Caelo.
A VPN client for subscription links. One link, every device, no account.
- No account. Paste a subscription link and connect. Caelo never asks who you are.
- No telemetry. The only thing it sends on its own is a request for this page's update manifest, identical from every installation — and you can turn that off.
- AmneziaWG. WireGuard with traffic shaping, so the handshake does not look like a handshake.
- Free software, GPL-3.0-or-later, all of it readable.
Download — 0.2.1 (build 13)
macOS Disk image, signed and notarised. Drag Caelo into Applications. Windows Installer for 64-bit Windows. See the note below. Linux AppImage — one file, runs anywhere, installs nothing. Android Most phones from the last several years. Android (any) Larger, but works on every architecture.About the Windows build
Windows will warn you, and it is right to.
The installer carries no commercial code-signing certificate, so SmartScreen
says the publisher is unknown. Everything works — but do not take that on
faith. Every file above is listed with its SHA-256 in
latest.json, so you can check that what you
downloaded is what we published:
certutil -hashfile Caelo-0.2.1-windows-x64-setup.exe SHA256
macOS is signed with a Developer ID and notarised by Apple, and opens without
ceremony.
Updates
macOS updates itself. Linux packages come from your package manager, and the AppImage updates in place. Caelo checks by fetching one static file from this site; the request carries no identifier, is the same from every installation, and goes through the tunnel when one is up. Settings turns it off.
