Elixir is a functional, concurrent programming language that runs on the Erlang Virtual Machine (BEAM). Released in 2011 by José Valim, it was designed to bring the expressiveness of Ruby to the battle-hardened concurrency infrastructure of Erlang. The result is a language purpose-built for building distributed, fault-tolerant systems that need to stay up no matter what.
In this article, we will walk through what makes Elixir a compelling technology choice, examine which industries rely on it, look at its known trade-offs, and introduce you to the best Ukrainian companies offering Elixir consulting services today.
To be straightforward, Elixir is not among the most widely used programming languages like JavaScript, Python, or Java. However, it consistently ranks among the most admired languages in the developer community. According to the Stack Overflow Developer Survey 2025, Elixir is the third most admired programming language globally, with 66% of developers who use it wanting to continue doing so. The previous year’s survey placed Elixir as the second most desired language to learn, behind only Rust and its Phoenix web framework ranked first in its entire category.
If you are evaluating backend technologies beyond Elixir, it is also worth exploring what a best Node.js development company can offer, or considering Scala development services depending on your data processing requirements.
Why is Elixir gaining momentum? According to Elixir’s creator José Valim, the language reduces the number of infrastructure components developers need to manage from day one of a project. Combined with the Phoenix framework, it can replace the need for a message queue, a separate pub/sub layer, and complex caching solutions all with a single, cohesive toolset.
Industries Elixir Development Can Be Used In
Elixir developers work across a wide range of industries, including real-time communications, fintech, healthcare, media, e-commerce, and IoT. Among the most recognized companies that rely on Elixir in production are Discord, Bleacher Report, Heroku, Pinterest, and Moz. Here are some notable examples of how Elixir has been integrated into real products.
- Discord
Discord is one of the world’s most popular communication platforms. According to the Discord engineering blog, the team chose Elixir from the very beginning because the Erlang VM was the ideal foundation for the highly concurrent, real-time system they were building. What started as a prototype grew into an infrastructure handling millions of concurrent users. Discord later published how they scaled Elixir to 5 million concurrent users and eventually further still, making it one of the most widely cited proof points for Elixir’s production viability.Â
- Bleacher Report
Bleacher Report is a major real-time sports media platform that was processing billions of page views and push notifications per month. Originally built on Ruby on Rails, the platform could no longer scale under those traffic loads. The engineering team migrated the backend to Elixir, drawn by both the Ruby-like syntax, which made the transition straightforward for the team, and the significant performance gains the BEAM runtime provided for concurrent workloads.
- Moz
Moz is a well-known SEO software company that handles large volumes of web crawling, data processing, and API requests. According to a published case study, the team adopted Elixir to handle their processing pipeline more efficiently, leveraging OTP’s supervision model to build resilient background systems capable of recovering from failures automatically.
Challenges That Can Appear With Elixir Integration
Elixir brings substantial advantages to the right project, but it is important to go in with a realistic picture. Here are the core benefits of the language, followed by the challenges teams commonly encounter:
Key advantages of Elixir:
- Massive concurrency out of the box – the BEAM VM supports millions of lightweight processes, as demonstrated by Discord’s engineering at scale
- Built-in fault tolerance through OTP supervision trees, enabling systems that heal themselves after failures
- The Phoenix framework provides real-time capabilities via channels and LiveView with minimal server overhead
- According to the Stack Overflow Developer Survey 2024, Elixir developers report one of the highest median salaries among all surveyed languages a signal of both the language’s complexity and the value teams place on it
- A highly productive development experience thanks to a clear, expressive syntax
Common challenges teams face when adopting Elixir:
- The functional, process-oriented programming model requires a different way of thinking about state and control flow a learning curve for developers coming from object-oriented languages
- The talent pool, while growing, remains smaller than those for JavaScript or Python, making hiring more selective
- Elixir is not designed for CPU-intensive numerical computation; for those workloads, Scala development services or Python may be more appropriate
- The ecosystem, while maturing rapidly, is not as broad as Java or JavaScript in terms of third-party library availability
- Debugging distributed, concurrent systems requires familiarity with BEAM tooling, which has its own learning curve
8 Reasons to Look for Elixir Consulting Services in Ukraine
Outsourcing Elixir development to Ukraine can be highly beneficial for companies of all sizes. Whether you lack internal expertise or simply want to move faster, Ukrainian specialists can help you build and ship with confidence. Here are eight strong reasons why Ukraine stands out.
- Governmental Support of the IT Industry
Ukraine has more than 280 universities, with a significant portion offering technical programs in computer science, mathematics, and software engineering. According to the IT Ukraine Association’s Digital Tiger 2024 report, the country’s IT sector has evolved into a strategic driver of the national economy, with IT service exports reaching markets across 147 countries in 2024.
- High Level of Professionalism
Ukrainian IT professionals work across a wide spectrum of languages and platforms, including Elixir, Erlang, Python, Java, Kotlin, and many others. According to IT Research Ukraine 2024, published by Lviv IT Cluster, the tech sector contributes 4.4% to Ukraine’s GDP a figure that reflects the industry’s scale and professional maturity, not just its headcount.
- Lower Hourly Rates
Hiring a Ukrainian Elixir consultant is considerably more affordable than equivalent talent in the US or Western Europe. According to the Stack Overflow Developer Survey 2024, the median salary for Elixir developers globally sits at approximately $96,000 with rates in the United States averaging well above $115,000 per year. In Ukraine, comparable talent is available at roughly $45,000 annually, delivering genuine cost savings without compromising quality.
- A Large Pool of Experts
According to data published by Ukraine’s Digital State platform, Ukraine’s IT industry employs between 302,000 and 346,000 professionals as of late 2024. Despite ongoing challenges, the tech sector has shown remarkable resilience and continues to grow, underpinned by a workforce with a strong appetite for modern, emerging technologies.
- The Culture of Personal and Professional Growth
Ukraine has a dynamic startup ecosystem that has attracted significant international investment. According to data cited by Alcor, Ukrainian startups attracted a record $571 million in investment in 2021 alone. Homegrown success stories such as Grammarly, GitLab, and MacPaw demonstrate the entrepreneurial energy and technical ambition that Ukrainian developers bring to their work.
- Convenient Location
Ukraine’s position in Eastern Europe places it within a two-to-three-hour flight from most European capitals, according to general geographic data. Even for US-based companies, the time zone overlap during morning and evening hours makes daily collaboration entirely practical, and Ukrainian teams are widely known for their willingness to adapt their schedules to client needs.
- Cultural Similarities
Ukraine shares many professional and democratic values with Western Europe and North America. The IT Ukraine Association describes the country’s tech culture as one defined by accountability, a focus on quality, and a results-driven approach values that align well with the working norms of international clients.
