24 alternatives to AuthFill
I built AuthFill after catching myself switching between tabs for the hundredth time just to copy a 6-digit verification code. You know the dance: sign up → wait for email → hunt through promotions tab → memorize code → switch back → already expired. AuthFill kills that friction. You connect your email accounts once, then whenever you hit a verification field, just click the extension icon. It instantly parses your recent emails, grabs the code (or link), and copies it or opens the link directly in a new tab. Works for: - Email verification codes & magic links - 2FA/OTP codes - Password…

Hey there, there are lot of disposable email services, but as I was thinking I realized 95% of the time, I don't care about my inbox. I just want to "verify my email". That's why I created a startup with no website, it's called [email protected], it's a credible domain (you don't say) and it will click on any "verify" links you send it to it. You can use aliases to get around of duplicate emails in the target system, so like [email protected] [email protected] [email protected] so choose an alias and start using the service! I will provide a…

HappyMail▲201Eight years ago, I was job hunting and felt embarrassed by my Gmail address. I tried registering firstname.lastname — taken everywhere. So I thought: "I'm in IT, I'll set up my own domain with my own IMAP/SMTP. How hard could it be?" A lot went wrong. Forgotten renewals. rocky DNS mistakes. I ended migrating toward Google Workspace, but in the end it felt overkill, having a subscription there plus the whole registrar subscription, and the whole GAFAM sticker on it. Moreover, the final price was way too high for me at the time. Six months ago, someone approached me and related to that…

Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

Mock Fill▲13I got tired of typing the same names, emails, and phone numbers again and again while building/testing forms — usually ending up with gibberish. So I built MockFill, a Chrome extension that auto-detects input fields and lets you autofill realistic mock data in one click (single field or entire form). It’s free, works locally, and doesn’t collect any data. Would love feedback from the HN community

Hey HN, I was tired of writing HTML emails and one day was going through reddit specifically searching for people who hated writing HTML emails and heard a lot of complaints from solopreneurs and marketers as this is a very boring task and many marketers and solo founders have much more important tasks to take care off. So I decided to build HTML email to solve this. My friends have already saved hours using this product. This is my 11th product and I think this solves a problem many folks are struggling with. Feel free to share your views.
