Canary

Repository size

Canary is a free and open-source MMORPG server emulator for the OpenTibia community, written in C++20 and Lua. It is a fork of the OTServBR-Global project. The repository includes the server core, datapacks, Lua scripts, database schema, build presets, automated tests and development tooling used by the project.

Getting Started

Wiki.

Docker Quickstart

Canary includes a lightweight Docker quickstart for running a local test server without compiling Canary locally. The stack starts MariaDB, the published Canary runtime image, MyAAC as the website/admin AAC, and opentibiabr/login-server as the client login webservice.

This quickstart is for local development, testing, and LAN demos. Do not expose it directly to the public Internet with the default test accounts and passwords.

Run from the docker directory:

cp .env.dist .env
docker compose up -d --build

The docker directory also provides guarded start scripts that start the stack and clean safe Docker leftovers without removing database volumes:

.\up.ps1

sh ./up.sh

Default local endpoints:

Website/admin: http://localhost:8080
Client login webservice: http://localhost:8088/login
Game port: 7172

MyAAC's login.php is intentionally removed from the quickstart image. Clients should use login-server only. See docs/docker/quickstart-for-beginners.md for a beginner guide and docker/DOCKER.md for the full setup, environment variables, test account, and troubleshooting guide.

Documentation

Docker beginner quickstart.
Multiprotocol runtime profiles. Covers the current, 11.00, and 8.60 runtime contracts, port layout, client preparation, and validation checklist.
System documentation.
Lua API reference and VSCode IntelliSense stubs. Canary generates these files from the C++ Lua bindings during startup when generateLuaApiDocs is enabled. The repository .luarc.json already adds docs/lua-api to the Lua Language Server workspace library; for VSCode workspace settings, run tools/setup_vscode_lua_api.ps1.

Recommended Tools and Clients

Assets Editor. Use this as the single asset source of truth, then export legacy-compatible .dat/.spr packages for 8.60 clients from the same current asset set.
Remere's Map Editor.
OTClient Redemption.
Tibia Extended Client Library. Use this to prepare compatible 8.60/11.00 CipSoft clients with extended limits, config-driven login redirect, and per-client local state.
Game Client.

Nightly Packages

Development builds can be downloaded from GitHub Actions artifacts. They are useful for testing recent changes from the main branch, but may include behavior that is not present in stable releases yet.

Github Actions.

Running Tests

Tests can be run directly from the repository root using CMake test presets:

# Configure and build tests for your platform
cmake --preset linux-debug && cmake --build --preset linux-debug

# Run all tests
ctest --preset linux-debug

# For other platforms use:
# ctest --preset macos-debug
# ctest --preset windows-debug

For detailed testing information including adding tests and framework usage, see tests/README.md.
