Best Free & Open Source Alternatives to Bloomberg Terminal

Gloomberb is an open-source finance terminal that brings Bloomberg-style market research to your desktop and terminal. It ships as a native desktop app for macOS and Windows, a terminal UI (TUI) for macOS, Linux, and Windows, plus a browser app, all sharing the same command language and plugin system.

Research features cover quotes, price charts, fundamentals and financials, SEC filings, options (implied-volatility surfaces and term structure), realized volatility and volatility cones, analyst ratings, CFTC positioning, futures curves, FX, global indices, economic events, and market scanners. You also get news feeds, portfolios, watchlists, broker connections, alerts, notes, and built-in AI tools.

Unlike the Bloomberg Terminal, which costs roughly $30,000 per year and is a closed, proprietary system, Gloomberb is MIT-licensed, free to run, and extensible. Its Bloomberg-inspired command language (DES, GP, OVDV, HVG, COT, TOP, WIRP, BTMM, CTM) makes it familiar for ex-Bloomberg users. Free market data is rate-limited and delayed by 15 minutes in the browser app; a Gloom Cloud Pro subscription unlocks realtime data, while the desktop app and TUI support plugin-provided and broker-provided data.

It is built with TypeScript and OpenTUI, installable via Homebrew, a shell script, or Bun, and requires a Kitty-compatible terminal (Ghostty, Kitty, or WezTerm) for graphics in the TUI. A CLI (gloomberb quote AAPL --json) supports scripting and automation.

OpenBB is an open-source financial data platform designed as a modern alternative to expensive proprietary terminals like Bloomberg. It provides a unified interface to access market data, economic data, fundamental analysis, technical analysis, and portfolio management tools.

Built with Python, OpenBB integrates with dozens of financial data providers and supports AI-powered workflows via its agent-friendly API. It runs as a web application or can be used programmatically, making it suitable for individual investors, quants, and enterprise teams alike.

With over 64,000 GitHub stars, OpenBB is the most popular open-source financial terminal. It supports extensions for crypto, forex, equities, fixed income, macroeconomics, and more — all customizable and self-hostable.

What is Fincept Terminal?

Fincept Terminal is a native cross-platform desktop terminal for financial research, analytics, and trading. It ships as a single binary built in C++20 with a Qt6 user interface and an embedded Python 3.11 runtime for analytics — no Electron, no browser runtime, no Node.js dependency.

The free edition (this repository, AGPL-3.0) targets students, hobbyists and academic researchers. Fincept Corporation also sells a proprietary Enterprise edition on top of the same data core with deeper history, live broker routing, private datasets, SSO/SAML, RBAC and audit logs.

Features

• Analytics — DCF valuation, portfolio optimisation, VaR / Sharpe / Sortino, derivatives pricing, fixed-income tools, and an 18-module QuantLib suite.
• AI agents — 37 agents across trading, investing, economics and geopolitics. Bring your own key for OpenAI, Anthropic, Gemini, Groq, DeepSeek, OpenRouter and Ollama.
• Data — 100+ connectors including FRED, IMF, World Bank, DBnomics, AkShare, Polygon, Kraken, Yahoo Finance, and various government APIs.
• Trading — crypto and equity feeds, paper-trading engine, and 16 broker integrations.
• Automation — visual node editor, MCP tools, and an AI Quant Lab with ML, factor discovery and reinforcement learning.
• Global intelligence — maritime tracking, geopolitical analysis and relationship mapping.

Self-hosting

The project ships signed installers for Windows (x64), Linux (AppImage, .deb, .rpm) and macOS (Apple Silicon), plus a Dockerfile and setup.sh for building from source on Linux/macOS. The toolchain is pinned (CMake 3.27.7, Ninja 1.11.1, Qt 6.8.3, Python 3.11.9).

How it compares to Bloomberg Terminal

Bloomberg Terminal is the institutional standard but costs roughly $27,000 per user per year. Fincept Terminal covers the same workflow surface — equity research, portfolio analytics, news, charting, market data — on top of free public feeds and your own API keys. The open build is AGPL-3.0, which is strong copyleft and not appropriate for proprietary forks; Fincept sells a paid Enterprise edition for firms that need private data and live trading without copyleft obligations. For retail investors and academics who do not need point-in-time data, broker routing or SSO, Fincept Terminal is a credible free alternative to Bloomberg, LSEG Workspace, Koyfin and TradingView Premium.

