Host a Python Discord Bot on AWS Lambda (Free and Easy)

Learn how to create and host a Python Discord bot on AWS Lambda.

In this tutorial, you'll learn how to create a Discord Bot using Discord's Interaction HTTP endpoints — and then host it for FREE on AWS Lambda. This is a super easy, cost-effective, and scalable way to host Discord bots.

We'll be using Flask and Python for the Discord bot, and AWS CDK to deploy our Lambda infrastructure.

I love how much easier it is to understand how to do all of this, thank you!

[sesameydmclips]

Thanks for the tutorial! I wanted to try using Lambda instead of hosting on EC2 this time, and this worked well

[menisadi]

Please please make a video about making of a Telegram bot!
I know that there are guides out there but your videos are just so clear that I think they add value even on topics which where already covered by others

[mozphat]

It took me way too many hours to FINALLY get commands to work. The registration part is not obvious. Thank you!

[volodymyrtruba]

Fantastic video! However, how do we handle logic that takes more than 3 seconds to execute, considering Discord messages have a 3-second limit?

[HashtagTiluda]

All the videos you publish are real gems. Not sure if you take requests but can you create a video on a full stack app creating with FastAPI/Supabase backend and NextJS frontend which would cover authentication, stripe billing, etc.

This is absolute gold! Really well presented, step by step!! New subscriber 💪 I wonder if you could do an extension of this example where the bot reacts to events that happen on the Discord server like a new user arriving at the server (from an invite link) to do something tricky - check if the email they registered their account on Discord matches the domain that I, the Discord bot owner, will define (it's actually to set a Role for users that belong to my company) 🤔

[Snred]

Great video! Regarding performance, e.g a decent amount of users using a lot of commands simultaneously, does AWS Lambda take care of that?

[danielegurizzan]

Hello! Thank you for the amazing tutorial, even a noob like me could understand everything. I need help with CDK, I successfully installed and set up CDK and CLI with credentials. When I run "cdk bootstrap" it fails because the "aws-cdk-lib" and "constructs" modules are not found, did I miss a step?

[ProGamingRV]

But this wouldn't work for events that expect a response, right? like modifying a message in a pool. Because it doesn't maintain the connection. And how do you keep bot from falling when the lamba goes cold?

[cat.dog]

Thank you for the good video. If I want to use the selenium library, how can I add a layer?

[bigbadbroadcast]

So I got all the way to the end, with deployment being successful and I got the link. However, when I check to see, my bot its still offline and also there is no function in aws. Does deploying create a function automatically?

Follow up question, when you created your bot it was listed as online, while when I made mine it is automatically offline. What did you do here to get it online?

EDIT

alright I followed the steps again and got it working, but I still don't see the lambda function in AWS, and I don't know how to debug any other way.

EDIT AGAIN

Found it in AWS, I was looking at the wrong region, still can't find a console to do debugging, was wondering exactly how I would test this locally

hi there i am facing this error : REGISTER REGISTER_COMMANDS.PY
'REGISTER' is not recognized as an internal or external command,
operable program or batch file. please try help

[parYTG]

I need help with what commands did you use for the command prompt? At 6:38

[gamersgame]

Hi just asking is this method better hosting than EC2 method

[saphirsatillo]

Thanks for the video. I have a question though, how do you unregister a command? I'm getting a 405 error when I try to request delete.

[bleakaddict]

Just wanna know if its a serverless hosting

[innerpeacetheskullcollector]

can i host javascript v14 bot with this?

[Rohitnansen]

When I attempt to create a bot in discord, it shows as offline instead of online in my server as it is for you. Anyone know the approach to turn it on?
