SoLo is a runtime loader embedded in static musl binaries that lets them dlopen() and use glibc-linked system libraries—specifically GPU drivers—without containers or a second libc. The trick: it implements its own ELF mapper and a glibc ABI shim over musl, so a fully static executable can call into host libraries like Mesa/Vulkan while staying a single inspectable binary. The proof is concrete: a static Vulkan compute demo runs unmodified on AMD, Intel, and NVIDIA GPUs by loading the distro's native driver at runtime. The repo ships buildable source, CI validates against 2,100+ real Debian library objects on x86-64 and aarch64, and the code is deliberately small and readable—the interesting pieces fit in three files. The scope is honest: load-once, two architectures, explicit stubs for unsupported glibc symbols that fail loudly rather than corrupt, and no claim to handle every ABI edge case. It's positioned as solving the "static binaries vs. GPU drivers" friction without the bloat of AppImage or containers.
