VaultMail

Every existing temp-mail service is either a half-finished open source project, an ugly ad farm built in 2012, or a closed SaaS with no API. We're building the platform that serves all three real audiences: humans who need a throwaway inbox, developers who need programmatic access (Mailinator's territory), and AI agents who need real email addresses they can own and act on.

The moat is the domain portfolio: dropcatched .bg domains with real mail history. They aren't on the universal blocklists Gmail and Outlook use against the well-known temp-mail brands — so they work on sites that block traditional disposable mail.

The stack is intentionally boring where boring works: Postfix to receive, Python (FastAPI + aiosmtpd) to process, Postgres to store, Redis pub/sub to push to the browser via SSE, Next.js to render. Self-hosted on a small AMD VPS in Falkenstein.

Self-hosted, privacy-first, and built to last.
