Gantry vs Nullstone

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.

Nullstone is a developer platform for launching and managing applications on cloud providers such as AWS. It can run workloads as containers, serverless apps, static sites, or applications on servers. Preview environments can be created from a pull request or branch and removed after review or testing. Teams provision infrastructure with Terraform modules they can fork, customize, or create from scratch. Nullstone launches infrastructure in customers’ cloud accounts and says it does not access their data; secrets remain in that account in a vault such as AWS Secrets Manager. Its security information lists SOC 2 Type II certification and role-based access controls. Listed integrations include Datadog, NewRelic, SumoLogic, CircleCI, Jenkins, and GitHub Actions. The open-source CLI supports deployments, infrastructure provisioning, data retrieval, and module management on macOS, Windows, and Linux. The Individual plan is free at free; Startup costs $50 a month and includes two users, two environments, and 30 deploys per week. The SaaS service is hosted only and cannot be independently run or installed by customers.
