Platform engineering teams keep running into the same problem: they build a portal, wire it up to some infrastructure automation, and within a year the platform starts feeling like another legacy system to maintain. The tools below all aim to solve this, but they don't all start from the same problem.
This article compares four projects people keep asking about: Kratix, KubeVela, KusionStack, and Humanitec. Two of them orchestrate platforms in the fuller sense, meaning they coordinate infrastructure, policies, and workflows as a system. The other two are really solving a narrower problem, application deployment, and one of them does this despite using "orchestrator" in its own name. Knowing which is which will save you a few months of evaluation.
What platform orchestration actually means
Platform orchestration sits in the middle of three layers of a platform: application choreography (how developers code, ship, and run), platform orchestration (how platform components, policies, and workflows are managed), and infrastructure orchestration (how compute, storage, and networking get provisioned). Many tools try to stretch beyond a single layer, and that breadth reduces their overall impact.
Two common failure modes are worth identifying.
A pure application deployment tool is focused on a single instance. It can get you fast day-one self-service and even day-two operations for that specific application. However, platform-layer outcomes such as upgrading a shared dependency across a hundred services, changing a policy fleet-wide, and retiring a deprecated resource type tend to fall back on scripts and tickets. A genuine platform orchestrator treats those lifecycle problems as first-class, not an afterthought bolted onto a CI pipeline.
A pure infrastructure orchestrator speaks 3rd party API languages seamlessly, but business and user languages are not the same. Automating cloud, SaaS, and hardware resources is simple, but adding approval workflows, audit checks, and security scans requires stitching infrastructure tools together with another solution, such as a CI pipeline.
While failure modes differ, demand for a tool that lets platform teams offer capabilities with a clear API, diverse automation on demand, and lifecycle management shows the value of that middle platform layer. The key is realising that portals and CI/CD pipelines alone are a band-aid, not a solution.
Comparison at a glance
Tool | Primary focus | Deployment model | Kubernetes-native? | Best for |
Kratix | Platform orchestration (any resource type: infra, apps, data, AI agents) | Promise-based, extensible framework | Yes, but extensible beyond it | Teams building a full IDP across heterogeneous resources |
KubeVela | Application delivery | OAM-based workflow engine | Yes | Teams standardising app deployment across hybrid/multi-cloud |
KusionStack | Platform/infra orchestration | Intent-driven config and workflow model | Yes, extensible to Terraform and other IaC | Developers bridging application code and infrastructure |
Humanitec | Application orchestration (despite the name) | Score-based workload spec, graph-based orchestrator | No | Teams standardising deployment and environment management for application workloads |
KubeVela: application delivery built on the Open Application Model
KubeVela is a CNCF incubating project built around the Open Application Model (OAM), a specification for describing application components, traits, and workflows in a way that's separated from the underlying infrastructure. Its "render, orchestrate, deploy" model lets platform teams define reusable building blocks (components, traits, policies) that developers then compose without needing to understand the Kubernetes details underneath.
KubeVela is squarely an application delivery engine. It orchestrates the deployment and operation of application components across hybrid and multi-cloud environments, and it does this well, particularly for organisations already comfortable with Kubernetes and CUE. Where it's less of a fit is anything outside the application layer: it's not designed to be the system that also manages your platform's policies, infrastructure lifecycle, or non-application resources.
KusionStack: intent-driven orchestration across roles
KusionStack, a CNCF Sandbox project originally developed at Alibaba, positions itself explicitly as a "Declarative Intent Driven Platform Orchestrator." Its core idea is to capture intent from different roles (developers, platform engineers, operators) and reconcile those intents against different infrastructure targets, rather than assuming a single source of configuration truth.
In practice, this means platform engineers define reusable Kusion Modules, developers consume them without needing to know what's underneath, and the system extends beyond Kubernetes to Terraform and other infrastructure targets. That combination makes KusionStack a genuine platform orchestrator in its own right, not just an application delivery tool: it's trying to unify application and infrastructure intent into one workflow, not just standardise how applications get deployed. It's an earlier-stage project than KubeVela in terms of CNCF maturity level, worth factoring in if project maturity is part of your evaluation criteria.
