Bring proprietary tools into OpenBB Workspace with the new HTML Widget

December 15, 2025 — 4 MIN

Bring proprietary tools into OpenBB Workspace with the new HTML Widget

HTML widgets represent a fundamental shift in how you can customize and extend the OpenBB Workspace. Instead of being limited to our pre-built widget types, this new architecture allows institutional clients to integrate fully interactive, sandboxed tools using any web technology they prefer.

We are effectively shipping two distinct capabilities for OpenBB Workspace users:

  • Enterprise/On-Prem: Full JavaScript execution enabled, allowing for complete interactive capabilities (buttons, forms, real-time data).

  • Cloud (pro.openbb.co): HTML and CSS only, focused on secure, high-fidelity visualization without script execution.

Unify your fragmented stack without “porting” code

In most financial firms, the workflow is fragmented. An analyst might have a terminal open for market data, a web browser for internal risk models, a Jupyter notebook for backtesting, and a separate window for AI chat. This constant context switching kills productivity and fractures insights.

HTML widgets solve this by allowing you to merge your proprietary, in-house tools directly into the OpenBB Workspace.

Financial professionals already have tools they’ve built. Quant teams have sophisticated D3 risk visualizations; developers maintain internal web components; data scientists have Plotly dashboards. Until now, bringing those assets into a unified workspace meant rebuilding them from scratch to fit a vendor's proprietary system.

By treating your internal applications as widgets, they live side-by-side with our advanced pre-built visualization tools. More importantly, they exist within the same context as the OpenBB Copilot or any other AI agent your firm would like to integrate. This means an analyst can view your firm’s custom risk model, compare it against market data, and ask an AI agent to synthesize findings across both, all in a single pane of glass.

We are removing the barrier between "buy" and "build." You no longer have to choose between a vendor platform and your own custom stack; you get the efficiency of a unified workspace without sacrificing the specificity of your internal tools.

Two Deployment Models

Enterprise/On-prem

For clients running their own instances, we enable the full suite of capabilities. This allows your developers to build widgets that act as complete operational tools, submitting orders, updating internal databases, or running real-time simulations.

Cloud

On pro.openbb.co, we disable JavaScript execution. This might sound restrictive, but it remains incredibly powerful. You can still:

  • Export visualizations from Jupyter notebooks as static HTML.
  • Build complex layouts that our standard grid system doesn't support.
  • Apply custom CSS for branded reports and dashboards that match your firm's identity (with white labeled solutions available).

Two approaches to integrate with AI

Getting an LLM to "see" what is inside a custom HTML widget is difficult because raw HTML is often too noisy for AI to parse effectively. We have designed two specific integration patterns to solve this.

See this in action with a custom crypto order book widget below. Notice how the Copilot seamlessly interprets the market depth data to answer natural language questions.

1. The Raw Endpoint (recommended)

This approach is similar to the mechanism we allow for Plotly charts.

You implement a raw=true parameter on your widget's backend endpoint. When the AI is invoked, we don't scrape the HTML; instead, we hit your endpoint with that parameter, and you return a structured JSON response.

This is the best solution to get clean separation of concerns, one view for the human (HTML), one for the machine (JSON).

2. Direct HTML Parsing

Alternatively, if your widget doesn't implement a raw endpoint, the AI will parse the HTML structure directly.

While this works, structured endpoints provide cleaner results. LLMs can struggle with nested HTML, so we recommend implementing the raw endpoint when accuracy is critical for your use case.

Real-World Scenarios

We are already seeing how this flexibility changes workflows:

Quant Teams: A team that spent months building a D3.js risk analysis tool was told they would need to rebuild it to use our platform. With HTML widgets, they simply dropped their existing files into the widget, and it worked immediately.

Data Science: Teams using Plotly Dash for internal tools can now export specific components as standalone HTML and embed them into shared dashboards.

Custom Branding: A firm needed reporting dashboards that strictly adhered to their brand fonts and colors. HTML widgets gave them the freedom to apply custom CSS and achieve pixel-perfect control over every visual element.

HTML widgets are about removing friction. Instead of forcing you to build our way; we're providing the foundation for you to keep yours.

OpenBB belongs to everyone

Didier Lopes

Founder & CEO, OpenBB


TL;DR: We are open-sourcing the entire OpenBB product suite under a permissive open source license

Today is bittersweet.

On December 20, 2020, over the Christmas holidays, I wrote the first lines of Gamestonk Terminal, what would eventually become OpenBB. My flight home to visit my parents had been cancelled because of COVID, so I stayed in London and started building a tool to streamline my own investment research process.

At the time, the idea was simple: individuals (and firms) should be able to own their research platforms. They shouldn't have to adapt their workflows to whatever a data or software vendor decided to build. They should own the entire experience - from the data they connect to, to the interface analysts and PMs use every day, to the APIs, models, skills, tools and AI agents that increasingly form part of the investment process.

Over the last almost six years, OpenBB evolved far beyond anything I imagined when writing those first lines of code. We started as an open-source terminal and went on to build the SDK (now Open Data Platform), the OpenBB Bot, the OpenBB Workspace, the OpenBB Copilot, the Excel Add-in, and an ecosystem of applications created by our team, our partners and the community.

