How to start the BOT?


After downloading, extract the zip file and navigate to that location in your terminal. There will be a file named wbot-* . Run it and you should be good to go.

For Linux you need to provide executable permission before you execute the binary. Run the command –

chmod +x wbot-linux && wbot-linux

Note: on Linux you need a running display server (X11 or Wayland). If you run Linux on a headless server or wan’t to run chmomium without visible display try xvfb-run wbot-linux.

I haven’t tested Mac and Linux binaries. If you find any issues using them feel free to raise one from here


Basic configuration is in bot.json file like replying to Hi, hello and happy birthday. You can add/remove yours if you need. Keep in mind that you need to restart the wbot to see the effects of your changes. Make sure the JSON is valid. Use VSCode or jsonlint to validate the JSON.



This is where all the application related (node application behavior and such things) config will stay. Will add more in future.

  • headless whether to start chrome as headless or not. this is regarding #4. Apparently, Whatsapp doesn’t allow headless instances.
  • isGroupReply whether to send replies in group or not. If set to false, Bot will not reply if message received in group chat.


An array of objects. Properties of Object are self explanatory.

  • Contains If message has one of that word anywhere in the message
  • exact If message is exactly as one of the messages form array
  • Response If any of the above conditions becomes true then corresponding response string or spintax will be sent as message to the user or group.
  • file name of the file (from current directory) which you want to send along with response


Array of numbers with county code to which this bot will not reply to.


Default reply message or spintax when no exact match found in BOT

smartreply (This feature is under maintenance at the moment.)

An object which contains suggestions and it’s configs.

  • suggestions An Array of suggestions
  • clicktosend Whether to send or just write message when user clicks on suggestion

here is how that looks

Run the latest code from github

This is only recommended for advanced ‘node.js’ users.

open a Terminal and create a new directory in your home directory, e.g. ‘node’ and goto there. Now download and run the latest code from github by:

git clone https://github.com/vasani-arpit/WBOT.git
npm install
node src/index.js

If you run Linux on a headless server or wan’t to run chmomium without visible display try xvfb-run wbot-linux.

Known bugs

Sometimes, closing the node server directly does not clear browser cache. Next time when the bot is started, it runs into errors due to which smart reply is not setup correctly. A temporary fix to this is to clear node cache.

npm cache clean



The main reason I decided to build this is that I needed a simple tool to reply to my “happy birthday” messages. I know it is kind of blunt and rude but it would take me 2-3 days to reply to all and by that time that moment would be gone. I needed a good solution to this problem. I really don’t need a full-fledged AI-BOT or BOT with NLU (or some other acronym). I believe there are many people who also have such needs.


With that in mind, I know that WBOT would need to satisfy these criteria:

  • 🚀 Fast!!!
  • 👍 Friendly CLI UX
  • 🔒 Does not touch user’s data
  • 💰 Free! for personal use

If you think WBOT delivers these, let me know by putting a star ⭐ on this project

  • What npm modules did you use?
  • Apart from development, What else do you do?I do motion design and UI/UX development.
  • Are you available for hire?I have a full-time job as a software developer at technobrains.net and at mindtechconsultancy.com. I am available as a freelance consultant during my spare time please let me know what you have in mind.
  • How do I contact you?If you find an issue, please report it here. For everything else, please drop me a line at vasani.arpit@gmail.com
  • Do you have any other projects?I thought you’d never ask. Yes, I do. SMA is one of them.
