Comparison of software engineering tools and languages

Page content

The Pragmatic Engineer letter published a couple days ago survey statistics of the popularity of programming languages, IDEs, AI tools and other data for mid-2025.

Here I keep some bits that are of interest to me. The full report is quite big and detailed. Please see link to this full survey newsletter below.

most popular programming languages 2025

In this diagram see that the most popular languages are Typescript, Python and Javascript.

We checked similar statistics earlier in Programming languages and frameworks popularity. It showed there that most popular languages were Python, C++ and Java

most popular ai tools 2025

The most mentioned AI tools are Github Copilot, ChatGPT, Cursor and Claude. And Gemini too, ok.

I think those are just most mentioned tools. Out of theese Github Copilot and Cursors are most developer-oriented ones to my taste. And notice, there is no Amazon Q here in the top… See more: AI Coding Assistants Comparison

most popular ide 2025

From this diagram we see the most popular IDEs are VSCode, Cursor, IntelliJ, VisualStudio and PyCharm. This very well alligns with languages popularity: Java/Typescript, Java, C# and Python.

ci cd systems popularity 2025

Most popular tools for continuous integration and delivery are Github Actions and Jenkins. Very easy to believe. Free cloud hosted and free Self-hosted.

version control popularity 2025

Github, Bitbucket and Gitlab. Free, well integrated and selfhosted.

cloud providers popularity 2025

The most popular cloud provider is AWS, then Azure and GCP a bit behind. See also Cloud LLM Providers.

paas saas popularity 2025

The most popular IaaS and PaaS are Vercel, Heroku, Hetzner, Render and Digital Ocean. Not the Oracle with their free tier. Probably too complicated. Or maybe they are in Cloud’s remaining 8%?

Conclusion

Code Typescript or Python in VSCode/Github Copilot or Cursor, host on AWS and use some Github Actions or Jenkins for CI/CD at least.
