Who it is forA developer who uses Claude Code or Codex and wants to change API keys, relays or models without reconfiguring each client every time.
The problemEvery upstream change normally means editing the configuration of each AI client by hand, and a mistake can break the client.
The outcomeThe client is connected to the local gateway a single time, and later upstream and model changes happen only inside the gateway.
What you need first
- A supported computer: macOS 12 or later on Apple silicon, Windows 10 21H2 or later, or a Linux x86_64 or aarch64 machine
- At least one upstream you already have access to, such as an API key, a relay, or a local model
- The AI client you want to connect, such as Claude Code or Codex, already installed
Steps
- Install the app on macOS with
brew install --cask thinkwatchproject/tap/thinkwatch-lite, or download the installer for your platform from the latest GitHub release. - On first launch, follow the extra step in the install guide, since the app is not signed by Apple or Microsoft.
- Open the app and connect Claude Code or Codex in one step, reviewing the previewed change; the original file is backed up and can be restored.
- Add your upstreams in the gateway, such as an API key, a relay or a local model.
- Change the upstream or model in the gateway and send a test prompt from the client to confirm it answers.
Prompt for your agent
Using the repo ThinkWatchProject/ThinkWatch-Lite, connect <client name, e.g. Claude Code> to the local gateway, add the upstream <upstream name> in the gateway, and switch to it without editing the client's configuration again. Expected output: a test request from the client that completes through the new upstream. Verify that the client's original config file exists as a backup.
Caveat. The README says the app is not signed by Apple or Microsoft, so the first launch needs an extra step described in the install guide.
