Curated Technology Horror

Technology horror, also called techno-horror, is a subgenre of horror and science fiction that uses technology as the source of fear. The threat can be direct (killer machines, rogue AI, cursed media) or indirect (technology enabling surveillance, exploitation, or control). Films in this space often serve as cautionary tales rooted in the anxieties of whatever era they were made in. Frankenstein is one of the earliest examples; today, the subgenre covers AI, social media, and the dark web.

Most horror subgenres use supernatural or human threats. Technology horror is distinct because the dread is tied to real things people actually use every day: phones, the internet, cameras, AI systems. That familiarity is what gives it its edge. A ghost in a haunted house requires some suspension of disbelief. A killer who found your address through a hacked webcam does not.

Screenlife horror is a format within technology horror where the entire film unfolds on a computer or phone screen. The story is told through video calls, chat windows, browser searches, and social media. Unfriended (2014) is the most widely known example. The format exploits the interfaces people already find mildly paranoia-inducing and turns them into horror set pieces.

If you're new to the subgenre, a few films cover the range well. Videodrome (1983) is the defining early entry, exploring media consumption and body horror. The Ring (2002) uses cursed media in a way that still works. Ex Machina (2014) is the essential AI horror film. Host (2020) is lean, effective, and uses Zoom as its entire stage. Each of these represents a different era and angle within tech horror.

The core themes track closely with cultural anxieties about technology at the time a film is made. Privacy loss, surveillance, AI consciousness, online anonymity, social media toxicity, dependence on devices, and the erosion of the line between the digital and physical world are the most recurring. Films from the early internet era focused on the fear of the unknown online. Contemporary tech horror has shifted toward AI, deepfakes, and platform manipulation.

HorroRated evaluates tech horror films individually, scoring each one on its own merits rather than ranking them by popularity or streaming algorithm. Every entry in the Tech Horror collection gets a HorroRated verdict, a summary of what the film is actually doing thematically, and honest notes on who it's for. The goal is to surface films worth your time, including overlooked ones that didn't get wide theatrical releases.

They overlap heavily but aren't the same thing. Sci-fi horror is the broader category, covering anything from alien invasions to biological experiments. Technology horror is more specific: the technology itself has to be central to the threat, not just the backdrop. Ex Machina is both. Alien is sci-fi horror but not really technology horror. The distinction matters when you're trying to find films that tap into a specific kind of dread tied to the things we actually build and use.

The subgenre has always reflected real-world anxieties, and right now there are plenty of them. AI generating convincing fake media, surveillance infrastructure expanding quietly, social platforms optimizing for outrage, and algorithmic systems making life-affecting decisions without human review all give tech horror filmmakers more raw material than any previous era. The best films in the current wave aren't just scary; they're uncomfortable because they're not entirely fictional.
