WEIN Technology is a Hong Kong studio that designs, builds and runs its own products — an AI API gateway, open-source developer and privacy tools, and an original browser game. The same team builds AI software, games and mini programs for clients, from the first sketch to long after launch.
What’s in a name
Two characters. One way of working.
Particles · sparks · details. A pixel, a millisecond, a line of code. Good products are thousands of small, deliberate decisions — we take every one of them seriously.
Gravity · engine · guide. The force that draws scattered pieces together and moves them in one direction. That’s the role we play on every project.
An AI gateway, an original game and open-source tools — designed, built and maintained in-house. What we recommend to clients, we practise on our own products first.
See all workOur name comes from 微引 — “a tiny pull”. Scattered particles, drawn together by a steady force, eventually take shape. Software is made the same way: hundreds of small, deliberate decisions pulled in one direction. The best way to prove that works is to do it for ourselves first.
So we build and run our own products. SHUAI API is the AI API gateway we develop and operate — one OpenAI-compatible interface to popular models. Hlool PDF, HloolMail and Shuiyin are open-source developer and privacy tools, with HloolMail past a hundred stars on GitHub. GREYFALL is an original browser game we made from scratch. We shipped every one of them ourselves, and we still maintain them all.
The same team builds AI software, games and mini programs for clients, working in Cantonese, Mandarin and English. What we value is simple to say and hard to do: honest estimates, regular demos you can click through, and code and documentation you fully own. We don’t judge a project by launch day. We judge it by whether people still use it a year later — the same bar we hold our own products to.
Most ideas don’t fail for lack of ambition — they drift. Scope blurs, budgets scatter, momentum fades. We supply the pull: clear priorities, careful craft and a steady delivery rhythm, until a spark becomes a product people rely on.
The craft of a world-class product team should be within reach of any company with a good idea — a small trading firm, an indie developer, a two-person game studio. We’re building that studio in Hong Kong: bilingual by default, connected to the mainland and the world, and made to last.
Simple to say, hard to do. They shape how we estimate, communicate and deliver — and what happens after launch.
We care as much about a 200-millisecond transition as about an edge case in the payment flow. Every release passes design review, code review and testing on real devices before it reaches your users.
Regular demos, a shared task board and a budget tracker you can check any day. If something is at risk, you hear it from us first — along with a plan to fix it.
We run our own products for the long haul, so we design for year two, not just launch day: documented architecture, handover-ready code and real support after go-live. We’d rather earn your next project than lock you into this one.
We prototype new models, engines and platforms before we recommend them. Running SHUAI API lets us compare models first-hand, so we can tell you with evidence what’s ready for production and what’s still hype.
Designers and engineers work side by side from day one, so concept, interface, code and life after launch are solved at the same table.
LLM applications, agents and retrieval systems built for production — with evaluation, guardrails and cost controls — connected to many models through the SHUAI API gateway we operate, or to privately hosted ones.
From core-loop prototype to live game: game feel, level pacing, progression systems and performance. Our original browser game GREYFALL comes from this team, and we take on web, Unity and Cocos Creator projects.
Fast, accessible web apps and mini programs for WeChat, Alipay and Douyin. Our open-source tools Hlool PDF and Shuiyin keep files in the browser and process them locally.
APIs, data pipelines and infrastructure built with Go, PostgreSQL, Docker and S3-compatible storage — the stack behind our own products — deployed on AWS, Alibaba Cloud, Tencent Cloud or Cloudflare, sized for your real traffic.
Research-led UX, interface and motion design, delivered as living design systems that engineers build from directly.
One accountable lead who owns scope, priorities and timeline, runs the regular demos and keeps every stakeholder aligned — in Cantonese, Mandarin or English.
We work in Cantonese, Mandarin and English with clients in Hong Kong, across the Greater Bay Area and overseas — so nothing gets lost between languages, time zones or cultures.
Headquarters
Hong Kong
Strategy, design and engineering under one roof. We meet Hong Kong clients face to face and work with teams on the mainland and overseas from here.
Remote collaboration
Greater Bay Area
Remote-first collaboration with teams in Shenzhen, Guangzhou and across the bay, with on-site workshops whenever a project needs them.
Open source
The source is public — anyone can self-host, audit and improve it.
From the first sketch to life after launch — one team, all the way.
