The PythonAnywhere help pages
Many of your questions about PythonAnywhere are likely to be answered below. If
not, the best place to get support is in
our Forums and
EU Forums. We monitor them to make
sure that every question gets answered, and you get the added benefit that
other PythonAnywhere customers can help you out too. They're also a nice place
for a chat 
If you want, you can access an even broader group of people by asking your questions on StackOverflow; we check all posts there tagged with pythonanywhere daily, and reply if no-one else has already solved the problem.
But if you want to ask your questions in private and get responses over email, you can use the "Send feedback" link at the top of any page on PythonAnywhere. We'll be alerted and will get back to you ASAP. You can also email us directly via support@pythonanywhere.com
If you want help about Python programming generally (as opposed to PythonAnywhere), you can buy 1:1 live Python help at Codementor.
We also have a page that lists books and courses the people have recommended to us here.
The help pages below have the following sections -- hopefully you can jump straight to one that describes what you're looking for help with!

I'm looking at an error message in a console¶
Oh no! Here's our most common explanations and solutions to console problems:
- I get "permission denied" when trying to pip install a new module

Some technical problems with consoles that sometimes come up:
- I can't see what I'm typing in the console
- The "Starting encrypted connection" message never disappears
I'm looking at an error message in my web app¶
If you haven't already, the first step is to look in your error log -- you'll find a link to it on the Web tab (account in US servers; account in EU servers). There's more information about the error log here.
Once you've done that, here are some solutions to common problems
- Debugging import errors and sys.path issues <-- if you've just started setting up your app, chances are the answer is in here.
- Dealing with "there was an error reloading your web app" messages
- I'm getting a 502 Bad Gateway error. How can I debug?
- I'm getting a 400 Bad Request error from my Django app

I'm trying to figure out how to get a particular tool or feature to work¶
PythonAnywhere already has many of the Python modules that you might want to use installed. There is a complete list of them available on our Batteries included page
Here are some guides for some of the common things people want to do:
- Installing new Python modules for yourself
- Changing your system image
- Always-on tasks: how do I keep a console running forever? Or, how do I make a program that restarts automatically?
- How to I run an async task queue like celery?
- Can I use matplotlib to generate graphs from my data?
- Can I use SMTP to send email on a Free account?
- How do I solve authentication errors from Gmail when sending emails from my code?
- How to force HTTPS on your web app
- Using MySQL (including using MySQL with Python 3)
- Backing up (and restoring) MySQL databases using mysqldump
- Setting the timezone for your code
- Working with PDFs and converting document formats
- Can I use IPv6?
- Can I use Pygame / Tkinter / turtle / GUI packages?
- Using Selenium
- Using Playwright
- Does PythonAnywhere have an API?
- What do I do if a server I want to connect to has an allowlist that only allows incoming connections from particular (static) IPs?
- How to I get Twilio to work?
- Machine learning: what to do if your website using Keras, TensorFlow or PyTorch doesn't work
- Fonts
- Using Cloudflare with PythonAnywhere
- Installing TA-Lib on PythonAnywhere
- Using conda
And here's some very brief FAQ answers about common requests:
- Can I use MongoDB? It's not built in, but from a paid account you can use an external service like mLab. Some extra hints and tips on using Mongo here.
- Can I use an external MySQL service? Probably not (on a free account), unless they have an HTTP api.
- Can I use Redis? Again, only via an external service like redislabs. Although you can use redislite
- Can I use websockets, or run my own socket server? I'm afraid not -- we only support Python apps that implement the WSGI protocol
- How do I reload my webapp automatically? You can now use our API for this :)
- Which Python versions does PythonAnywhere support?
