Platforms
Prebuilt binaries, where published, cover:
| Component | Targets |
|---|---|
| NullHub | 7 targets: Linux x86_64/aarch64/riscv64, macOS x86_64/aarch64, Windows x86_64/aarch64 |
| NullWatch | 7 targets: Linux x86_64/aarch64/riscv64, macOS x86_64/aarch64, Windows x86_64/aarch64 |
| NullClaw | Linux, macOS, Windows across ARM, x86 and RISC-V |
| nllclw | Linux, macOS, Windows, Android |
NullClaw additionally documents Android via Termux. The shared release pipeline (NullBuilder) cross-compiles up to 12 targets across 5 OS families — Linux (incl. arm32 and riscv64), Android, macOS, Windows — so coverage tends to widen with each release. NullDesk's CI builds its TUI/core for macOS, Linux, FreeBSD, Windows and Android, but publishes no artifacts yet.
Toolchain
| Requirement | Value |
|---|---|
| Zig | 0.16.0 exactly — repos pin it; newer or older will not build |
| Runtime dependencies | none (static binaries; SQLite vendored where used) |
| NullHub build extra | npm (embedded Svelte UI) |
| NullHub runtime extra | curl, tar (auto-installed if missing) |
What composes with what
| Integration | Status |

Binary sizes quoted around the family (4.4–6.5 MB NullClaw, 313–653 KB NullWatch, 842 KiB–1.23 MB nllclw) come from the release assets on GitHub; runtime memory figures are self-reported by the projects.
