ThinkWatch Lite

English | 中文

A local gateway for Claude Code, Codex and other AI clients, on macOS, Windows and Linux. Each client is connected once; after that, upstreams and models change without touching its configuration. Every request is recorded with its cost and route, and the API keys in it can be replaced before it leaves the machine.

Highlights

• Connect once, switch freely. Claude Code, Claude Desktop, Codex, opencode, Zed, Aider and DeepSeek Harness are pointed at the gateway in one step, with the change previewed, the original file backed up and a restore always available; Cursor, Continue and Antigravity CLI come with instructions. Switching upstreams then happens in the gateway alone.
• Keys replaced before sending, dangerous commands stopped. Outbound redaction swaps API keys, private keys, JWTs and connection-string passwords for placeholders before a request leaves, so a relay never sees them. Tool-call inspection cuts off download-and-run commands and the like, and hidden characters and prompt injection can be refused. The protections start in Observe and switch to Enforce one by one.
• MCP servers, skills and hooks, scanned. The MCP servers of eight clients side by side, with third-party servers marked, and a scan of client configuration, skills, hooks and project instructions for hidden characters, prompt injection, dangerous commands and overly broad permissions.
• Every request traceable. The rule a request matched, each upstream it tried, any conversion between API formats and how its cost was calculated; a finished request can be replayed against another upstream and compared side by side.
• Routing and failover. Rules by model, tools, images, extended thinking and more. When an upstream fails before the answer begins the next one takes over, and each session stays on one upstream so its prompt cache keeps hitting. Auxiliary requests such as title generation can be answered locally.
• Any upstream, any API format. API keys, Amazon Bedrock, ChatGPT and Z.ai accounts, relays such as OpenRouter and local models, with conversion between the Anthropic, OpenAI and Gemini APIs.
• Costs stated as they are. Estimated amounts are marked and requests without a price are counted separately instead of as zero.
• Remote core. The gateway can also run on a Linux server; the app connects to it over an encrypted control channel.

Install

The gateway, ThinkWatch Core, ships inside the app. The app is not signed by Apple or Microsoft, so the first launch needs one extra step; Install and update covers it, along with how updates arrive. The interface is in English and Simplified Chinese, and the app updates itself (a Homebrew installation updates through Homebrew).
