Why fastr

Built for the way
you actually browse.

Not another extension. Not another app to download. fastr is a lightweight chat layer that lives on top of the web.

Any URL, Any Website
Shopping pages, news articles, documentation, GitHub repos — if it has a URL, it has a chat room waiting.
Privacy by Design
We don't track your browsing. We don't sell your data. We don't even store chat history unless you opt in.
Smart Moderation
AI-powered content filtering, user blocking, and community reporting. Safe conversations are the default, not the exception.
Desktop & Mobile
Start a conversation on your laptop, continue on your phone. Same URL, same room, perfectly synced across devices.

FAQ

Questions?
We've got answers.

Do I need to install a browser extension?
No. fastr works entirely through the web — just sign up and visit any page through fastr, or use our bookmarklet for one-click access from any site. No downloads, no extensions.
How does the bookmarklet work?
Drag the "Chat on fastr" button to your browser's bookmarks bar. When you're on any webpage, click it — fastr will instantly open a chat room for that URL. It works in Chrome, Firefox, Edge, Safari, and Brave.
What websites does fastr work on?
Every website with a URL. Shopping sites, news articles, YouTube videos, Stack Overflow pages, GitHub repos, documentation — if it has a URL, you can chat about it on fastr.
Why do I need to sign up if it's "no install"?
Signing up (10 seconds via email) lets us save your preferences, chat history, and username across sessions. Without an account, you'd lose everything when you close the tab. There's nothing to install — it all runs in your browser.

The web is better
when you can talk about it.

Join people who've turned their browser into a conversation.
