# FormKeep > FormKeep is a form backend for developers and designers. Point any HTML > form's `action` at a FormKeep endpoint, or build one with FormKeep's > visual form builder, and FormKeep collects submissions, filters spam, > sends notifications, and forwards data to tools like Google Sheets, > Slack, and Zapier — all without running a server.
