Harness Granted Patent for Hybrid YAML Editor – Redefining CI/CD Configuration

‍

We're thrilled to share some exciting news: Harness has been granted U.S. Patent US20230393818B2 (originally published as US20230393818A1) for our configuration file editor with an intelligent code-based interface and a visual interface.

This patent represents a significant step forward in how engineering teams interact with CI/CD pipelines. It formalizes a new way of managing configurations - one that is both developer-friendly and enterprise-ready - by combining the strengths of code editing with the accessibility of a visual interface.

The Problem: YAML’s Double-Edged Sword

In modern DevOps, YAML is everywhere. Pipelines, infrastructure-as-code, Kubernetes manifests, you name it. YAML provides flexibility and expressiveness for DevOps pipelines, but it comes with drawbacks:

• Steep learning curve for newcomers.
• High error rate from indentation, nesting, and schema mismatches.
• Limited accessibility for non-developer stakeholders.
• Lack of standardization across services and teams.

The result? Developers spend countless hours fixing misconfigurations, chasing down syntax errors, and debugging pipelines that failed for reasons unrelated to their code.

We knew there had to be a better way.

The Invention: Hybrid YAML Editing

The patent covers a hybrid editor that blends the best of two worlds:

1. Code-based editor - for developers who prefer raw YAML, enhanced with autocomplete, inline documentation, and semantic validation.
   
   
2. Visual editor - a graphical interface that allows users to configure pipelines through icons, dropdowns, and drag-and-drop interactions, while still generating valid YAML under the hood.
   
   

What makes this unique is the schema stitching approach:

• Each microservice defines its own configuration schema.
• These are stitched together into a unified schema.
• The editor utilizes this unified schema to provide intelligent suggestions, detect errors, and validate content.

This ensures consistency, prevents invalid configurations, and gives users real-time feedback as they author pipelines.

Strategic Advantages

This isn’t just a UX improvement - it’s a strategic shift with broad implications.

1. Faster Onboarding

New developers no longer need to memorize every YAML field or indentation nuance. Autocomplete and inline hints guide them through configuration, while the visual editor provides an easy starting point. A wall of YAML can be hard to understand; a visual pipeline is easy to grok immediately.

2. Reduced Errors and Failures

Schema-based validation catches misconfigurations before they break builds or deployments. Teams save time, avoid unnecessary rollbacks, and maintain higher confidence in their pipelines.

3. Broader Adoption Across Roles

By offering both a code editor and a visual editor, the tool becomes accessible to a wider audience - developers, DevOps engineers, and even less technical stakeholders like product managers or QA leads who need visibility.

How It Works in Practice

Here’s a simple example:

Let’s say your pipeline YAML requires specifying a container image.

• In raw YAML, you’d type:
  
  

image: ubuntu:20.04

But what if you accidentally typed ubunty:20.04? In a traditional editor, the pipeline might fail later at runtime.

• In our editor, the schema stitching recognizes valid image registries and tags.
  
  
• It suggests ubuntu:20.04 as a valid option.
  
  
• If you mistype, it immediately flags the error, before you hit run.
  
  

Now add the visual editor:

• Instead of writing image: ubuntu:20.04, you pick “Ubuntu” from a dropdown of supported images.
  
  
• The editor still generates the underlying YAML for transparency, but you never risk invalid syntax.
  
  

Multiply this by hundreds of fields, across dozens of microservices, and the value becomes clear.

The Bigger Picture: Why This Matters Now

We’re in a new era of software delivery:

• Microservices mean more schemas, more configurations, more complexity.
  
  
• Platform engineering emphasizes self-service tooling for developers who don’t want to learn every underlying detail.
  
  
• Security and compliance demand consistency and auditability in configuration.
  
  ‍

This patent directly addresses these trends by creating a foundation for intelligent, schema-driven configuration tooling. It allows Harness to:

• Build predictive configuration (e.g., suggesting next steps based on prior patterns).
  
  
• Offer real-time linting and autofix for YAML.
  
  
• Enable cross-service validation that ensures configurations align across the entire delivery pipeline.
  
  

Looking Ahead

With this patent secured, the door is open to innovate further:

• Smarter autocomplete powered by AI.
  
  
• Context-aware suggestions based on past pipelines.
  
  
• Richer visualizations of complex configurations.
  
  
• Automated detection of security misconfigurations.

This isn’t about YAML. DevOps configuration must be intuitive, resilient, and scalable to enable faster, safer, and more delightful software delivery.

Acknowledgments

This milestone wouldn’t have been possible without the incredible collaboration of our product, engineering, and legal teams. And of course, our customers. The feedback they provided shaped the YAML editor into what it is today.

Closing Thoughts

This patent is more than a legal win. It’s validation of an idea: that developer experience matters just as much as functionality. By bridging the gap between raw power and accessibility, we’re making CI/CD pipelines faster to build, safer to run, and easier to adopt.

At Harness, we invest aggressively in R&D to solve our customers' most complex problems. What truly matters is delivering capabilities that improve the lives of developers and platform teams, enabling them to innovate more quickly.

We're thrilled that this particular innovation, born from solving the real-world pain of YAML, has been formally recognized as a unique invention. It's the perfect example of our commitment to leading the industry and delivering tangible value, not just features.
