We’re excited to announce that the new Splunk Developer Portal is now live at: dev.splunk.com
This is not just a visual refresh. It is a complete rebuild of the platform, designed to modernize the demveloper experience, remove legacy constraints, and create a strong foundation for future innovation.
Why We Rebuilt the Developer Portal
The previous portal was built on Gatsby, a framework now in maintenance mode with limited long-term support. Over time, this created challenges in keeping the platform aligned with evolving engineering standards and scalability needs.
Rather than continuing incremental updates, we took the opportunity to re-architect the platform on a modern, well-supported stack to better support long-term growth and innovation.
The new portal is built on:
- Next.js 15 for server-side rendering and static generation
- Node.js 22, replacing an older runtime
- React 18 for improved performance and UI capabilities
- TypeScript for full type safety and improved code quality
We also consolidated three separate repositories into a single unified codebase, processed and optimized over 130,000 lines of code, and removed approximately 15,000 lines of redundant or hard-to-maintain logic.
Security, Performance and Reliability Improvements
This rebuild significantly strengthens the platform’s overall security posture by modernizing dependencies and aligning with current best practices.
We also made substantial improvements in reliability and quality:
- Test coverage increased from 23% to approximately 95%
- Introduced unit, functional, and visual regression testing
- Ensured zero downtime during migration
- Maintained SEO rankings through precise redirect strategies
These improvements ensure the platform is stable, resilient, and ready to scale with evolving developer needs.
Improved Developer Experience
The new portal introduces a more consistent and modern user experience:
- Integration of the latest @splunk/react-ui components
- Support for light and dark modes
- Improved documentation structure, navigation, and performance
In addition, the new architecture enables better handling of documentation features such as versioning, search, content reuse, and API references. This makes it easier for developers to discover, understand, and build with Splunk capabilities.
What This Enables Next
This foundation unlocks several exciting opportunities moving forward:
- AI-powered developer experiences, including smarter search and content discovery
- Potential CMS integration to enable technical writers to manage content with real-time previews
- Closer integration with Splunk Cloud Developer Edition (SCDE) and the Splunk Developer Program
These enhancements will help create a more connected and efficient developer ecosystem.
Important Updates for Contributors
With the launch of the new portal:
- All updates must now be made in the new system
- Changes made to the old portal will not be migrated
