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.
“最高の機能です。”
“Cumpre MARAVILHOSAMENTE aquilo que promete. Na minha opinião, é a melhor Sidebar que tem. ”
“Very useful”
“非常棒，可惜gmail拒绝 iframe 连接，其他的都很好”
“rất tiện lợi”
“很好用，非常感恩开发者，有几个建议希望后期能改进： 1.用快捷键关闭侧边栏然后再打开，原本打开的页面都消失了，都重置为默认了，能不能设置为保留原样？ 2.我想让常用的几个网页始终固定在最上那一列，希望后期能有这个功能； 3.能否自定义每次打开侧边栏的时候就直接进入了某个网页，比如ChatGPT网页，而不是像现在这样还需要点一下ChatGPT的logo 4.能否添加设置页面的字体大小”
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.
