Software for the people
mainstream tech left behind.
为主流科技遗忘的人群,打造软件。

The cost of building great software has collapsed. We build products from the ground up — for the communities, languages, and subcultures never worth solving at scale — around problems we've lived ourselves.

Why Codeswitch

Three ideas run through everything we build.

Not a house style bolted on after the fact — the operating premise underneath every product in the catalog.

壹 / 01

Language first, not localized last

Every product starts multilingual — the user's language is the ground floor, not a translation layer bolted on after the English ships.

贰 / 02

Built from lived use cases

Each product began as a real problem in a real family or community we're part of — discovered because we lived it, not sized in a spreadsheet.

叁 / 03

Small studio, real systems

A disciplined internal system lets a two-person team ship precise, maintained software. See How We Build below.

What we've built

Products, not slideware.

Live software serving real communities — each one a proof point for the studio.

Hanzi Rain 汉字雨

Characters rain down; you clear them by recall before they land. Miss too many and the screen fills up — just like real review, except you'll actually come back tomorrow. The arcade cure for flashcard burnout.

Arcade · in tune-up

TypeSnake

Steer the snake by typing — every turn is a word, every word is speed. A retro terminal-green arcade for people who think 120 WPM is a personality trait. Same arcade obsession that built Hanzi Rain.

How we build

A small studio system, run like an assembly line for precision.

Every product above runs through the same internal pipeline — one role finds the signal, one role owns the truth, one role ships it.

The Scout

Gathers and structures outside signal — market data, competitor pricing, raw bilingual language pairs from the open web. Surfaces the highest-signal gaps for the Archivist. Never authors final IP itself.

Your website, set up and looked after — without becoming your hobby.

For tutors, coaches, small practices, and families: we build your site, wire the boring-but-critical plumbing (domain, DNS, email, backups), and then keep it alive so you never think about it again.

① Setup

Launch, done right

A clean site that says what you do — plus domain, hosting, HTTPS, and an email address at your own name. Yours outright: no platform lock-in, no rented land.

② Care

Ongoing admin

Updates, content changes, renewals, backups, and monitoring — handled on a simple monthly care plan. You send a note; it's live the next day.

③ Grow

When you're ready

Booking forms, bilingual pages, client-lead notifications, a newsletter — added as your practice grows, never sold before you need them.

How it works: one conversation → a working draft within days → you approve → live, with care ongoing. Book a conversation →

Hire the studio

Every product here started as a problem we had to solve ourselves.

If you've got a linguistic or cultural edge case mainstream software keeps getting wrong, that's exactly our lane. We build in your users' language first — and we can build one for you.
