Gantry vs WSO2 Developer Platform

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, identified as the WSO2 Developer Platform, is a Kubernetes-native internal developer platform for platform engineers. It offers reusable abstractions, a Backstage-powered developer portal, built-in CI/CD, GitOps workflows, observability, and policy enforcement, while keeping Kubernetes as the system of record. The platform runs on any Kubernetes environment, including public cloud, hybrid or multi-cloud, and on-premises deployments. WSO2’s managed cloud option is available on AWS, Azure, and GCP. On-premises deployment supports secure, air-gapped private data centers and keeps data within the customer’s perimeter. Platform engineers retain control of network policies, access controls, and data residency. OpenChoreo integrates with Backstage and is validated for SUSE Rancher Prime and AWS Marketplace. Its open-source foundation includes GitHub issues, documentation, and a Slack community. Enterprise support lists round-the-clock incident support, guaranteed SLAs, security monitoring, guided onboarding, and direct engineering access. Quick start requires Docker and at least 4 GB RAM with 2 CPUs, or 8 GB RAM with 4 CPUs when WorkflowPlane is installed. CI/CD and observability can be enabled during installation.
