Private guest inbox
Mailfab guest inboxes are tied to the browser session that created them instead of being presented as a public inbox listing.
Mailinator alternative
A private Mailinator alternative for temporary inbox workflows.
mailfab is built for teams and individuals who want temporary inboxes without making the guest experience feel like a public mailbox directory. Start with a browser-private guest inbox, then move to API, CLI, webhook, and self-hostable workflows when needed.
Developer automation
Signed-in users can use API keys, CLI JSON output, webhooks, and share links for repeatable workflows.
Self-hostable stack
The public repository documents a Next.js and Cloudflare Workers deployment model with D1 and KV.
Use case fit
Choose mailfab when privacy of the quick inbox matters.
The guest inbox is designed for quick receive-only verification while keeping access scoped to the browser session. That makes it a practical fit for one-off signups, QA checks, and short-lived flows.
- Open a guest inbox without registering first.
- Copy the generated address and wait for incoming mail.
- Replace the inbox with a new random address when the task changes.
Developer fit
Move from manual checks into API and CLI automation.
When temporary email becomes part of product testing, Mailfab's signed-in workflows add API keys, CLI commands, webhooks, sharing, and optional sending where the account is allowed to send.
- Use the CLI to create, wait, read, and delete inboxes in scripts.
- Use webhooks for new inbound mail notifications.
- Keep Playwright, CI, and agent workflows responsible for parsing product-specific codes or links.
