The Rise of GitLab: From a Ruby Side Project to a $15B DevOps Giant

From a Solo Side Project to a $15B DevOps Giant: The Inside Story of GitLab

Back in 2011, a Ukrainian developer named Dmitriy Zaporozhets was frustrated. He was using a self-hosted Git repository tool, but it was clunky and slow. So he did what any good developer would do — he built his own. That side project, initially called "GitLab," was nothing more than a few Ruby scripts glued together. He never imagined it would one day challenge Microsoft’s GitHub and become the world’s largest all-remote company.

The "Better GitHub" That Started with 100 Lines of Code

GitLab’s origin story is refreshingly simple. Zaporozhets needed a fast, lightweight way to manage Git repositories on his own server. At the time, GitHub was already the king of hosted code, but self-hosted options were painful. So he wrote a minimal Ruby on Rails application that could do basic repo management, merge requests, and code reviews. He posted it on Hacker News.

The response was immediate. Dozens of developers asked for features. Within months, the project had a small but passionate community. Zaporozhets realized he couldn’t scale this alone. Enter Sytse "Sid" Sijbrandij, a Dutch entrepreneur who saw the potential. In 2013, Sid offered to help with business development, and together they founded GitLab B.V. in the Netherlands.

The Pivot That Changed Everything

For the first few years, GitLab was just a code hosting tool — a "self-hosted GitHub alternative." But around 2015, something clicked. The team noticed that companies using GitLab weren't just storing code. They were running CI/CD pipelines, managing issues, and even deploying applications directly from the platform.

Instead of building isolated features, Sid and Dmitriy made a radical bet: unify the entire DevOps lifecycle into one application. No more stitching together Jenkins, Jira, and Slack. No more "tools sprawl." They would build everything — from code review to monitoring to security scanning — in one seamless product.

This was risky. GitHub, Atlassian, and countless startups were focusing on individual tools. GitLab bet that developers would prefer a single, integrated platform. The industry scoffed. "Jack of all trades, master of none," critics said.

They were wrong.

The All-Remote Bet That Paid Off

By 2017, GitLab had 1,000 paying customers and was growing fast. But the company faced a problem that would break most startups: how to hire the best talent anywhere in the world without expensive offices.

Sid made a decision that now seems visionary but was then considered reckless: Go all-remote. No headquarters. Zero offices. Every single employee works from home or a coworking space. At the time, almost no major tech company had done this. Even "remote-friendly" companies like Basecamp still had a central office.

GitLab embraced it ruthlessly. They documented everything — every decision, every meeting, every policy — in a public handbook. They built async communication tools. They hired people from 65+ countries. The result? Lower costs, higher productivity, and a talent pool that spanned the globe. Today, GitLab is the poster child for remote work, with the largest publicly available remote work handbook on the internet.

Going Public and Taking on Microsoft

In October 2021, GitLab went public on Nasdaq under the ticker "GTLB." The stock opened at over $100, valuing the company at more than $15 billion. It was a stunning validation of the integrated DevOps bet.

But the real competition had just begun. In 2018, Microsoft acquired GitHub for $7.5 billion. Many developers feared GitHub would become a closed, enterprise-focused tool. GitLab positioned itself as the open, flexible alternative. They offered a free self-hosted version (GitLab CE) that any company could run on their own servers, and a paid enterprise version (GitLab EE) with advanced features.

The battle lines were drawn: GitHub + Microsoft's cloud monopoly vs. GitLab's open-core, anti-lock-in philosophy. GitLab leaned hard into features GitHub lacked — built-in CI/CD, container registry, security scanning, and a "single DevOps lifecycle view." While GitHub played catch-up, GitLab kept shipping.

Where GitLab Stands Today

As of 2025, GitLab has over 30 million registered users and more than 100,000 organizations using the platform. It’s the go-to choice for companies that want to own their DevOps pipeline end-to-end — especially regulated industries like finance, healthcare, and government that can’t rely on public cloud services.

The company now offers a dizzying array of features: version control, CI/CD, code quality, security scanning, performance monitoring, project management, and even AI-powered code suggestions. The "side project" that started as 100 lines of Ruby is now a 2 million+ line codebase maintained by thousands of contributors.

The Lesson: Start Small, But Think Big

GitLab’s journey holds a simple but powerful lesson: Don’t try to be perfect. Start by solving one problem really well, then evolve. Dmitriy didn't set out to build a $15 billion company. He just wanted to fix his own frustration with code hosting. But by staying close to users, being willing to pivot, and making bold bets on integration and remote work, that side project became a platform that changed how the world builds software.
