In 2010, former Limewire lead engineer Adam Fisk observed that many of the networking techniques used for P2P filesharing could be applied to help people living under internet censorship, and he founded the project that would eventually become Lantern. The first version of Lantern was released shortly thereafter as open source software. Early development was supported by the Open Technology Fund, a U.S. nonprofit which has also backed The Tor Project and Signal, among other internet freedom technologies.
By 2016, Lantern had amassed over two million monthly active users in China. Many users discovered that Lantern was particularly effective for bypassing China's "Great Firewall" internet censorship regime. Lantern had become so popular with local internet freedom activists that they referred to it by a nickname – 蓝灯, meaning "Blue Light."
Over the years, the team at Lantern pioneered a number of techniques now considered fundamental to internet censorship circumvention, including domain fronting and TLS Masquerade. Lantern engineers have co-authored research with contributors from the University of California, Berkeley and Psiphon (Citizen Lab), among other institutions.
Lantern has provided critical internet access during many of the most perilous human rights crises of the decade. In 2022, amid widespread internet disruptions by the Iranian government in response to the “Women, Life, Freedom” protest movement, Lantern provided 13% of the total available internet bandwidth in Iran.
In 2026, Lantern launched Lantern VPN – the product you're reading about right now. Lantern VPN provides Western users with the same privacy and security properties that activists in high-risk circumstances have relied on for over a decade – and, via its peer-to-peer volunteer computing technology known as Action Mode, makes it possible for anyone to join the fight against digital repression around the world.
