As answered by people managing Formboost.app and PDFShift.
Formboost.app's answer
Formboost is a developer-first, serverless form backend that lets developers collect and manage form submissions without building or maintaining a backend. It combines a simple HTML/API integration with secure submission storage, email notifications, real-time webhooks, a submission dashboard, and AI-powered spam protection.
Formboost.app's answer
Formboost provides a simple, developer-focused way to add a form backend without server configuration or an SDK. Developers can use a standard HTML form, REST API, or webhooks while getting submission management, notifications, spam protection, and integrations in one platform. It also offers a free plan with no credit card required.
Formboost.app's answer
Formboost is primarily built for developers, freelancers, indie hackers, startups, and teams that need a reliable form backend without building their own server-side form processing system. It works with static websites and frontend frameworks such as HTML, React, Next.js, SvelteKit, and Astro.
Formboost.app's answer
Formboost was created to solve a common developer problem: simple forms shouldn't require building an entire backend. The idea is to provide one secure API endpoint that handles form submissions, storage, notifications, webhooks, and spam protection, allowing developers to focus on their product instead of maintaining form infrastructure.
Formboost.app's answer
Formboost is built as a modern web-based SaaS platform with a REST API and webhook infrastructure. It is designed to work with HTML and modern frontend frameworks including React, Next.js, SvelteKit, and Astro, with TypeScript-friendly API response types. Note: I would not list specific backend technologies such as Node.js, PostgreSQL, AWS, etc. unless you want to publicly disclose Formboost's actual internal stack.
Formboost.app's answer
Formboost is currently in public beta and is focused on developers, freelancers, indie hackers, startups, and growing teams. We are building our customer base and do not currently publicly disclose a list of major customers.
