How big is the software development tools market worldwide in 2020?
Does anyone know up-to-date numbers? I can only find this for 2012-2016. https://www.gartner.com/en/documents/2098416
Check out the Stripe Developer Coefficient report, that is telling from one vantage point. You might also consider https;/coss.media as a subsector. What about tools that help with digital transformation or cloud development?
I'm not sure there is a single report, you more have to hobble things together from various sources.
