CodeIgniter Library: 77 Free Scripts, Addons, Tutorials and Videos

CodeIgniter is the brainchild of Ellis Labs and one of the more popular PHP frameworks available. It’s gained a reputation as a lean, mean, easy-to-learn framework that anyone comfortable with PHP can get up and running with in a few days.

CodeIgniter is fixin’ to blow up even more with the release of ExpressionEngine 2.0, currently in Beta, which is built on top of the CodeIgniter framework. Sounds great and all, but ExpressionEngine ain’t cheap…$299 for the commercial version…so while you sit around wondering if ExpressionEngine is a CMS you want to get in to, why not get familiar with it’s CodeIgniter foundation using these 802 77 totally free scripts, addons and tutorials?

Free/Open Source CodeIgniter Scripts

 

  1. CodeIgniter Logo

    CodeIgniter is a great, open source, PHP framework for building web applications

    BackEndPro

    • BackEndPro is a control panel for developers written in PHP for the CodeIgniter framework. It provides the beginnings of a solid CMS for those wanting to build their own without the need to reinvent the wheel. Authentication, permissions, and basic look and feel for a back end control panel are already done for you, so you have more time to focus on building your empire.
  2. BambooInvoice

  4. ExciteCMS
    • If ExpressionEngine’s $299 price tag has you down, ExiteCMS is a completely free content management system built on CodeIgniter. It’s still in it’s “Alpha 2″ release, but looks pretty promising.
  5. PyroCMS
    • This CMS is a treat. Excellent code, and a very simple layout resembling ExpressionEngine 1.0 in many ways. It’s lightweight and, because it’s built on CodeIgniter, is easily expandable.
  6. Kohana
    • This isn’t a script, but a framework branch of CodeIgniter that solves a number of its shortcomings. Check out Onwired’s blogfor a great summary of these shortcoming, but some of the highlights are:
      • Strict PHP 5 OOP code structure
      • Better use of modules
      • Cascading architecture
      • Adds an ORM library to help with building database-driven applications
      • Makes writing libraries a bit simpler
  7. Ionize CMS
    • Ionize is a content management system built on the CodeIgniter framework designed with one thing in mind: flexibility. Utilizes a template engine to make things a little more simple for the designers out there.
  8. Linkster Link Directory
    • Linkster is a link directory script built with CodeIgniter. Check out the demo at the Linkster site for an example of it’s use.
  9. MyClientBase
    • MyClientBase is another open source invoicing script developed for freelancers.
  10. MyFina
    • MyFina is a personal financial management system. They offer a hosted demo on the website and if you like what you see you can download the source and install it on your own server.
  11. 68kb
    • 68kb is a knowledge base script featuring unlimited categories, search-engine friendly URLs, a glossary of terms, comments, attachements and a stats package. The demo is a bit lacking so you’ll be better off downloading the source to give it a try.
  12. CIMyAdmin
    • CIMyAdmin is meant to act as a replacement to phpMyAdmin for database management. CIMyAdmin claims to be a cleaner, faster, better and stronger MySQL admin tool. It’s lightweight, secure and skinnable.
  13. Sweetcron
    • Sweetcron is a self-hosted lifestreaming application that supports themes & plugins. That basically means it’s a simple blog that’s really, really easy to update. You can check out the developers’ lifestream for an example at http://yongfook.com/.
  14. Unravel The Music Clone
    • Unravel The Music, according to the author, is a music lyric website built on the CodeIgniter framework that was closed down when the supplier of lyrics went out of business; so the developer released the source for free. It features, user activity feeds, journals, blogs, most discussed lists, user karma system, APIs, memcache integration, user profiles, file uploading, artist/album/song tagging, amazon integration, issue reporting, and a bit more. Seems like it could be a great starting point for someone looking to build this kind of site.
  15. Vunsy
    • Think of Vunsy as a website Kernel, used as the foundation for building a complete web application. It includes Dojo, KFM Ajax for image resizing and code editor, a data mapper for ORM, an online CRUD system, unlimited pages and subcategories, advanced permissions, and a package manager.

  1. Hey,

    Thanks for putting a few of my scripts and tutorials on this list, but I noticed a few oddities.

    ReduxAuth had been out o active development for over a year and has been picked up by Ben Edmunds under the new name Ion Auth.

    FreakAuth Light has not been actively developed since CodeIgniter 1.5.2 and it’s my guess that it’s no longer compatible.

    Rapyd Framework needs no guessing, it isn’t compatible and hasn’t been since CodeIgniter v1.6.0 was released.

    The Random plugin is now useless as it duplcates core functionality found in CodeIgniters String Helper.

    Other than those points, this is a great list and a good starting point for anyone needing inspiration with their first CodeIgniter apps.

    • Thanks for stopping by Phil! I updated the post with the help of your comment, I appreciate you pointing those corrections out to me!

  2. This is a really great list. Great stuff. Good job :]

  3. Great list. Thanks for putting in the time to put this together John. It seems CodeIgniter is missing a good CRUD builder. Can’t decide whether a passive FormIgniter style system or an active one would be best. Either option would be hugely useful and a massive timesaver. It seems crazy to be manually hand coding such a routine, standardised chunk of code.

  4. Thanks for mentioning BackendPro on your list, its nice to see others getting to use my tool and know about it.

  5. Thanks John, this list is AWESOME. As a CodeIgniter user, it’s really nice to see all these useful links together…!
    Thanks again, I’m twittering this url right now!

    Bruno

  6. Great list, Thank you for sharing all these stuff to all ……….

  7. Thanks for the list. This has become my “table of contents” kind of list for my work related to Code Igniter. I refer to this almost everyday.

    One note: FreakAuth may not be actively maintained, but it works perfectly fine in the latest CodeIgniter and is a great auth library. I just using it for my current project and am very happy about it.

  8. Great list, Thank you for sharing all these stuff to all …Good job man

  9. Thanks for this list. Without this I would never have found FormIgniter! Thanks again.

  10. Hello,
    I like add here three more ones:

    1. tweetsigniter — twitter codeigniter library here .
    2. Advanced layout library – see it on here.
    3. My input library – see it on here

  11. I am part of the Ionize CodeIgniter CMS development team, and I am always happy and proud to find out someone has blogged about our project.

    Many thanks, and don’t hesitate to try Ionize, it’s growing fast project !

  12. Great post. Adding a reference for it on my blog.

  13. Great list, this is a really useful bookmark for me as I’m just starting out with CodeIgniter… Thanks for posting.

  14. If you’re intersted in video tutorials you may want to check out http://codeigniter.tv. It features Codeigniter video tutorials.

  15. One item I was expecting to see here was Bonfire. It is an HMVC implementation and is the foundation of a lot of new CI apps.

  16. Hi,

    This list would be good if there were not sooooo many dead links.
    I clicked on 10 items and 8 of them 404′d.

    Given that codeignighter is a tool for developers, perhaps a little bit of code to check for a 404 before displaying the link would make this list more future proof… the internet is full of old and out of date information this days.

    • Hey jez, thanks for the heads up on the dead links. Looks like nearly all the dead links are from the CodeIgniter.com domain (it seems they move some resoureces and didn’t implement 301s).

      I’ll get those cleaned up at some point.
