Smarter PR Reviews: Inline comments, keyboard shortcuts, and faster diffs reduce context switching. Optimized for Scale: Instant file tree and change listing performance even in large monorepos. Seamless Navigation: Effortlessly move between branches, commits, and repos without losing context. Unified Design System: A consistent, intuitive UI across the entire Harness platform.
At Harness, we know developer velocity depends on everyday workflow. That is why we reimagined Harness Code with a faster, cleaner, and more intuitive experience that helps engineers stay in flow from the first clone to the final merge.
Why Developers Love the New Experience
Smarter Pull Request Reviews
Review diffs and conversations without constant context switching. Inline comments, keyboard shortcuts, and faster file rendering help you focus on the code instead of the clicks.
Faster File Tree and Change Listing
The new file browser is optimized for large repositories. You can search, jump, and scan changes instantly even when working with thousands of files.
Seamless Repo Navigation
Move between branches, commits, and repositories without losing your scroll position or comment state.
Unified Harness Design System
The entire interface now uses the same design system as the rest of the Harness platform, which reduces the learning curve and makes navigation feel natural.
Why Leaders Should Care
Every inefficiency in the developer experience is a hidden tax on velocity. Harness Code removes those blockers so your teams:
- Ship faster by reducing wasted time in code reviews.
- Collaborate better with a clear, intuitive UI that scales across teams.
- Standardize workflows with a design system that unifies the Harness platform.
All 500-plus Harness engineers are already using the new experience, proving it scales in real enterprise environments.
Seamless Rollout, Zero Migration
Adopting the new experience is effortless:
- Beginning of October 2025: Available for all users (opt-in).
- End of December 2025: Legacy UI deprecated.
- Beginning of January 2026: New experience becomes default.
There is nothing to migrate. Simply click 'Opt In', and your repositories, permissions, and integrations will continue to work as before.
What’s Next
The new Harness Code experience is only the beginning. Coming soon:
- Even faster repo load times.
- More native AI support for PR reviews and commit insights.
We’re continuing to invest in developer-first features that make Harness Code not just a repository, but the heartbeat of your software delivery pipeline.
