I built the first-ever protocol for browser-website collaboration. Let me explain:
The way we browse the web hasn’t really changed in over a decade.
On one side, we have browsers. They have historically been made to show us and letting us interact with pages, not to understand them. Up until now,, they've been pretty passive.
On the other side, we have websites. They’ve actually evolved a lot: from static HTML in the 90s, to interactive sites in the 2000s, to full web apps today.
But lately things have changed massively: Now we have browsers that can do stuff on the websites on our behalf. Atlas, Comet, Dia, Cleo. They can plan, reason, and execute.
And suddenly, browser-website communication matters more than ever. If browsers can act, they need to truly understand the sites they visit.
❌ The problem? Every current attempt at letting browsers take action on a website, is brittle. It relies on AI guessing what a site means or can do. There’s still no native way for browsers to talk to websites. There’s no bridge, no way for them to cooperate.
Until now.
🌅 Introducing ASTRAL
ASTRAL is a new standard: a protocol that lets websites natively talk to browsers. A bridge for browsers and websites to finally work together.
It’s a lightweight capability layer that lets websites describe what they can do, and browsers understand, reason, and act inside the site, with their permission.
When you open a site, the browser instantly knows its purpose and capabilities. It adds those to its toolkit. And when it’s time to act, it does so within the site’s rules.
The site defines what’s possible.
The browser decides when and how to use it.
We’re building a new era of the internet. One that feels natural, where browsers and websites speak the same language.
With the ASTRAL protocol, the browser can finally understands the sites it visits, can adapt its ui to you, can collaborate not just with one website, but with multiple.
This unlocks a whole new layer of user-web interaction. It’s a massive step towards an internet that’s semantic, dynamic, personal, and human.
This is my biggest launch up to date, and I'm excited to see where this goes.
➡️ I'm inviting early builders to try this with me. If you're shipping web apps, AI-native products, or just love breaking the web open in new ways, reach out.
