osforms is a form backend SaaS that stores submissions and routes them to your own integrations — Resend, Google Sheets, and webhooks. Free because you bring your own API keys.

Why osforms

Every competitor (Formspree, FormBold, Basin) paywalls integrations behind $5–15/month even though your own API keys power them. osforms flips that — 100 free submissions/month with all integrations included.

Quick Start

Get your first form running in 2 minutes

Resend Integration

Forward submissions to email via Resend

Google Sheets

Append submissions to a spreadsheet automatically

React SDK

Embed conversational or classic forms in your app

How it works

  1. Create a form in your dashboard — get a unique endpoint URL
  2. Point your HTML form at the endpoint
  3. Configure integrations with your own API keys
  4. Submissions are stored and routed instantly
<form action="https://osforms.com/api/v1/f/your-form-slug" method="POST">
  <input type="text" name="name" placeholder="Your name" />
  <input type="email" name="email" placeholder="Your email" />
  <textarea name="message" placeholder="Your message"></textarea>
  <button type="submit">Send</button>
</form>
No JavaScript required. Works with any HTML form.
