LibreBooking vs Okena

LibreBooking is an open-source resource scheduling system for organizations that manage reservations. It supports bookings across multiple resources, waitlists and recurring bookings, with check-in for reservations. Role-based access controls, reservation quotas and credits, and granular usage reports help organizations manage access and track use. The interface is described as mobile-friendly and responsive, with custom themes and color schemes. Calendar integration with Outlook and Thunderbird uses ICS; authentication guides cover LDAP, Active Directory, OAuth2 and SAML. An optional RESTful JSON API supports third-party integrations, automation or client applications, and the project provides documentation for custom plugins. Organizations can install a prebuilt release, deploy with Docker, or install manually. Manual installation requires PHP 8.2 or later, Apache 2.4 or later, and MySQL 8.0 or MariaDB 10.6 or later; other web servers are not currently supported or tested. LibreBooking is free, licensed under GPL-3.0, and available for Linux, self-hosted and web use. The README warns that versions earlier than 7.0.0 have a critical vulnerability that can permit unauthenticated administrator account takeover; it says to upgrade to 7.0.0 or later immediately.

Okena is a native terminal multiplexer for running multiple command-line agents and projects in one window. Workspaces can be arranged as side-by-side project columns, tabs, split panes, detachable terminal windows, or fullscreen. The terminal uses GPU-accelerated rendering and supports scrollback of up to 100,000 lines. Okena can save and restore workspace layouts and terminal sessions across restarts; persistence is local. Users can manage Git worktrees as projects and view branches and change statistics. Documented integrations include status or usage information for Claude Code and OpenAI Codex, Docker Compose project services, and opening files in editors. Remote control is documented through a local HTTP and WebSocket API, with a browser client and iOS and Android companion apps. Pairing uses HMAC-SHA256 token authentication and rate-limited pairing codes, and downloaded updates are SHA256 verified. Okena is free and open source under the MIT License, with a listed plan of free. Installation commands are provided for macOS, Linux, and Windows, alongside instructions for building from source.
