HASA Coding Agent

Free, local-first AI coding agent for VS Code. Bring your own API key — Nara, Zen, Gemini, Groq, or any OpenAI-compatible router — and pick from free models.

Like Cline: install, paste a key, chat. Diffs open in VS Code's native diff editor.

Install

Search HASA in the Extensions view and hit Install. Or:

code --install-extension hasa.hasa-vscode-ext

Setup (30 seconds)

Ctrl+Shift+P → HASA: Setup API Key & Model → pick provider → paste key → pick model (Free badge = $0).
Ctrl+Shift+P → HASA: Open Chat.

Your key is stored only on this machine (%USERPROFILE%\.hasa\config.json on Windows, ~/.hasa/config.json elsewhere). Env vars (NARA_API_KEY, ZEN_API_KEY, GEMINI_API_KEY, GROQ_API_KEY) override the file.

Commands

Command	What it does
`HASA: Open Chat`	Open the chat panel beside your code
`HASA: Setup API Key & Model`	Switch provider / key / model anytime
`HASA: Show Diff`	Preview current file in the native diff editor

Safety

Every destructive action (write_file, edit_file, run_shell) asks first: once / session / always-for-project. All tool calls are logged to ~/.hasa/sessions/*.json. Keys are sent only to your provider's host — never anywhere else.

Same config as the terminal

hasa-agent CLI and this extension share one config file, so setup in one place configures both:

npm install -g hasa-agent
hasa setup
