Paste69
This project has undergone several changes, but here's where we are now: Paste69 is a clone of the popular pastebin service 0x45.st, but written in Crystal using the Athena framework rather than in Python with Flask.
Differences from 0x0
I have tried to keep feature parody with 0x0, but there are some small differences:
- Multiple storage providers are supported (local and s3 for now)
- The configuration format is slightly different, as are some config items
Some features have also yet to be implemented. They will be coming in the near future. These features include:
- NSFW detection
- Virus scanning
Installation
Installation requires Crystal and Postgres. Other databases might be supported in the future.
Clone this repo:
git clone https://github.com/watzon/paste69
Install dependencies:
shards install
Copy and modify the config file:
cp config/config.example.yml config/config.yml
vim config/config.yml
Build the executables, migrate the database, and run the server:
shards build
./bin/cli db:migrate # this assumes the dabase exists, if not run db:create first
./bin/server
Using Docker
If you want, you can build the Docker container yourself locally:
docker build -v ./uploads:/app/uploads --tag paste69 ./docker
docker run -d -p 8080:8080 paste69
Or, you can use the hosted version available through ghcr:
docker pull ghcr.io/watzon/paste69:main
docker run -d -p 8080:8080 ghcr.io/watzon/paste69:main
All configuration items are available through environment variables, in addition to the config file. Configuration items and their environment variable names are listed below.
Configuration
I've done my best to make Paste69 as zero configuration as possible. The default values listed in src/services/config_manager.cr should be sufficient for most deployments. However, should you wish to change any of the values you can do so through a config file, or using environment variables.
Valid config file locations are:
- /etc/paste69/config.yml
- ~/.paste69/config.yml
- ~/.config/paste69/config.yml
The following table contains all available configuration options, their default values, and their environment variable counterparts:
| Config Item | Default Value | Environment Variable | Description |

Custom Templates
Paste69 supports custom templates, which can be used to override the default templates. To do this, simply create a directory somewhere and copy the default templates from src/templates into it. For example:
mkdir -p ~/.config/paste69/templates
cp -r ./src/templates ~/.config/paste69/templates
and then update your config file (or set the TEMPLATES_DIR environment variable) to point to the new location.

-templates_dir: "src/templates"
+templates_dir: "~/.config/paste69/templates"
this directory will be used in stead of the default templates, and not in addition to, so be sure to copy all of the templates over.
IP Blocklisting
IP blocklisting is supported. All uploads database entries should contain an IP address, telling you where it was uploaded from. If you want to block a certain IP address (or even an entire subnet), you can create a file containing a list of IP addresses to block and upadate your config file with the path to the file. The file should contain a single IP address or subnet per line. For example:
192.168.1.1
172.16.17.32/24
