You can connect Tidewave Web directly to GitHub Copilot CLI. The GitHub Copilot subscription will give you access to models from Anthropic, OpenAI, xAI, and other providers.
Simply open up Tidewave Web settings, choose the Providers tab, choose "GitHub Copilot" and click "Connect". Next we will automatically download and install the Copilot CLI for you. Once connected, we will automatically configure the Copilot CLI to use Tidewave MCP. You may disable this option if (and only if) you have already customized the Copilot CLI to use Tidewave MCP.
You can control which Copilot models are available to Tidewave in your GitHub Copilot settings.
Copilot through OpenCode
You can also use GitHub Copilot with OpenCode. First connect Tidewave to OpenCode. Once connceted, select "Add models", and then pick GitHub as one of the providers. See our OpenCode documentation to learn more.
Custom copilot-cli installation
It is possible to use a custom copilot executable by setting the TIDEWAVE_COPILOT_CLI_EXECUTABLE environment variable when starting your web application. This is rarely needed in practice but it may be required in some operating systems like NixOS.
BYOK not supported
While GitHub Copilot does support bringing your own key (BYOK), this functionality is not available via ACP (the protocol Tidewave uses to communicate with the
copilotCLI) at the moment. Consider using OpenCode or Codex instead.
