GitLab is more than just a Git repository hosting platform—it's a full DevOps lifecycle platform that integrates CI/CD, security scanning, project management, Wiki, and deployment. This is the most fundamental difference between GitLab and GitHub. "GitLab's Q4 FY2025 revenue reached $196 million, a 29% year-over-year increase, with paying customers exceeding 9,535" (Source: GitLab Investor Relations) , reflecting the trend of enterprises shifting from multi-tool stacks toward a unified DevSecOps platform. This article outlines the complete path for using GitLab in 2026, from registration to CI/CD pipelines, self-hosting choices, and the real differences from GitHub. What is GitLab: Positioning and Core Architecture GitLab is a DevOps platform developed by GitLab Inc. (NASDAQ: GTLB), headquartered in California, USA, operating in a fully remote work model. Its core value lies in integrating workflows that previously required connecting multiple tools like Jira, Jenkins, SonarQube, Artifactory, and Confluence into a single interface and database. "GitLab was originally written in Ruby on Rails by Ukrainian developer Dmitriy Zaporozhets in 2011" (Source: Wikipedia) . The company was founded in 2014 and went public on NASDAQ in 2021. It offers three usage methods: SaaS cloud version (gitlab.com), self-hosted Community Edition (GitLab CE, MIT licensed), and self-hosted Enterprise Edition (GitLab EE, providing compliance, SAST, and advanced permission management). The biggest architectural difference from GitHub is that GitLab's CI/CD is a "built-in first-class citizen"—the pipeline configuration file .gitlab-ci.yml resides in the same repository as the code and is viewed in the same interface. GitHub Actions, on the other hand, was only launched in 2019, and many enterprises still rely on Jenkins integration. "In JetBrains' 2024 developer survey, GitLab's CI/CD tool usage rate reached 33%, second only to GitHub Actions at 56%" (Source: JetBrains DevEcosystem 2024) . Star
