🚀 Built a CLI for disposable email APIs (made for dev workflows)
Hey everyone 👋 I noticed most temp email tools are slow, UI-heavy, and painful to use inside real dev workflows — especially for testing OTPs, automations, or scripts. So I built a CLI for FreeCustom.Email that lets you: • Generate inboxes instantly • Fetch emails via terminal • Use directly in scripts / CI / AI agents • Skip dashboards completely Basically — no more clicking around just to test an OTP flow. You can plug it into: test scripts automation workflows AI agents backend dev environments Docs + CLI: https://www.freecustom.email/api/cli Would love feedback from devs who actually build stuff 🙏

It is faster than other free email alternatives. I would love to see a rotating selection of domains when changing addresses, even on the free plan.
@alcazarsec we have many rotating domains on free plans too.. and recently, one of our user donated two domains for all guest users.. im very gratefull for such users..:)
