Hi HN! I made a really quick web app to help people validate their ideas. The app is a simple landing page builder, but every page includes a really simple Yes/No "Are You Interested?" poll. Every vote is recorded and tracked, and if they click yes they are brought to a page where they can submit an email. This makes validating ideas super easy because you can post your link to different communities and get statistically significant results as well as build an email list. Given an hour, you could easily create 50 different landing pages and be able to validate your ideas in bulk. The…

http://www.upboat.us Demo: http://www.upboat.us/idea/upboat Screenshot of logged-in view: http://i.imgur.com/vUZXfZc.png Upboat is an idea validation platform, somewhere inbetween Kickstarter and LaunchRock. If the idea you pitch receives over 200* "upboat"s (consented would-be users) within one week, you get the whole emailing list of all those who upboat'd it. If not, you get nothing. This is helpful for those who have ideas for side-projects, but lack the strong-enough incentive to get to work and just hack something together. Should you put up…

Hello! I just wanted to share my very first project I decided to open source. It's (yet another) form validation library for React. https://github.com/adbutterfield/ez-react-form-validator I built it because I've never really liked Formik or React Final Form. Both seemed a bit overkill for most of my projects. I tried React Hook Form on a project recently, but it wasn't really my cup of tea either. Not sure if other people will find this form validator useful. But I'm putting it out there just in case. I also did want to give a quick shout out to the contributors of the…
