Horizon Worlds is a social virtual reality platform built by Meta Platforms in which users create and explore three-dimensional spaces, play games, and socialize through customizable avatars. It opened to everyone aged 18 and over in the United States and Canada on December 9, 2021, after a roughly two-year invite-only beta.

The platform was a centerpiece of Meta's metaverse strategy after the company renamed itself from Facebook in October 2021. It began as a VR-only experience for the Meta Quest line of headsets, then added web and mobile clients in 2023. Despite a multi-billion-dollar investment, it struggled to retain users, and in early 2026 Meta announced it would refocus the platform on mobile.

Origins as Facebook Horizon

Meta announced the platform as Facebook Horizon at Oculus Connect 6 in September 2019, describing it as a social world built around user-generated content. It followed earlier Facebook VR social apps including Facebook Spaces, Oculus Rooms, and Oculus Venues. An invite-only beta opened in August 2020. On October 7, 2021, ahead of the company's broader rebrand, Facebook renamed the app Horizon Worlds and split off its live-events feature into a separate app, Horizon Venues.

Two related products carried the Horizon name. Horizon Workrooms, a remote-meeting app with virtual conference rooms, launched in open beta in August 2021. Horizon Venues, the live-events app for concerts and sports, was later folded back into Horizon Worlds.

Public launch and expansion

Horizon Worlds became available without an invite to users 18 and older in the United States and Canada on December 9, 2021, free of charge, running on Meta Quest 2 headsets. Support for the original Oculus Quest had ended on January 13, 2022. At launch Meta highlighted creator tools for building custom worlds and games, a personal Safe Zone reachable from a wrist menu, and Arena Clash, a 3v3 laser-tag game. The company had announced a 10 million US dollar Creator Fund in October 2021 to seed world-building.

The VR version reached the United Kingdom on June 17, 2022, Ireland and Iceland on July 13, 2022, and France and Spain (in English only) on August 16, 2022. In September 2023, Meta released the platform on mobile and the web in invite-only early access, available through the Meta Quest app on Android and through browsers on iOS and desktop. Meta recommended Google Chrome, Safari, and Microsoft Edge; Firefox was not supported. The mobile and web debut led with Super Rumble, a first-party shooter made by Meta's in-house studio, Ouro Interactive.

How it works

Users navigate Horizon Worlds as legged or, originally, legless avatars, moving between discrete "worlds" that other users or Meta build. The platform combines social hangout spaces, mini-games, and creation tools in one app. On VR headsets it uses motion controllers and spatial audio; on phones and desktop it is controlled with touch or keyboard and mouse, which lets non-VR users share the same worlds as headset wearers.

World creation was originally done with an in-headset editor. In February 2025 Meta released a Desktop Editor preview for Windows and began deprecating the in-headset tools; in September 2025 the desktop tool was renamed Horizon Studio.

From its 2021 launch through 2025, Horizon Worlds ran on the Unity game engine. At Meta Connect on September 17, 2025, the company introduced the Horizon Engine, a proprietary runtime built to replace Unity. Mark Zuckerberg said Meta had spent "the last couple of years" building it from scratch. Meta claimed the engine loaded worlds about four times faster and allowed more than 100 concurrent users in a single instance, several times the previous limit. Meta said the engine was built for persistent, cross-platform worlds that scale from cloud rendering down to a phone screen.

User adoption

In February 2022 Meta executives said during an all-hands meeting that Horizon Worlds and Horizon Venues together had about 300,000 monthly active users, with around 10,000 user-created worlds; a Meta spokesperson confirmed the figure to The Verge. Reporting at the time noted that combining the two products into one number prevented direct comparison with rivals such as Rec Room, which had cited more than 1 million monthly VR users about six months earlier.

Growth fell short of Meta's internal goals. In October 2022, The Wall Street Journal reported, based on internal documents, that monthly active users had fallen below 200,000 and that most visitors stopped using the app within their first month. By early 2026, the picture differed by platform: the analytics firm Appfigures reported the mobile app had reached about 45 million total downloads across iOS and Google Play, with 1.5 million in 2026 alone, though lifetime consumer spending on the app was only about 1.1 million US dollars.

The platform sat inside Meta's Reality Labs division, which by the company's own filings had accumulated operating losses past 60 billion US dollars from 2020 through 2024, including roughly a 5 billion dollar loss in the fourth quarter of 2024 alone.

Age policy and safety

Horizon Worlds launched as an adults-only (18+) service. On April 18, 2023, Meta opened it to teens aged 13 to 17 in the US and Canada, with safety defaults including private-by-default profiles, parental supervision tools through Family Center, limits on interactions between adults and unconnected teens, a voice mode that garbles a teen's voice for strangers, and content ratings that block teens from mature worlds and events.

Safety drew scrutiny early. After reports of avatars groping and harassing other users in late 2021, Meta promoted the Safe Zone tool and, in February 2022, introduced a "personal boundary," a default buffer of about four feet that stops other avatars from coming too close.

Avatars and the "legs" episode

Horizon Worlds avatars were initially rendered without legs, a limitation Meta attributed to the difficulty of tracking leg position from headset sensors alone. After a Zuckerberg avatar selfie posted in August 2022 was widely mocked for its crude graphics, Meta used its Connect 2022 keynote to announce avatar legs. On stage Zuckerberg said "legs are hard" and called them the most requested feature on the roadmap. The demo used motion capture rather than real headset tracking, and in-app legs rolled out only gradually afterward.

Mobile refocus and VR status

In January 2026, Meta said it would separate the VR and mobile sides of Horizon Worlds and make the platform a mobile-only experience, citing a larger audience and better reception on phones. The plan would have removed the VR app from the Quest store around March 31, 2026 and made it fully inaccessible in VR on June 15, 2026, repositioning the mobile app against Roblox-style social gaming and courting Roblox developers.

The decision drew immediate backlash, and Meta partly reversed it within days. On March 19, 2026, CTO Andrew Bosworth said in an Instagram Q&A, "We have decided, just today in fact, that we will keep Horizon Worlds working in VR," so existing VR worlds remain playable on Meta Quest headsets. Meta still said it would not develop new VR worlds and would concentrate resources on the mobile version, where Bosworth said there was "a much bigger audience."

Comparison to other social VR platforms

Horizon Worlds competes with other user-generated social VR services. Unlike VRChat, which allows users to import arbitrary custom 3D avatars and worlds and which predates it, Horizon Worlds uses Meta's own avatar system and a curated set of building tools tied to Meta accounts. Rec Room is another comparison point and reached larger VR user numbers earlier in the platform's life. Meta's later strategy explicitly aimed the mobile version at the audience served by Roblox.
