Instead of Gantry
Gantry alternatives
Gantry is a free, Apache 2.0 open-source internal developer platform for teams that need a service catalog, self-service runbooks, GitOps configuration and plugins without maintaining a separate platform team. It runs as one Go binary with embedded SQLite, supports Linux, macOS, Windows, web and self-hosting, and includes Kubernetes, GitHub and ArgoCD integrations. Catalog entries cover services, APIs, teams, infrastructure and environments, with ownership and dependency relationships. YAML definitions support review, diffing and rollback, while SQLite FTS5 provides search without Elasticsearch.

Readers may still seek alternatives because Gantry is self-hosted, in active development and approaching its first stable release, with APIs and schemas that may change. Its published integrations are narrower than some platforms, and its free model may not provide managed infrastructure or specialized governance. When switching, weigh hosted versus self-managed deployment, the cloud and Kubernetes environments you need, catalog and documentation depth, workflow automation, observability, security controls, integration breadth and pricing. Also consider whether you want a focused Go-based platform or a broader portal and delivery system.
