Remember the times of floppy discs? For those under 30, they looked like this, and back in the earlier ages of the internet, they were the way people used to store information.


So, how did developers work back then?

Every project had a master copy, usually under one person's control. Each engineer started his source code from a clone of the master copy and then created his backups. After developing a feature, it would be merged back into the master copy. Most teams had the crucial role of the librarian, in charge of merges and back-ups – which honestly doesn't sound like an entertaining job.

There was only one version of the source tree, and if a bug in an older version was reported while they were in the midst of a significant change, the team would have to wait until that was done before looking for the bug - no matter how critical that bug was. There was no way to store the current version or go back to a previous version.

Yes, it was all very tedious, and engineers were often faced with the brain-destroying task of comparing versions and figuring out what changed or not. A nightmare.

Then version control software arrived, and the workflow started to change.

So – if you are still not convinced – let's go through why you need to use version control software and which are the best 20 free online tools you can find in the market.

What is version control software?

A version control software (VCS) is a type of software designed to make software development more accessible and efficient by helping track changes in the source code (who made them, when they were made), roll back changes, and merge the ones coming from multiple developers.

Let's go back forty years again. In the pre-internet era, working methods were less efficient but not absolute chaos. Why was this?

Because teams were tiny, with no more than five people sitting one next to the other. Today, this would not be possible with large collaborative teams working remotely. Or – let's rephrase it – remote collaboration would not be possible without version control software.

There are three types of version control software:

  • Local Version Control Software: All files are stored on a local disk, and any changes to a specific file are stored as a patch. Patches are like snapshots. They only show the differences between the previous file, but you don't have access to a complete picture unless you go backward.
  • Centralized Version Control Software: There is only one central copy of the software, and every developer needs to “commit” the changes they make for them to be a part of the central copy. The biggest disadvantage is that there can be major code issues if the central server goes down.
  • Distributed Version Control Software: Every developer has a local copy of the software – including all history. The main benefits are that engineers can work offline, and if a server presents any issue, it does not affect the entire project.

Stats and facts of the version control system market

According to a study by Future Market Insights, the global version control system market is anticipated to witness growth in revenue from $629.3 Mn in 2021 to $1,738.6 Mn in 3031 – a compound annual growth rate of 10.7%.

Some other trends:

  • Digitalization and automation: There is a clear transition towards technological advancements that can help reduce human errors. Easy-to-use friendly solutions are the top pick.
  • Digital transformation and app development: Software has emerged as the enabler of digital transformation. There is an increased investment in app development, mainly due to the adoption of smartphones and tablets.
  • Source code management software: Version control systems functioning as standalone applications are now being integrated with various software offerings.
  • Centralized version control systems are preferred: The segment is dominating the market with a share of around 64% by 2021.
  • Distributed version control systems market is growing, though: The segment is expected to grow at a CAGR of 12.7% by the end of 2031.
  • Cloud deployment is growing, too: The cloud segment is expected to register the highest CAGR of 10.4% until 2031 – as they can help reduce overall operating costs.

So, the market is growing – you get it. But how can version control systems help you? Let's dig into the benefits of these fantastic tools.

Why do I need version control software (VCS)?

Even if you are working independently, relying on version control software can be very useful. These are some of the things you can do with a VCS.

Easily track changes

Having organized information about who, what, when, and why changes have been made can be very useful when finding the root cause of a bug, for example, or when you want to use similar functionalities in a new development.

Collaborate remotely

While some people may imagine us developers as introverted people who like to work solely, the truth is collaboration is everything for us. Being able to contribute from anywhere and from any device, no matter the geographical location, is more than nice.

Increase productivity

A better-organized environment and collaboration tool can exponentially boost productivity and expedite product delivery. This is even valuable while working on your own on a project, as the tool allows you to use multiple computers simultaneously.

Reduce conflicts

When each developer works on a different feature of the same software, a separate branch is created. The changes aren’t merged into the original source code unless they are analyzed and green-lighted. No conflicts are allowed.

Rollback and undo changes

Of course, even while VCS helps prevent errors, crashes can happen. But don´t worry! You can easily roll back to a previous version if any mistake is made.

Offsite source code backup

When using a centralized or distributed VCS, a remote instance is hosted off-site to share changes between developers. In an unfortunate scenario like a broken computer, the remote VCS instance will still retain a copy of the source code.

“Since I met GIT, life has become much easier for me at work. It is the perfect platform for teamwork, even if it is only for yourself because it helps you keep the code updated and ordered. With GIT you can version the work, having several alternatives of the same branch, add comments and keep the code clean. The platform compresses the code and helps you decrease time by uploading large amounts of changes very fast”.

“It's a steep curve to learn, but well worth it”.

Git pros

  • Good for collaboration
  • Fast upload of changes
  • Widespread (tons of libraries)

Git cons

  • Steep learning curve
  • Clashes occasionally

2. Github

When we start reviewing tools, we always hope to find an unknown exceptional solution that no one has seen yet.

The truth is that most popular tools are popular for a reason, and being widespread increases the efforts for new developments and improvements.

Sorry to disappoint you guys – but this time, our decision will be between Git and Github, the two most capable version control software.

While Most third-party platforms support git on the market, it is scalable and good for collaboration. It does have a steep learning curve and is not the friendliest UI.

Github, on the other hand, apart from version control functionality, offers a place online to store and collaborate on projects. Plus, its free plan comes with unlimited public and private repositories! It looks like we have a winner.

However, many other options are also worth taking a look at. Check the comparison table of our preferred 20 free version control software:

Repository model Hosting Features Adoption & support Ease of use
Git Distributed Cloud-based somewhat
Github Distributed Cloud-based and self-hosted
Apache Subversion (SVN) Centralized Cloud-based and self-hosted Limited somewhat

What are the benefits of version control software?

Version control software can help easily track changes and collaborate remotely, reducing merge conflicts and increasing productivity. Other useful benefits are the possibility to roll back and undo changes and having an off-site source code backup (the latter is a feature that not all the systems offer).

Is a client-server model better than a cloud-based one?

No. Client-server systems use the in-house infrastructure, while cloud-based storage is off-site in a third-party vendor and is accessible via the Internet. Reputable cloud service providers have multi-level firewalls and other robust security tools – a level of protection that would be expensive for a company to sustain.

Is distributed version control better than centralized version control?

Both have pros and cons. While distributed version control is faster because you don't need to communicate with the remote server for every command, centralized systems are easier to use and perform better with binary files.
