It's become a annual tradition at Datamation to publish an complete roundup of all the open source projects we've featured throughout the year. This year's update includes a vast trove of open source software: 1,343 different projects, from 138 different categories, including two brand new categories.

This year's open source list has quite a few new additions related to cloud computing, the Internet of Things (IoT) and artificial intelligence (AI). It also has quite a few new projects related to marketing software.

Please note that this is not a ranking. The projects are organized into categories and then listed alphabetically within the categories.

As always, if you know of additional open source software that you'd like to see us cover in future lists, feel free to note them in the Comments section below.

Best Open Source Software for Windows 10

Sure, you’re a Windows user – in fact you’re using an up to date Windows OS. But in today’s world, it’s still entirely likely you’re looking for the best open source software for your PC. This list gathers some familiar names with lesser known apps, all with an eye toward boosting your Windows 10 machine. Which app do you think is the best open source software for Win10

Open Source Software: Top Sites

There are countless websites that offer extensive lists of open source software to download. But finding the best open source website is easier said than done. To help, we’ve compiled a list of the very best open source websites – let the downloading begin.

Open Source Replacements for Proprietary Business Intelligence Software

In this aggregation of open source BI tools, you’ll certainly see some famous names: MySQL, Pentaho, along with some names that get less buzz as well. Of course in the rapidly changing business intelligence market, today’s big names could easily be surpassed over time by a little known tool – feature sets change quickly. Which open source BI tool on this list will be most popular in the years ahead?

Open Source Replacements for Windows XP

There’s no debate about it: Windows XP is an aging operating system. For those looking to replace it – and yes, it’s time – with an open source operating system, this is the list for you. This survey of open source operating systems includes superstars like Ubuntu along with solid players like Knoppix. Come on, replace that old Windows OS!

Open Source Replacements for Popular Financial Software

It makes perfect sense: you’re using financial software to track your expenses, so naturally you’re interested in open source financial software. Open source – much of which is a free download – is made for penny pinchers. The open source financial software in this list may save you, in some cases, hundreds of dollars. A penny saved is a penny earned.

Open Source Replacements for Expensive Apps

It’s clear that, as value propositions go, this one’s a no-brainer: replace your expensive apps with low-cost or free open source applications. Certainly there’s debate about feature sets: some commercial software partisans argue that the feature sets for open source applications do not match their commercial counterparts. Undoubtedly the other side disagrees strongly. You can be the judge – download a few open source applications and check them out. Do they compare?

Open Source Replacements for Popular Small Business Software

Open source business software is, in many cases, the ideal solution for small businesses. If you’re as cash-strapped as many SMBs, you’ll certainly want to look at this list of open source business software. Bottom line: free or low cost is better than high priced, even if that requires giving up some familiar software choices to explore options that are lesser known. If money is tight, open source business software can often be a useful option.
