It's not that it's a barrier, but it's unclear that you need an account before being able to use the site. I clicked on the PostgreSQL and Elasticsearch buttons a few times, the page seemed to flash for a second and then... nothing. But as [lifekaizen explained](https://news.ycombinator.com/item?id=24569307 https://news.ycombinator.com/item?id=24569307), no signup with then the option to save when signing in would be even better.
