Our Tech Stack

At WithSeismic, we’ve carefully selected a modern, performance-focused stack that allows us to ship interactive tools in 2-4 week sprints. Every technology choice is optimized for rapid development and stellar user experience.

​
Core Technologies

TypeScript

Type-safe JavaScript for building robust, maintainable applications with fewer runtime errors.

React

Component-based UI library for building interactive user interfaces with predictable data flow.

Next.js

Full-stack React framework with built-in routing, SSR/SSG, and optimized performance out of the box.

Vite

Lightning-fast build tool and dev server for modern web projects with hot module replacement.

​
Backend & Infrastructure

Node.js

JavaScript runtime for building scalable server-side applications with a massive ecosystem.

Hono

Ultra-fast, lightweight web framework for building APIs with excellent TypeScript support.

Railway

Modern infrastructure platform for deploying and scaling applications with zero DevOps overhead.

​
UI & State Management

Tailwind CSS

Utility-first CSS framework for rapidly building custom user interfaces without leaving your HTML.

Motion

Production-ready animation library (formerly Framer Motion) for creating fluid, gesture-based interactions.

Zustand

Lightweight state management solution that’s simple, fast, and scales from small to complex applications.

TanStack Query

Powerful data synchronization library (formerly React Query) for fetching, caching, and updating server state.

​
Communication & Project Management

We maintain clear, consistent communication channels with our clients throughout every sprint:

Slack

Real-time messaging for daily updates, quick questions, and seamless collaboration.

Google Meet

Video conferencing for discovery workshops, sprint reviews, and strategic discussions.

Linear

Modern issue tracking for managing sprint tasks, tracking progress, and maintaining transparency.

Why This Stack?

Every tool in our stack is chosen for a specific reason:
  • Speed: Vite’s instant HMR and Next.js optimizations mean we iterate faster
  • Type Safety: TypeScript catches errors before runtime, reducing bugs in production
  • Developer Experience: Modern tooling means we spend time building features, not fighting config
  • Performance: Every choice prioritizes sub-second load times and smooth interactions
  • Scalability: From MVP to millions of users, this stack grows with your success
This is the exact stack we use to build interactive tools that convert. No theoretical choices—these are battle-tested technologies we ship with every day.
