA v2/v3/Enterprise support, AI-powered content analysis, gibberish detection, and IP filtering. File uploads are secured with virus scanning, extension whitelisting, and size limits.
FormSubmits connects to over 30 services out of the box including webhooks, Slack, Discord, Telegram, Google Sheets, Notion, Airtable, HubSpot, and major cloud storage providers. Users can bring their own storage on AWS S3, Azure, or Google Cloud for full data sovereignty.
Additional features include form scheduling with start and end dates, submission limits, geofencing by country, custom success and error pages, and full JSON responses for AJAX submissions.
The service works with any frontend framework or static site generator including React, Vue, Next.js, Astro, and Hugo. Point your HTML form to the FormSubmits endpoint, configure your validation rules in the dashboard, and receive only clean structured data.

Most form backends either skip validation entirely or rely on client-side validation, which is easily bypassed using tools like Postman or automated scripts. FormSubmits enforces validation on the server, so even if someone submits directly to your endpoint, bad data gets rejected before it reaches your systems.
FormSubmits offers 25+ validated field types with strict server-side validation that competitors lack. You get multi-layer spam protection, secure file uploads with virus scanning, 30+ native integrations, and enterprise features like geofencing and bring-your-own-storageโall without writing backend code.
Developers and teams building websites with modern frameworks like React, Next.js, Vue, or static site generators who need reliable form handling without maintaining server infrastructure. Particularly useful for agencies, SaaS products, and businesses where data quality matters.
Over time we built multiple projects, and each one needed form handlingโfrom simple contact forms to complex applications. Initially every project had its own backend processor. Later we tried existing form services, but none offered the server-side validation we needed. FormSubmits was born to solve that problem for ourselves and others facing the same gap.
FormSubmits is a solid choice for anyone needing a simple, no-backend way to handle form submissions, offering ease of setup and reliable delivery of form data to your inbox or endpoints without requiring server-side code.
