Daily Stock Analysis is an open-source system that uses LLMs to generate comprehensive stock decision dashboards and deliver them to your messaging app of choice — automatically, every day at 6 PM Beijing time, with zero server infrastructure required. The entire system runs on GitHub Actions, triggered by a cron job from your own fork. Each daily run aggregates technical analysis, real-time price data, chip distribution, news sentiment, capital flow tracking, and fundamental data across A-shares, Hong Kong, and US markets. The output is a "decision dashboard" — a structured report with conclusions, risk alerts, buy/sell levels, and an action checklist — pushed via webhook to WeChat Work, Feishu, Telegram, Discord, Slack, or email. The project supports a wide range of LLM backends (DeepSeek, Qwen, Gemini, Claude, OpenAI-compatible APIs, local Ollama) and data sources (Tushare, AkShare, TickFlow). With 32,000+ GitHub stars and climbing, it's clearly scratching an itch for retail investors who want institutional-grade analysis without paying for Bloomberg.

LangAlpha
Open-source financial research agent that runs code instead of eating your context window

LangAlpha is an open-source financial research agent built on Claude and LangChain that takes a fundamentally different approach to financial data: instead of injecting raw price series or filings into the context window, it writes and executes Python code in Daytona cloud sandboxes. Five years of daily OHLCV data for 500 tickers would consume tens of thousands of tokens as raw text — as executed code, it consumes almost none. Research compounds across sessions via persistent "workspaces" (e.g., "Q2 rebalance," "NVDA earnings deep-dive"). The agent ships 23 pre-built slash-command skills: DCF modeling, earnings transcript analysis, SEC filing review, macro overlays, and more. The Programmatic Tool Calling (PTC) architecture means the agent drafts, runs, and iterates on analysis code rather than retrieving static answers — closer to how an actual analyst thinks. The indie team open-sourced under Apache 2.0 and the HN Show HN thread highlights strong interest from quant developers and independent RIAs. The architecture pattern — code execution over data injection — is broadly applicable beyond finance and represents a meaningful contribution to the agent design space.
Reviewer scorecard
“Using GitHub Actions as a cron-based LLM pipeline is genuinely clever — no server, no containers, no maintenance. Fork, add secrets, enable Actions, done. The multi-LLM backend support means you can run the whole thing on DeepSeek for almost nothing.”
“The PTC architecture is the right call — injecting raw financial time series into a context window was always the wrong abstraction. Persistent workspaces mean research actually accumulates instead of resetting each session. The 23 pre-built skills cover 80% of what a junior analyst does daily. Fork-worthy even if you don't use it as-is.”
“LLMs hallucinate stock data. Without rigorous validation against ground truth prices and alerts, 'AI-generated buy/sell levels' are at best noise and at worst a way to lose money with extra steps. Use this for learning, not trading.”
“Sandbox code execution on financial data raises real questions: how are API keys and brokerage credentials handled? Daytona sandbox cold starts could introduce latency in time-sensitive analysis. And 'AI-written Python for DCF models' needs robust human review — errors in financial models compound in bad ways.”
“Democratizing systematic multi-market analysis that previously required either a quant team or a Bloomberg terminal is a big deal. The GitHub Actions architecture is a template for a whole class of personal AI automation.”
“The code-execution-over-data-injection pattern is going to become standard for data-heavy agent domains: genomics, legal discovery, supply chain analytics. LangAlpha is proving it in finance first, and the open-source architecture gives the community a reference implementation to fork for other verticals.”
“The notification to Telegram or Feishu is a nice touch — your daily market brief lands in the same app as your messages. It's the kind of ambient intelligence that makes you feel like you have a well-informed analyst on call.”
“For independent researchers and finance content creators, this is a serious productivity unlock — structured analysis that compounds over time instead of starting from scratch each session. The slash-command UX is clean and the output is already formatted for presentation.”
