What It Is

FormKeep is an online form backend service for designers and developers. Its core idea is straightforward: change the ACTION URL of an existing HTML form to FormKeep, and you can receive and store submissions without running your own server. For static or lightweight sites built with GitHub Pages, Jekyll, Hugo, Gatsby, Next.js, React, WordPress, Squarespace, and similar platforms, it fills a common gap: the backend needed to handle form submissions.

Core Features

In terms of functionality, FormKeep covers the main workflow of a form backend: submission storage, email notifications, Slack notifications, auto-replies, thank-you pages or redirects, spam filtering, server-side data validation, file/image attachments, mobile-friendly forms, hosted landing pages, and form embeds. It supports reusing plain HTML forms directly, while also offering a visual form builder, making it suitable for collaboration between developers and non-engineering roles. For integrations, it natively supports Email, Google Sheets, and Slack, and can connect to 2000+ apps via Zapier. Webhooks also make it easy to push data into internal systems or CRM workflows.

Pricing and Value

FormKeep uses a free-plus-subscription pricing model. The free plan includes 50 submissions/month, spam protection, a form designer, daily notifications, 1-month retention, and unlimited forms, making it suitable for low-volume contact forms. Essential costs $4.99/month, increases the limit to 1k submissions, and adds no branding, Webhooks, and attachments. Professional costs $19.50/month and supports 10k submissions, real-time notifications, all integrations, and auto-replies. Premium costs $59/month and supports 100k submissions, team members, phone support, and permanent retention. Overall, it is friendly to small and mid-sized websites, though multiple forms and high submission volume can push users toward higher tiers.

Pros and Cons

The main advantages are simple integration, no reliance on iframes, JavaScript libraries, or self-hosted servers, clear support for the static-site ecosystem, and a fairly complete set of notifications, anti-spam features, Webhooks, and Google Sheets/Slack/Zapier integrations. The limitations are that the source text does not specify whether it is open source, self-hostable, whether it offers an official API/SDK, or what payment methods are supported. The free plan also has limited submission volume and data retention, while features such as real-time notifications, all integrations, and permanent retention require a paid plan.

Who It’s For and Access from China

FormKeep is suitable for web designers, frontend developers, marketing teams, help desks, and teams that want to quickly launch contact forms, lead capture forms, subscription forms, or booking forms. Access from mainland China is not specified in the source text. Ecosystem services such as Google Sheets, Slack, and Zapier may be affected by local network conditions, so before deployment it is worth testing site access, notification delivery, and the payment flow. Comparable options include Formspree, Getform, Basin, Netlify Forms, Tally, Typeform, and Google Forms.
