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.
“This is a great extension. If it could remember the custom sidebar width, that would be much better. Each time I open it, I need to drag the sidebar wider, which is not convenient.”

“Temos de fornecer 1000 estrelas!”
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.
