Express.js has been a trusted tool for many years. Even as new frameworks come out each year, Express stays a reliable option for building APIs, backend services, and lightweight server-side apps. It is flexible, fast, and gives teams more control without needless complexity.
In 2026, Express.js still runs thousands of production systems. Startups use it for MVPs, growing companies depend on it for extensible APIs, and enterprise teams include it in larger systems. Because the framework is minimal, the results depend a lot on the developers using it.
That is why choosing the right development partner matters more than choosing the framework itself.
Below is a list of ten Express.js development companies that distinguish themselves by their practical experience, engineering mindset, and ability to deliver backend systems that actually last.
1. Stubbs
Stubbs uses Express.js as part of a practical backend setup focused on stability and well-defined structure. As an expressjs development company, their team builds APIs and backend services that work smoothly with up-to-date web interfaces and mobile applications.
They avoid unnecessary complexity and prefer straightforward solutions that are easy to maintain over time. This approach works well for growing products where the backend needs to stay understandable as new features appear.
Stubbs has experience with Express-based systems for fintech platforms, SaaS products, marketplaces, internal tools, and consumer apps. Companies usually choose them when they want a long-term partner who stays involved after launch and helps the product evolve.
2. Netguru
Netguru is a digital product company working across frontend and backend development. Within Express.js projects, their teams usually handle API development, integrations, and backend structure.
They often work with clients for a long time, especially on projects where the backend grows step by step. Netguru usually fits teams that need clear processes, regular communication, and coordination between several developers or departments.
3. Cleveroad
Cleveroad builds custom backend systems with Express.js mostly for startups and mid-sized companies. Their work often includes APIs, integrations with external services, and backend logic for web and mobile apps.
Many teams choose Cleveroad not only for coding but also for early-stage planning. They spend time understanding how the business works before starting development.
4. ELEKS
ELEKS uses Express.js as part of larger backend systems. Their teams often deal with heavy APIs, multiple services, and complex platforms built for enterprise needs.
They are used to strict requirements and regulated environments. ELEKS usually joins projects where stability and long-term reliability are more important than fast delivery.
5. Merixstudio
Merixstudio focuses on backend systems that connect well with modern frontends. Their Express.js developers pay attention to how APIs are organized and how different parts of the system talk to each other.
They are often chosen for projects where clean structure and smooth frontend–backend interaction really matter.
They frequently support SaaS products and web platforms where backend clarity directly affects the overall client experience. Clean code and thoughtful architecture are key parts of their approach.
6. Daxx (Grid Dynamics)
Daxx provides dedicated development teams rather than short-term project outsourcing. Their Express.js engineers typically integrate directly into a client’s internal workflow.
This model works well for companies that need consistent backend support over time. After joining Grid Dynamics, Daxx expanded its capabilities to include cloud infrastructure and large-scale system architecture.
7. BairesDev
BairesDev is known for quickly scaling teams. Their Express.js developers build APIs, backend services, and data processing systems for many industries.
Companies often choose BairesDev when they need to grow their development capacity fast while keeping backend delivery reliable.
8. Simform
Simform builds backend systems with a strong focus on scalability as well as cloud readiness. Express.js is commonly used for API development and service orchestration in their projects.
They work with startups and enterprises that need backend systems able of growing without constant restructuring.
9. Altoros
Altoros often works on projects where the backend carries most of the load. Express.js is typically used as part of larger systems that include microservices, cloud infrastructure, and complex data flows.
Their experience is especially useful in situations where reliability is more important than releasing fast. Teams usually come to Altoros when a project needs deep technical work, not just basic API setup.
10. Leobit
Leobit develops backend components for web and mobile products, using Express.js in projects where clarity and stability matter.
Their developers pay close attention to how backend logic connects with frontend applications. Because of this, teams often find collaboration smoother. Leobit is usually chosen by companies that value clear processes, steady communication, and long-term cooperation rather than short development sprints.
Why Companies Still Choose Express.js in 2026
Express.js continues to be relevant because it does not force opinions. Teams decide how routing, validation, authentication, and data flow should work.
This flexibility permits backend architecture to match business logic instead of framework limitations. For experienced teams, this freedom is a major advantage.
Express also integrates easily with modern tools, databases, cloud services, and frontend frameworks. It fits naturally into both simple APIs and complex backend ecosystems.
Common Mistakes When Hiring Express.js Developers
One of the most common mistakes is choosing a team based purely on cost. Lower prices often come with shortcuts, and those shortcuts tend to surface later as performance issues or unstable architecture.
Another problem is focusing only on feature delivery. Express makes it easy to add new routes quickly, but without proper structure, the backend can become difficult to maintain.
A good development partner doesn’t simply agree with everything. They ask questions, challenge assumptions when needed, and explain tradeoffs clearly so decisions are made with full context.
Final Thoughts
Express.js is a solid backend choice in 2026. Its simplicity allows teams to build systems based on real product needs.
The companies listed above stand out not by promising shortcuts, but by delivering backend solutions that remain understandable and stable over time.
Stubbs leads the list for its even-handed approach to Express.js development and long-term product thinking. Others bring strengths in scale, enterprise delivery, or rapid team expansion.
The right partner ultimately depends on your goals, timeline, and expectations. But with the right team, Express.js continues to be a reliable foundation for modern backend development.