Humanitec: an application orchestrator wearing a platform orchestrator's name
Humanitec calls its product the "Platform Orchestrator," but the label outstretches the product's actual focus. The Score workload specification captures application architecture and infrastructure dependencies declaratively, and the Orchestrator dynamically generates and applies configuration for every deployment, including environment management, resource provisioning, and RBAC. However, Humanitec's model is built around the workload, meaning it's oriented around deploying and operating single applications rather than managing platform capabilities across the lifecycle as an independent concern.
That workload-centric approach doesn't meet the fuller definition of platform orchestration. A genuine platform orchestrator needs to treat the dependencies that support applications, such as shared data resources, AI agent fleets, and cross-team policy rollouts, as first-class objects rather than deployment-time config. With Humanitec, managing the lifecycle of these resources will feel like it's being bent to fit rather than built for it.
Kratix and SKE: orchestration for the whole platform, not just the app
Kratix is Syntasso's open source platform orchestration framework, with Syntasso Kratix Enterprise (SKE) offering additional product features, faster onboarding, and enterprise support. Where most tools in this space stretch into a second layer (usually application delivery, sometimes infrastructure composition), Kratix is deliberately unopinionated about what it orchestrates both above and below the platform layer. A Kratix Promise can package up anything a platform team wants to offer as a service: a database, a Kubernetes cluster, a CI pipeline, a compliance policy, or increasingly, an AI agent.
That extensibility is the point. Platform teams don't get to choose a stable, fixed scope for what "the platform" needs to offer. New requirements show up constantly, and rebuilding your orchestration layer every time is expensive. Kratix lets teams add new capabilities as Promises without re-architecting the platform orchestration underneath, which is why it tends to show up in enterprise environments dealing with a genuinely widespread range of resource types rather than a single application deployment pattern.
How to choose a platform orchestrator
Start with what you actually need to orchestrate. If the honest answer is "get applications deployed consistently across environments," KubeVela or Humanitec may get you there faster. If the answer includes infrastructure, data resources, or anything outside the application boundary, and especially if you expect that scope to keep growing, KusionStack and Kratix are built for that reality rather than adapted to it.
A useful gut check: ask how many people need to get involved in a simple and safe (but urgent) security patch change? Tools optimised for application delivery tend to make day-one provisioning easy and leave day-two ownership unresolved and hard to manage. Tools built as genuine platform orchestrators build clear responsibility lines from the start and treat day two as the actual job.

FAQ
No, and that's really the point. KubeVela is an excellent application delivery engine built on OAM, while Kratix is a platform orchestrator designed to manage any resource type, not just applications. They solve different problems and can be used together: KubeVela for app delivery workflows, Kratix for the broader platform layer.
No. KusionStack extends beyond Terraform and Kubernetes as orchestration targets, but it sits above infrastructure-as-code tools, coordinating intent across roles rather than replacing IaC outright.
Q. Is Humanitec a platform orchestrator or an application orchestrator?
Humanitec brands itself as a platform orchestrator, but its architecture centres on deploying and managing application workloads and their infrastructure dependencies. It's best understood as an application-focused orchestrator with strong environment and configuration management, rather than a tool that orchestrates the platform's full lifecycle independent of any single application.
Infrastructure orchestration configures lower-level resources like compute, storage, and networking through API automation. Platform orchestration sits a layer above that, managing the platform's own components, policies, and workflows so teams can evolve the platform without every change rippling back down to raw infrastructure config.
You can, but weigh it carefully: platform orchestration logic isn't where your product differentiates, and the real cost isn't getting a first version working; it's maintaining it for years as new environments, governance requirements, and platform capabilities arrive. That maintenance work tends to land on your most senior platform engineers, the people best placed to build what actually sets you apart. See Syntasso's comparison of building your own platform orchestrator versus Syntasso Kratix Enterprise (SKE) for a fuller breakdown of the trade-offs.
