OpenKiosk

OpenKiosk is a free, open-source browser terminal for turning shared machines into managed public browsing stations. It is best suited to organizations prepared to administer Linux devices and tune their browsing and session rules. Its control set is substantial for a no-cost tool, but the current beta’s Debian 13 requirement sharply limits where it fits.

Overview

Built on Mozilla Firefox, OpenKiosk runs as a system-integrated standalone browser, with controls intended to keep public users within web browsing rather than local terminal access. The maker says it has been deployed in public venues and businesses since 2005, including libraries, schools, museums, hospitals, airports, hotels, and government settings. That breadth of use is encouraging, but it does not remove the need to account for the current beta status: the maker asks users to test the software and send bug reports.

OpenKiosk is self-hosted and open source under the Mozilla Public License. Its current release is 151.0.4 Beta, and current installation instructions require Debian 13 (trixie) plus an existing system user named openkiosk. The combination favors teams with Linux administration capacity, not organizations seeking a broadly compatible desktop installer for the latest release.

Key features

Remote management lets administrators register devices with a token, then reach settings for an individual device or all listed devices through a web interface. A successful registration removes the token from the device, so administrators need to preserve a backup token for device management. That process supports centralized configuration, but token handling deserves care during setup.

Kiosk settings cover fullscreen display, toolbar and URL-bar visibility, and an on-screen keyboard. Administrators can also configure session timers and an ending countdown, choose whether bookmarks survive sessions, and determine whether cache, history, and cookies persist. These controls let a venue shape the browsing experience and clean up user data between sessions without treating every public terminal as an unrestricted desktop.

URL rules can allow or block sites. Strict filtering also checks resources loaded within a page, which can tighten restrictions but may break pages when rules omit required resources. The software can disable local terminal access and start with a clean browser profile. Downloads and uploads are options the maker labels insecure; uploads can give web pages access to the terminal filesystem, so enabling them carries a meaningful security trade-off.

Organizations can customize the boot screen with custom.svg and splash.png files placed in /etc as root. The installer also offers an optional 555M PiperTTS package for website narration, with Danish, German, US English, Spanish, French, and Italian languages. These additions are useful for branded or narrated terminals, though the TTS package is a substantial optional install.

Pricing

OpenKiosk costs nothing. The OpenKiosk plan includes the open-source software under MPL, with donations accepted; there is no paid tier or subscription term to weigh. Its zero price does not eliminate operating costs: deployment is self-hosted and requires compatible hardware, Debian 13, and system administration.

Platforms

The current beta installation path is for Linux on x86_64 or aarch64 hardware, with installation instructions for Raspberry Pi 5. Debian 13 is required; support for other Linux distributions is planned for the future. Although separate downloads list Windows, macOS, and Linux packages for version 115.20.0 dated 2025-02-16, those are distinct legacy desktop packages rather than the current beta installation path.

Who it's for

OpenKiosk makes sense for libraries, schools, museums, and other public-facing organizations that can manage Debian-based terminals and want fine-grained control over sessions, URLs, and device settings without a license fee. It is a weaker fit for teams that require a stable release, support for their existing non-Debian Linux setup, or an uncomplicated cross-platform installation. Organizations should also be comfortable managing self-hosted devices and making deliberate security choices around downloads and uploads.

Pros and cons

• Pros: The MPL-licensed software is free, and remote management can expose settings for one or all registered devices.
• Pros: Session timers, data-persistence controls, URL allowlists or blocklists, and terminal-access restrictions give administrators practical ways to shape public use.
• Pros: x86_64 and aarch64 support, including Raspberry Pi 5 instructions, gives Linux deployments a choice of hardware.
• Cons: The current release is beta and requires Debian 13, limiting suitability for organizations that need a mature release or another Linux distribution.
• Cons: Strict URL filtering can break pages when their required resources are not allowed, so tighter rules may require careful maintenance.
• Cons: Enabling uploads can expose the terminal filesystem to web pages, and the maker likewise flags downloads as insecure.

Alternatives

For a device-management need rather than a public browser, SureAsset is a free option with asset lifecycle management, hardware and software license tracking, and API access and automation across desktop, mobile, and web platforms.

Kiosk is a free open-source PDF reader, making it a better match when reading PDFs—not configuring public browser terminals—is the goal. FreeKiosk is worth comparing for Android and cloud kiosk deployments; its first cloud device is free forever, while its Android app supports Android 8.0 and later.

For iOS, KioskFrame offers a free core kiosk browser with no time limit, plus a paid plan with a 14-day trial. UniKiosk is an Android and web alternative with a free plan per screen that includes unlimited screens and full kiosk lockdown.

Organizations seeking paid, multi-platform management could consider Hexnode Kiosk Browser, whose paid plans start at $2.20 a month and include a 15-device starting allocation. Kiosker is another paid-subscription option for Android and iOS, with monthly and yearly plans and a seven-day trial. For Windows-focused deployments, SiteKiosk is a paid alternative with an annual maintenance renewal option for its Windows Classic license.

Verdict

Choose OpenKiosk if your organization can run Debian 13 terminals and wants a free, open-source public browser with remote configuration and meaningful session controls. The main reason to choose it is the breadth of kiosk restrictions without a license charge; the main reason to look elsewhere is the beta release and narrow current installation requirement.
