Hosting discord.py bots on repl.it
This tutorial shows you how you can host your discord.py bots on repl.it.
For Node.js see this tutorial.
Just to ease things, we'll be using the end product of this tutorial.
Here is the end result: https://repl.it/@TheDrone7/discordpy-rewrite
What we'll be doing?
Creating a web server.
Using uptimerobot to ping our bot every 30 minutes.
We do this because our repl goes offline after 1 hour of inactivity. So we keep pinging the repl every 30 minutes, to avoid it being idle for one hour.
Step 1: Installing the dependencies.
Using the repl.it package manager, install the following dependencies (assuming you've already made the bot,
discord.py would be installed already but is listed just in case): -
In case you don't know about the repl.it package manager, click here to get started with the repl.it editor.
Step 2: Setting up a server
Setting up a server using Flask is very easy. But to keep things simple and your bot's file clean, we'll make a server in a new file and name it
keep_alive.py since that is what most people like to call the file that helps keep their bot alive.
Open up the
keep_alive.py file and import
Flask also import
Thread you can learn more about Threads here.
from flask import Flask from threading import Thread
We didn't have to add threading to our requirements since it comes with python.
Next, create the actual server.
app = Flask('')
Easy, isn't it? But it's not over just yet.
Next, we add a route. A route is basically what handles http requests. Without a route the existence of our server does nothing. So add the following code
@app.route('/') def main(): return "Your bot is alive!"
@app.route() is a decorator which defines a route.
'/' is the default route or the homepage of our server. The
main function is called whenever a user makes a request to the
'/' route which basically returns whatever has to displayed on the webpage, here we simply send the string
Your bot is alive to keep things simple.
Now that our server is ready, we need to make sure that it runs and http requests can be made to it.
def run(): app.run(host="0.0.0.0", port=8080)
You can basically put any 4 digit number in port which is not already in use. The defaults for python is
8080 and that's what we'll stick to.
Finally, we make a function that we can call to prepare our server and allow it to be pinged.
def keep_alive(): server = Thread(target=run) server.start()
And we're basically done with our
Step 3: Combining the server and bot.
Now that we're done making both the bot and the server, we need to combine the two. That is easy too, open up the
main.py file ( or whatever file has the
discord_client.run(bot_token) function in it ) and add the following line at the top: -
This will import the keep_alive file in your bot's main file.
Now just before starting the bot, at the bottom of the same file write the following code: -
This will run the
keep_alive() function that we defined in the
keep_alive.py file earlier.
And now your server is ready too! Run the bot, you should see something like this: -
Notice that small window saying
Your bot is alive! if you see it, you successfully created the server! Only the last step remains! Before you go into the last step, make sure to copy the
repl.co link you see in that small window's address bar. (
https://discordpy-rewrite.thedrone7.repl.co in the picture, it will be referred to as the
server link in the rest of the tutorial)
And in case you don't see it, go through this tutorial again and make sure you didn't miss something, also if it retains, don't hesitate to comment and tell me.
Step 4: Setting up uptimerobot
First of all visit https://uptimerobot.com/ and register an account just like any other website. (It is free of course)
Next, Once, you're logged in,
Next, choose the
Give it a friendly name of your choice ( naming it after your bot is recommended )
server linkin the
Set the Monitoring Interval to anything between 5 minutes to 45 minutes. ( 30 minutes is recommended)
Create Monitorand you're good to go!
Now you're bot will stay online for as long as it can.
( Repl it being just another host, won't be able to host it 24/7 so it will have a downtime of a few minutes within every 24 hours.)
And you're done! The final product can be found here.

Good job! Now the pressure is on for me to finish my discord bot tutorial... Well, I can just copy and paste this at the bottom :D
This worked great for one of my bots, thanks! It has been up for ages without issues. However, I recently made another bot and this one crashes every couple of hours. No errors, it just stops running. I have exactly the same setup with keep_alive, the only difference being that this bot uses cogs. Any help would be greatly appreciated, thanks.
cannot add package. I know it doesn't add it in the package menu. there's nothing in it even i specified discord.py in requirements.txt. Manually adding it does not work either.
I guess the package manager might be having some issues then. I'm glad you figured out a workaround. Also, if you see "bot is alive" and the bot isn't online, the bot probably had a bug that crashed it. I'd recommend temporarily getting rid of the server and debugging the bot. @windowsboy111
This looks SOOO much like https://www.codementor.io/garethdwyer/building-a-discord-bot-with-python-and-repl-it-miblcwejz
I added everything as you said, but when I ran the file I didn't get any debug message on the console, and the app is not running when I close the tab. How can I fix this?
