We launched serverless hosting option for Flask apps
Hey r/flask ,
I’ve been deploying Flask and Django apps for years, and one thing that always frustrated me is the cost—especially for small projects that don’t get much traffic.
# The problem:
Paying for idle time – Most hosting providers charge 24/7, even if your app is mostly idle.
Multiple apps, multiple bills – Want to run a few small services? You’ll likely pay for each one separately, even if they barely get used.
I wanted a more efficient way to host Flask apps, so I built Leapcell—a serverless option that deploys instantly, gives you a URL, and only charges for actual usage (no idle costs).
If you’ve struggled with the cost of Python hosting, I’d love to hear your feedback!

Ascii Video Player
Hello People!
A few months ago, I built an ASCII video player that converts any video into an ASCII art version (with audio support). Back then, I didn’t have the confidence to share it, but now I’ve decided to put it out there!
What My Project Does
ASCII-Flix lets you watch videos directly in your terminal by converting frames into ASCII characters, creating a retro, text-based viewing experience. It supports 2 modes for different ASCII rendering styles and plays the original audio alongside the video.
I used OpenCV, python-curses, and Pygame(for audio support) .
Target Audience:
This project is for anyone who enjoys creative terminal-based projects, ASCII art enthusiasts, and people who like experimenting with unconventional ways of watching videos. If you’re into tech nostalgia, retro computing aesthetics, or just want to try something fun in your terminal, you’ll probably enjoy this!
Comparison:
This was inspired by ASCII Theatre, which allows you to watch movies in ASCII art format in the terminal. However, ASCII Theatre is a more refined version of this concept. ASCII-Flix, on the other hand, is something I made for fun—it’s a lighthearted experiment that brings a unique way to experience videos in ASCII form.
How to use it:
1. pip install ascii-flix
2. Type the command ascii-flix on your

The best CI/CD strategy with Django App
Hi everyone! I've launched the personal project based on django and untill the last moment, after some updates I just log in to the server and update everything on my own via ftp, and then just restart gunicorn, which was fine until now. Since it starts being hard to manage project in such a way, there is a need to implement CI/CD for it, so i would really like to get an advise from expirienced (or who has dealt with it at least) developers, what are the best steps to do that without Docker (in case of Docker everything is kinda clear), but with Git for sure
The questions ISN'T about certain CI/CD tool or piece of code, but just about strategy. I definitely reffered to SO, but it's all about specific issues with particular pieces of advise.
Ideally, i would like to see the following: there is a stable version (should it be another branch or just a generated folder with timestamp? - also the question), there is a new version with features - I deliver it with job to the server and if everything is ok - mark it as stable, if it's not - to rollback to previous one.

Keeping Azure Blob synchronised with Django Database
This is the Image Model for a Gallery app. I realised that the default behaviour of django-storages is that it uploads files to AzureBlob but doesn't delete the files when the database entry is deleted. Not sure if this is the way to do it? It seems like it should be really common but I've had to dig up the AzureBlob SDK manually to do it. I also have a thumbnail function for faster loading (will change some parameters later)
class Image(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=255)
description = models.TextField()
image_file = models.ImageField(upload_to='images/')
thumbnail_file = models.URLField(null=True, blank=True) # Store Azure URL instead of ImageField

blob-path: pathlib-like cloud agnostic object storage library
# What My Project Does
Having worked with applications which run on multiple clouds and on-premise systems, I’ve been developing a library which abstracts away some common functionalities, while being close to the pathlib interface
tutorial notebook
Example snippet
from blob_path.backends.s3 import S3BlobPath
from pathlib import PurePath
bucket_name = "my-bucket"
object_key = PurePath(
"hello_world.txt"
)
region = "us-east-1"
blob_path = S3BlobPath(
bucket_name,
region,
object_key,
)
# check if the file exists
print(blob_path.exists())
# read the file
with blob_path.open("rb") as f:
# a file handle is returned here, just like `open`
print(f.read())
destination = AzureBlobPath(
"my-blob-store",
"testcontainer",
PurePath("copied_from") / "s3.txt"
)

