Build, Customize, and Scale on an Open Platform

Finmars gives developers the freedom to self-host, extend functionality with APIs, and contribute to an open-source ecosystem.
Whether you’re prototyping fintech solutions or deploying production-ready apps, our platform adapts to your workflow.

Core Capabilities for Builders

Move from raw data to actionable insights. Finmars enriches portfolios with context — from strategy tags to performance drivers — so you can quickly identify what’s working, where risks lie, and how to optimize allocations.

Every part of Finmars is designed to connect. Our API-first approach means you can integrate external systems, bring in new data sources, or build custom modules that expand the platform’s functionality. For developers, it’s not just a toolkit — it’s a foundation to create something entirely new.

Turn ideas into working solutions in days, not months. Finmars makes it simple to spin up a local environment, test new workflows, and experiment with different data configurations. Once you’re ready, moving from prototype to production is seamless, with no need to start over.

Your work doesn’t end with a prototype. With Finmars, developers can package their add-ons and publish them to the Marketplace — making it easy to share innovations, collaborate with peers, and even monetize the tools you build.

Turn Code Into Solutions

No heavy setup, no vendor lock-in. Finmars lets you self-host, extend with APIs, and prototype quickly —
so you can focus on building, not managing infrastructure.
