React powers our own production products

React development for dashboards and web apps

We build React interfaces for everything that lives behind a login: dashboards, CRMs, internal tools and customer portals. If what you need is a site that ranks on Google, we’ll point you to Next.js instead.

When spreadsheets and plugins stop cutting it

These situations usually call for an interface of your own, built around how your team works:

  • Your team juggles three tools at once and copies data between them by hand.

  • Each customer needs to log in and see their own information, and only theirs.

  • Several people edit the same records and need to see changes instantly, without refreshing.

  • The admin you have works, but nobody wants to use it on a phone.

  • Your business rules (statuses, permissions, approvals) don’t fit into a generic form.

What we’ve built with React

Our multi-client CRM is a React application (on Next.js) running in production: each company logs in under its own brand, watches new leads arrive in real time and sees which channel each one came from, from Google and Meta to AI assistants like ChatGPT. Our client admin panel, which we use to manage accounts and users, and the visual editor behind this very website are React interfaces too. These are our own products, shown as technical evidence rather than client case studies. We haven’t published a client project built on plain React yet; when we do, it will be here.

Plain React or Next.js: which one fits your app

Both use React. The difference is where the page gets built and how much search matters.

  • Where the UI is built
    In the user’s browser, starting from a nearly empty HTML file.
    Google and social previews
    They see little content without extra work; irrelevant if everything sits behind a login.
    Deployment
    Static files on any CDN or host, plus whatever API it calls.
    Routing and data
    Chosen and wired up separately, for example with React Router.
    Best for
    Dashboards, internal tools and apps that live behind a login.
  • Next.js

    Where the UI is built
    On the server or at build time, then made interactive in the browser.
    Google and social previews
    They get the full page; built for content that needs to rank.
    Deployment
    Vercel or a Node.js server; it can also be exported as a static site.
    Routing and data
    Built in: file-based routing, data loading and caching.
    Best for
    Public sites, stores and products that mix public pages with a logged-in area.

Since 2025, React’s official docs recommend starting with a framework or a build tool like Vite; Create React App is deprecated. Our own products run on Next.js because they mix public and private pages.

What we build with React

Interfaces for getting work done, not for ranking.

  • Operations dashboards

    Tables, filters, statuses and bulk actions so your team can run the business without spreadsheets.

  • Customer portals

    Each customer logs in to see their orders, documents or reports, with role-based permissions.

  • Real-time data

    Changes show up for everyone instantly, like the leads that land in our CRM.

  • Your backend, connected

    We integrate with your existing API or build a new one, and use services like Supabase or Firebase for auth and data.

  • Reusable components

    An accessible, consistent component library, so every new screen costs less than the one before.

  • Mobile-ready

    Screens that adapt to phones and, when it helps, install as a progressive web app (PWA).

How we build a React application

  1. 1

    Workflows before screens

    We map who uses the app, what tasks they do and what data they need at each step.

  2. 2

    Clickable prototype

    We test the main screens with the people who will use them before writing the business logic.

  3. 3

    Data and permissions

    We define the data model, roles and authentication; if you already have a backend, we plug into it.

  4. 4

    Ship in slices

    We release module by module, starting with the workflow that saves your team the most time.

  5. 5

    Testing and operations

    Automated tests for critical flows, error monitoring and database backups.

    We've worked with Crece Virtual on several web design projects for our Barranquilla operation. Their team demonstrated a solid command of both WordPress and React, adapting to the specific needs of each project based on our technical and functional requirements. What we value most is the quality of the codebase they deliver. Each project has a clean and well-organized structure, which has greatly facilitated updates and the addition of new features when needed. The technical documentation they provide is clear and useful for our internal team. Communication throughout the entire process was smooth and professional.

    Working with Crece Virtual transformed how we acquire clients. From the outset, they understood our business and guided us through everything: digital strategy, website architecture, and domain selection. The WordPress site, with a custom theme and widgets created in Elementor, turned out exactly as we needed: fast, clear, and designed to make requesting quotes effortless. Thanks to technical SEO, link building, and Google Ads campaigns in Medellín, our quote requests increased several times over, stabilizing at nearly 500% higher than at the beginning. The automation that sends leads from WhatsApp to Google Sheets, complete with all the data and UTM parameters, allows us to better measure sales and repeat purchases. Furthermore, their hosting, domain, and Google Workspace services have been reliable, and whenever we need support, they're always there with quick and clear answers.

    We have been working with Crece Virtual for several months now, and it has been a great experience. They built our website in Next.js, and it turned out super fast and professional. The best part is that they didn't leave us on our own after delivery: every month they make updates and improvements, and when we need something urgently, they always respond very quickly. Their support has been impeccable. In addition to the website, they manage our Google Ads campaigns and SEO. Honestly, everything has worked very well. The campaigns bring in good leads and have us well positioned on Google and Bing. They are very professional but also very approachable, always explaining everything clearly. I recommend them without hesitation.

React FAQ

React or Next.js?

If the app lives behind a login and doesn’t need to show up on Google, React with Vite is simpler to deploy and maintain. If it combines public pages that need to rank with a logged-in area, Next.js gives you both in one project.

When is React the wrong choice?

When what you need is a brochure site or a blog: WordPress or Next.js gets you there with less effort. It’s also the wrong move if your team already maintains an Angular or Vue app and there’s no strong reason to switch; rewrites cost more than they look.

Can you hook it up to our existing backend?

Yes, as long as there’s an API (REST or GraphQL) or a database we can reach securely. If there isn’t one, we build it with Node.js or use services like Supabase for auth, data and permissions.

Can you take over a React app another team built?

Yes. We start by reviewing the code, the dependencies and how it gets deployed, then tell you what to keep, what to update and what to rebuild before adding new features.

Can React work for a mobile app?

With React we build web apps that work well on phones and can be installed as PWAs. For a native app in the App Store or Google Play there’s React Native, but we haven’t published a native app case study yet.

Can you work alongside our US-based product team?

Yes. We work remotely from Colombia, which stays on UTC−5 all year, so we share most of the workday with teams on Eastern or Central time. We can follow your repo conventions, code reviews and sprint rhythm.

Does your team need a tool of its own?

Tell us which process you want to fix, who would use the tool and what systems it has to connect to. We’ll tell you whether React, Next.js or an off-the-shelf product makes the most sense.

It helps to know how many people would use it, what data it handles and whether you already have an API or database.
