Want to add a contact form to your Jamstack or static site? Form backend services can help you do that.
This repository is a comparison of free form backend services for static sites. It includes a list of services, their features, and limitations. The list is divided into two sections: open-source and self-hostable services, and free plans from popular form backend providers.
This list is not exhaustive, and there may be other services available that are not listed here. If you find any inaccuracies or have suggestions, feel free to open an issue or submit a pull request. We aim to make this list as accurate as possible, but keep in mind that features and pricing may change over time. Refer to the providers' websites for the most up-to-date information.
Open source form backends that you can host yourself. These services usually have an instance available for public use as well. If there are usage limits that apply to this instance, they will be in the table below.
