Purism is a computer technology company based in South San Francisco, California and registered as a social purpose corporation in the state of Washington. Purism manufactures the Librem personal computing devices with a focus on software freedom, computer security, and Internet privacy.
Purism was founded in 2014 with the launch of a crowdfunding campaign for the Librem 15, notable for being the first attempt at custom-manufacturing an Intel-based high-end laptop for Linux with freedom-respecting components.
With the success of the initial crowdfunding campaign, a second campaign was made for a 13-inch model of the Librem, where privacy was improved further via hardware kill switches built into the product design. The 15-inch model was still undergoing design and production, so the kill switch feature was backported to it.
On August 24 2017, Purism announced plans to build a smartphone, named the Librem 5. This phone, with launch delayed to early April 2019, will feature baseband processor (BP or BBP) separate from the main CPU and hardware kill switches for the baseband, Wi-Fi, Bluetooth, camera, and microphone. Further, this phone would run entirely free and open-source software. Purism announced a crowdfunding effort for the phone that would run 60 days, intended to collect US$1.5 million. Purism reached its goal two weeks before the end of the campaign.
Purism manages development of PureOS, a fully free Linux distribution based on Debian. PureOS mostly ships with software from the Debian software repository but has all software removed that violates Purism's guidelines. Most notably, the Mozilla Firefox web browser is rebranded as PureBrowser and ships with plug-ins to enhance user privacy. PureOS was endorsed by the Free Software Foundation in December 2017. Librem laptops ship with PureOS by default and an optional Qubes OS USB drive. Purism says that it is easy for Librem owners to install alternative Linux distributions and that owners have the freedom to install any operating system that they wish to install.
Purism has announced that it will run an app store for PureOS that will offer Microsoft software including Windows. Applications will be rated on a scale representing maturity, which ranges from early development to products that have been approved for default inclusion.
Librem 13 and 15 laptops
Librem line of laptops is the flagship product of Purism. The Librem laptops come in two sizes: the 13 and the 15 feature a 13 and a 15 inch screen, respectively. These products ship with Purism's own operating system, PureOS, a derivative of Debian GNU/Linux, and an optional Qubes OS USB drive. Purism's products also feature hardware kill switches to allow users to shut off the camera, Wi-Fi, Bluetooth, and the cellular modem on products that have one (or can be purchased air gapped).

Librem 11 tablet
Librem 11, sometimes termed Librem 10 or 12, is a proposed convertible tablet-to-laptop device. It would have an 11-inch touch screen in an 11.6-inch body with a detachable keyboard, and an optional docking station. Development on the device began in April 2016 and was suspended in October 2018.
Librem 5 phone
On August 24, 2017, Purism launched a funding campaign for a $599 "security and privacy focused phone" Librem 5. The 60-day funding campaign aimed to collect US$1.5 million, however the goal was surpassed two weeks early and concluded with US$2,677,609.10 raised, 78% over the target. The phone would run entirely free firmware and software: Debian derivative with a choice of desktop environments GNOME or KDE Plasma Mobile or Ubuntu Touch. Further, unlike in any other phone, the baseband processor will be separated from the CPU main bus and instead connected via a fast USB interface, thus isolated from the main CPU RAM bus. Also, the phone will feature hardware kill switches for the isolated baseband processor, Wi-Fi, Bluetooth, camera, and microphone.
Librem Key is a hardware USB security token supporting multiple features, including integration with tamper-evident Heads BIOS that ensures Librem laptop BIOS was not maliciously altered since the last laptop launch, and one-time password storage (3x HOTP (RFC 4226), 15 x TOTP (RFC 6238)), integrated password manager (16 entries), 40 kbit/s true random number generator, and tamper-resistant smart card. The key supports type A USB 2.0, has dimensions of 48 mm × 19 mm × 7 mm (1.89 in × 0.75 in × 0.28 in), and weights 6 grams (0.21 oz).
