Roku has introduced Roku Labs, an early-access programme for experimental applications built by its engineers. US viewers will reach the in-development experiences through a dedicated tile on the Roku home screen and can provide feedback before wider release decisions.

Initial concepts include portfolio, weather, custom-artwork and screensaver applications. Roku City Dash has already moved from the programme into general availability, giving the company one example of a prototype graduating into the main platform.

Roku also announced that the core of Roku LT OS, its lightweight operating system used in remotes and smart-home products, is now open source. That creates a separate developer path alongside the viewer-facing experiment programme.

Roku has not published selection criteria, telemetry boundaries, rollback controls or the open-source governance model. Platform teams will need those details to judge whether Labs is a controlled test environment or a broader production-distribution channel.
