Gloomberb: an open-source, keyboard-driven Bloomberg Terminal clone

Gloomberb is an open-source market-data terminal that pitches itself as a fast, extensible alternative to Bloomberg’s terminal, shipping as both a native desktop app and a text-based TUI. Its defining trait is a command-bar-first interface: users type a ticker or a short mnemonic to jump straight to a view — DES for security details, TOP for ranked market stories, QQ for a quote, HM for a heatmap, OMON for options. The mnemonic vocabulary is a deliberate nod to Bloomberg’s own function codes, aimed at traders who already think in those keystrokes.

The feature list spans most of what a professional data terminal offers: real-time quotes, charts, financials and SEC filings, institutional holders and 13F data, insider and congressional trading disclosures, analyst ratings, options monitoring, and relative valuation. It layers on market-wide context — global indices, FX crosses, yield curves, sector performance, a fear-and-greed gauge — plus portfolio risk, watchlists, broker connections, and alerts. Newer additions lean into current trends, including prediction-market data from Polymarket and Kalshi, AI-driven screeners, and a cloud chat assistant.

The significance is less about any single feature than the packaging: institutional-grade market tooling, keyboard-native and free to run, is a direct challenge to the roughly $25k/year Bloomberg subscription. One detail worth flagging for security-minded readers is the distribution model — installation is a piped curl … | bash shell script, and the marketing domain (gloom.sh) differs from the install host (gloomberb.com), the kind of run-arbitrary-code-from-the-internet pattern that warrants scrutiny before running it on a machine that touches brokerage credentials.
