Why People Trust DesignRush

Rated 4.8 on Google and 4.7 on Trustpilot, the DesignRush Agency Directory is a reliable resource for finding top JavaScript development companies. We owe this to our executive selection team, which follows a strict screening process when featuring agencies on the platform, assessing key performance indicators, like portfolio, client reviews, and industry reputation.

DesignRush rating logos on Trustpilot and Google

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.

JavaScript Development Company Hiring Guide

What is a JavaScript development company?

A JavaScript development company is a company that develops and maintains web applications and software using JavaScript, a widely used programming language for front-end and back-end development. Its expert developers specialize in various JavaScript frameworks and libraries, such as React, Angular, Vue.js, Node.js, and jQuery, delivering intuitive and user-friendly websites.

Businesses often seek the help of a JavaScript development agency to address challenges, such as:

  • Lack of skilled in-house talent
  • Outdated legacy systems in place
  • Limited technical expertise to handle complex projects
  • Tight development timeline
  • Budget constraints in hiring an in-house development team
  • Limited foresight of industry trends and best practices

Hiring JS development services ensures that a business’ website, software, or application has a modernized user interface and provides a seamless user experience. By partnering with a reputable JavaScript development company, businesses can unlock the full potential of their online presence, enhance user satisfaction, and drive growth.

Success story

Our team of experts handpicked this case study to emphasize the benefits of hiring a reputable JavaScript development company to drive business growth:

  • Challenge: FINN, a German-based car company, struggled with organizing its operations and automating its processes as it expands to the US. However, its current subscription system relies on older technologies like manual spreadsheets and emails. The car company needed a partner to transform its internal tools to optimize workflows and make the app easy to navigate for users.
  • Solution: Cheesecake Labs helped FINN’s existing engineering team automate its processes. It also modernized its back end and internal tools by adding key features in its customer portal, allowing users and team members to easily and efficiently perform tasks like ordering or making account changes. Using Node.js, Typescript, and a PostgreSQL database, Cheesecake Labs transformed FINN’s US operations.
  • Results: The partnership resulted in an over 1,200+ increase in subscription for FINN. The internal tools built by Cheesecake Labs also generated significant usage, with a boost of 6,000+ page views per month.

What does a JavaScript development company do?

A JavaScript development company creates web and mobile applications, websites, and interactive user interfaces using JavaScript and its associated frameworks like React, Angular, and Node.js.

  • JavaScript maintenance and support
    Ensuring the ongoing performance and security of JavaScript applications

Success story

This case study showcases the services that enables a JavaScript development agency to deliver exceptional software systems that can contribute to boosted productivity and operations:

  • Challenge: A financial services company wanted a simple, intuitive application to manage resources, tasks, and projects. The goal was to replace Jira and Excel templates with a more comprehensive solution tailored to its specific needs.
  • Solution: DevsData Tech Talent developed a custom-built enterprise resource planning (ERP) system with advanced features, such as automated notifications and report generation. It also features robust encryption and a comprehensive permission system powered by its JavaScript framework tech stacks, namely Vue.js, SSS, Node.js, and Express.js.
  • Results: The partnership resulted in a user-friendly ERP and PM system that perfectly aligned with the client’s needs. The software surpassed Jira in terms of security and processing capabilities, becoming a core tool for day-to-day operations across business departments.

What is the typical timeline for JavaScript development projects?

The typical timeline for JavaScript development projects can take 1 to 12 months, depending on the scope, project complexity, development tools, availability and access to tech stacks and tools, and team location.

To break it down, here’s a general web app development timeline that JavaScript development companies also deploy:

How much does a JavaScript development agency charge for its services?

A JavaScript development agency typically charges between $100 and $250 per hour, depending on the scope, project complexity, seniority of developers, and location.

Here’s a table showing how JavaScript developers charge differently based on where they are based:

Location Price
Europe €55-€125
Central or Eastern Europe €30-€65
India $20-$50

Since JavaScript has different frameworks, costs also differ based on the developer’s expertise, specifically:

Framework expertise Price per hour
Node.js $75-$95
React $70-$90
jQuery $60-$80
AngularJS $85

On DesignRush, the top JavaScript development companies charge an average of $65/hour. 18.3% of JavaScript development agencies accept projects with a budget of under $1,000, offering basic development services. On the other hand, 4.7% of agencies require projects within a budget of over $50,000, offering custom JS development services.

Why should I hire a JavaScript development agency?

You should hire a JavaScript development agency for its technical expertise in the JavaScript programming language, from its core syntax to advanced frameworks and libraries. Beyond technical proficiency, a JavaScript development agency often strongly understands the broader web development ecosystem. This knowledge allows them to integrate JavaScript seamlessly with other technologies, creating cohesive and user-friendly applications.

Moreover, you should hire a JavaScript development agency because it:

  • Has seasoned programmers with proven expertise in JavaScript
  • Deploys efficient development processes to reduce development time
  • Mitigates common risks in the development process
  • Helps your website reach a wider audience by optimizing your website
  • Increases productivity for faster time to market
  • Improves customer experience through a well-designed and functional website

Success story

In this case study, our experts highlight the importance of choosing an agency with comprehensive skills and experience in JavaScript frameworks to transform innovative ideas into impactful applications:

  • Challenge: AskIris, a healthcare mobile application, wanted to address the challenge of hospitals’ inefficient supply rooms, where nurses and other medical professionals spend significant time searching for necessary supplies.
  • Solution: Designli developed the minimum viable product (MVP) by prioritizing easy-to-implement features using CSV workflows. To accommodate various hospital systems, the JavaScript development agency designed a customizable solution where hospitals can tailor the app to their specific needs, ensuring a seamless fit with their existing infrastructure. Designli used JavaScript frameworks like AngularJS and NodeJS, along with the cross-platform capabilities of Flutter to enable a scalable backend and a versatile app.
  • Results: The collaboration resulted in a successful working relationship between the AskIris and Designli teams, delivering the features needed for the app within budget and on time. With the successful deployment of the app, the client saw tangible improvements in a hospital’s supply room efficiency and streamlined inventory management.

How do I choose the best JavaScript development company for my business?
