A local-first Hunter.io alternative for Mac
Hunter.io finds and verifies emails from the cloud. Octopi does it across a whole spreadsheet on your Mac — trying several email-finder providers you connect, verifying each address, with a source on every row.

Questions
Does Octopi have its own email database?
No. It calls the email-finder providers you connect with your own keys, and can waterfall across several for better coverage.
Can it verify emails?
Yes, with a verifier key (ZeroBounce, NeverBounce or MillionVerifier). Each address gets a status: valid, invalid, catch-all or unknown.
Is my list uploaded?
No. Your list stays on your Mac; each lookup goes directly from your Mac to the providers you choose.
Can I use my existing Hunter or other keys?
Yes. You bring your own provider API keys; they’re stored locally on your Mac.
