      Mobile App Development Review from Mica Palmer

      They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project.The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

      eCommerce Development Review from Devul Nahar

      We needed help designing the Frontend pages on my website. Also some design work. Everyday I would assign my Frontend developer some key tasks and deliverables. He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional. They had great professionalism, good talent, and good support.

      Web Design Review from Patrice Archer

      They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

      Our first engagement with Twenty Ideas was accurately scoped and allocated from day one, and that was impressive. Being on time and budget while exceeding expectations seems impossible for many vendors, but with Twenty Ideas, there were zero issues. They anticipated our needs and presented clear options when necessary.

      The most impressive thing was the collaboration we established. I had been creating this app by myself for so long, and all of a sudden, I had a whole team of thought partners. Twenty Ideas really got in there with me, learned what I was trying to make, and collaborated with me on it. It was an extremely rewarding experience, and we're thrilled with the app!

      I started working with Twenty Ideas in a part-time consulting capacity, but I became so taken with the team’s passion, mission, and supportive culture, that I ended up applying for a full-time position. I’ve been with the team for three and a half years now, and it’s given opened doors to expand my skill set; work with smart, kind, and dedicated people, every day; and work with clients who truly care about making a positive impact, to create life-changing solutions together. It’s a great place to work!

      Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.

      Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

      I worked at Decode for about a year, and during that time I had the chance to meet many wonderful colleagues who helped me grow professionally and learn new skills. Because of the nature of my role, I also had the chance to collaborate with clients across Europe, the USA, and the Middle East, and even visit some of them in person.The team I worked with was everything you could hope for - driven, proactive, and always willing to jump in and help. The development teams I was part of were well-balanced in both skills and personalities, led by highly experienced engineers who lead by example.Beyond the projects themselves, the company culture stands out. People are friendly, and the leadership is focused on sustainable growth while supporting employees development. Decode isn’t afraid to promote talent and encourage people to step outside their comfort zones in order to grow.The office is also in one of the best business neighborhoods in Croatia, with plenty of variety for employees nearby.Overall, I highly recommend Decode as a great place to work!

      Working with DECODE has been a great experience so far! Their team is skilled, flexible, and always open to collaboration, which makes the process smooth and enjoyable. Their modern design approach aligns well with our vision, and they show a real commitment to delivering a strong final product.What we particularly appreciate is their willingness to engage and adapt as the project evolves. While some aspects require additional clarification along the way, they are always receptive to feedback and ready to adjust accordingly. The overall working atmosphere is positive and professional, making them a great partner to work with. Looking forward to the second half of our project!

      The AppIt team has been a project-saver for our company. I went with AppIt because I was looking for a trustworthy, transparent partner to guide me (an app-dev newbie) through building a new feature for our mobile app. Their quality of work, customer service, ability to meet timelines, and transparency has been phenomenal. Highly recommend Kayla and the AppIt to any company needing development help.

      As fellow Colorado Companies to Watch winners, our team met Amanda and her team in 2022 and its been a match made in heaven! We have our own in-house development team that is swamped with working on our web application, Kanso, and did not have the bandwidth to work on sub-applications and portals. Here's where AppIt came in to save the day!We are closing out our first project with AppIt, and we are more than impressed. The application is clean and beautiful. Their team has been a joy to work with and I look forward to our check-ins on progress. This project has been so successful we have lined up a handful projects to continue this business relationship.Kanso Software is very grateful for AppIt!

      I have worked with AppIt Ventures on two different enterprise size solutions. Throughout my career and have worked with several development teams. AppIt Venture stands out above the rest.The extraordinary service provided by AppIt Ventures starts at the top, with their CEO Amanda, and is executed throughout the entire team. It’s clear their employees are empowered to make decisions, take care of their customers, and provide the customer service their leader promotes.Kayla, our outstanding project manager is creative, reliable and detail-oriented offering guidance and support to ensure all of our development’s needs are on track and being done with our greater vision and application needs in mind. If any bugs pop-up, which is bound to happen, AppIt's team is on it and has the issue quickly fixed or a solution put into place within hours. With AppIt's development team, I have peace of mind knowing we can quickly and easily adjust to our customer's requests and provide an unparalleled customer and participant experience.I highly recommend using AppIt Ventures and look forward to continuing my partnership with them.

