Union.ai · Pricing Plans

Unionai Plans Pricing

Union.ai is the commercial platform built on the open-source Flyte project (Apache-2.0, free to self-host). Union itself does not sell raw compute; it bills usage-based pricing for the orchestration plus the action-allocated CPU / Memory / GPU resources each workflow uses, metered per second, never for idle capacity. The Serverless / Team plan is pay-as-you-go with a free trial credit; Enterprise (including BYOC and self-hosted) is sales-led with custom, negotiated pricing. Specific rates change frequently and many enterprise terms are not published, so this artifact is not reconciled.

Unionai Plans Pricing is the machine-readable pricing-plan profile for Union.ai on the APIs.io network, conforming to the API Commons Plans specification.

It defines 3 plans, covering free, usage, and enterprise tiers, with named plans including Flyte (Open Source), Serverless / Team (Pay-as-you-go), Enterprise / BYOC.

Tagged areas include AI, ML, Orchestration, Workflows, and Serverless.
