What We've Built

Products we build and run ourselves, and software we built for clients.

Arc Labs · Education →

Arc Academy Terminal

An open-source terminal app for learning the Linux command line by using it, on a simulated system where mistakes cost nothing.

Open source, GPL-2.0. Version 1.0.

A personal safety app for iPhone: check-ins with a trusted circle and one-tap alerts.

In public beta on TestFlight. iOS 17 or later.

Arc Labs · Applied AI →

Nitekeep

An AI front desk for creative studios that rent out their space. It drafts replies in the host’s own voice and holds anything that needs judgment.

Client Work →

Training platform for a youth sports academy

Programs, camps, booking and a parent portal for a private youth sports training business in California, in English and Spanish.

Live. Designed and built by Arc Labs, which licenses the platform to the business.

Principles

Privacy by Design

Data lives where its owner controls it. Each customer’s data is theirs alone.

Build for the Person with the Most at Stake

A beginner at a command line, someone who needs help fast, a host whose bookings depend on a reply.

Ship Real Things

Working software over slideware.

Work Honestly

Say what we know, and what we don’t.

How We Work

Research First

Map what exists before building anything new

Build & Learn

Running software early, improved by using it

Teach What We Know

Write up what we learn and publish it

Security Minded

Think about misuse from the first line of code

Hand Over Everything

Clients receive the source and the documentation
