OpenTerminalUI OpenSource Self-Hosted Quant/Fundamental Analysis Toolset for
Built an open-source project called OpenTerminalUI — a terminal-inspired trading and market research workstation for NSE/BSE + US markets.

The idea started from frustration with fragmented tooling, expensive subscriptions, and dashboards that try to look modern but slow down serious workflows.
So I started building a keyboard-first, locally hosted, Bloomberg-inspired terminal experience focused on:
• Multi-chart workstation
• Quant/AST-based screeners
• F&O analytics
• Portfolio + risk tooling
• Backtesting workflows
• Command palette / GO bar navigation
• Model lab + stress testing
• Mock-data support for offline/local development
• Docker-first deployment
Tech stack:
• FastAPI + Python backend
• React + TypeScript frontend
• Dockerized setup
• Playwright + automated testing
One interesting part of this build:
A significant portion of the development workflow was AI-assisted using orchestrated multi-agent prompting across Claude Code, Codex CLI, and Gemini CLI running in parallel task flows. AI was extremely useful for scaffolding, repetitive implementation, and refactors — but still struggled heavily with domain-specific trading logic, real-time data flows, derivatives workflows, and edge-case reasoning.
That balance between “AI-generated velocity” and “human-engineered architecture” became one of the most interesting parts of the project.
This is still actively evolving, and I’d genuinely love:
• Feedback on UX/workflows
• Criticism from traders or engineers
• Ideas for terminal workflows
• Contributors interested in frontend/backend/quant infra
• Collaboration around open financial tooling
If you try it out, I’d be really happy to hear what feels useful, broken, overengineered, missing, or worth improving.
Would also love to collaborate with people interested in:
• Open-source fintech infra
• AI-assisted software engineering
• Trading systems
• Quant tooling
• Terminal-style UI/UX
• Self-hosted platforms
Feedback, PRs, architectural discussions, and harsh critiques are all welcome.
