Backstage

Backstage is an open platform for building developer portals and cataloging software components, services, and infrastructure within organizations. It provides a unified developer experience by combining service discovery, documentation, observability, and software templates into a single interface used by engineering teams at scale. Backstage originated in the technology practices of prominent companies and has been adopted broadly across enterprises, cloud providers, and platform engineering organizations.

Overview

Backstage presents a centralized catalog and plugin-driven interface that aggregates metadata about software artifacts, teams, and infrastructure. It integrates with systems such as GitHub, GitLab, Bitbucket, Jenkins, CircleCI, Travis CI, Kubernetes, Terraform, AWS, Microsoft Azure, Google Cloud Platform, Datadog, Prometheus, Grafana, PagerDuty, Slack, JIRA, Confluence, Sentry, New Relic, Elastic Stack, Azure DevOps, HashiCorp Vault, Consul, Istio, Linkerd, Argo CD, Spinnaker, Helm to present runtime, deployment, and operational data alongside code and documentation. The platform emphasizes extensibility via a plugin architecture and uses standardized descriptors to represent components, repositories, APIs, and resources for discoverability and governance.

History

Backstage was open-sourced by Spotify after being developed internally to standardize platform tooling across many teams. Early public milestones included community contributions from organizations such as Amazon, Microsoft, VMware, Red Hat, Intel, IBM, Confluent, Databricks, and Netflix. The project gained traction through developer conferences and code repositories hosted on GitHub and collaborations with foundations and standard bodies. Over successive releases the community introduced integrations for CI/CD systems like Jenkins and CircleCI, observability vendors like Datadog and Grafana Labs, and cloud platforms including AWS, Google Cloud Platform, and Microsoft Azure.

Functions and Features

Backstage offers a catalog model, documentation hubs, software templates, and a plugin ecosystem. The catalog indexes entities such as services, libraries, APIs, websites, data pipelines, and domains, linking to code in GitHub, GitLab, and Bitbucket repositories and to CI pipelines in Jenkins and CircleCI. The software templates system, influenced by patterns from Yeoman and Cookiecutter, enables standardized scaffolding for microservices, libraries, and infrastructure as code using Terraform modules, Helm charts, and kustomize overlays. Documentation features connect to systems like Confluence and static site generators such as Docusaurus and Gatsby. Plugins surface telemetry from Prometheus, Grafana, New Relic, and Datadog while linking incident context from PagerDuty and task tracking in JIRA.

Architecture and Technology

Backstage is built primarily with Node.js and React and is written in TypeScript, offering a frontend app and a backend service. The architecture separates a static frontend application from backend plugins and data sources, enabling deployment patterns on Kubernetes using operators, Helm charts, and ingress controllers. The backend connects to catalogs, CI systems, artifact registries like Docker Hub and Harbor, and secret stores such as HashiCorp Vault. Authentication and authorization integrate with identity providers like Okta, Auth0, Azure Active Directory, and Google Identity Platform and can leverage OAuth 2.0, OpenID Connect, and SAML flows. The project adopts modern web tooling including Webpack, Babel, and testing frameworks like Jest and Cypress.

Use Cases and Integrations

Organizations use Backstage for service discovery, developer onboarding, compliance, internal marketplaces, and platform standardization. Platform engineering teams integrate Backstage with CI/CD pipelines in GitHub Actions, GitLab CI, Jenkins, and Argo CD to expose build statuses and deployment history. Data teams link to pipelines in Apache Airflow and Databricks while security teams surface findings from Snyk, Dependabot, WhiteSource, and SonarQube. Cloud teams connect catalog entities to provisioning via Terraform, deployment via Kubernetes and Helm, and cost insights from AWS Cost Explorer and Google Cloud Billing. Service owners find traces and logs through Jaeger, Zipkin, and Elastic Stack integrations.

Adoption and Community

Backstage has a growing ecosystem of organizations, contributors, and vendors that publish plugins, templates, and hosted offerings. Prominent adopters include Spotify, American Express, Pinterest, Zalando, Goldman Sachs, Stripe, Airbnb, Expedia Group, Squarespace, Shopify, and Uber. The community collaborates on GitHub repositories, participates in meetups and conferences organized by companies and foundations, and contributes to plugin registries and examples. Commercial vendors and consulting firms provide managed Backstage services and professional support, integrating with enterprise identity, logging, and observability stacks.

Security and Governance

Backstage supports governance via catalog policies, role-based access control, and integrations with policy engines such as Open Policy Agent. Secrets and credentials can be sourced from HashiCorp Vault, cloud secret managers in AWS Secrets Manager, Google Secret Manager, and Azure Key Vault. Audit logging and access controls tie into identity providers like Okta and Azure Active Directory, while SSO and federation use SAML and OpenID Connect. Security scanning plugins connect to dependency management tools like Snyk and Dependabot and static analysis platforms like SonarQube to surface vulnerabilities in the developer portal.
