I'm looking for a free tool (ideally open source and web based) that allows sharing of resources across a small team (approx. 10 members) across different locations.

I'd like to be able to share links, notes, documents, images. It is necessary to have tags and/or a search functionality, as there are likely to lots of small notes/documents etc on different topics.

Added bonus would be if it is possible to comment on any of these, or if it is possible to rate these/vote them up or down.

Any suggestions?

@iglvzx why not make it an answer? – Bibhas Feb 7 at 19:23

@ssoliinger if you were not looking for free tools, I'd have suggested Evernote premium. – Bibhas Feb 7 at 19:28
@Bibhas Ok. Done! – iglvzx Feb 7 at 19:31
@Bibhas - Evernote Premium does look fantastic (given it +1), unfortunately I don't have a budget for this at the moment (hence the requirement for a free product). – ssollinger Feb 8 at 9:57

Fun fact: the Super User community uses Trello for managing blog posts.

Seems good. Going to use it for some days. :) – Bibhas Feb 7 at 19:37
Is it possible to attach something in Trello? Trello is perfect for notes, but can I share documents or images? How does it handle links - just as plain text in a note? – ssollinger Feb 8 at 10:03
@ssollinger Yes! You can attach images and files as large as 10MB, plus Trello supports MarkDown for links and formatting. trello.com/guide – iglvzx Feb 8 at 22:13

You're looking for a collaboration tool. Google Wave, before it was shuttered, sounds like exactly what you're looking for.

There are several open source collaboration tools (think, free versions of Microsoft Sharepoint) and you'll need to decide what features you want.

  • Should it be local or hosted? Do you want to have to manage, support, and update it yourself or can you deal with it being hosted elsewhere on the internet?
  • If you're going to run it locally, what sort of system can you host it on? What OS? What sort of power does the host system have?
  • If you're having it hosted elsewhere or using a free web-tool, what sort of access do you have to it? Does it have local apps you install? Does it have mobile app versions if your team uses smart phones or tablets?
  • What is the target use? Is it to be used for project management? Real-time collaboration? Generic file sharing? Note-taking/mind-mapping/brain-storming?
  • Does it have to be able to host files internally or can it merely reference files using links?
  • Who has to own the data? Is being able to move the data easily between various solutions important?

Answering these questions will allow you to pin down what sort of tool you actually need.

Based on this being a small team, it's more likely you'll be looking for a tool that's hosted elsewhere. A remotely hosted tool will also allow for more easy access by your remotely located team members. In fact, I'd completely avoid a self-hosted machine unless you just really have to get into that level of management.

So then you need to decide if you want a Wiki system, or a more proprietary system. Many web-based collaboration systems are free for small teams and with limited features.

Wikipedia has a list of Collaborative Software that includes web-based tools, but only includes a few hosted solutions. It also includes a feature metric that could be very handy for feature comparison: http://en.wikipedia.org/wiki/List_of_collaborative_software

The last 2-3 years have seen quite a growth in the market of hosted collaboration platforms, so the good news is there's lots to choose from. The bad news is that this can make it hard to choose between offerings.

You are asking more questions than you are answering! Thanks for the detailed answer though. Google Wave is a good tip, so I give you +1. If anyone is interested: alternativeto.net/software/google-wave has alternatives. "Kohive" looks promising on that page (kohive.com). – ssollinger Feb 8 at 11:36

A Wiki or a StackExchange (or similar) site are worth a try. Many open-source communities use a Wiki as a base for their operations.

You can try freeforums.org. You can get your own sub domain like

myteam.freeforums.org and you can make the forum invite only/moderator approval only.

It'll be a forum that only you guys (The team) can access. The forum software is phpbb and very easy to work with. ^^

Here are some other tools I found during my research, in case these help anyone else reading this question:

Lino (http://linoit.com):

Seems great to share notes, the sticky notes look very pretty, it can handle URLs (incl. comments), can upload files, but there is a limit to the number of files/attachments that can be opened in the free version, and I think it won't work for a large number of resources (no search, the sticky notes fill the screen pretty soon). May be a good option if there is not too much information to share.

Open Atrium (http://openatrium.com)

Requires a web server (based on Drupal). It includes a blog, a wiki, a calendar, a to do list, a shoutbox, and a dashboard to manage it all. Looks great, but haven't tested it yet (because it requires a web server).
