You're working fast or vibe-coding, the LLM is shipping faster than you can review, and three days later you're rotating AWS keys at 2am. LocalForge intercepts every git commit before it finalises. 3 layers: Rust regex blocks secrets in <1ms, CoreML on the Neural Engine catches unsafe patterns statistically, and a local Qwen LLM reviews your diff like a human and it's all fully offline on Apple Silicon. Nothing leaves your Mac.
