[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.

@Princy_Stolas I'm constantly working on extension improvements to have more stable and proper Chrome extension support without Chrome :)

[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]

@_copypaster_ It will be available very soon. You can join the waitlist on the website

[Crynta @CryntaDev]

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

[Crynta @CryntaDev]

@KDB_17MCI Sure, there is more to come, I'm improving it every day

[Crynta @CryntaDev]

@marbismalla Right after the Linux version

[Crynta @CryntaDev]

@theh8h Yes, starting from v0.9.0 Terax now uses libghostty + WebGPU instead of xtermjs

[Crynta @CryntaDev]

@theh8h I'm not that good :) I've just been coding literally every single day for the past 5-6 years, + the experience of building fintech desktop apps, a metadata editor for photogs, Terax (my AI ADE with 9.5K+ stars), etc.
I just genuinely love what I do

[Crynta @CryntaDev]

@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]

@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

[Crynta @CryntaDev]

[Crynta @CryntaDev]

@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]

@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.
1K+ ⭐ on Github already and 65K+ views on YouTube

[Crynta @CryntaDev]

@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)
