# What is SiteBackend?

> SiteBackend gives static sites a form backend and customer testimonials. It handles submissions and testimonials for you, with no server to run.

SiteBackend is the backend a static website doesn't have. It does two jobs:

- **Forms.** Point an HTML form at a SiteBackend endpoint, and it receives the submission, filters spam, stores it, adds the sender to your contacts and notifies you.
- **Testimonials.** Embed a form where customers leave a testimonial, approve the good ones, and show them on your site as a wall, carousel, highlight or rating badge.

Your site stays static: there's no server, database or plugin to run.

## Who is it for?

- **Static and Jamstack sites** built with HTML, Astro, Next.js, Nuxt, Hugo, Eleventy, Jekyll or site builders like Webflow.
- **Freelancers and agencies** who manage forms and testimonials for many clients: each client gets their own workspace.
- **Anyone who doesn't want to maintain a server** just to handle a contact form or show a few testimonials.

## Plans

**Free** includes one site, 100 submissions a month (extras are kept until you upgrade) and 10 testimonials on show per site. **Pro** is $9/month or $90/year, with unlimited sites, submissions and testimonials, and no SiteBackend branding on widgets. See [plans and limits](https://sitebackend.com/docs/workspace/plans-and-limits).

## How is it organized?

A **workspace** holds your plan and teammates. It contains **sites**, one per website, and each site has its **forms**, **contacts** and **testimonials**. See sites and how it works.
