What we do

Product teams, without the overhead

One small senior team across the whole stack — design, mobile, backend and the platform it all runs on.

React Native apps

Mobile

Cross-platform iOS & Android from one codebase — native feel, fast iteration, App Store & Play releases.

Node.js & AdonisJS APIs

Backend

Typed, well-tested backends — auth, data, background jobs and real-time, built to last.

Servers & hosting

Platform

We run our own PaaS — build-on-push, automatic TLS, zero-downtime rollouts, backups and monitoring.

Product & delivery

End-to-end

From first sketch to production and on-call — we build it, ship it, and keep it running.

Case study

We built Hüff

A breathwork & meditation app — designed, built and run by Eightyfour. React Native on the front, an AdonisJS API behind it, hosted on our own platform.

AdonisJS + Postgres API and CMS
Runs on our PaaS with push-to-deploy

“Small team. Full stack. We build it, then we run it.”
Eightyfour is a software development studio — product, engineering and platform under one roof.
