How we decide what to build with
Tool choices are not ideology. They follow what your team can maintain, what your product needs, and how fast you want to move. This page explains the frameworks and platforms 63 Bits LLC works with day to day, and the situations where each one is the right call.
If your project already has a stack, we will work within it where it makes sense. Bring your existing systems, hosting preferences, and internal skills to the first call — those narrow the options faster than a feature list does.
The stacks, and where each one fits
Nine tools we reach for most often, in the order we usually reach for them. Read the row that matches your project; the deciding factor is almost always your existing codebase and your team's skills.
Product UI
React & Next.js
React is a component-based library for building user interfaces, created and maintained by Meta. It lets a team assemble screens from reusable parts and keep the UI predictable as state changes. Next.js is the usual production companion: it handles routing, server rendering and the build pipeline that a plain React setup leaves to you. For a business site that needs both marketing pages and an authenticated app area, this pairing covers both without a second framework.
Server
Node.js & Express
Node.js runs JavaScript on the server, which means one language across a project's front and back end. Express is the minimal web framework on top of it: routing, middleware, and not much else. That leanness is a feature when you need an API, a prototype, or a lightweight service rather than a full enterprise framework. For a customer portal or an internal tool, an Express API behind a React front end is often the whole architecture, and it is straightforward to hand over to a new developer.
Mobile
Flutter & React Native
Flutter is Google's UI toolkit for natively compiled applications. It builds for iOS, Android, web and desktop from one Dart codebase, and it renders its own interface components, so screens look the same across devices. React Native is the other cross-platform route, and it fits teams already invested in React, where shared logic between a web product and a mobile app can be a genuine saving. Neither framework is universally better; the deciding factor is usually your existing codebase and your team's skills.
Android
Jetpack Compose
Jetpack Compose is Google's declarative UI toolkit for Android, built into Android Studio and the Kotlin workflow. It replaced XML-based layout construction for new Android interface work, and it changed how screens are built: you describe the UI as a function of state rather than assembling a view tree by hand. We use it for native Android work where platform behavior matters. If your product is Android-first or needs deep system integration, this is the current path.
Content
WordPress
WordPress is an open-source content management system behind a large share of the web. Themes, plugins and custom development make it flexible enough for corporate sites, blogs and content-heavy builds, and its hosting and plugin ecosystem means you are rarely stuck for a solution. It stays relevant for one simple reason: editors know it. If your team publishes regularly, a well-configured WordPress install with custom fields beats a bespoke CMS nobody wants to learn.
Design
Figma & Framer
Figma is a cloud-based interface design and prototyping platform. It supports design systems, comments, developer handoff and prototyping in one file, which is why it became the shared space between design and engineering on most of our projects. It also handles whiteboarding and early product planning, so the thinking and the output live in the same place. Framer takes a different angle: building interactive websites and prototypes where the design itself is close to the published result. It suits landing pages and motion-rich presentations, and it appeals to designers who want fast iteration without a heavy engineering cycle.
Delivery
Docker
Docker packages an application and its dependencies into a container, so it runs the same way wherever it is deployed. It standardizes development, testing and production environments, and it is common in CI/CD pipelines and cloud deployments. The practical benefit is handoff. A containerized project is easier to move between teams, and the old "it worked on my machine" conversation stops coming up.
Choice
Choosing your stack
If you have an existing codebase, we start there and change only what needs changing. If you are starting fresh, the questions are: who maintains this, what does it integrate with, and how often will it change. A content site and a real-time dashboard point to different answers.
Design and engineering
One workflow from the first screen to the first deploy
Figma files, component libraries and prototypes sit next to the codebase, so design decisions and implementation stay in step. Interface design, mobile apps and web development run through the same review, which is how a screen that looks right in a prototype survives contact with real data.
Work within the stack you already have
Most teams arrive with something already running — a WordPress site, an internal tool, an app shipped two years ago. We review the codebase before proposing anything, then say plainly whether we can work in it productively or whether a specific part needs replacing.
These are the tools we use most, not the only ones. Vue, Svelte and other options come up, and we will say when one is a better fit than our defaults. What we avoid is a rewrite for its own sake.
Questions we ask first
What actually narrows the options
- Who maintains the product after launch — your in-house team, an external partner, or us on an ongoing basis.
- What the product has to integrate with — payment providers, CRMs, internal APIs, or an existing mobile app.
- How often the product changes — a brochure site and a real-time dashboard point to different answers.
- Where it will be hosted, and whether your team already has a deployment process worth keeping.
Questions we get about working with a stack
Can you work with a stack we already use?
Usually. We will review the codebase and say whether we can work in it productively or whether a specific part needs replacing.
Do you only build with the tools listed here?
No. These are the ones we use most. Vue, Svelte and other options come up, and we will say when one is a better fit than our defaults.
Is WordPress suitable for anything beyond blogs?
Yes. With custom post types and fields it handles corporate sites, directories and content platforms. It is less suited to complex application logic, where a custom build is cleaner.
