pupa-backend

FastAPI / LangGraph backend that powers the Pupa iOS / macOS client. Speaks plain AG-UI over a single POST / SSE stream; pair-once auth keeps a long-lived token in each device's Keychain. Runs locally next to the client, or in the cloud (Railway + Postgres).

Install

Install from PyPI with uv (isolated tool venv, puts the pupa-backend CLI on your PATH):

uv tool install pupa-backend            # latest
uv tool install pupa-backend==0.0.72    # pin to match your app

Quick start

pupa-backend run              # start the backend on :8004
pupa-backend pair             # mint a QR pairing code for your iPhone
pupa-backend status           # is it running?
pupa-backend service-install  # run as launchd / systemd background service

LLM credentials (AWS Bedrock, Anthropic, or any OpenAI-compatible endpoint) live in your shell environment, never in the config file. Configuration is written by pupa-backend setup to ~/.pupa-backend/config.yml.

Auth model

The backend requires auth by default — the only client credential is a paired-device token in the iOS Keychain. Set PUPA_API_KEY server-side, run pupa-backend pair for an 8-char code, and pair from the app. For a same-laptop dev loop only, PUPA_AUTH_DISABLED=1 skips auth entirely (never on a reachable backend).
