Formboost
Serverless form backend with AI spam protection
About Formboost
Formboost is a developer-first form backend API. Connect any HTML form to receive submissions, email alerts, webhooks, and AI-powered spam filtering without a server.
Build your form, Formboost handles the backend
Formboost operates as a hosted form submission API which enables static sites and frontend frameworks including React and Next.js and Vue and Astro and SvelteKit and basic HTML to submit their forms. You can obtain secure storage and email alerts and webhook transmission and AI-based spam protection when you set your form's action attribute to a designated Formboost URL. The system functions without any requirement for backend programming or API endpoints or database access.
Key features
AI-powered spam protection: The system applies heuristics to every submission while an AI model evaluates uncertain cases by analyzing the entire form to produce a spam score which ranges between 0 and 100. No CAPTCHA needed.
One form endpoint for any stack: Point a plain HTML action at your endpoint or POST JSON from JavaScript frameworks. CORS is handled automatically.
Email notifications: Every submission is delivered to your inbox in seconds with all fields included. Configure recipient addresses and subject lines per form.
Submission dashboard and CSV export: Search and filter submissions by field, date, or spam score. Mark items as reviewed and export your full history to CSV.
Webhooks and REST API: POST submissions to any HTTPS endpoint with custom headers, test payloads, and a delivery record for each attempt.
Native integrations: Connect Slack, Discord, Telegram, Google Sheets, Zapier, and n8n without writing glue code.
Custom redirects: Send users to a thank you page or external URL after submission.
Who it is for
Formboost enables developers to create landing pages and contact forms and feedback surveys and internal tools and multi-step workflows. The platform serves as a perfect tool for indie hackers and freelancers and expanding teams because it enables them to gather submissions without needing to operate their own servers.
Why Formboost stands out
Formboost operates as a developer-oriented solution which competes with Formspree and similar services. Users can access a straightforward API through this platform which eliminates the need for software development kits and enables them to complete the setup process within sixty seconds. The platform operates through multiple worldwide data centers which maintain a 99.99% uptime SLA and deliver 15ms average response time and protect all data through encryption and provide continuous monitoring throughout every hour of the day. The upcoming software updates will include file upload functionality and form tracking features and automated response generation.
