About Kosko

Kosko is a tool for writing Kubernetes manifests using JavaScript, with features for reusing variables and functions, splitting manifests into components and environments, and validating them against Kubernetes OpenAPI schema.

How to evaluate Infrastructure as Code

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Kosko. It comes from our Infrastructure as Code (IaC) Platforms buyer guide.

25%

Language & Authoring Model

Declarative DSL (HCL) vs. general-purpose language (TypeScript, Python, Go, C#); readability for reviewers vs. expressive power (loops, conditionals, abstractions); module/component reuse and registry maturity; testing and IDE support; learning curve for the people who will actually write infrastructure

20%

State Management & Drift

Where state is stored, remote-state locking to prevent concurrent-apply corruption, state encryption and secret handling, plan/preview fidelity, drift detection and continuous reconciliation, import of existing resources, and blast-radius controls on apply

20%

Policy-as-Code & Governance

OPA/Rego and Sentinel support, pre-apply guardrails (block non-compliant resources, mandatory tags, region/cost limits), RBAC and SSO/SAML/SCIM, audit logging, approval workflows, and integration with cost-estimation and security scanning in the pipeline

15%

Provider Ecosystem & Portability

Breadth and quality of providers/resource coverage, day-one support for new cloud services, multi-cloud and on-prem reach, third-party SaaS providers, and how locked-in the resulting code is to one vendor or one cloud

10%

Collaboration & Workflow (TACOS)

Run orchestration and queuing, VCS/PR-driven plans, stack dependencies, self-service environments with TTL/ephemeral teardown, drift remediation workflows, and whether you self-host in CI (Atlantis-style) or buy a managed platform

10%

Licensing & Project Health

License (open-source MPL/Apache vs. source-available BUSL vs. proprietary), governance and ownership after recent M&A, release cadence and roadmap, community/foundation backing (CNCF, Linux Foundation), and how easily you could exit or fork

Other Infrastructure as Code Vendors

Related Buyer Guides

Our buyer guides across DevOps & Platform Engineering. Each one compares the main vendors in its category and what buyers weigh up.

AI Code Assistants & Coding Agents

Evaluate GitHub Copilot, Cursor, Claude Code, Amazon Kiro, JetBrains Junie, Sourcegraph, Tabnine, Windsurf/Devin, and others — with enterprise governance and agentic autonomy, not autocomplete acceptance rates, as the deciding criteria.

API Testing & Quality Assurance

Evaluate Postman, SmartBear (ReadyAPI/Pact), Tricentis, Katalon, Parasoft, and the open-source Karate framework — weighing whether tests stay green as your APIs change every week, not whose demo flows best.

Application Performance & Load Testing

Compare Grafana k6, Apache JMeter, Gatling, OpenText LoadRunner, NeoLoad, BlazeMeter, Locust, and Azure Load Testing — and decide whether performance testing lives with your engineers as code or with a separate testing team.
