I became possessed with the idea of a mobile-friendly web-app that would allow you to create Instagram-worthy image posts super quickly. The technical solution came to me from the beginning: the user inputs text, which is rendered in a square, the user selects a background image supplied via the Unsplash API, and then the app exports the Vue component into an image. I put it together initially a component in the CMS for my personal site, then realized after showing it to a few friends that it had potential as a mini-SaaS, so I spent a couple of days refactoring it as a standalone app. And now here we are! http://postmaker.platformkit.com/
I will probably get a domain for it this week.
Auth0 for login, Github as the backend. Built in Vue/Gridsome. Deploys to Netlify.
Currently there are no restrictions, everything is free. In the future, if there turns out to be a market, I will add a paid tier.
Future features I'm already considering (just to scratch my own itch) -- publish to RSS / schedule posts for the future.
