A CLI and TUI for HEY.

Read and send emails, manage boxes, calendars, todos, habits, time tracking, and journal entries — all from your terminal.

Install

Requires Go 1.26+. Use mise to install the correct version:

mise install # install Go 1.26
make install # build and install into /usr/local/bin/hey

Authentication

# Browser-based OAuth via Launchpad (primary method)
hey auth login
# Or use a pre-generated token
hey auth login --token TOKEN
# Or use a browser session cookie
hey auth login --cookie COOKIE

Tokens refresh automatically on expiry. Credentials are stored in the system keyring (with file fallback at ~/.config/hey-cli/credentials.json).

hey auth status # check auth status
hey auth token # print access token for scripting
hey auth refresh # force token refresh
hey auth logout# clear credentials

TUI

Run hey to launch the interactive terminal UI.

Navigate between mailboxes, postings, and full email threads. Use Enter to drill in, Escape/Backspace to go back, and / to filter lists.

CLI Commands

All commands support --json for raw JSON output and --base-url to override the server URL.
