Experimental tooling

Labs

Early tools and prototypes from the Strowger workshop. They are useful, experimental, and clearly labeled so you know what you are installing.

01 · Browser

Strowger Browser

A local browser appliance for Strowger workflows: a real Chromium runtime, a local broker, isolated realms, and an MCP endpoint for agents running on your Mac.

v0.4.8 · macOS arm64 · experimental

Lab build — unsigned and not notarized.

This package is for testing on Apple Silicon Macs. macOS may block it because it is not signed by Apple. The package contains the application code and runtime, but no user credentials, passkeys, pairing tickets, vault, identity, or browser profile. Those are created locally, if needed, on first use.

Download

Install

In Terminal, download the installer and verify it before running it:

curl -fL -O https://lic.strowger.io/download/Strowger-Browser-0.4.8-macos-arm64.pkg
curl -fL -O https://lic.strowger.io/download/Strowger-Browser-0.4.8-macos-arm64.pkg.sha256
shasum -a 256 -c Strowger-Browser-0.4.8-macos-arm64.pkg.sha256

Because this is an unsigned lab build, remove the quarantine attribute and install it:

xattr -d com.apple.quarantine Strowger-Browser-0.4.8-macos-arm64.pkg 2>/dev/null || true
sudo installer -pkg Strowger-Browser-0.4.8-macos-arm64.pkg -target /

The installer initializes or migrates the local realm and installs the manager. After installation completes, inspect the local realm:

APP="/Applications/Strowger Browser.app"
NODE="$APP/Contents/Resources/runtime/bin/node"
CONTROL="$APP/Contents/Resources/macos/control.mjs"
"$NODE" "$CONTROL" realms status local

Connect Codex

To expose the local MCP endpoint to Codex:

APP="/Applications/Strowger Browser.app"
NODE="$APP/Contents/Resources/runtime/bin/node"
CONTROL="$APP/Contents/Resources/macos/control.mjs"
PORT_FILE="$HOME/Library/Application Support/Strowger Browser/realms/local/runtime/local-worker.json"
PORT="$("$NODE" -e 'const fs=require("node:fs"); process.stdout.write(String(JSON.parse(fs.readFileSync(process.argv[1], "utf8")).port));' "$PORT_FILE")"
"$NODE" "$CONTROL" configure-mcp local codex strowger-browser codex "$PORT" private

Restart Codex after the configuration command so it discovers the browser tools. The local endpoint is loopback-only; any local process running as your user can request control of it.

02 · What is next

More experiments soon.

Labs is where Strowger ships early tools, prototypes, and one-off utilities before they become part of the main product. Each release includes its platform, version, checksum, and limitations.
