After 5 months and 1,500+ hours of development, I'm finally launching Zephium. A fast, private, fully featured browser and work environment, reimagined for you and your agents. Fully OSS, built in Rust. 40 MB. Not a Chromium fork. Native adblocking, Chrome extension support, deeply integrated productivity tools, a custom agentic browsing engine, and a lot more. It's not just another wrapper built in a few days. And... Work mode: a shared environment where you and AI agents can browse, research, build, and get real work done together. Live browser sessions, parallel sub-agents, tools, files, components, and interactive results, all in one canvas. AI is optional (disable in one click). No telemetry. BYOK support and local models. zephium.app github.com/zephium-browser/Z… youtu.be/QbSarcWspvw

Btw, I even used GPT-6 Luna for this, not Sol or Astra

Same task: "System design for modern AI SaaS" 1) Zephium's Work Mode (canvas-based workspace and browsing environment) 2) Claude's Whiteboard P.S. This is the old UI in the screenshot. I've improved it since then, and there are still a lot of things I want to improve. This is just the beginning and most of my time (around 1 month) went into building the custom agentic browsing engine in Rust, but it's still pretty cool

Yeah, Zephium looks nice not only on macOS, I guess

Zephium just hit 1,000 stars on GitHub! Pretty cool to see how much the project has grown since launch. But still 9 times smaller than Terax (btw, will release v0.10 there soon), so we're going :) Thanks to everyone who's been following, contributing, and building with me

GitHub has changed the colors of the activity dashboard for some reason, so I asked Zephium's AI to bring them back :)

When I made a video about Terax, it hit 100K+ views in 1 month. A lot of people asked how the terminal was built A month ago I made a technical follow-up where I described how terminals work by building a minimal AI terminal using Rust + Tauri + xterm.js youtu.be/X1N5d-5AHeA

For the past two months, I’ve been quietly working on my own browser Zephium. Terax in the morning (which already has 9K stars), Zephium in the evening :) It’s not a Chromium/Firefox fork. The browser is written in Rust on top of each platform’s native WebView. FOSS. 0 telemetry
