Slack is part of the family of collaborative tools that are widely used in companies. In concrete terms, it is an instant messaging tool that centralizes all the company's communications. Like any good instant messaging tool, you will be able to chat with all your company's employees or create group discussions.

So far, you tell me, nothing revolutionary. But Slack goes further than that, because it has the ability to connect to all applications that are used in the enterprise and therefore centralize 100% of information flows. In theory with Slack you are supposed to completely reduce the use of internal company emails and a lot of external emails. Slack positions itself at the heart of the organization and once it is installed, it's hard to live without it.

You want to be able to install a Slack locally? Mattermost is made for you. Published by the American company of the same name, this open source solution includes the main functionalities of the team messaging tool in SaaS mode: instant messaging (team or one-to-one), breakdown by thematic conversation channels, private groups, comment threads, file sharing… Mattermost takes over most of the functions of Slack with one main difference: a much less rich app directory.

Trello understands that project management is all about collaboration and visualizing the progress of ongoing tasks. Trello allows you to create projects that take the form of tables in several customizable columns. In each column are the tasks or ideas (visualized in the form of cards) that the collaborators advance from left to right as they progress. In reality, Trello is more like a task manager than a project management tool in the sense that it overlooks cost, time, budget and administrative functions.

If you use Trello to manage your projects and share tasks using the Kanban method, you should know that there is a clone of the service that you can host yourself. It's called Wekan (note the pun) and it will help you organize yourself, either personally or with your friends or colleagues. At a glance, you will see the current status of your projects and can focus only on the tasks that matter most, just like with Trello.

Redmine is a free and open-source software that is worldwide recognized and offers all the necessary functionalities to work in project mode whatever the configuration of your team. Attention however: Redmine requires to be hosted on your servers and to be maintained by a competent team (backup, security, SSL). Its use is therefore not free because of the operating costs involved. The software is particularly suitable for developers but its use is suitable for all types of projects. Redmine is appreciated for its simplicity, customization of ticket formats and workflows. On the other hand the users reproach it for its austere interface (there are however themes) and its rigidity: no drag-and-drop or relative prioritization of tasks for the moment and these uses are at the heart of an efficient project management.

Taiga is an efficient and comprehensive open source platform to manage your agile team projects. The tool has a very minimalist but efficient interface and has won the Best Agile Tool 2015 Award.

Intercom is a software platform you can use to track and engage your visitors, and convert them into your customers. It's one of the most used live chat software in the world and it's perfect for sales, marketing and support. That's what we were using at AlternativeTo before switching to Front because we needed something more complete.

Front is an email management software for teams that integrates with the tools you already use. With Front, you can assign messages to teammates, write comments for internal collaboration or set reminders to respond later. At AlternativeTo, we use Front to respond to customers that use the live chat widget, to answer Facebook & Twitter messages and comments and to read and answer to emails we receive on some shared email addresses.

tawk.to is way simpler than Intercom and Front but it's really good at what it does: live chat that lets you monitor and chat with visitors on your website. It's totally free to use so if you're just looking for a live chat software for your website, you might want to take a look at tawk.to.
