June 2026 Summaries

RWX web apps enable teams to create shareable preview environments directly from RWX run definitions, offering an alternative to maintaining separate staging infrastructure for branches, pull requests, or automated changes. A web app task runs a long-lived server process on a public rwx.run URL, with configurable endpoints and ports, while idle applications automatically spin down and restart when accessed. Preview environments can include databases, caches, and other services through background processes, reusing existing Docker Compose configurations, installation steps, and build outputs. RWX also applies content-based caching to dependencies and generated assets, helping previews start quickly without dedicated images or snapshots, and provides both stable cache-key-pinned URLs for testing and friendly URLs that follow an endpoint’s latest build.
