Flyte pricing guide details
Pricing Overview
Flyte is fully open-source under the Apache 2.0 license with over 80 million downloads. There is no license fee to download, deploy, or run Flyte in production. The project is maintained by the Linux Foundation and will remain free to use indefinitely.
For teams that want managed infrastructure, Union.ai offers a commercial managed platform built on Flyte. Union.ai provides two paid tiers: the Team plan at $950/month (which includes a $950 usage credit) and an Enterprise plan with custom pricing, volume discounts, and dedicated support. This dual model gives organizations a clear path from self-hosted open-source to fully managed without changing their workflow code.

| Plan | Price | Compute Included | Key Features | Limits |
|---|---|---|---|---|
| Flyte (self-hosted) | Free / Open Source | None (bring your own infra) | Full orchestrator: workflows, tasks, type-safe data passing, versioning, Kubernetes-native execution, web console | Unlimited users, unlimited workflows |
| Union.ai Team | $950/month | $950 usage credit included | Managed Flyte, GPU scheduling, multi-tenant isolation, 30-day data retention, usage dashboard | Up to 1,000 concurrent actions, 30-day retention |
| Union.ai Enterprise | Custom pricing | Custom allocation | Everything in Team plus multi-cluster, 1-year data retention, volume discounts, dedicated support, SSO, RBAC | Custom limits, SLA-backed |
The Team plan costs $950 per month plus usage and applies a $950 monthly credit toward that usage. Once you exceed the credit, compute is billed at the rates below.
Hidden Costs and Considerations
Usage on the Team plan is billed for actions and action-allocated resources used by workflows, rather than idle capacity.
- GPU compute: T4 starts at $0.12/hr, H200 at $1.20/hr, and B200 at $1.20/hr, lower at higher monthly volume.
- CPU and memory: CPU starts at $0.0288 per vCPU-hour and memory at $0.0040 per GB-hour on the Team plan.
- Monthly plan and usage: The Team plan is $950/mo + usage, with $950 credited to monthly usage.
- Data retention: The Team plan includes 30-day data retention; Enterprise lists custom retention options and a one-year retention period in the plan comparison.
- Enterprise rates: The published pricing lists Enterprise as Custom, with significant volume discounts and custom rates for usage.
Cost Estimates by Team Size
Solo ML engineer or small research team (1-3 people): Self-hosted Flyte on a small Kubernetes cluster carries no licence fee, only infrastructure costs. Union.ai Team at $950/month with the included credit covers light GPU workloads. For teams running fewer than 6 hours/day of GPU tasks on T4g instances, the credit covers the full compute bill.
Mid-size ML team (5-10 engineers): Union.ai Team at $950/month (a monthly minimum credited to usage), plus any usage above that depending on GPU hours. A team running 4 H200 GPUs for 4 hours daily uses about 480 GPU-hours a month, which at $1.20/hr stays within the $950 monthly minimum that is credited to usage. Self-hosting at this scale requires Kubernetes infrastructure plus dedicated platform engineering time.
Enterprise ML platform (20+ engineers): Union.ai Enterprise with custom pricing and volume discounts is the practical choice. At this scale, self-hosting Flyte demands a full-time platform team and its own infrastructure budget. Enterprise features like multi-cluster deployment, 1-year data retention, and SSO become necessary rather than optional.
How Flyte Pricing Compares
Flyte competes primarily with other open-source ML workflow orchestrators. MLflow and Kubeflow are both free and open source, with no first-party managed commercial offering at a comparable price point. Metaflow, also Apache 2.0 licensed, is free to self-host.
Weights & Biases takes a different approach: a free tier for individuals, a Pro plan that starts at $60/month for up to 10 model seats, and Enterprise pricing on request. W&B Pro costs less than Union.ai Team, but without the workflow orchestration capabilities that Flyte provides.
Amazon SageMaker uses pure usage-based pricing with no fixed monthly fee, but costs scale rapidly with compute and storage. SageMaker and Flyte serve overlapping but distinct use cases: SageMaker is a full ML platform, while Flyte focuses on workflow orchestration and reproducibility.
Union.ai's $950/month Team plan is positioned above the free open-source alternatives but below full-platform commercial tools. The $950 monthly usage credit can cover up to $950 of eligible usage, but the Team subscription remains $950 per month plus usage, which is a compelling entry point for teams ready to move beyond self-hosted Flyte without committing to enterprise contracts.
