The results of our fifth annual Developer Ecosystem Survey are in! The report tracks the current trends around various programming languages, applications, tools, frameworks, and even developers’ lifestyles and habits.

What’s different about this year’s report is that this year we improved our methodology and extended the survey geography to the whole world!

The State of Developer Ecosystem 2021 report is based on the input from 31,743 developers from 183 countries and regions that helped JetBrains map the landscape of the developer community.

Here are some interesting findings:

  • JavaScript is the most popular language – 69% of respondents used it in the last 12 months, while 39% named it their primary programming language.
  • Python is more popular than Java in terms of overall usage (52% vs 49%), while Java is more popular than Python as a main language (32% vs 29%).
  • The 5 fastest growing languages are Python, TypeScript, Kotlin, SQL, and Go.
  • More female developers are coming to the tech industry – women are more likely to be involved in Data Analysis and Machine learning or UX/UI Design/Research, but less likely to work in Infrastructure Development / DevOps, System Administration, or Deployment.

Over the past year, the whole world has shifted to remote work. Both the market and the daily life of developers have been impacted:

  • 66% of the respondents now use video conferencing, up from 43% last year.
  • The market of video conferencing tools has changed a lot: Zoom, Microsoft Teams, and Google Meet have gained a lot of users, while Skype has been losing them dramatically.
  • More tools have introduced cloud solutions, and the usage of cloud versions has doubled in the last 4 years.
  • In early 2020 about 70% of developers worked from the office. Now 80% work from home.
  • In 2020, most developers reported programming as their biggest hobby. This year video games are topping the list, increasing in popularity from 49% to 59%.


These infographics represent the key insights we’ve been able to glean from the survey data. If you’re interested in learning more, stay tuned for the complete results along with the anonymized raw data!

We highly appreciate the input of everyone who took part in the survey. It is an invaluable source of information about the developer community. and it provides us with great ideas for improving our products, too. Thank you!
