polymarket-tui

A fast, keyboard-driven terminal client for Polymarket: browse markets, watch live order books and trades, chart prices, track your portfolio and P&L, follow traders, and place orders - without leaving the terminal.

_{▶ Watch the interactive demo - browse markets, open a live book, chart, search.}

Built with Python 3.12 and Textual.

Install

PyPI (installs the CLI in an isolated environment):

uv tool install polymarket-tui   # or: pipx install polymarket-tui / pip install polymarket-tui

One-line install (installs uv if missing, then installs polymarket-tui as a uv tool):

curl -sSL https://raw.githubusercontent.com/byronxlg/polymarket-tui/main/install.sh | bash

Homebrew (one command - auto-taps and installs):

brew install byronxlg/tap/polymarket-tui

Add --HEAD to track main instead of the latest release.

From source (for development):

git clone https://github.com/byronxlg/polymarket-tui
cd polymarket-tui
uv sync
uv run polymarket-tui

Then run polymarket-tui.

No credentials needed to browse: markets, books, charts, trades, comments, and any trader's public positions all work read-only.

Landing page

A static landing page lives in site/ and deploys to GitHub Pages (https://byronxlg.github.io/polymarket-tui/). Its hero plays a recorded asciinema demo of the TUI - browse markets, open one, cursor the live book, chart, search. Preview it locally with python3 -m http.server -d site 8000, and regenerate the demo with bash scripts/record_demo.sh. See site/README.md.

Account setup

Press A in the app (a pop-out - esc drops you back where you were):

• Funder address only -> observer mode: your positions, P&L, activity. This is the wallet address shown on your polymarket.com profile (also your USDC deposit address).

• Funder + private key -> trading mode. Where the key comes from depends on how you log in to Polymarket:

  • email/Magic login: polymarket.com -> Settings -> Export Private Key (signature type 1, the default)
  • browser wallet: export the key from the wallet itself, e.g. MetaMask account details (signature type 2)
  • trading straight from your own wallet with no Polymarket proxy: that wallet's key, funder = the same address (signature type 0)

  Applied credentials are saved to ~/.config/polymarket-tui/credentials.toml (chmod 600, plaintext - treat the file like the key itself). POLYMARKET_* env vars override the file.

  Note: accounts created since Polymarket switched to Privy embedded wallets export only a threshold-key share; the trading API (and therefore this client) does not support them yet.

Orders are dry-run until you go live: fully validated and signed but never posted. Live posting requires the L toggle (confirmed) or POLYMARKET_EXECUTION_LIVE=1; the choice persists across sessions and a LIVE start is announced. Every placed/cancelled order is appended to ~/.local/share/polymarket-tui/orders.jsonl.

Deposits, withdrawals, token approvals, and redemption of resolved positions are on-chain operations this client does not perform - use the website.

Keys

One scheme everywhere - press ? in the app for the full reference:

• arrows move; up/down flow into adjacent panels (category bar, chart inspect, search box); right/enter open; left/esc step out one level (order panel -> expanded view -> screen -> previous screen)
• tab cycles the screen's selector: category (home), chart timeframe (event/market), pane (portfolio), results mode (search)
• space is the contextual toggle: star an event, follow a trader, flip the YES/NO book, flip BUY/SELL while ordering, show rules
• Market pages: b/s order entry under the live book (price in cents, empty = market order, up/down = tick), y/n book side, a expand the inline trades to full width (right opens the trader), i rules, c comments, e parent event
• / search (markets and traders), p portfolio, w watchlist, A auth, L toggle DRY/LIVE for the session (going live asks for confirmation), q quit

Data sources

Public Polymarket APIs: gamma-api.polymarket.com (markets, events, search, comments), clob.polymarket.com (order books, price history, orders), data-api.polymarket.com (positions, trades, activity), user-pnl-api.polymarket.com (profit history). Trading uses py-clob-client-v2 for CLOB V2 order signing.
