Dayon! is a remote desktop assistance application designed for helping another person with their computer. Its emphasis is on straightforward support sessions rather than running a permanent remote administration service or maintaining a catalogue of managed hosts.
The software includes both the assistant and assisted roles in one package. Connection handling is intended to minimize configuration for the person receiving help, while its screen-transfer approach is designed to remain usable when network bandwidth is limited.
This is free and open source software.
Key Features
- Combines the assistant and assisted sides of a support session in the same application package.
- Normally requires no router or network configuration on the computer receiving assistance.
- Protects remote assistance traffic with end-to-end encryption using TLS 1.3.
- Uses compressed and cached screen images to reduce bandwidth consumption during remote sessions.
- Can transmit the remote display using greyscale imagery when minimizing network traffic is more important than colour.
- Provides interactive remote control so the assistant can operate the other computer when permission is granted.
- Uses STUN to help determine the network arrangement when systems are behind NAT.
- Can use TURN infrastructure when a direct connection cannot be established between the two systems.
- Supports reversing connection establishment to accommodate restrictive network configurations.
- Can identify situations where both computers are on the same private network and make use of the local path.
- Provides a multilingual interface for assisting users who work in different languages.
- Supports colour screen transmission as well as bandwidth-saving greyscale images.
- Does not require users to register an account before establishing remote assistance sessions.
- Cross-platform support – runs on Linux, macOS, and Windows.
