Conductor: sovereignty score and 8 European alternatives

Conductor is an open-source workflow engine for orchestrating microservices and AI agents. Workflows are versioned, machine-readable graphs, while workers written in languages such as Java, Python, JavaScript, Go and C# run the business logic. Each step is persisted, so workflows can recover from crashes and restarts, with configurable retries and timeouts. Features include branching, loops, parallel execution, sub-workflows, human approval steps and LLM tasks, plus a built-in user interface. You can run Conductor through the CLI, with Docker or from source, using Redis, PostgreSQL or MySQL for persistence.

Conductor was developed at Netflix and released as open source under the Apache 2.0 licence. Orkes, a US company founded by Conductor's creators, is the primary maintainer and also offers a commercial SaaS version, Orkes Conductor, as well as a free hosted Developer Edition. If you self-host, you decide where the data resides. The sources consulted do not name hosting regions for the Orkes services.

Why digital sovereignty matters with Conductor

Conductor is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Conductor hosts data outside the EU (self-host, multi-cloud). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Conductor is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Conductor together with your other vendors and gives a total score, a heatmap and the main risk drivers.
