Apache Guacamole

What Apache Guacamole is

Apache Guacamole is a free, open-source remote desktop gateway for accessing desktops through a web browser. It supports VNC, RDP, and SSH; after installation on a server, users can connect without browser plugins or separate client software. The desktops may be hosted in the cloud rather than physically present. The project documents native and Docker installation methods, and supports access from web browsers, mobile phones, and tablets. File transfer and session recording are supported. Guacamole provides documented core APIs for integration into open-source or proprietary applications. Authentication extensions listed in the manual cover Active Directory or LDAP, multi-factor authentication, single sign-on, smart cards and certificates, vault secrets, and RADIUS. The software is licensed under Apache License, Version 2.0. The manual recommends encrypting communication between users and Guacamole with SSL/TLS and using a mechanism to prevent brute-force attacks. SSH and SFTP server identity verification is not enabled by default, though it can be configured with known-hosts data or connection parameters. Community help is available through public mailing lists, which require subscription before posting. The current release is version 1.6.0, dated 2025-06-22.