UV or PyEnv for student python teaching / python installs (linux)
I teach python across a number of courses (primarily on linux) from 1st year just learning to program to MSc Level Machine learning.
For the last few years I have used pyenv to manage the python versions the students are using, either as a pyenv global for a specific version of python for the 1st years. To using pyenv for anaconda install for the MSc students.
I have not really used virtual envs with the students as it adds a lot of complexity to the students learning and they tend not te be very good at tidying up etc.
I'm thinking of moving to uv but as it doesn't quite work like pyenv I'm not sure how to manage the students python installs.
My initial idea is to write a script to install uv and then install the required python version and then install the required default packages (numpy etc etc) and generate a default root / home level venv and make this transparent to the students so basically when they login they are in a venv with everything they need.
Pros to this is the students just run python and it works which for the 1st years is a big win.

13 Months into Django - Built a Boilerplate to Share
I started learning Django 13 months ago and I really enjoy it. I've been building web apps and improving my skills ever since.
The more I built, the more I noticed setup was eating my time: auth, payments, same old grind.
So I put together a little boilerplate to skip the hassle - Django with HTMX, Tailwind + Kutty, Stripe, Wagtail, Django-Allauth all ready in 15 minutes.
It’s been a time-saver for me, and a couple friends didn’t hate it. Figured I’d share with the community that got me started.

Need help with authentication
I am currently working on a project with django rest api and react js. I am confused in selecting a proper authentication method. It's a small internal web based app that would only be used within the company and targeting less than 60 users.
Should I go for jwt based authentication or try to implement session based authentication. Even though I have experience in the backend Development, I am used to code in jwt based authentication since we had a react native based app.
Does jwt have any security issues?
If session authentication is better how can I make it work with react js. I remember trying this few years back and cookies were not working when on different domains. I am planning to dockerize entire thing. Will the session work properly then?
Nb: I have been working on spring boot project for few years. My first few years was with django. Returning to django now.

I didn't want to go, but PyCharm finally drove me into the arms of VSCode, after 5+ years.
I just switched to VSCode after well over five years with PyCharm. I didn't want to do it, but I just can't stand it anymore.
Things I love about PyCharm and will miss
1. The refactoring functionality. VSCode's Python extension has that too, but it isn't as nice.
At this point, that's pretty much it.
Things that drove me nuts
1. IdeaVim. It actually got better recently, but for years and years, the undo function was busted, so you had to hit u over and over to undo what in real vim is a single operation. VSCode's neovim plugin uses actual neovim under the hood, which is obviously so much more robust and faithful, while IdeaVim will never be a full implementation.
2. The gradual accumulation of simple bugs that never get fixed.
3. It's so slow. I didn't appreciate just how slow until I switched over to VSCode. I mean, holy crap, it's 10x faster for a lot of things (opening a project, installing or restarting extensions, for example).
Here are the bugs that have bugged me the worst:
The "usages" window (cmd-click on a definition, see where it's used) constantly resizes itself too small. It's been a problem for years. They won't fix the way autosize

Turtle.py app to demo RGB color values
* What My Project Does
I've been working on turtle-related projects and I needed a simple, interactive, single-file Python program to explain RGB color values. I wrote this one up as part of my work writing [a Simple Turtle Tutorial written in Wikipedia-style Simple English](https://github.com/asweigart/simple-turtle-tutorial-for-python/) so it can be translated to non-English languages.
The app has three sliders for the amount of red, blue, and green for the window's background color. The RGB values are presented under the sliders for the 0.0 to 1.0 scale, 0 to 255 scale, and hexadecimal 0x00 to 0xFF scale. You can drag the sliders or click on the slider lines directly. There are also 14 preset color buttons along the top to click on.
PyPI page: https://pypi.org/project/turtlecolors/
GitHub repo: https://github.com/asweigart/turtlecolors
Install with `python -m pip install turtlecolors` on Windows or `python3 -m pip install turtlecolors` on macOS/Linux.
Run with `python -m turtlecolors` on Windows or `python3 -m turtlecolors` on macOS/Linux. Or run the code `import turtlecolors;turtlecolors.main()`
When the program first runs, it also prints out the color name strings that Python's turtle module uses. Unlike other lists of color names, I actually checked my list against the turtle.py to make sure they're correct. (I'm pretty sure clickbait articles just use chatgpt

