This is an LTS release so it will be&#supported for some time to come. This will not...

   tl;dr We recently started validating that the postal codes used for paid PythonAnywhere accounts match the ones that people’s banks have on file for the card used. This has led to some confusion, in particular because banks handle postal code validation in a complicated way - charges that fail...

Playwright is a browser automation framework that was developed by Microsoft; like the more-established Selenium it’s really useful for testing and web-scraping, and it’s getting a reputation for being a...

   tl;dr We have a number of background processes that execute periodically on our systems; one of these is the one that resets the amount of CPU used, so that you get a fresh allowance every day. Early in the morning of 2024-05-03, on our US-hosted system, that service failed silently. Unfortunately,...

   AI is the coolest thing in tech right now, but getting an AI-powered website up and running can seem pretty daunting. Luckily, there are a bunch of useful tools to make it easier. A while back we started seeing if we could use large language models to provide a helpful assistant for PythonAnywhere;...

   tl;dr On 2023-10-09 we had an unplanned outage. While we were preparing our systems for a scheduled system update the following morning, we faced some issues. These in themselves would not have caused problems, but responding to them resulted in the accidental termination of the old, running...

We have some plans on...

   Scary times. We hope everyone reading this is well and keeping safe We thought it would be a good idea to tell you how we’re managing the current crisis at PythonAnywhere. We switched over to remote working last Thursday, 12 March; there are obviously private and public health reasons why that was...

   One of the challenges of remote work is when you need to work together on one thing. Our in-browser consoles are one of the core features of our service. Almost since the beginning, PythonAnywhere has been able to share consoles - you entered the name of another user or an email address, and they...

   On 3 March we upgraded our EU-based system at eu.pythonanywhere.com to the latest version of our code, and this morning (5 March) we upgraded our US-based system at www.pythonanywhere.com to the same version.

   If you signed up since 26 November, you’ll have Python 3.8 available on your account - you can use it just like any other Python version. If you signed up before then, it’s a little more complicated, because adding Python 3.8 to your account requires changing your system image.

   This morning’s system update went smoothly; some websites did take a bit longer than we expected to start up afterwards, but all is well now. There are two big new features that we have introduced which are going through some final post-deploy tests before they go live - a new system image (called...

   In brief: if you have an account on www.pythonanywhere.com you can have it migrated to eu.pythonanywhere.com - just let us know via email to support pythonanywhere.com. If you’d like to know more about what that means, read on...

   We received many requests from PythonAnywhere users to make it possible to programmatically monitor&#usage of CPU credit, so we decided to add a new endpoint to our&#experimental API.

   Our API supports lots of common&#PythonAnywhere operations, like creating and managing consoles, scheduled and&#always-on tasks, and websites. We recently added support for reading writing&#files; this blog post gives a brief overview of how you can use it to do that.

   Our system update on 26 June went pretty smoothly :-) There were a number of useful changes: Our API now supports uploading, downloading and listing files in your private file storage.

   Always-on tasks are a new feature we rolled out in our last system update. Essentially, they’re a way you can specify a program and tell us that you want us to keep it running all the time. If it exits for any reason, we’ll automatically restart it - and even in extreme circumstances, for instance...

   Always-On Tasks We are officially live with our always-on tasks All paying customers will get one always-on task, and you can add more by customizing your plan on our accounts page. Our infrastructure will try to keep your script always running (ie. we will restart it if your script errors and...
