A Free Interactive IPO Calendar

I felt like doing something a little more lighthearted than usual.

The calendar highlights past and upcoming IPOs within a given date range. The data for the IPOs is sourced from a free endpoint of the finnhub.io API.

It’s built on the R Shiny framework.

If you’d like to build it locally or develop it further, you can find the source code and build instructions here.
