Slack is so slow! Here are 5 lightweight open source alternatives

Slack is a popular communication soft bloatware for teams. It allows you to chat with other users, groups and in channels (rooms), like good old IRC. However, the main issue with Slack is that is it way too bloated and loads too slowly. It takes 105 requests, 18 MB of data and 30 seconds to load!


So if you are concerned about your data plan, performance, or security of your business correspondence stored on third party servers, you should consider one of the lightweight open source web alternatives for Slack:

Let's Chat - loads in ~5 seconds:


JabbR - loads in ~8 seconds:


Candy - loads in ~5 seconds:


Echoplexus - loads in ~6 seconds:


Shout - finally a web IRC client, loads in ~5 seconds:


Each of them is open source, so you can install it for free on your private server and keep your internal business communication secure.

UPDATE: There is a new project called Mattermost - check it out!

Run desktop apps, WebKit and Chromium web browser on Firefox OS!

Firefox OS is a fully open source mobile platform, but it lacks many full-featured apps. Starting from today, RollApp provides full desktop apps for Firefox OS, including LibreOffice, OpenOffice.org, Tomboy, KeePassX and File Roller. The apps are loaded on RollApp cloud servers and are streamed using WebSockets, which make them run smoothly.


You can even run the Web browser, powered by WebKit, which you can start by typing any URL in Tomboy and clicking on it.


The Web browser is really fast, it gets 6568 points in the Octane benchmark.

UPDATE: Now you can run Chromium web browser in Firefox OS! It scores 9677 points in the Octane benchmark.



All RollApp apps can be found in the Firefox Marketplace.
