Purism was founded in 2014[3] with the launch of a crowdfunding campaign for the Librem 15,[4] notable for being the first attempt at custom-manufacturing an Intel-based high-end laptop for GNU/Linux with freedom-respecting components.[5][6][7][8][9]

With the success of the initial crowdfunding campaign, a second campaign[10] was made for a 13-inch model of the Librem, where an additional focus on privacy was given with hardware kill switches built into the product design.[11] As the 15-inch model was still undergoing design and production, the kill switches feature was backported to it.

The two campaigns raised US$1,052,174 through the support of 1042 initial backers, which allowed the production and delivery of Librem laptops starting at the end of 2015.[12][13]

As campaign orders have gradually been fulfilled, Purism announced[14] that it would be transitioning from a purely build to order order fulfillment model to a build to stock model in 2017.

In February 2017, Purism transitioned to become a social purpose corporation, with its articles of incorporation detailing its social purpose.[15] The move was announced in May 2017.[16][17]

On August 24th 2017, Purism announced plans to build a smartphone, called the Librem 5.[18] This phone, with launch delayed to early April 2019, will feature baseband processor 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 has reached its goal two weeks before the end of the campaign.[19]



Purism manages the development of PureOS, a fully free GNU/Linux distribution based on Debian. PureOS mostly ships with software from the Debian repositories but has all software that violates Purism's guidelines removed. Most notably, the Mozilla Firefox web browser is rebranded as PureBrowser and ships with plugins to enhance user privacy. PureOS received endorsement from the Free Software Foundation in December 2017.[20][21] 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 GNU/Linux distributions and that owners have the freedom to install any operating system that they wish to install.[22]

Librem hardwareEdit

Librem 13 and Librem 15 laptopsEdit

Librem line of laptops is the flagship product of Purism. The Librem laptops come in two sizes, the 13 and the 15 featuring a 13 and a 15 inch screen, respectively. All of 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 the user 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 tabletEdit

Librem 11, sometimes referred to as Librem 10 or 12, is a proposed convertible tablet-to-laptop device. Librem 11 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 started in April 2016[23] and was suspended in October 2018.[24]

Librem 5 phoneEdit

On August 24th 2017, Purism launched a funding campaign for a $599 "security and privacy focused phone" Librem 5.[18] The 60-day funding campaign aimed to collect 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.[25][26] The phone would run entirely free firmware and software: Debian derivative with a choice of desktop environments GNOME[27] or KDE Plasma Mobile[28] or Ubuntu Touch[29]. Furthermore, unlike in any other phone, the baseband processor would 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 would feature hardware kill switches for the isolated baseband processor, Wi-Fi, Bluetooth, camera, and microphone.[30]

Librem KeyEdit

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 x 19 x 7 mm, and weights 6 g.[31]
