Overview / Description
Bunker is an AI local workspace tool that runs private chat, code assistance, and agent workflows entirely on your Mac for developers and knowledge workers who need privacy by default. Built around Apple Silicon, Bunker lets you download and run curated local AI models directly on your device — no cloud account required for core workflows, and no data leaving your machine during normal use. The workspace consolidates chat, code editing, project memory, and agent tasks into one native macOS application, making it the best AI local workspace for Mac developers who want to keep sensitive projects off cloud servers.
The agent coding capability lets you ask Bunker to reason across an entire project, propose file changes, edit files, and show you exactly what changed before anything is applied — giving you full review control over every action. Local model management is built in: you browse a curated list of models optimized for Apple Silicon, download the one you need, and switch between them without leaving the app. Project memory keeps relevant context available across sessions so you don't have to re-explain your codebase each time you start. All of these capabilities run from a single refined interface designed for the native macOS experience, using local inference rather than routing your prompts to a third-party API. Bunker also supports offline use, since its core AI workflows are designed to run without an internet connection once models are downloaded.
Used For
Bunker is used by Mac developers and knowledge workers to run private AI chat, code assistance, and agent-driven file editing locally on Apple Silicon, without relying on cloud AI services.
