The Null Pointer

This is a no-bullshit file hosting and URL shortening service that also runs envs.sh. Use with uWSGI.

If you are running nginx, you should use the X-Accel-Redirect header. To make it work, include this in your nginx config’s server block:

location /up {

where /up is whatever you’ve configured as FHOST_STORAGE_PATH in fhost.py.

For all other servers, set FHOST_USE_X_ACCEL_REDIRECT to False and USE_X_SENDFILE to True, assuming your server supports this. Otherwise, Flask will serve the file with chunked encoding, which sucks and should be avoided at all costs.

To make files expire, simply create a cronjob that runs cleanup.py every now and then.

Before running the service for the first time, run ./fhost.py db upgrade.

NSFW Detection

0x0 supports classification of NSFW content via Yahoo’s open_nsfw Caffe neural network model. This works for images and video files and requires the following:

  • Caffe Python module (built for Python 3)
  • ffmpegthumbnailer executable in $PATH


apt update
apt install python3-pip nginx uwsgi uwsgi-plugin-python3 certbot
git clone https://github.com/envs-net/0x0.git /srv/0x0

cd /srv/0x0
pip3 install --user `cat requirements.txt`
./fhost.py db upgrade


What about file management? Will I be able to register an account at some point?
Why are you storing IP addresses with each uploaded file?
This is done to make dealing with legal claims and accidental uploads easier, e.g. when a user requests removal of all text files uploaded from a certain address within a given time frame (it happens).
Do you accept donations?
Only if you insist. I’ve spent very little time and effort on this service and I don’t feel like I should be taking money for it.
