Pricing
The engine, the CLI, the SDK, the agent adapter and the whole web UI are open source under Apache-2.0, free to run on as many pipelines and servers as you like. Organisations that need identity, governance, connectors and support take the commercial edition.

The UI is in the open-source core on purpose: it is what makes Millstream convincing to the people who run it and to the customers they run it for. The commercial edition is for the questions that come with scale: who may see this inbox, who may accept a proposal, and what happened, for the auditor.
Commercial terms
Commercial terms follow from the deployment: where it runs, how many pipelines it carries and the support it needs. Write to contact@monolithiclab.fr with what you run and where.
Early access
The five milestones of the platform are built and tested; the first open-source release is the next one. Teams with a real pipeline to run, code, agents and people together, can start before it, with direct access to the engineers who built it.
Write to contact@monolithiclab.fr with what your pipeline does, its volume and where it would run.
Help building it
Millstream is made by Monolithic Lab, a studio that also builds automation for its clients as forward-deployed engineers. If you would rather have the first pipeline built with you, on your infrastructure, the same address reaches the team.
