PeerSky is a gateway to the peer-to-peer web, not just a browser. It turns your computer or phone into a node (a server for the network), so pages, files, chats and notes can come from the people who have them rather than from one company’s server. The everyday web works as usual, and alongside it PeerSky carries a full ecosystem of apps built on the same idea: chat, shared notes, file sharing, a music player and, on desktop, a local AI.

Your device talks to other people’s devices directly instead of going through a company’s computers. With no server keeping everyone’s data, there is nothing to hack, leak, sell or switch off. The one catch: the device that has what you want, a page, a file or a message, needs to be online for it to reach you.

Between devices on the same Wi-Fi, yes. They find each other and talk directly, so there is nothing out on the internet to reach. Any local network will do, even a phone’s hotspot with no data behind it: during an internet shutdown, in a power cut, at a festival, or wherever the internet is down or blocked. Some public Wi-Fi keeps devices apart, and there a hotspot works instead. Regular websites still need the internet.

Yes. Regular http and https websites work as in any other browser: search, logins, videos, downloads, bookmarks and tabs. The peer-to-peer web sits right alongside them.

It is free and open source, with no ads and no subscriptions. There is no account to make: open it and start browsing.

Yes, on every site. The desktop app comes with uBlock Origin, and the phone apps block ads and trackers inside the browser engine from the first launch.

Anyone who wants the web on their own terms:

• Everyday users who want to browse without ads or tracking, and use the peer-to-peer web.
• Journalists and activists who need to share files and talk with no company in the middle.
• Underrepresented communities building their own spaces online, which no platform can take down.
• People living through internet shutdowns, or with slow or censored connections, who still need to reach each other on a local network.
• Friends, families and teams who chat and write together.
• Developers building apps for the peer-to-peer web.

Anyone your device connects to directly: the people you share with, and the devices on the network that help peers find each other. That is how peer to peer works, and most apps are the same: even Signal’s servers see your IP address, and so does every website you visit, in any browser. To keep it from all of them, turn on a VPN. People then see the VPN’s address, not yours.

Nothing. There are no accounts, no analytics and no tracking, and your history, tabs and files stay on your device. The only numbers we see are download counts, from GitHub’s releases and from the App Store and Google Play. We don’t track active users, and we don’t even ask for your email for a newsletter: follow us on Mastodon or Bluesky instead. The privacy statements for desktop and mobile say exactly what leaves your device.

Yes. Link Device brings your private drives, notes, tabs and bookmarks from PeerSky Desktop to your phone, and moves everything from one phone to another. PeerChat rooms work on all your devices at the same time.

The macOS and Windows apps and the Linux AppImage update themselves. A .deb, .pacman or .apk updates when you install the newer one. On your phone it updates through the App Store or Google Play.

They overlap, but they aren't the same thing. Web3 usually means blockchains and tokens. The DWeb, the decentralized web, is a movement to give people back their data, their tools and their connections, and it cares more about the digital commons than about markets. PeerSky is part of the DWeb: it runs on peer-to-peer protocols like Hypercore and IPFS, with no blockchain or token needed. Mai Ishikawa Sutton's article The Debate Over DWeb vs. Web3 goes into where they meet and where they differ.