I built a simple Terminal UI for pytest, feedback welcome!
# What My Project Does
I missed an easy, simple and quick way to run pytests in the terminal.
Link to project: https://github.com/0-sv/pytesttui.
My project lets you run `pytesttui` in your terminal. After opening, it shows you a tree of all your tests in the tests directory. Still in an early stage, so all it does is if you hit "r" and selected your test, it will run it. It scaled in the repository I use at work which contains about 500 tests. It is more efficient than running it in an IDE because it runs instantly, which is why I like terminal UIs.
If you'd like to try it and you have a Macbook, then visit my github page and download the release. Extract the files and place it in a PATH location like \~/.local/bin. You will probaby have to accept a security warning by MacOS, which is done by browsing to the "Privacy & Security" tab in settings and clicking on "Allow anyway" after running it. Make sure `pytest` is also accessible in a PATH location or installed using pip.

What are the best linters and language servers for python?
I am confused at the different language servers, linters, and formatters available. Here is what I have been able to figure out, is this correct?
Ruff is a linter / code formatter. It has overtaken Black and Flake8 as the best / most popular. Rust.\
\
JEDI is a library (~~but not a language server?~~) that supports autocompletion, goto, and refactoring.
Pyright is a language server maintained by Microsoft. It supports type checking, goto, autocomplete, similar to JEDI. It is written in TypeScript. I think Pylance is technically the language server and Pyright is the type checker (??)
MyPy is also a language server. It is considered slower and less fully featured than Pyright. It is used primarily because it supports plugins, such as for Pydantic and Django. It was started in 2012 and is written in Python.\
\
PyLSP/Python LSP Server is another language server but it requires another implementation such as JEDI to work. I am not sure what the advantages/disadvantages of it are.\
\
Some commercial IDEs like PyCharm use their own linters and type checkers.\
\
I use the Helix editor and by default it will use Ruff, JEDI, and pylsp together. While it works great,

Launched a hosting platform optimized for Django deployment
Hey, I'm Isaac. I've been deploying Django apps for years, and one thing that always annoyed me is how expensive it is—especially if you have multiple small projects.
The problem:
1. Paying for idle time – Most hosting options charge you 24/7, even though your app is idle most of the time.
2. Multiple apps, multiple bills – Want to deploy more than one Django service? Get ready to pay for each, even if they get minimal traffic.
I built Leapcell to fix this. It lets you deploy Django apps instantly, get a URL, and only pay for actual usage. No more idle costs.

At what point is HTMx not going to suffice for large ERP?
I'm starting a new project that will be large with lots of moving parts, complex modules, and different spaces for different users. Its an ERP, so you can imagine the types of data and functionality I will be building.
For past large projects, I have always used Django DRF as an API backend and a VueJS frontend to consume the API. This has worked well in the past, providing a rich user interface and experience. However, it always comes at the cost of overall project complexity given that there are two separate code bases to manage.
So, instead of DRF + VueJS I'm considering Django templates + HTMx. I've worked with HTMx in the past, but not extensively. I've also always heard the phrase "unless you're building a spreadsheet type app, HTMx will be fine". OK - but, I might need some of that level of complexity given that I'm building an ERP. I just don't want to get into Django + HTMx and realize 6 months down the road, HTMx isn't going to cut it.
My question is - have any of you built really large projects with complex UI/UX and only used the Django templates + HTMx? Can
