Brelyon

Brelyon is an MIT Media Lab spin-off building headset-free virtual displays — desktop monitors that use electro-optics and computational rendering to produce monocular image depth rather than autostereoscopic 3D. Its Ultra Reality line delivers a 122-inch virtual screen filling roughly 110 degrees of field of view, alongside Ultra Reality Extend (a multi-focal monitor that renders AI-generated overlays at different depths), Ultra Reality Mini, and experimental Hyper Displays. The company is headquartered in San Mateo, California with an international office in Taichung, Taiwan, and sells into enterprise simulation, training, teleoperation and medical visualization; prosumer flight simulation, gaming, trading and content production; and automotive in-vehicle HMI integration. Brelyon ships desktop software (Brelyon Suite, Focal Studio, Visual Engine, Stream Weaver) for distortion correction, monitor merging and multi-focal content creation, but publishes no public developer program, API, or SDK.

Brelyon is profiled on the APIs.io network. Tagged areas include Company, Displays, Hardware, Immersive Technology, and Virtual Reality.

Brelyon’s developer surface includes support, engineering blog, signup flow, pricing, YouTube channel, and 5 more developer resources.

  detail: Brelyon sells headset-free display hardware plus end-user desktop software (Brelyon Suite, Focal Studio, Visual
    Engine) and publishes no developer surface at all — brelyon.com/api, /docs and /developers all 404, api./docs./developer./mcp.brelyon.com
    do not resolve, and the only machine-readable endpoint on the domain is the WordPress core + WooCommerce REST index at
    /wp-json/, which is the marketing CMS rather than a product API.
