Valve Releases 1.07-GiB Lepton on Steam as Steam Frame Summer 2026 Window Narrows

Summary
Valve has made Lepton public on Steam and released FEX at nearly the same time, exposing two key compatibility layers built for its upcoming Steam Frame headset.
Lepton runs Android apps in Linux containers with limited overhead, while FEX translates 32-bit and 64-bit x86 code to ARM64; Steam Frame uses both alongside Proton for Windows compatibility.
Steam developers can now ship Android depots with APK and optional OBB files, mark Android as a supported OS, and use Steam Cloud for saves stored in Android external data directories.
The 1.07 GiB Lepton package appears as a free Linux service tool rather than a normal store app, reinforcing that it is a background component of Valve's software stack.
Because Valve has only said Steam Frame will launch in summer 2026, the public rollout of these tools is one of the clearest signs the headset's remaining launch window is closing.
