Open source options
Fossil
open-source
All-in-one distributed version control with built-in bug tracking, wiki, and web interface in a single executable.
GitLab
Per-user · Cloud / On-prem · Free trial
GitLab keeps source control, pipelines, a container registry, security scanning and project tracking inside one application instead of five integrated ones. The self-hosted edition is the real decider for organizations under data sovereignty rules that stop source code from residing in someone else's cloud, and it is licensed per user either way.
Mercurial
open-source
Distributed version control system designed for speed and scalability with a simple, intuitive command set.
Other version control tools

Azure DevOps
Per-user · Cloud · Free trial
Source control, build and release pipelines, work item boards, and test plans sit inside one Microsoft suite. That makes Azure DevOps behave as a platform, not a collection of point products. Organizations already inside the Microsoft ecosystem often start here on licensing proximity to subscriptions they already hold. It scales from small teams up to complex multi-project enterprise setups.
Bitbucket
Per-user · Cloud · Free trial
For a shop already running Jira and Confluence, Bitbucket is the path of least resistance: issue-to-pull-request linking works natively, Pipelines covers CI/CD without a third-party runner, and the bill arrives per user on Atlassian's cloud. Outside that ecosystem the calculation changes, since GitHub and GitLab carry broader community ecosystems around them.
GitHub
Per-user · Cloud · Free trial
Code hosting and code review here have become the default for open source and enterprise software teams alike. GitHub Actions lives in the same platform, so CI/CD work does not mean switching context to a separate system. Access controls and audit logs on the enterprise plan cover most security and compliance requirements, and seats are priced per user.
Perforce Helix Core
subscription
Enterprise version control system built for large-scale binary assets, game development, and regulated industries.
Plastic SCM
freemium
Version control system optimized for game development and large binary files with visual branch management.
Common questions about open source version control tools
Is open source version control tools really free?
+
The license is free, but hosting, maintenance, patching, and upgrades replace the vendor's license fee. Teams without dedicated ops resources often spend more on self-managed open source than on a managed commercial alternative.
When should I choose open source over commercial version control tools?
+
Open source is strongest when you need full code control, on-premises deployment for compliance, or want to avoid vendor lock-in. It is weaker when your team lacks the ops capacity to maintain, patch, and scale the deployment.
What should I check before deploying open source version control tools?
+
Check community activity (commits, issues, and releases in the last six months), commercial support options, documentation quality, and the total operational burden against a managed alternative. A dormant project with no commercial backing is a risk.
