About
Celerio is an original iOS Network Extension client. The packet tunnel, userspace TCP/UDP relay, DNS path, and encrypted transports run in Swift on the device.
Original transports
• SecureStream — TCP with system TLS or in-house SecureTLS, plus optional stream padding
• FastTunnel — QUIC / HTTP/3 with multiplexed TCP streams and UDP datagrams
• On-device stack — TUN I/O, IPv4, TCP/UDP relay, and DNS stay inside the Packet Tunnel
• Two-board desk — connect console on one page; tools and care on the next
Use the connect board to start or stop the tunnel, choose an endpoint, and apply smart routing. Membership unlocks the board for the billed window. The second board includes latency/DNS diagnosis, support tickets, terms, privacy, and updates.
