About IsItDisposable
IsItDisposable detects disposable and throwaway emails at signup. Stop trial abusers cycling burner emails through your free tier, and keep throwaways from wrecking your list quality. A live dataset of 211,812 domains, MX-validated and refreshed daily, with about 320 new ones appearing every day. One API call or a drop-in script tag, and it fails open: if we are ever down, signups keep working. Relays like Apple Hide My Email are flagged, not blocked. Free plan plus a 14-day trial, no card.
About SublimeKeys
Most license key tools are either roll-your-own scripts (fragile, no offline story) or enterprise DRM (overkill for a solo dev). SublimeKeys sits in between: one tiny API to generate, activate, and verify keys — device-locked, revocable, with offline verification lasting 7 days without a network call. Ships with Python and Node/Electron SDKs, a free tier, and a dashboard live in 12 languages. Already the license server behind ReelNox Studio and BackDrop_.
