Pneumatic

Pneumatic is free to start with and open source, so you can run and modify it yourself. The Pneumatic workflow management platform automates business processes by pairing people and AI agents on the same tasks, and it assigns work between them based on what each step needs.

A Workflow Template Generator picks up on your specific needs and requirements and builds a starting template, and there is a large library of free templates if you would rather begin from something ready made.

The Self-serve plan gives you unlimited users for a fixed price, which suits growing teams that dislike per-seat billing.

Support on that plan is limited, though.

The Turnkey and Enterprise plans can get expensive.

Pneumatic connects with external systems, but expect some initial setup and configuration, and advanced customization may call for technical knowledge.

Pneumatic makes most sense for teams that want control over how their processes run and have someone comfortable with setup.
