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.

Click on a ticker to get all the relevant information:

It doesn’t look super sexy, but it’s easy to use.

If you’d like to use it, you can access it here.

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