Existence
You’ll never be here again.
We build e_core, the Flutter framework behind our six live apps, and we build apps for teams who’d rather ship in weeks than months.

The framework
The boilerplate is already solved.
One command scaffolds a complete Flutter app, production-ready and fully customisable. Your team starts at the part that makes your product unique.
$ e_core create my_app
Creating new e_core app…
✓ Auth system configured
✓ Settings screens generated
✓ Theme system initialized
✓ Routes configured
✓ Providers set up
Done in 28.4s. Run cd my_app && flutter run

Done in 28.4s. Run cd my_app && flutter run
Complete auth, settings and profile screens, theme dialogs, guarded routing, provider setup, from one command.
OUT OF THE BOX
Authentication
Email, phone, and social sign-in, Google, Apple, Microsoft, with complete verification flows.
ANY BACKEND
Backend-agnostic
Switch between Firebase, REST, Supabase, or GraphQL without rewriting app logic.
15 PACKAGES · 7 LAYERS
Modular architecture
Independent packages with clean separation, use only what you need; tree-shaking removes the rest.
12+ LANGUAGES
Internationalisation
12+ languages out of the box, with RTL support for Arabic, Hebrew, and Farsi.
TYPE-SAFE
Smart routing & state
Auto-configured routes with role and premium guards; centralised, testable Riverpod state.
90%+ COVERAGE TARGET
Built for testing
Easy-to-mock providers; unit, widget, and integration tests with Firebase emulator support.
Time savings
Weeks of boilerplate, gone.
Focus your engineers on features, not scaffolding. Time to MVP drops from 4–6 weeks to 1–2, before you count the maintenance you no longer own.
AI writes code faster. Someone still has to integrate, harden, and maintain it. That is the part we sell.

Accelerated delivery
We deliver your app on e_core, at framework speed.
For teams that want the outcome, not the codebase: the people who built the framework, and ship 6+ production apps on it, build yours. Production-grade from day one, because the core already is. Handover, or ongoing under SLA.
See how the framework works in the docs, then bring us in when the stakes rise.
Scope a buildThe proving ground
We run our own apps on the core we sell.
Six-plus products live on Android, iOS, and web, through real App Store review, in front of real users, monetising. Every release hardens the framework before it reaches your team. And each one exists for a reason: technology in service of a fuller, more present life.
Confessions
Spill The Tea
Every one of them is why the framework holds. You’ll never be here again.
From the team
Notes from production.
Localisation
EngineeringSpeaking your language: one localisation layer for every Existence appEvery word our apps showed was once hardcoded in English, tied to the screen that displayed it. We pulled all of it into a single shared layer, so reaching a new audience in their own language is finally a content change, not a rebuild.July 2026
Privacy by construction
EngineeringThe prompts that never leave the building: local LLMs for sensitive IPSome of our AI work touches unreleased code, product designs, and customer data we're duty-bound to protect. Here's why we moved that slice onto models that run entirely on our own hardware, and how we decide, prompt by prompt.July 2026
Notifications
EngineeringShipping e_core_notifications: one notifications layer for every Existence appLocal, scheduled, and push notifications, plus an inbox, deep links, and topic subscriptions, now live behind a single tested package. Here is what we built, and why we stopped writing notification code by hand.July 2026
