Why the Future of API Orchestration is Open Source: Meet Fluxnova at apidays Paris

Written by Grizz Griswold | 11/25/25 12:47 PM

In the world of modern software architecture, APIs provide the connectivity, but orchestration provides the logic. Whether you are chaining microservices, managing long-running transactions, or coordinating AI agents, the "glue" that holds your APIs together is becoming just as critical as the endpoints themselves.

This December 11th, at apidays Paris, FINOS (The Fintech Open Source Foundation) is bringing a new, production-grade answer to the orchestration challenge: Fluxnova.

WHAT IS FLUXNOVA?

Fluxnova is a new open-source workflow and process automation platform hosted by FINOS. Born from a collaboration between Fidelity Investments, NatWest Group, Deutsche Bank, Capital One, and BMO, it is a fork of the battle-tested Camunda 7 Community Edition, designed to ensure the financial services industry has a high-performance, vendor-neutral orchestration engine.

Why API Developers Should Care

If you are building APIs, you are likely dealing with state, timeouts, retries, and complex decision logic. Here is why Fluxnova belongs in your stack:

Stateful Orchestration for Stateless APIs: Fluxnova manages the state of long-running processes so your APIs don't have to.
The "Agentic AI" Layer: As we move from generative AI to agentic AI, you need a control plane to manage how AI agents interact with your core systems. Fluxnova provides the guardrails and audit trails necessary to put AI agents into production safely.
Freedom from Lock-in: As a project under the Linux Foundation umbrella, Fluxnova guarantees that your orchestration layer remains open, governed by the community, and free from sudden licensing shifts.
