Introducing Zumbro: Slash Tech Debt with Automated Code Fixes
We’re thrilled to make the biggest announcement in Caparra’s history: today, we launch the Zumbro app for GitHub.
Zumbro is the DevOps automation tool that helps your team define, apply, and enforce engineering standards, without adding overhead. If you’re looking to improve teamwork, reduce technical debt, and accelerate shipping velocity, Zumbro gives you the foundation to do it, right inside your GitHub workflow.
Zumbro is available now in GitHub, and in just a few minutes Zumbro can be improving your codebase.
Let’s get to know Zumbro: what it is, how it works, and why we believe it can transform how your team builds and maintains software.
Say hello to Zumbro from Caparra
What is Zumbro?
Zumbro is a GitHub-native tool that brings DevOps best practices to your whole team by making it easy to agree on standards, apply them to existing code, and enforce them on every new commit.
If you’ve ever struggled to get everyone on the same page about "what good code looks like," or wished there were a smarter way to clean up old code without burning your team out, Zumbro is built for you.
With Zumbro, you don’t need to wait for an audit or organize a cleanup sprint. You get continuous, automated improvement, built directly into your development lifecycle.
How Zumbro Works for You
Zumbro accomplishes three core missions for your team:
1. Define Your Team’s Standards
Every great team has its own definition of high-quality code. Zumbro helps you capture and codify those standards in one place.
Whether you care about security, readability, test coverage, naming conventions, or something else entirely, Zumbro gives you a way to define those expectations so that everyone—new hires, senior engineers, and even contractors—can stay aligned.
Clear standards reduce review friction, improve communication, and build a healthier codebase over time. And unlike traditional documentation or a README file, these standards actually get used, because Zumbro applies them automatically.
2. Modernize Legacy Code
Once your standards are defined, Zumbro gets to work. It inspects your GitHub repos, one file at a time, and finds where the code falls short. Then it opens pull requests with fixes that result in clean, standards-compliant code.
No nagging, no tedious code reviews. Just quiet, continuous upgrades that reduce technical debt and bring old code up to modern expectations, without slowing anyone down.
Think of it as having an extra engineer on the team who specializes in cleanup work, never complains, and always opens helpful PRs.
Zumbro applies your code standards to legacy code, one PR at a time.
3. Enforce Standards on Every Commit
Once your legacy code is cleaned up, how do you prevent it from drifting again? Zumbro handles that too. It sets up automated pre-commit hooks that apply your team’s standards to every new change.
This is what DevOps pros mean by “shift left.” Instead of catching problems at the end of a long pipeline, Zumbro enforces standards at the point of change. That means better code, earlier feedback, and faster releases.
Zumbro Is Built with DevOps, for You
Caparra’s mission is to bring DevOps principles to the entire software team. We know how much time gets wasted on repetitive tasks that you haven’t gotten around to automating.
Zumbro is built with input from DevOps engineers around the world: from early-stage startups to complex enterprise teams. What they told us, over and over, is that they want more time for high-value work, and less toil required to improve their systems.
That’s why we made Zumbro do the heavy lifting: reviewing code, opening pull requests, enforcing consistency, and getting out of the way when it’s not needed.
Zumbro embodies one of Caparra's core values, Brilliance in the Basics. DevOps often feels hard and complicated, but in reality applying simple concepts like code consistency and automation are the foundation of great software delivery.

Zumbro is available now in GitHub, and setup takes just a few minutes.
Zumbro: DevOps for Everyone
For years, DevOps was seen as “advanced studies” or arcane wizardry. But as more teams adopt continuous delivery and platform engineering, it’s clear that DevOps practices like automation, standards enforcement, and shift-left testing are valuable for everyone writing code.
Zumbro brings those practices into the heart of your development workflow. You don’t need a giant platform team or a complex pipeline to start using it. If your code lives in GitHub, Zumbro is ready to help.
Try Zumbro Today
We couldn’t be more excited to share Zumbro with the world. It’s the result of months of work, dozens of customer interviews, and the belief that great teams deserve great tools.