Frequently Asked Questions About React.js Developers

What are the typical React.js development services?

React.js development companies provide end-to-end services that span the entire software development lifecycle, from strategy and design to development and launch. Core services include: 

  • React.js consulting: Guiding businesses on building and optimizing their React applications through component selection, architecture design, and roadmap development. 
  • Custom React.js development: Engineering applications tailored to a business's specific needs, goals, and existing IT infrastructure, and typically include web design and web development.  
  • UI/UX design: Delivering intuitive interfaces, clear user flows, and standardized design systems that align with a brand and its target users. 
  • API integration: Connecting the React frontend to back-end systems, third-party tools, and external data sources to support seamless functionality and user experiences. 
  • Platform migration: Rebuilding or migrating legacy frontends to React to improve maintainability, usability, and performance, often with minimal disruption. 
  • Maintenance and support: Providing post-launch monitoring, debugging, performance optimization, and technical support. 

Many React.js developers also offer specialized expertise, including SaaS products, web application development, customer portals, eCommerce solutions, and minimum viable products (MVPs).  

Some React.js development companies may also offer digital marketing services, such as content marketing, search engine optimization (SEO), and branding. 

What is the difference between React and React Native?

The main difference is that React is used to build web user interfaces, while React Native is for developing mobile applications. Here are more details on their differences: 

 ReactReact Native
Primary platformsWebsites, web applications, and single-page applicationsiOS and Android mobile apps
Tech baseJavaScript/TypeScript with React for web UIJavaScript/TypeScript with React, rendered through native UI components
Best forBusinesses building browser-based products, customer portals, dashboards, eCommerce sites, and SEO-focused web experiencesBusinesses building cross-platform mobile apps for both iOS and Android with shared logic and accelerated development time
ExamplesFacebook, Instagram, Netflix webMicrosoft Teams and Shopify

What are the typical React developer tools?

React.js developers typically choose their stack based on a client's product goals, technical requirements, and existing systems. For example, they may use Formik for complex forms and validation, Storybook for developing and testing components in isolation, and MUI for production-ready UI components and design systems. 

Common React developer tools: 

  • Core front-end: React, JavaScript, TypeScript, HTML, CSS 
  • State and data fetching: Redux, TanStack Query 
  • UI and styling: Tailwind CSS, MUI, Storybook 
  • Testing: Jest, React Testing Library, Cypress 
  • Back-end options: Express, Laravel, Rails, ASP.NET 
  • Databases and infrastructure: PostgreSQL, SQL Server, Redis 

Can React.js developers build AI-powered features into web applications?

Yes. A React.js developer can build AI-powered features into a web application by integrating model APIs, SDKs, and AI workflows into the product experience.   

Depending on your goals, this may include providers such as Google Gemini or Anthropic Claude, along with React developer tools, like Vercel's AI SDK for building chat, search, recommendation, and automation experiences in React-based apps. 

These companies can help you build features such as: 

  • Personalized content and recommendations based on user behavior 
  • Chatbots and virtual assistants for real-time customer support 
  • Smart search with autocomplete, semantic search, and related-result suggestions 
  • AI-assisted dashboards that generate summaries, reports, forecasts, and insights from business data 

When should you hire a React.js development company instead of using an in-house team?

The right choice depends on your project goals, internal capacity, timeline, and need for control. You may want to hire a React.js development company if: 

  • You have a short-term or time-sensitive project, but your internal team is already at capacity. 
  • You do not have the specialized expertise required for the project, such as React architecture, performance optimization, migration, or AI feature integration. 
  • You need to accelerate delivery without hiring and onboarding a full internal team. 
  • You want access to a broader range of skills, such as design, front-end engineering, QA, and post-launch support, through a single external partner. 
  • You need temporary support to fill skill gaps or expand delivery capacity. 

Use an in-house team when: 

  • The application is a core business product that requires long-term ownership and deep institutional knowledge. 
  • The project involves highly sensitive systems, proprietary logic, or strict security and compliance requirements. 
  • You need close day-to-day collaboration, faster internal feedback loops, and direct control over priorities. 
  • The product requires continuous iteration and alignment with multiple internal teams over time.
