24 alternatives to Autheona (v2)
Over the last few months, I’ve been working on an API to prevent fake sign ups for one of my SaaS products. Later I decided to turn it into a standalone API. You can use it to prevent most fake sign-ups for your own products. It includes over 142K+ disposable domains (with an open claw agent that runs daily to identify new ones), fraud detection, typo correction, error handling, and custom rule management to fit your specific use cases. and here's the link: autheona.com I hope you give it a try. Cheers!

LoginLlama▲95Hey HN I recently rebuilt my microsaas Loginllama. It uses the same stack but I've made the API much much better and it's now a product I'm happy to promote. As with most developers I hide behind building instead of marketing. As this a developer focused product, this is me marketing! It's a product built in anger for myself when I had to implement a similar system for a number of clients. I released it as I assume that other people had the same problem. There are SDK's available for Nodejs, PHP and Python. Auth0 and Wordpress integrations are coming soon. Let me know what you think and if…

SaaSCurate▲36I am an indie hacker and have been launching my products on Product Hunt. Like many of you here, my experience with PH sucked: Lots of bots. Hard to compete. There's also been many new launch platforms coming up, but all of them make you compete for upvotes. Ugh. So I have been working on something different: https://saascurate.com/ It's a community-driven platform where indie hackers and SaaS founders help each other grow their products. The idea is simple - list your product, engage with other founders, gain exposure and social proof. No upvote system. It's hard and…

Users within our ICP were dropping off during or right after the signup process, never reaching that crucial “aha moment” where they truly see the value in our product. Typically, this moment happens when they’ve created an interactive demo they’re happy with. We were like... "let's just do it". So, we decided to ungate our product—removing the signup step entirely at this stage of the user journey. Of course, users can still sign up if they want to continue using the product, but our aim was to reduce friction and align with the supposed future of product-led growth, where ungated…

Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…
