Libki

Libki is a free system for managing timed access to shared computers, reservations, and print workflows. It is best suited to libraries and school labs with staff able to run a server and maintain workstation clients. Its library-oriented access controls are a strong fit; organizations seeking hosted service or minimal infrastructure should look elsewhere.

Overview

Libki gives administrators a web interface for managing users and session time, messaging or banning users, and checking which client computers are occupied or available. That central view can help a public-computing team coordinate a busy lab, while the self-hosted deployment puts server upkeep on the organization rather than a vendor.

Access can be first-come-first-served, reservation-based, or a mix. That lets a site adapt to local demand, though it does not remove the need to deploy and manage Libki clients on the workstations.

Key features

Users can see remaining session time and log off early. At the end of a session, the client can log off the operating system or reboot, giving administrators a way to reset shared computers between users. The client supports Windows and Linux; Windows has an installer, while other operating systems require compiling from source, a meaningful setup burden for less technical teams.

Libki supports SIP2 and LDAP single sign-on. With SIP2, access can be restricted using patron status flags, fees, age groups, and other configured fields; its manual also covers SIP2 configuration for Koha and Evergreen hold notifications. This makes it a more natural match for libraries with those workflows than a basic kiosk lock-down system. Print management is available for controlled clients or through file uploads to the server.

Administrators can configure history anonymization and retention, as well as automatic deletion of inactive users. Retention settings left empty keep data indefinitely, so the organization needs to make and maintain an explicit retention policy rather than assume old records will disappear.

Pricing

Libki is free open-source software: its Libki plan costs nothing and can be downloaded, installed, and used without a software charge. There is no free trial because there is no paid plan to trial, and there are no paid-plan seat limits or quotas described. That makes it accessible to organizations willing to supply their own infrastructure and administration.

The maker says support or development services may be purchased, with custom pricing. Those services are separate from the free software, so teams that need outside implementation or ongoing help should account for that potential cost.

Platforms

Libki is listed for Linux, self-hosted, web, and Windows. The server is self-hosted; the manual recommends Debian Linux, Ubuntu Server, or Docker, and Docker requires a separate database server. The server has no native SSL support, so the manual recommends a reverse proxy with SSL termination. These requirements make Libki a better fit for an organization with server-management capacity than for a site seeking a ready-hosted service.

Who it's for

Libraries and school computer laboratories are the clearest fit, especially where staff need timed public access, reservations, patron-based controls, or shared-computer printing. Organizations without staff to maintain Linux or Docker deployment, database infrastructure, workstation clients, and SSL termination are less likely to benefit from the no-cost license.

Pros and cons

• Pros: Free open-source use avoids software fees, while timed sessions, reservations, and web-based administration address core needs of managed public computers.
• Pros: SIP2 and LDAP support, plus SIP2 controls using patron fields, can align access with library identity and lending workflows.
• Pros: Configurable logoff or reboot and print management cover practical needs of shared workstations.
• Cons: Self-hosting, a separate database for Docker, and reverse-proxy SSL termination require infrastructure work that a hosted product would handle.
• Cons: Windows is the only client platform with an installer; other operating systems require compiling from source.
• Cons: Empty retention settings preserve data indefinitely, so administrators must actively configure retention and anonymization.

Alternatives

OpenKiosk is another free option for Linux, macOS, and Windows; choose it when those platforms and an MPL-licensed, donation-supported kiosk product suit the need better than Libki's library-specific controls.

KioskCore may suit teams prioritizing device monitoring: its free plan covers up to 2 devices, 7-day metric history, on-demand screen capture with 24-hour retention, and 3 email alerts per device per day, with community support.

Quantem Kiosk Software is a paid alternative with a $2.40 a month Essential plan billed per device per month; its listed allowance includes QR enrollment, one private app up to 50 MB, three console users, and five scheduled reports. It is worth considering when those device-management allowances matter more than Libki's public-computer session model.

Trio Kiosk Management offers a 14-day free trial on its Essentials plan at $5 per device per month, starting with 20 devices. It may be a better fit for a team that wants a time-limited trial and paid device-based management.

Kiosk is also free, with a broad platform list including Android, iOS, Linux, macOS, web, and Windows; its listed description is for an open-source PDF reader, so it is not a direct substitute for Libki's session-management role.

SureAsset has a free plan for asset lifecycle management, hardware and software license tracking, API access, and automation; choose it when tracking assets rather than controlling public workstation sessions is the priority.

KioskSide is a paid alternative.

Canopy is a paid option with a Starter plan at $2,500 a month, a 12-month minimum contract, and a 500-device starting point; it targets a substantially different scale and commitment.

Verdict

Libki is a strong choice for libraries and school labs that want no-cost, self-hosted management of public computer sessions and can support its server and clients. Its SIP2 controls and flexible access modes are compelling for that setting. Look elsewhere if you need vendor-hosted infrastructure, straightforward cross-platform client installation, or a setup that avoids security and retention administration.
