Hi everyone, I'm Elijah and I built Orisift. It started with support tickets about failed signups that ended with someone shrugging at DNS tools. I wanted a check that says what it actually proved and what it couldn't, instead of a green tick. A few things it does that I care about: a phone number in a range regulators keep for TV drama (020 7946 0958 in the UK, 555-0100 to 0199 in the US) is flagged with the source; a DNS timeout comes back as insufficient evidence, not a rejection, and a lookup that establishes no evidence costs nothing; and every reason says whether the person signing up or your code should fix it. If you use Supabase Auth, there's a before-user-created hook in the Node SDK that screens a signup before the user is created and makes you choose what happens if screening is down. You can try it on the homepage with 3 checks a day and no account. I'd really like to hear where it gets things wrong.
