Library
Technical library,
kept secondary on purpose.
This section keeps the comparisons, checklists, and build notes public. It is useful, but it is not the main job of the site. If you are here because you need a website, redesign, or product execution in Costa Rica, start with the commercial lanes below.
Resource lists
Curated references by stack and tooling category.
Useful if you are comparing implementation options. Not the first place to start if you are trying to hire me for a website or product build.

Best Libraries for Astro in 2026
Astro clicked for me the moment I realized content sites don't need a JavaScript framework fighting the browser. I've rebuilt two production sites with Astro and the performance improvements were dramatic. These libraries represent what the Astro ecosystem does best — fast content delivery with islands of interactivity where you actually need them.

Best Libraries for Next.js in 2026
Next.js has matured into the default framework for production React apps, but choosing the right companion libraries can make or break your developer experience. We use many of these daily at GEXP Software and have tested them across dozens of production deployments. Here are the libraries that consistently deliver results in 2026.

Best Libraries for React in 2026
React's ecosystem is enormous, which makes choosing the right libraries overwhelming. After years of building React applications for clients at GEXP Software, we've narrowed down the libraries that consistently prove their worth. These are the ones we reach for first in every new project.

Best Libraries for Supabase in 2026
Supabase gives you Postgres, auth, storage, and real-time out of the box — but the real power comes from the ecosystem built around it. I've used Supabase in three production apps and these libraries turned it from a nice backend into a full platform. Here's what actually works beyond the quickstart tutorial.

Best Libraries for Svelte in 2026
Svelte's ecosystem is smaller than React's but the quality per library is remarkably high. I've used Svelte for several side projects and a production app — the developer experience is addictive. These libraries earned their spot by being genuinely useful, not just Svelte ports of React patterns.

Best Libraries for Tailwind CSS in 2026
Tailwind CSS v4 has solidified its position as the styling framework of choice for modern web development. The ecosystem around it has grown to include everything from component libraries to animation utilities. At GEXP Software, Tailwind is the foundation of every project we build — here are the libraries that make it even better.

Best Libraries for Three.js in 2026
Three.js remains the backbone of 3D on the web, but its ecosystem of companion libraries is what makes complex projects feasible. At GEXP Software, we build immersive 3D experiences with Three.js for client projects — from morphing wireframe heroes to interactive product configurators. These libraries make the difference between a weekend prototype and a production-grade experience.

Best Libraries for TypeScript in 2026
TypeScript has become the default for serious JavaScript development, and the best libraries are now designed TypeScript-first — not with types bolted on as an afterthought. At GEXP Software, every project starts with TypeScript and we select libraries that leverage the type system fully. These are the packages that make TypeScript development a joy.

Best Tools for AI Development in 2026
AI has moved from experimental to essential in software development — both as a tool developers use and as a capability they build into products. The landscape of AI development tools is evolving weekly, making it hard to know what's battle-tested versus hype. At GEXP Software, we integrate AI capabilities into client applications and use AI tools in our own workflow. These are the tools that deliver real value.

Best Tools for Bun in 2026
Bun went from hype to genuinely useful fast. I've moved several scripts, APIs, and even a few production services to Bun — the speed gains are real but the ecosystem is still catching up. These tools represent what actually works with Bun today, not what's theoretically compatible.

Best Tools for Frontend Testing in 2026
Frontend testing has gone from painful to powerful. I've shipped apps with zero test coverage and apps with comprehensive suites — the difference in confidence at deploy time is night and day. These are the tools I've actually used across React, Next.js, and Svelte projects, not a theoretical list from a blog post.

Best Tools for Next.js in 2026
Building a Next.js app is just the start — the tools you pair with it determine how fast you ship, how reliably it runs, and how well you understand your users. We've tested these across real client projects and internal products at GEXP Software. These are the tools that earn their place in our stack.

Best Tools for Node.js in 2026
Node.js continues to power a massive share of backend services, APIs, and tooling. The ecosystem has shifted toward TypeScript-first tools, Rust-powered runtimes, and edge-compatible architectures. At GEXP Software, we build and maintain Node.js services for clients across industries — these are the tools that keep our stack reliable and productive.

Best Tools for React in 2026
The React ecosystem's tooling has matured dramatically — from Rust-powered bundlers to AI-assisted development. Picking the right tools for your workflow can save hours every week. Here are the tools we use and recommend at GEXP Software for building React applications efficiently.

Best Tools for shadcn/ui in 2026
shadcn/ui changed how I think about component libraries — you own the code, customize freely, and there's no abstraction to fight. But the ecosystem around it is what makes it truly powerful. These tools extend shadcn/ui with themes, registries, form builders, and animations that would take weeks to build yourself.

Best Tools for Supabase in 2026
Supabase has become the go-to open-source Firebase alternative, offering Postgres, authentication, real-time subscriptions, storage, and edge functions in one platform. The ecosystem of companion tools has grown rapidly to fill gaps and extend capabilities. Here are the tools we use at GEXP Software to build production Supabase applications efficiently.

Best Tools for Three.js in 2026
Three.js is powerful but the raw API is verbose and debugging 3D is hard. The right tools make the difference between fighting WebGL and actually shipping creative work. I've used these across interactive portfolio pieces, product configurators, and experimental 3D projects — they're what keep Three.js productive.

Best Tools for TypeScript in 2026
TypeScript's ecosystem has matured well beyond just tsc. I've spent years wrestling with type errors, migrating JavaScript codebases, and fine-tuning developer workflows — these are the tools that actually made a difference in my projects. From blazing-fast linters to visual type explorers, this is what I reach for daily.
Commercial path
If you need execution, leave the library and go to the right lane.
The technical library stays public because it is useful. The commercial path for this site is still simple: choose the Costa Rica lane that matches your business, then request a quote with proper context.
