Ever wondered which is the most demanded programming language in 2025? Although there are more than 200+ programming languages, only few of them are used in the real world industry. Knowing this information is essential to succeed in the developer job industry.
During 2025 (from Jan-2025 to Dec-2025), DevJobsScanner has analyzed nearly 3M developer jobs. From those jobs, DevJobsScanner has only picked the job offers that explicitly required a programming language. See section How has this study been made to know more information about it.
Keep reading below to know which languages are the most demanded 👇
1 - JavaScript / TypeScript
Since its creation to make the firsts websites dynamic, JavaScript hasn't stopped gaining popularity over the years. With that being said, JavaScript remains the most demanded programming language in the entire market in 2025. The arrival of TypeScript (a JavaScript superset with type safety) has also helped to cement this position. TypeScript popularity has only increased in recent years. Many modern JavaScript frameworks are entirely written with TypeScript, like Angular or NestJS.
During 2025, we have found 162K job offers that represent ~30% of the jobs that explicitly required JavaScript or TypeScript as a programming language.
- Jobs Found: 162K (~30%)
- Keywords: JavaScript, TypeScript, React, Angular, Vue, Node.
2 - Python
Python continues to hold its place as the second most demanded programming language in 2025. Its versatility, from scripting, running servers or for data analysis, has been key to achieving this milestone. The ongoing AI and machine learning boom has further strengthened Python's position, as it remains the dominant language in those fields. Python also has one of the greatest and biggest communities out there.
During 2025 we have found 108K job offers that account for a total of ~20% of jobs that explicitly required Python as a programming language. Notably, Python's share grew steadily throughout the year, climbing from around 21% in January to over 26% by December.
3 - Java
In the top three spot, as the third most demanded programming language, we find Java. Java language has been really popular since its creation in 1995. Even though this popularity has been decreasing over the last years with the appearance of more modern languages like Kotlin, it still holds a solid top three spot. Frameworks like Spring, used in many top tier companies, are helping to hold that position.
During 2025, Java accounted for ~17% of demand with 89K job offers found, holding steady throughout the year.
4 - C#
The top four spot goes to C#. C# is a general purpose, multi-paradigm, object-oriented programming language, created mainly to address some of the weaknesses of C++. As a general purpose language, C# has a wide range of use cases. The most common usage of C# is with the .NET framework. It is also heavily used in the Unity game framework for scripting. Both .NET framework and Unity are popular among top tier companies.
C# accounts for ~10% of the overall job market demand and has remained relatively stable throughout 2025. Over this period, we identified more than 52,000 job listings specifically requiring C# skills.
5 - PHP
The language that started nearly three decades ago as a simple "Personal Home Page Tool", hence the name PHP, has made an incredible journey since then. PHP is the fifth most demanded programming language in 2025. During the year, PHP accounted for ~7% of the total demand for developer job offers. Its share showed a notable decline through 2025, starting near 10% in January and settling around 4% by year end.
PHP is mainly used for web development, in conjunction with frameworks like Laravel or Wordpress.
6 - C/C++
Fifty years have passed since the first release of C, and the later appearance of C++, which was firstly named "C with Classes". In this long window of time, C/C++ has maintained its popularity with regular additions and improvements to the language. Modern C++ includes object-oriented, generics and also functional features. It also facilitates low level memory manipulation. Its usage in the industry is widely extended, C++ can be found on video games, servers, databases, space probes and many others.
During 2025, C/C++ held a steady share of around 4-5% of the job market, with 24K job offers found over the year.
7 - Ruby
Ruby holds the top seven most demanded programming language with 14K jobs found (~3% from the total job demand). Its most popular usage comes in conjunction with the web framework Ruby on Rails. Even though top seven may not seem much, Ruby runs some of the top tech companies nowadays, like Shopify, Github or GitLab.
Ruby's job demand has held steady at around 3%, showing consistent stability over time. Despite being a more niche language compared to others, its presence in the job market remains reliable.
- Jobs Found: 14K (~3%)
- Keywords: Ruby, Ruby on Rails
8 - GO
Go is a young language created by Google to improve programming productivity in an era of multicore, networked machines and large codebases. Top tier companies like Uber, Twitch and Cloudflare are using Go.
During 2025, demand for Go held steady at around 2-3% of the market. We identified a total of 13K job opportunities requiring Go over the year, making it the eighth most demanded language.
- Jobs Found: 13K (~2%)
- Keywords: Go

How has this study been made?
The main objective of this study is to categorize the "dev jobs" by its programming language, minimizing the errors and getting the most accurate information possible. To achieve that, only the title has been used to categorize those jobs into programming languages. This is because we want just the jobs that explicitly require a programming language.
For example, a job with the title "Backend developer", even it has stack defined and also description with job requirements, is discarded and does not count for any language. Otherwise, a job with the title "React Developer" would count as JavaScript / TypeScript, and likewise a job with the title "Laravel Developer" would count as PHP.
It is also important to note that one job offer can count for 2 or more languages. For example a job with the title "Full Stack Developer (Django/Angular)" will count for languages Python and JavaScript / TypeScript.
Summary
It's clear that JavaScript and TypeScript really dominate the developer job market. JavaScript and TypeScript account for a total of ~30% of the job offers that explicitly required a programming language. This is huge, meaning that nearly 1 out of 3 job offers required JavaScript or TypeScript knowledge.
Python and Java are the second and third most demanded programming languages in 2025 with a great number of job offers also. The gap between them remains significant, with Python holding roughly 3-4% more share than Java across the year, and Python's demand notably accelerating through the second half of 2025 on the back of AI and data science hiring.
C#, PHP, Ruby, and Go have all demonstrated a relatively consistent job demand, indicating that each of them could be a reliable choice as a programming language.
On the other hand, PHP demand declined notably during 2025, dropping from around 10% in early 2025 to roughly 4% by year end. This decrease is worth considering when deciding which programming language to focus on for job opportunities.