License

Ticker is a command-line and terminal UI (TUI) app for watching stock, crypto, and derivatives prices in real time while tracking the value of your positions. You give it a watchlist and it renders live quotes in your terminal, refreshing on a configurable interval (5 seconds by default).

It pulls quotes from Yahoo Finance by default and from Coinbase for symbols suffixed .CB, streaming Coinbase spot data over a WebSocket; .X suffixes resolve to short aliases maintained by the project. You can track cost-basis lots (quantity, unit cost, brokerage fee), split watchlists and lots into groups, convert values into a local ISO 4217 currency, and display pre- and post-market prices, open/previous close/day range, position weights, and portfolio totals. Extras include sorting modes, custom hex color schemes, a shared local cache for faster startup, and ticker print for JSON or CSV position output.

Compared with paid terminals such as Bloomberg Terminal, TradingView, Koyfin, or LSEG Workspace, Ticker deliberately does little: no charts, no fundamental research, no news. It is a fast, keyboard-driven quote monitor and position tracker for people who already know what they want to watch. It is GPL-3.0, installs from Homebrew, winget, snap, Docker, or prebuilt binaries, and keeps your watchlist and portfolio in a local YAML file.

Open Terminal is a self-hosted financial research tool built for individual investors. It provides a Bloomberg-style interface that connects directly to SEC filings, live stock prices, and AI-powered analysis — all without the Bloomberg price tag.

The platform aggregates financial data into an in-memory DuckDB database served through a Flask backend. Features include:

• Financials tab: Chart revenues, net income, and other GAAP concepts alongside stock prices for selected tickers.
• Companies directory: Browse thousands of public companies with LLM-generated summaries and sector tags.
• Quadrant analysis: Compare companies across two financial dimensions simultaneously on a scatter plot.
• AI Playground: Ask plain-English questions and get SQL queries generated against the financial database via OpenRouter.
• SQL Explorer: Direct DuckDB query access for power users.

Data is pre-processed into parquet files from SEC EDGAR and Polygon.io sources. The app runs on Python with a vanilla JavaScript frontend.

Compared to Bloomberg Terminal, Open Terminal is free, self-hosted, and aimed at retail investors rather than institutional traders. It lacks real-time market data depth but offers SEC fundamentals and AI query generation at no cost.

Equibles is a self-hosted financial data server that speaks the Model Context Protocol, so an AI assistant can query company fundamentals, ownership, trading activity, and macro data directly instead of you copying numbers between browser tabs. The AGPL-3.0 core is written in C# on .NET 10 and ships as a Docker Compose stack: ParadeDB for storage, a worker that scrapes the public sources on a schedule, a web portal at port 8080 for browsing, and an MCP endpoint at port 8081.

Out of the box it ingests SEC EDGAR filings and XBRL financial statements, 13F institutional holdings, Form 3/4/5 and Form 144 insider data, House and Senate congressional trade disclosures, fund and adviser filings (NPORT, N-CEN, Form D, Form ADV), SEC and FINRA short data, FRED economic indicators, CFTC Commitments of Traders positioning, CBOE volatility and put/call ratios, USAspending contract awards, the FDA advisory-committee calendar, and daily OHLCV prices from Yahoo Finance. It also imports verified European listings keyed by ISIN and venue. That data is exposed through 70 MCP tools, and the web portal adds charts with technical indicators, holder screeners, insider and short-activity leaderboards, and CSV export.

It is aimed at analysts, quants, and developers who want terminal-grade reference data in an AI workflow without paying for a Bloomberg terminal, and who would rather own the database than rent API calls from Koyfin, LSEG Workspace, or TradingView. The trade-off is that this is a research corpus, not a trading feed: prices are end-of-day, 13F data arrives with the SEC's filing lag, and the self-hosted build leaves out live quotes, options chains, earnings-call transcripts, and the market-wide screener. Those live in the paid Equibles Cloud, which runs the same core against a pre-backfilled, always-current database.