We kept innovating and being at the forefront of what user experience should be. I was prepared to die on the hill that if we were to become the financial infrastructure software for the buy-side and sell-side, then we could not monetize data. Monetizing data would have made us a data vendor. The margins would have been higher, but the incentive would have shifted from offering a better UI/UX to selling more datasets. Selling an infrastructure platform is incredibly challenging, for many reasons. And so we died on that hill. Along the way, we built an incredible community, reached millions of people through our open-source project, worked with some of the largest financial institutions in the world and assembled a team that consistently built far beyond what should have been possible for a company of 10 people. There is a lot to be proud of.

But despite all of that, we couldn't find the product-market fit needed to build a sustainable business around this vision within the time we had.

As a founder, I've always bet the house on the next customer, the next feature or the next launch to change the trajectory of the company. Until even just last weeks, when we announced self-serve Workspace Lite. If we were ever going to close doors, then we never wanted to look back and think "what if".

In hindsight, we could obviously have made different decisions - e.g., surrounding data, or going more vertical with clients and their workflows. But short-term monetization was not something I was prioritizing over where I thought the industry was heading. Ultimately, I wanted us to stand for something.

In the last phase of the company, I explored many paths to give OpenBB a better home. We spoke with larger companies that shared parts of our vision and tried to find a home where the products, and ideally the team behind them, could continue to grow. Ultimately, we weren't able to make that happen.

I left London with my wife to build OpenBB and dedicated almost six years of my life to it. So did the team. We built at the intersection of finance, AI, open source and software infrastructure, often working on problems before they became obvious to the broader market.

Before MCP existed, we had created our own API protocol so agents could interact with the data and analytics widgets in the workspace. In 2023, we built askobb, which let anyone ask investment research questions in natural language that required joining multiple different datasets together.

What this team created deserves to continue existing.

More importantly, I still believe the original vision is inevitable. The future of financial software is not a single platform every firm is forced to use. It is thousands of firms building environments that reflect how they actually work - their own data, internal systems, investment processes, risk models and compliance requirements. Increasingly, their own APIs, MCP servers, models and AI agents too.

If that future is coming, then the technology we built shouldn't disappear simply because we weren't able to commercialize it successfully.

It should become available to everyone.

Today, with the support of the team and OSS Capital, we are committing to releasing the entire OpenBB product suite under a permissive license. This includes OpenBB Workspace, Open Data Platform, OpenBB Copilot and the OpenBB Excel Add-in.

These products represent over 5 years of engineering, millions of dollars invested in R&D and thousands of decisions, experiments and iterations with users. They will become a foundation that individuals, startups, data providers and financial institutions can freely use, modify and build on top of.

We will share more details about the order and timing of each release as we complete that work. In parallel, we will determine the right long-term structure to steward the projects, support contributors and preserve what made OpenBB special in the first place. Existing customers and users of the hosted products will hear from us directly about timelines.

For the partners who built applications for the OpenBB ecosystem, I hope this decision makes your products even more valuable. You already did the work of turning your datasets and analytics into applications that users can interact with. Now, those applications will be able to run inside infrastructure that firms can fully own, extend and customize, while combining them with data and tools from other providers across the ecosystem.

The same applies to the broader community. Developers will be able to use the entire OpenBB stack as a starting point rather than rebuilding the same infrastructure from scratch. Firms will be able to deploy it, adapt it to their requirements and connect it to the systems where their differentiated knowledge already lives.

Over the years, many talented people helped make OpenBB what it is today - employees, contributors, partners. Every one of them left a mark on the product.

But I want to recognize the people who carried OpenBB to the very end. Through the uncertainty and the final stretch, they kept building. They are engineers, product builders, designers and operators who have worked across financial data, AI, developer infrastructure and open source. In alphabetical order, they are:

  • Andrew Kenreich, Head of Product Engineering - LinkedIn
  • Darren Lee, Software Engineer - GitHub, LinkedIn
  • Ihsan Saracgil, CPO - LinkedIn
  • José Donato, Software Engineer - LinkedIn, X, GitHub, Website
  • Juan Alfonso, Software Engineer - GitHub, LinkedIn
  • Minh Hoang, Head of Product - LinkedIn, GitHub
  • Ogonna Nnamani, DevOps - LinkedIn, Medium
  • Rita Figueiredo, Head of Marketing - LinkedIn, Website
  • Rita Soares, Head of Design - LinkedIn, Website
  • Theodore Aptekarev, CTO - LinkedIn, GitHub

To our customers: thank you for trusting a small team with such an ambitious vision.

To our partners: thank you for building alongside us and helping create a more open financial data ecosystem. I hope the next chapter gives you even more freedom to serve your users.

To our investors: thank you for believing in us, including when OpenBB was little more than an idea being built from my living room in London. In particular, I want to thank OSS Capital and Joseph Jacks for supporting this decision and enabling the technology to live beyond the company. Two people I want to name separately: Justin Hoffman and Larry Augustin - working with both of you made me a better founder, but more importantly, a better person.

To every contributor who opened a pull request, reported a bug, wrote documentation, answered a question in Discord, built an integration or simply told someone else about OpenBB: thank you. OpenBB would not have been possible without you.

Finally, to every person who spent part of their career building OpenBB: thank you. We pushed the industry forward and proved that world-class financial infrastructure can be built in the open. The commercial outcome doesn't change the quality of the work.

OpenBB didn't become the company I imagined when I started this journey. But the mission was always larger than the company, and I still believe the ideas behind it are right.

If, ten years from now, firms around the world are using OpenBB as the foundation for software they truly own - connecting their own data, building their own workflows and deploying their own AI agents - then what we built will have achieved something that lasts far beyond us; which was my goal all along: have an impact.

Thank you for one hell of a ride.
