Free IRC client for engineering chat - no install

Free IRC client (Internet Relay Chat) to chat on any IRC room on engineering, innovation product development, or get advice on any topic. Except for bots, you usually find passionate people ready to help. No Install needed. just select one of the networks, provide your pseudo and enter a room. We have some room suggestions, but once entered, use the room tab to search for any other room or topic.


Note1:
the tools below allow one network per IRC client; use the menu on the right or scroll down to access each of the 5 main networks available. Some rooms are suggested for each network, but use #XXX function once log to display all the rooms (hundreds to thousands).
Note2:
be careful on any unusual request, command or download proposals! See our tutorial on IRC here: IRC commands. Be polite and humble is the rule.
Tip: Be a bit patient at a start of a conversation as many users let the window open and work meanwhile on something else.

For the first visit in search of engineering support, we recommend connecting to Libera.chat or Freenode below.

IRCnet

Some of the rooms available on the IRCnet network: #engineering, #spaceengineers, #3DPrinting, #programming, #math, #science, #physics, #chemistry

DALnet

Some of the rooms available on the DALnet network: #html, #3dprinting, #High-tech, #aws, #robotics, #electronics, #math, #physics

EFnet

The oldest network, but possibly the less unified, as different local server instances may have different rules so as in EU or North America. We connect here via the Dalarnas Univerity (Sweden).
Some of the available rooms on the EFnet network: #engineering, #engineer, #3dprinting, #prototype, #openscad, #csmech, #science, #maths, #science, #autocad, #solidworks

Freenode

Freenode was initially created to host OpenSource projects in particular. It hosts a lot of channels related to technologies and engineering.
Some of the rooms available on the Freenode network: #engineering, #ee, #systemengineers, #design, #Designers, #opensourcedesign, #AltiumDesigner, #productivity, #openprinting, #3d-printers, #sprint, #3dprinter, #reprap, #arduino, #kicad, ##algorithms, #c, #programming, #hardware, ##mechanics, #MechanicAdvice, ##electronics, ##math, #science, ##neuroscience, ##chemistry, ##biochemistry, #astrophysics,#kicad,#freecad, ##openscad, #openscad, #librecad, #MechanicAdvice, #solidworks
Note: a double “#” usually means it is not the official channel compared to a single “#” … but if there is no official, then just another one on the same topic.

Libera.chat

Libera.chat is the youngest network but hosts the most active rooms of this page.
Some of the rooms available on the Libera.chat network: ##stm32, ##science, ##engineering, ##systemengineers, ##multirotors, #design, ##design, #reprap, #octoprint, #python, #C++, ##hardware, #windows, #php, #java, #arduino, ##electronics, ##perl, ##mechanics, ##electronics, ##electronics, #sparkfun, #hackvana, ##math, #algorithms, ##science, ##biology, #logic, ##programming, ##chemistry, ##physics, #kicad, #freecad, #openscad, #mechanicaladvice, #arduino
Note: a double “#” usually means it is not the official channel compared to a single “#” … but if there is no official, then just another one on the same topic.
