OpenKiosk

OpenKiosk turns a computer into a public browser terminal, with remote management and controls for browsing and session behavior. It is best suited to organizations that can deploy and administer Linux devices. The controls are unusually detailed for free software, though the current beta’s Debian 13 requirement limits where it fits.

Overview

OpenKiosk is a standalone public browser based on Mozilla Firefox, with system-level controls intended to restrict public users to web browsing. The maker says it has been deployed in venues and businesses since 2005, including libraries, schools, museums, hospitals, airports, hotels, and government offices. That breadth of use gives it a long deployment history, while the current release remains explicitly beta; organizations should weigh both when deciding whether it is ready for their own terminals.

The current release is version 151.0.4 Beta. Its installation instructions require Debian 13 (trixie) and an existing system user named openkiosk. The documentation covers x86_64 and aarch64 devices, including Raspberry Pi 5, and says other Linux distributions are planned for future support. That makes it a practical candidate for teams able to standardize on the required setup, but a poor fit for deployments that need a current installer across varied Linux systems.

Key features

A token registers a device for remote management through a web interface, where administrators can access settings for individual devices or all listed devices. Registration automatically removes the token from the device, so administrators need to save a backup token for managing devices. This supports centralized configuration, but token handling adds a small operational step to deployment.

Administrators can set fullscreen mode, hide or show the toolbar and URL bar, enable an on-screen keyboard, and decide whether bookmarks survive between sessions. Session controls include a timer and an ending countdown, plus choices about retaining cache, history, and cookies. Together, these give public-computing operators practical control over how long visitors browse and what carries over to the next person.

URL rules can allow or block sites. Strict mode also checks page resources, which can enforce tighter boundaries but may break pages when rules omit resources they need. Settings can disable local terminal access and start with a clean browser profile. Downloads and file uploads are labeled insecure options; enabling uploads gives web pages access to the terminal filesystem, so these controls call for careful configuration.

Custom branding can use custom.svg and splash.png files placed in /etc as root. The installer also offers optional Piper text-to-speech for website narration. The package is 555M and ships Danish, German, US English, Spanish, French, and Italian voices; it may suit touchscreen or accessibility needs, but adds a substantial download.

Pricing

OpenKiosk costs nothing. The plan is open source under the Mozilla Public License, self-hosted, and accepts donations. There are no paid tiers to unlock; the tradeoff is that organizations handle deployment and device management themselves, and the current beta’s Debian 13 requirement applies.

Platforms

The product is categorized for Linux, macOS, and Windows, and a separate download page lists packages for all three platforms at version 115.20.0, dated 2025-02-16. The current beta installation documentation is narrower: it targets Debian 13 on x86_64 or aarch64 hardware, with Raspberry Pi 5 instructions. Teams choosing a platform should distinguish those legacy desktop downloads from the current beta deployment path.

Who it's for

OpenKiosk is a strong fit for libraries, schools, museums, and other organizations operating shared public terminals that can standardize on Debian 13 and want control over device settings, browser sessions, and permitted URLs. Its session reset options and remote configuration are useful where computers serve many visitors. It is less suitable for teams that need a stable release, broad current Linux compatibility, or a managed service rather than self-hosted deployment.

Pros and cons

Pros

• Free and open source under the MPL, with no paid plan required for its kiosk controls.
• Remote settings for individual devices or all listed devices make it possible to manage registered terminals through a web interface.
• Session timers, clean-profile options, URL rules, and controls for browser interface elements address common needs on shared public computers.
• Documented x86_64 and aarch64 support includes Raspberry Pi 5 installation instructions.

Cons

• The current release is beta, so organizations seeking a stable release may prefer to wait.
• Current installation requires Debian 13 and a pre-existing openkiosk system user, limiting deployment flexibility.
• Strict URL filtering can break pages if required resources are omitted from the rules.
• Downloads and uploads are treated as insecure options, and uploads can expose the terminal filesystem to web pages.
• The optional text-to-speech package is 555M, a meaningful addition where storage or download size matters.

Alternatives

Choose Linutop Kiosk if you want a Linux and self-hosted option with a documented one-time installation price: its Linutop OS Pro installation with Linutop Kiosk costs €79, paid once for one PC or Raspberry Pi installation. For a hosted or mobile approach, FreeKiosk offers an Android app and cloud service, including a first-device cloud plan at 0.00 EUR billed forever.

KioskFrame is an iOS alternative with a free core kiosk browser and a paid fullscreen kiosk plan at $4.99 a month, billed monthly, with a 14-day free trial. UniKiosk is aimed at Android and web screens, with a free plan that includes unlimited screens and full kiosk lockdown. For a free Android and iOS option with paid monthly and yearly subscriptions, consider Kiosker.

If the need is asset lifecycle management and hardware and software license tracking rather than a public browser, SureAsset has a free plan with API access and automation. Kiosk is a free, open-source PDF reader. LimaxLock Secure Browser is an Android secure browser with a 14-day free trial and per-device pricing. The Kiosk Browsers and Kiosk Management Software lists can help compare more options.

Verdict

Choose OpenKiosk for a self-hosted public terminal where Linux deployment, remote device settings, and browser session controls are useful. Its current beta installation instructions target Debian 13, and the maker labels the product beta, so deployments should account for that status and requirement. Its strongest case is the depth of its free, open-source controls; organizations that need a stable release or broader current platform support should look elsewhere.
