What Is Open Source?
Last updated: April 2026 · Verified by Jay Pipaliya, Founder & CEO at JK Tech Hub
Quick Answer
Open source software has its source code publicly available for anyone to view, modify, and distribute. It's developed collaboratively by communities and companies, often producing higher-quality software than proprietary alternatives — Linux, React, PostgreSQL, and WordPress are all open source.

How Open Source Works
Open source projects are typically hosted on GitHub. Contributors submit 'pull requests' — proposed code changes that are reviewed by project maintainers. If the change improves the project, it's merged. This crowdsourced development produces thoroughly reviewed, high-quality code.
Most open source projects have a governance structure — core maintainers who make final decisions, regular contributors who submit improvements, and a community of users who report bugs and request features.
Open source licenses define how the software can be used. MIT and Apache licenses allow commercial use with minimal restrictions. GPL requires that derivative works also be open source — important to understand when building commercial products.
Open Source Explained in Detail
Open source is a development philosophy and licensing model. The source code is publicly accessible, typically on GitHub. Anyone can study how the software works, fix bugs, add features, and share improvements. Popular licenses include MIT (very permissive), Apache 2.0 (permissive with patent protection), and GPL (copyleft — modifications must also be open source).
Open source powers the internet. Linux runs 96% of web servers. React builds 40%+ of frontends. PostgreSQL and MySQL store most of the world's data. Node.js, Python, Docker, and Kubernetes are all open source. Most commercial software is built on open source foundations.
Companies contribute to open source for strategic reasons. Google open-sourced Android and Kubernetes. Facebook open-sourced React. Microsoft acquired GitHub and open-sourced .NET. Open source creates ecosystems that benefit the sponsoring company while advancing the entire industry.
For businesses, open source means access to world-class software without licensing fees, freedom from vendor lock-in, and the ability to customize tools for specific needs.
Why Open Source Matters for Your Business
Open source saves businesses millions in licensing fees. PostgreSQL instead of Oracle saves ₹50+ lakhs annually. Linux instead of Windows Server saves significant licensing costs. The quality often matches or exceeds commercial alternatives.
Open source eliminates vendor lock-in. If you use PostgreSQL, no company can raise prices or discontinue your database. The code is yours, and a global community ensures it keeps improving.
For developers, contributing to open source builds skills, reputation, and career opportunities. Many companies hire based on open source contributions visible on GitHub.
Real Examples
Who Uses Open Source?
Real companies using this technology successfully.
Linux
Open source operating system running 96% of web servers, all Android phones, and most supercomputers worldwide
React (Meta)
Open source UI library used by millions of developers — Meta benefits from community contributions while setting the web standard
WordPress
Open source CMS powering 43% of all websites — the most successful open source project by adoption
How JK Tech Hub Uses Open Source
JK Tech Hub builds on open source technologies exclusively — React, Next.js, Node.js, PostgreSQL, Docker, and Linux. We benefit from community innovations and contribute back when possible.
Using open source means our clients have zero licensing costs for the technology stack, full code ownership, and no vendor lock-in. The same code runs anywhere — from AWS to on-premise servers.
We help clients evaluate open source options for specific needs — choosing between open source and commercial solutions based on support requirements, compliance needs, and total cost of ownership.
Myths Busted
Common Open Source Misconceptions
"Open source means free" — The software is free, but implementation, customization, hosting, and support have costs. 'Free as in speech, not free as in beer.'
"Open source is less secure" — Open source is often MORE secure because thousands of developers review the code. Proprietary software hides vulnerabilities through obscurity.
"Open source means no support" — Major open source projects have commercial support options (Red Hat for Linux, EnterpriseDB for PostgreSQL) and active community forums.

Common Questions
Frequently Asked Questions
Quick answers about open source.
What is open source in simple words?
Open source software has its code publicly visible. Anyone can see how it works, suggest improvements, and use it freely. Linux, React, and WordPress are open source.
Is open source software safe to use commercially?
Yes, but check the license. MIT and Apache licenses allow commercial use freely. GPL requires your modifications to also be open source. Most business use is fine under MIT/Apache.
Why do companies open source their code?
To build ecosystems (Android), attract developers (React), reduce maintenance burden through community contributions, and establish industry standards.
