About this Free Projects library
All source code projects on itsourcecode.com are released free of charge under the MIT License (unless otherwise noted) for educational use, including BSIT, BSCS, BSIS, and IT-related capstone projects. You can modify, extend, and use the code commercially. We ask only that you cite the source in your capstone documentation as required by academic integrity standards.
The library is maintained by PIES Information Technology Solutions, a Philippine-based development team. New projects are added monthly. If you need a custom capstone built for your specific defense requirements, see our Hire Us page for development services.

Frequently Asked Questions
Are all the projects on itsourcecode.com really free?
Yes. Every project in this hub is free to download, modify, and use, including for BSIT, BSCS, BSIS, and CSE capstone projects. All code is released under the MIT License unless otherwise noted, which means you can also use it commercially. There is no signup, no email gate, and no payment. We do ask that you cite itsourcecode.com in your capstone documentation as required by academic integrity standards, and that you modify the project substantially before submission, because panels in 2026 actively check for known capstone codebases.
Which programming language should I choose for my BSIT capstone in 2026?
For Philippine BSIT capstones, PHP + MySQL is the most accessible: lots of local industry demand, easy hosting on shared servers, and panels are familiar with it. Python (Django or Flask) is the best choice if your project includes AI/ML features. Java with NetBeans is preferred by panels emphasizing OOP discipline. VB.NET works for desktop-focused capstones. Laravel is gaining popularity as a modern PHP framework alternative. Choose the language you can defend confidently, that matters more than which one is currently trendy.
Do the project downloads include database files and setup instructions?
Yes. Every project download includes the source code, the database SQL file (typically MySQL or SQL Server), and a README with basic setup instructions. For larger systems we also include screenshots and test credentials. If a project page is missing any of these, leave a comment on that project's article. Our team monitors comments daily and updates downloads as needed.
Where can I find UML diagrams to document my project?
Visit our UML Diagrams Library for 300+ free UML diagrams covering ER, DFD, Class, Use Case, Activity, Sequence, Component, and Deployment diagrams for common capstone systems including Library Management, Hotel, Hospital, Restaurant, School, ATM, Payroll, and E-commerce. Each diagram can be downloaded as a reference image and adapted to your specific system's terminology.
How do I write the Chapter 1-5 documentation for these projects?
Use our Chapter 1-5 capstone writing series for step-by-step guides with Philippine BSIT-specific templates and real examples for each chapter: Chapter 1 (Introduction), Chapter 2 (Review of Related Literature), Chapter 3 (Methodology), Chapter 4 (Results and Implementation), and Chapter 5 (Summary, Conclusions, Recommendations). The series pairs perfectly with any project from this hub.
Can I request a custom project that's not in the library?
Yes. PIES Information Technology Solutions offers custom capstone development for Philippine BSIT and BSCS students. We can build complete systems in any of our supported stacks (PHP, Python, Java, VB.NET, Laravel, Android), produce full Chapter 1-5 documentation, and provide consultation for project defense preparation. Pricing depends on project scope. Visit our Hire Us page to request a quote.
What's the difference between this Free Projects hub and the Final Year Projects hub?
This Free Projects hub focuses on the source code itself: downloadable systems organized by programming language and project type. The Final Year Projects (FYP) hub focuses on the academic side: capstone ideas, Chapter 1-5 writing guides, defense preparation, and curated topic lists for AI, IoT, ML, and Web projects. Most students use both: pick a project from this hub, then use the FYP hub to write the supporting documentation.
