In their own words
Gantry
Gantry is an open-source internal developer platform for teams that need a service catalog and self-service workflows without dedicated platform engineering staff. Its catalog brings together services, APIs, teams, infrastructure components, and environments, including ownership and dependency relationships. Teams can create executable runbooks and workflows with schema-driven forms for tasks such as deployments and environment provisioning. Catalog entities can be written in YAML and applied with `gantry apply`, supporting version control, review, diffs, and rollback. Search uses SQLite FTS5, so Elasticsearch is not required. Official integrations include Kubernetes, GitHub, and ArgoCD; PagerDuty, Datadog, Grafana, and Flux are planned. Gantry ships as a Go binary with embedded SQLite and no external runtime dependencies. It can be installed from a binary, run through Docker or Docker Compose, or built from source. The documentation describes JWT authentication and requires installers to set an admin password. Gantry is self-hosted, licensed under Apache 2.0, and free. Its documentation says it is in active development and that APIs and schemas may change before its first stable release.
Kratix
Kratix is an open-source framework for building internal developer platforms and coordinating platform capabilities. Its Promises define self-service APIs, embed workflows, and manage resources across a fleet. Teams can encode organisation and department policy or governance in reusable Promises and Workflows, then operate platform resources across clusters as one automated fleet. The maker describes access through portals, APIs, command-line tools, GitOps workflows, MCPs, automation, and AI agents. Kratix is available through an API and as self-hosted software, with installation guidance for Azure Kubernetes Service, Amazon EKS, Google Kubernetes Engine, Red Hat OpenShift, and other Kubernetes environments. The free Kratix Open Source plan costs nothing and includes the core, Promise-writing CLI, Go and Python SDKs, revisions and upgrades, metrics and observability endpoint, Marketplace, and Community Slack support. Paid SKA, SKE, and Integrator plans are billed Contact Us.
