Vangr Labs

Building weird, useful and occasionally production-ready software.

We're a small engineering lab that enjoys building things.

Mostly mobile. Mostly Kotlin. Occasionally hardware. Frequently over-engineered. Usually worth it.

Our work spans native Android, iOS, Kotlin Multiplatform, backend services, developer tooling and embedded devices.

Some projects power festivals. Some automate our homes. Some make engineers more productive. Some exist simply because we wanted to know if something was possible.


What we build

📱 Mobile

Native Android, iOS and Kotlin Multiplatform applications built with modern architecture and Jetpack Compose.

☁️ Backend

APIs, authentication, event platforms, integrations and cloud infrastructure.

🎸 Festival Tech

Technology for running real-world events.

Ticketing, schedules, food ordering, notifications, QR hunts, volunteer tools and operational software.

🏠 Home Automation

Home Assistant, ESPHome, NIBE integrations, IoT and energy management.

🛠 Engineering Tools

Developer tooling, CI/CD, testing infrastructure, architecture experiments and internal productivity tools.

🤖 AI

Automation, LLM integrations, image generation and AI-assisted software development.

Philosophy

We like shipping.

We like learning.

We like solving our own problems.

We believe software should be pleasant to build, pleasant to use and pleasant to maintain.

Sometimes we open source things.

Sometimes we don't.

Either way, we try to build them well.
