Loup Lite 1.27.0
Official Loup Lite build 1.27.0 from Code Craft AI: the free public build of Loup, for educational and training purposes. It contains the Loup toolchain and standard library and, of Loup's cryptography library, only its hash functions (loup.crypto.hash: SHA-2, SHA-3 and SHAKE, cSHAKE, BLAKE2, BLAKE3) — no encryption, MACs, key derivation, signatures, key exchange or TLS, and not the full set of Loup packages. Customers: get the full release from https://code-craft.ai/loup/download.
Each archive holds the Loup toolchain (loup, the trusted Stage0 compiler loup-bootstrap) and the Loup Wasm runtime loup-launcher: run host scripts with loup run, build applications with loup-bootstrap build.
Install
Linux and macOS:
curl -fsSL https://github.com/code-craft-ai-company/loup-releases/releases/download/v1.27.0/loup-install.sh | sh -s -- --version 1.27.0Windows (PowerShell):

Loup Lite 1.26.0
Official Loup Lite build 1.26.0 from Code Craft AI: the free public build of Loup, for educational and training purposes. It contains the Loup toolchain and standard library, but not Loup's cryptography library (encryption, signatures, key exchange, TLS) and not the full set of Loup packages; its only cryptographic function is SHA-256 hashing. Customers: get the full release from https://code-craft.ai/loup/download.
Each archive holds the Loup toolchain (loup, the trusted Stage0 compiler loup-bootstrap) and the Loup Wasm runtime loup-launcher: run host scripts with loup run, build applications with loup-bootstrap build.

Loup Lite 1.25.2
Official Loup Lite build 1.25.2 from Code Craft AI: the free public build of Loup, for
educational and training purposes. It contains no encryption or decryption functionality: it
