Big software.
Tiny tab.
Tools that respect your time.
We build software the way we wish more software was built — fast, private, and out of your way.
Faster than installing anything
Open the page, use the tool, close the tab. No downloads, no setup wizards, no system permissions to approve.
Private by design
Your documents and data stay on your device. WebAssembly lets us run real software without sending anything to a server.
No accounts required
Skip the signup forms. Skip the email verification. Skip the upsell popups. Just open and start using.
Built to last, updated weekly
These aren’t side projects. We ship updates almost every week and stand behind every tool with active support.
Browser-native tools. Free to start.
Browser extensions, full WebAssembly apps, web tools. Every one runs on your machine — and we’re still building more.
Anything Copilot
Chat with AI, translate pages, multitask between tabs — all without leaving what you’re doing.
Blitz Capture
Capture an entire scrolling page — even 10+ screens long — pixel-perfect, in less than a second.
ZIZIYI Office
A real office suite running on your machine. No Microsoft account, no upload, no install.
Online MCP Inspector
A browser-based inspector for MCP servers. Debug, test, and explore MCP protocols without any install.
People who use these stick around.
“Me pase de opera Gx a Brave y me hacia falta la barra lateral con varias aplicaciones, esta extensión lo soluciono por completo y puedo tener cualquier pagina practicamente en la barra lateral.”
“Хорошая удобная панель”
“Super pasé de Edge a Comet, pero la barra lateral de Edge me hacía falta para trabajar con varias I.A al mismo tiempo y hacer revisiones y navegaciones rápidas, esta app lo solucionó e incluso mejoro!!”
“ajuda muito!”
“Tìm mãi mới thấy tính năng này. cảm ơn đội ngũ phát triển. Bên edge có tính năng này từ lâu, mà chrome không có. split màn hình như này tiết kiệm không gian hiển thị, linh hoạt khi làm việc với nhiều tab cùng lúc. Dần dần phát triển được như split screen của edge thì quá tuyệt vời. ^^”
“ai 탭창이 12개인데..틈세 니즈를 반영한듯. 화면분할이 필요해서 검색하다가 이걸 발견했는데.. 화면분할보다 요긴함. 욕심은...정보 수집 툴과 메모 정리기능이 있으면 좋을듯~”
A small team that loves browsers.
ZIZIYI started as a side project — one extension, one stubborn belief that browser-native software was an underrated path. Three years later it’s four products used by twenty thousand people, and the same conviction.
We’re independent, self-funded, and small on purpose. No trackers, no ads, no upsells. We charge a fair price for the Pro features so we can keep building things we’re proud of, full-time.
