Software & AI Engineer | Building @zephium_browser and (9.5K+ ⭐)

[Crynta @CryntaDev]

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.

@andrwmai No, on macOS it will natively work with Apple Passwords. And also, I'm planning to make our own native and local password manager, which will be the most integrated and resource-efficient option for Zephium

[Crynta @CryntaDev]

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

[Crynta @CryntaDev]

@andrwmai I've applied for it, so I guess Apple should approve the certificate sometime this week. For now, I've improved the UX to make that part smoother until full support is available

@jasonngsx Nope, I remember that :) I just wanted to make that part more polished rather than simply copying Arc. I'm working on it right now and plan to release the new version in a few days

[Crynta @CryntaDev]

Just released the new Zephium v1.0.5

- Native YouTube ad blocking
- Improved extension support
- Bangs & shortcuts
- A bunch of UI/UX improvements
- Performance & RAM optimizations
And a lot more

Next up: a new Terax release

[Crynta @CryntaDev]

@cherriessire I'll publish them today

[Crynta @CryntaDev]

@gabrulel It's WKWebView (WebKit) on macOS and WebView2 (Edge's engine) on Windows

[Crynta @CryntaDev]

@hkay_okay Thanks for the great feedback :)

[Crynta @CryntaDev]

@anirudiculous Yes, WebKitGTK, it has been improved a lot in the newest versions, so we'll use that

[Crynta @CryntaDev]

@dynamikoff Nothing here is from the Zen browser

[Crynta @CryntaDev]

@chunyoutube I guess it's a problem only in compacted mode, because the native handler fights against the UI's one. Thanks for reporting this, I'll fix this right now

[Crynta @CryntaDev]

@Lafish49 Thanks for the feedback, I'll add and improve all the things you said in the next release

[Crynta @CryntaDev]

Zephium, as it is today:
An OSS, fully featured browser written in Rust. Not a Chromium fork. 40 MB. Native adblocking, extensions support, productivity built-in.
Work mode: canvas-based environment for you and your agents with everything you need to get the work done.

@Dickson888888 Not yet, but I'll add that in the next releases. I think it will be the same time with the linux version, because I need to write our own extension runtime for both WebKitGTK and WKWebView (Intel macs)

@ArshaanImam Yes, I'll release the iOS and Android versions right after Linux

[Crynta @CryntaDev]

@SamSanak_ You can just compact/hide it :)

[Crynta @CryntaDev]

@_mr_agu_ Ah, thank you for reporting this, I'll fix that right now

[Crynta @CryntaDev]

@ExpertPlus_ Working on that right now :)
