OpenBB vs. Streamlit
Streamlit gets prototypes off the ground fast. OpenBB gets financial analytics into production with modular dashboards, finance-specific widgets, and AI agents that scale securely.
The Streamlit Tradeoff
Streamlit is excellent for getting a single developer from notebook to prototype fast. OpenBB picks up where those prototypes stop. With finance-specific widgets instead of bare-bones components, a native Copilot and chat experience instead of ad‑hoc AI wiring, OpenBB offers a Workspace designed for teams and scalable, production-ready applications.
Why financial teams choose
OpenBB over Streamlit
Pre-built widgets for financial analysis
Streamlit provides generic components (buttons, sliders, and basic charts), requiring you to build finance-specific tools from scratch. OpenBB ships with purpose-built widgets for time-series data, pricing grids, and interactive controls, letting you focus on proprietary logic rather than UI primitives.
Production-ready applications
Streamlit is great for prototyping, but scaling to production often demands a dedicated DevOps team. OpenBB is a turnkey workspace for enterprise deployment. Whether for internal tools or white-labeled client apps, it delivers secure, scalable infrastructure, no custom stack maintenance required.
Built-in AI chat experience
Streamlit provides basic chat elements, leaving you to build agent interfaces, context handling, and visualization logic from scratch. OpenBB offers a production-ready chat interface for any AI agent, plus a native Copilot engineered for finance. It understands your data, generates citations, creates visualizations on demand, and integrates with secure backend workflows out of the box.
Scalable architecture for teams
Streamlit apps are often isolated silos, making it difficult to share logic or enforce consistency across a team without duplicating code. OpenBB's modular backend allows you to build core analytics once and reuse them across multiple dashboards. This lets teams deploy standardized, updated tools instantly to all analysts without managing complex infrastructure or version conflicts.
Real-World Applications
from Macro to Crypto
Caíque Cober (macro researcher and developer at Terrapin) built over 50 Streamlit monitors covering cross-asset moves, energy flows, and short-term money markets before switching to OpenBB for his macro research workflow.
What he couldn't do in Streamlit: rearrange dashboards on the fly based on evolving macro narratives, maintain persistent analyst configurations without external databases, or deploy advanced AI copilots with chart generation and citation capabilities.
The result after rebuilding on OpenBB:
"It's the closest I've come to a workflow that feels truly customizable, shareable, auditable, and reproducible."

Matt Maximo (Investor at VanEck) built a crypto analytics dashboard in OpenBB that aggregates data from CoinGecko, Velodata, Glassnode, CCData, and Google Trends into a single workspace view. It uses custom widgets and parameters such as coin and date range, so he can adjust views without touching frontend code and package the setup as a reusable workflow for future research.
"Building this on OpenBB means I spend my time on data and models instead of wrestling with frontend code. The platform handles the UI, state, and layout, so my effort goes into improving the analytics, not maintaining a web app."

FAQs
Yes. Wrap your Python logic in FastAPI endpoints (a straightforward refactor), then map those endpoints to OpenBB widgets. The core analytical code remains largely unchanged.
To get started faster and see immediate value, you can also directly embed your existing, running Streamlit applications into an OpenBB dashboard using the iframe widget. This is the fastest way to unify your workflows, bringing your tools into a single view in minutes with zero code changes.
Yes. OpenBB supports custom widgets for specialized use cases, similar to Streamlit's custom component system.
It doesn't matter. OpenBB's frontend is backend-agnostic. It connects to any language or framework that can expose a REST API. While we provide examples using FastAPI for Python developers, it's an option, not a requirement. For example, this Polymarket App runs on a JavaScript backend.
OpenBB offers on-premises and private cloud deployment with enterprise-grade security controls, including SSO, role-based access, and audit logs. Your proprietary data never leaves your infrastructure.
Streamlit has a larger general-purpose community. OpenBB's community is smaller but focused on financial services, with examples, app templates, and integrations built for finance workflows — check them out on our Solutions page.
OpenBB provides responsive support for production deployments.
