Tech Stack

The stack we build real products with.

One Peak ships web and mobile products end to end. These are the core technologies behind our work — chosen because they let a compact team move fast without trading away architecture or reliability.

Frontend & web

Production web apps with SEO performance and a clean component system.

Next.js — SSR, SEO, and full-stack in one framework
React & TypeScript — component-based, type-safe UIs
Tailwind CSS — consistent, utility-first styling

Mobile

Cross-platform apps that feel native, from one codebase.

React Native — iOS and Android from shared code
Flutter — pixel-perfect, multi-platform builds
Native iOS where it matters

Backend & AI

Backends that go live in days and AI features users actually use.

Supabase — Postgres, auth, realtime, storage
Node.js & REST APIs — integrations done right
OpenAI & Claude — practical, scoped AI features

Practical answers

Questions founders ask before moving forward.

Do you only work with these technologies?

These are our defaults because we know their edge cases and can move fast on them. We pick the tool to fit the product, not the other way around.

Can you join an existing codebase?

Yes. We regularly extend existing products — adding features, fixing architecture, or integrating new services — as well as building from scratch.
