Introduction
As organizations adopt microservices, cloud-native architectures, and DevOps practices, developers often face increasing complexity. A single application may involve multiple repositories, Kubernetes clusters, CI/CD pipelines, cloud services, monitoring tools, and documentation systems.
While these tools improve development capabilities, they can also create fragmented developer experiences. Developers spend valuable time searching for documentation, locating service ownership information, managing deployments, and navigating multiple platforms.
Internal Developer Platforms (IDPs) address this challenge by providing a centralized self-service experience for engineering teams. One of the most popular tools for building an IDP is Backstage.
Originally developed by Spotify, Backstage has become a widely adopted open-source platform for creating developer portals and streamlining software development workflows.
In this article, you'll learn what Backstage is, how Internal Developer Platforms work, and how to build an effective developer platform using Backstage.
What Is an Internal Developer Platform?
An Internal Developer Platform is a collection of tools, workflows, and services that provide developers with a unified interface for building, deploying, and managing applications.
The goal is to reduce operational complexity and improve developer productivity.
A typical Internal Developer Platform provides:
Instead of interacting with numerous disconnected systems, developers use a single platform.
What Is Backstage?
Backstage is an open-source platform for building Internal Developer Portals.
It provides a central location where developers can:
Discover services
View documentation
Manage software components
Access deployment pipelines
Track ownership information
Integrate engineering tools
Backstage follows a plugin-based architecture, allowing organizations to customize the platform according to their requirements.
Why Organizations Adopt Backstage
As engineering organizations grow, common challenges begin to appear.
Examples include:
Hundreds of repositories
Unclear service ownership
Scattered documentation
Inconsistent onboarding processes
Multiple deployment tools
Without a central platform, developers spend significant time locating information.
Backstage addresses these issues by creating a unified developer experience.
Benefits include:
Faster onboarding
Improved developer productivity
Better service visibility
Standardized workflows
Reduced operational overhead
High-Level Backstage Architecture
A typical Backstage architecture looks like this:
Developers
↓
Backstage Portal
↓
Service Catalog
Documentation
CI/CD Systems
Cloud Platforms
Monitoring Tools
Backstage acts as the central entry point for engineering teams.
Developers access information and workflows through a single interface.
Core Components of Backstage
Software Catalog
The Software Catalog is one of the most important Backstage features.
It provides a centralized inventory of services, applications, libraries, and infrastructure components.
Example:
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
name: order-service
spec:
type: service
owner: payments-team
The catalog enables developers to quickly answer questions such as:
Who owns this service?
Where is the source code?
What documentation exists?
What dependencies are involved?
TechDocs
Documentation often becomes scattered across repositories and wikis.
Backstage TechDocs centralizes technical documentation.
Example structure:
Order Service
├── Overview
├── Architecture
├── API Reference
└── Deployment Guide
Documentation becomes easier to discover and maintain.
Scaffolder
The Scaffolder automates project creation.
Instead of manually configuring repositories and pipelines, developers can use templates.
Example workflow:

Template Selection
↓
Repository Creation
↓
CI/CD Setup
↓
Deployment Ready
This helps enforce engineering standards across teams.
Plugins
Backstage supports a rich plugin ecosystem.
Popular integrations include:
GitHub
GitLab
Jenkins
Kubernetes
Argo CD
PagerDuty
Datadog
Prometheus
Plugins allow organizations to bring existing tools into a single platform.
Setting Up a Backstage Instance
Create a new Backstage application.
npx @backstage/create-app@latest
Navigate into the project.
cd my-backstage-app
Start the application.
yarn dev
The portal becomes available locally for development and customization.
From there, teams can begin configuring catalogs, documentation, and integrations.
Building a Service Catalog
One of the first tasks when implementing Backstage is registering services.
Example component definition:
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
name: customer-api
spec:
type: service
lifecycle: production
owner: customer-team
After registration, developers can search and discover services through the portal.
This creates visibility across the engineering organization.
Integrating Kubernetes
Many organizations use Backstage to simplify Kubernetes operations.
Architecture:
Backstage
↓
Kubernetes Cluster
↓
Applications
Developers can:
View deployments
Check pod health
Access service status
Monitor workloads
This reduces the need to switch between multiple operational tools.
Real-World Example
Imagine an organization with fifty microservices.
Without Backstage:
Git Repositories
Wiki Pages
CI/CD Dashboards
Monitoring Tools
Cloud Consoles
Developers must navigate multiple systems to perform basic tasks.
With Backstage:
Backstage Portal
↓
Everything Accessible
The platform becomes the central hub for engineering workflows.
This significantly improves developer experience and productivity.
Best Practices
When building an Internal Developer Platform with Backstage, consider the following recommendations.
Start with the Service Catalog
Create a complete inventory of services before adding advanced functionality.
Standardize Templates
Use Scaffolder templates to enforce architecture and deployment standards.
Centralize Documentation
Adopt TechDocs to improve discoverability and consistency.
Integrate Existing Tools
Avoid replacing proven tools unnecessarily.
Instead, connect them through Backstage plugins.
Define Ownership Clearly
Every service should have an assigned owner or team.
This improves accountability and incident response.
Measure Developer Experience
Track metrics such as:
These measurements help evaluate platform success.
Common Challenges
Organizations implementing Backstage may encounter challenges such as:
Keeping service metadata updated
Managing plugin complexity
Encouraging adoption across teams
Maintaining documentation quality
Scaling platform governance
A phased rollout strategy often produces the best results.
Start with core capabilities and expand gradually.
Conclusion
Internal Developer Platforms are becoming an essential part of modern software engineering organizations. As systems grow more complex, developers need a unified way to discover services, access documentation, manage deployments, and interact with infrastructure.
Backstage provides a powerful foundation for building these platforms. Through features such as the Software Catalog, TechDocs, Scaffolder, and plugin ecosystem, organizations can create a centralized developer experience that improves productivity and reduces operational friction.
Whether you're managing a handful of services or hundreds of microservices across multiple teams, Backstage can help establish a scalable and efficient Internal Developer Platform that empowers developers to focus on building software rather than navigating tooling complexity.
