LibreBooking vs Séance

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.

Séance is a free, Linux-only terminal multiplexer for tracking AI coding-agent sessions. It follows Claude Code, Codex, Pi, OpenCode, and Antigravity CLI sessions, and shows whether each is working, awaiting permission, or idle. Permission requests and task completions can generate desktop notifications with unread tracking. Its panes scroll horizontally, with workspaces, tabs within columns, a command palette, focus-follows-mouse, and session persistence across restarts. The app uses GTK4, libadwaita, and libghostty, and supports X11 and Wayland. The `seance ctl` command connects to a running instance over a Unix domain socket; commands can return JSON, manage workspaces and panes, send input, and read terminal output. The project states that it has no telemetry and is licensed under MIT. Installation options include Arch Linux AUR, a Nix flake, and an x86_64 AppImage. OpenCode remote attach sessions and `--pure` launches are not tracked. Séance is pre-1.0, and only the latest release receives security fixes.
