Gantry vs OpenChoreo

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.

OpenChoreo is a modular, open-source developer platform for Kubernetes that combines developer abstractions, a Backstage-powered portal, CI/CD, GitOps, and observability. Programmable abstractions and golden paths let developers build, deploy, and operate applications without directly managing Kubernetes complexity. Its multi-plane architecture separates control, runtime data, workflows, and observability, and supports deployment across multiple clusters and cloud providers. It can be installed on Kubernetes in cloud or on-premises environments, including hybrid and edge infrastructure. Git repositories can serve as the source of truth for platform configuration and application deployments. CI can use Argo Workflows or external pipelines such as Jenkins and GitHub Actions through the API; Flux CD is the default GitOps module, with Argo CD available as a community module. Observability covers logs, metrics, traces, and alerts mapped to the application model. The platform also includes SRE and FinOps agents and MCP servers and skills for AI-assisted delivery and operations within platform guardrails. Role-based authorization and tenancy boundaries support governed self-service. The project points users to CNCF Slack, GitHub Discussions, and issue reporting for support.
