SBproxy

Last modified: 2026-08-03

SBproxy is an open source Enterprise AI Gateway for API, MCP and agent, and AI model traffic. Every feature in this repository ships under Apache-2.0.

Start here

Install a release on Linux or Apple Silicon macOS:

curl -fsSL https://download.sbproxy.dev | sh
export PATH="$HOME/.local/bin:$PATH"
sbproxy --version

The installer writes to ~/.local/bin by default. Keep the export in your shell profile if that directory was not already on PATH. Linux amd64, Linux arm64, and Apple Silicon macOS arm64 have release archives. Intel Macs can use the Linux image in Docker or build from source. See the runtime manual for the complete install matrix and checksums.

Run the credential-free gateway example next. It starts a local upstream, puts an API behind the gateway, adds an MCP tool, then sends a local OpenAI-compatible completion through the same listener.

git clone https://github.com/soapbucket/sbproxy
cd sbproxy

Follow the getting-started guide.

Install alternatives

Homebrew:

brew tap soapbucket/tap
brew install sbproxy

Docker. The published image has no default configuration command, so mount the file and name the command:

docker pull soapbucket/sbproxy:latest
docker run --rm -p 8080:8080 \
  -v "$PWD/sb.yml:/etc/sbproxy/sb.yml:ro" \
  soapbucket/sbproxy:latest serve -f /etc/sbproxy/sb.yml

Build from source when you need a local development binary:

make build-release
target/release/sbproxy --version

Documentation and examples

Documentation index groups the guides by first run, traffic type, operations, and reference material. The examples/ directory contains complete configurations. For the configuration schema, use configuration.md; for the command surface, use manual.md.
