Noriter Lab — a studio that has run a community since 2009

01 · Our story

It all started
with Noriter.

Noriter means “playground” in Korean, a word every Korean knows, and noriter.com has been ours since 2009. Launched that year as a mobile-phone community, Noriter gathered 300,000 posts and 850,000 comments over seventeen years. To move all of it while keeping every record and URL intact, we built the engine ourselves.

2009
Noriter opens
Noriter (놀이터) is the everyday Korean word for “playground”, and we have held noriter.com, the plain-word domain, since day one. It began as a community for sharing phone and carrier-plan know-how. 230,000 posts in 2010 and 2011 alone.

2009 – 2026
Seventeen years of records
300K posts, 850K comments, 39K attachments. Just before an aging server went down, we recovered the data from the last surviving install.

02 · Gbun ecosystem

One engine.
Connected products.

We don't rebuild the same features for every site. GbunBoard handles community, members, content and admin; commerce, video, stories and developer tools plug in as independent products.

Core engine

GbunBoard

One engine for communities, boards, publishing, members and permissions, and admin. It runs on the global edge with no servers to manage, and grows through plugins.

04 · How we build

Built by a team of AI agents.
Owned to the end.

We built, and use every day, our own AI-agent development system that separates design, build and review. Code that has been written and a product that actually works are judged separately.

01 · DESIGN

Close the design first

Lock structure, contracts and data shapes, and draw every screen as a mockup first.

02 · BUILD

Agents build in parallel

Work is split so it never overlaps, and several agents build at once.

03 · VERIFY

Check by eye and by test

Compare mockup and real screen side by side, then use it end to end in a real browser.

04 · OPERATE

Learn from operations

Ship to real sites and feed what visitors teach us back into the engine.

05 · Multilingual

Multilingual

Per-language URLs, managed translation sources, and layouts that hold up when sentence length changes between languages, all handled at the engine level.
