Hey Product Hunt
I'm the maker. I built Mailfly after getting tired of temp-mail sites that
are slow, ad-stuffed, and ugly.
Mailfly gives you a disposable inbox instantly:
- No signup, no cookies, no traces
- Code/link shows up in seconds (live inbox, no refresh button mashing)
- Multiple domains, QR for mobile, auto-detected OTP codes
- The address self-destructs on a timer
For developers there's a clean API + JS/Python SDKs — perfect for e2e tests,
CI pipelines, and anywhere you need a throwaway inbox programmatically.
It's built entirely in TypeScript, runs on a single VPS, and the free tier
genuinely stays free. Premium just buys you longer-living inboxes, custom
addresses, and forwarding.
Would love your feedback — especially on what would make you choose it over
the temp-mail site you currently use. I'm in the comments all day.

how long does the inbox actually stick around before it burns out, and can i pick a longer window if i need to wait on a slow verification email?

The instant burn with no signup feels really well thought out, especially for CI use cases where test flakiness from shared inboxes is a nightmare. Love that it just works without a dashboard getting in the way.

finally something that actually delivers the magic link in under 10 seconds. love that i didn't have to make an account just to grab a verification code.
