Chesswave Link Engines

Official chess engine release builds for Chesswave Link.

This repository packages open-source UCI chess engines for the platforms supported by Chesswave Link. Release assets are published as one .tar.gz archive per engine and platform.

Releases

GitHub Actions publishes release assets from .github/workflows/release-engines.yml.

Asset names do not include the release version because the GitHub release tag already provides it:

<engine>-<platform>.tar.gz

Examples:

stockfish-18-linux-x86_64.tar.gz
caissa-macos-silicon.tar.gz
patricia-windows-x86_64.tar.gz

Each archive contains the engine files at the archive root, without an extra wrapping directory or ./ path prefix.

Platforms

• linux-x86_64
• macos-silicon
• windows-x86_64

Not every engine is available on every platform. See each engine's engine.yaml for the exact platform matrix, binary name, and required companion files.

Build Types

Some engines are built from source in this repository with Docker-backed Makefile targets:

• caissa

Release-imported Linux engines use Dockerfiles where available so the CI path is consistent with source-built Linux engines.

Local Builds

Build one engine:

./scripts/build_one.sh caissa linux-x86_64 v1.0.0

Build every engine directory for a platform:

./scripts/build_all.sh v1.0.0 linux-x86_64

Build outputs are written to:

out/<version>/<platform>/<engine>/

Repository Layout

• .github/workflows/release-engines.yml - release workflow
• engines/<engine>/engine.yaml - engine metadata consumed by Chesswave Link
• engines/<engine>/Makefile - per-engine build or import entrypoint
• scripts/build_one.sh - build/import one engine for one platform
• scripts/build_all.sh - run build_one.sh for all engine directories
• scripts/import_release_asset.sh - import an upstream binary release asset

Licensing

Each engine remains licensed by its upstream project. Engine metadata includes homepage, source repository, license, and release provenance where available.
