Built on first principles, 3forge delivers

4 pillars of financial application development

Live Data

A single access point that intersects live and resting datasets from feeds, warehouses, and legacy infrastructures, protected by entitlements, and augmented with complex event processing logic.

Learn more

Live User Interfaces

Build and edit the UI directly in the app with drag-and-drop elements, dividers, tabs, multi-monitor windows, user preferences built-in, and reports to emails, Excel, and PDF.

Learn more

Live Scripting

Combining Java, Python, SQL, and string templates, the 3forge scripting language lets you build and debug reusable business logic from the data model to the shell tool, and embed directly into visuals.

Live Workbench

Evaluate and test business logic, track usage of data and GUIs, and explore the datasets underpinning visualizations directly in the application.

Discover App Engines

App engines like 3forge are extendable software products with a built-in workbench and industry-specific feature-set for quickly planning, building, and operating business applications. From e-commerce and government to manufacturing and video games, App Engines have become the logical option to fast-track the delivery of high-performance applications at optimal quality and minimal cost.

Primary Goal Efficiency

Where does your team spend the most engineering time today: business logic or platform plumbing?

If a meaningful share of effort goes into data ingestion, state management, entitlement checks, monitoring, or deployment mechanics, that's a signal the team is rebuilding infrastructure rather than differentiating logic. Years of targeted research & development in the 3forge Application Engine have led to highly scalable components for virtually every aspect needed to build financial software, and that code has been running in production for years at some of the largest financial institutions in the world.

Why 3forge

The Application Engine
specifically built
for financial workflows

Most enterprise development languages like Java, .NET, C++, or Python were designed as general-purpose tools. They are powerful, but they are not purpose-built for financial workflows. As a result, engineering teams spend significant time adapting generic constructs to model markets, risk, time, and entitlements.

Financial institutions benefit from a development approach designed specifically around financial data, event-driven logic, and regulatory constraints.

3forge provides an application engine purpose-built for financial institutions, where the core primitives reflect how finance actually operates. Time-series and reference data, real-time event processing, entitlements, auditability, and deterministic behavior are native, not bolted on. Developers work within a tightly integrated environment that spans data access, business logic, and visualization, allowing them to express financial workflows directly rather than assembling them from generic frameworks.

The result is faster delivery, fewer architectural workarounds, and production systems that are easier to reason about, govern, and evolve.
