I built this side project over the weekend to help block unwanted signups and clean up email lists. Most disposable email checker APIs out there are either too expensive or rely on outdated lists from unmaintained open-source packages. So I decided to create my own. It's completely free to use and will stay that way. I'm running it on Cloudflare Workers + KV which is incredibly cheap to host and costs me almost nothing.

Use cases with api:

- clean up your email lists

- add protection to your AI SaaS from unwanted temp domains.
