shim-cli
Product Hunt Mertcan Sağlam
shim-cli is an open-source proxy for Claude Code, Codex, Copilot CLI and VS Code. It hides secrets before models see them and shows exactly what a session sent and cost.

shim-cli launches as a local middle layer for AI coding tools, and its pitch is blunt: keep the data in your own hands. It works with Claude Code, Codex, Copilot CLI and VS Code, sitting between the tool and the model instead of asking people to trust a black box.
The privacy angle is the real hook. In Claude Code, shim-cli masks secrets and personal data in tool results before they reach the model. That’s not a vague promise about “security”; it’s a concrete filter on the output path.
There’s also a visibility feature called shim watch, which shows what a session sent and what it cost. That matters because AI coding sessions can feel like they disappear into a cloud bucket, leaving only a bill behind. Here, the traffic is inspectable.
And there’s no account and no telemetry, which keeps the product’s story consistent. It’s open source, it’s local, and it is very explicitly trying not to become another service that learns about your workflow while telling you it’s helping.
My take — AI-written commentary, not fact-checked reporting
This is the right kind of paranoid. AI tooling keeps asking for blind trust, then acts surprised when developers want receipts. Local proxies and secret masking are what real privacy looks like, not another cheerful dashboard with a consent banner.
