Plash

What is Plash

Plash is a next-generation deployment platform for fast, hassle-free Python application hosting. It’s designed to be:

• Simple and streamlined - deploy your applications with minimal configuration
• Developer-focused - built for coders, not cloud engineers
• Fast and efficient - get your app online in seconds, not days

Plash handles all the deployment complexities so you can focus on what matters: building great applications. With Plash, you can deploy any Python app using straightforward commands and configurations, letting you ship your work quickly and reliably.

Whether you’re building web services, APIs, data applications, or tools, Plash provides the infrastructure backbone so you can concentrate on creating a splash with your code.

Tutorial: deploy your first app

In this tutorial you will learn how to deploy your first app. This tutorial will explore the basics of using Plash and help you get familiar with it at a high level.

Prerequisites:

• A registered account at https://pla.sh
• Basic terminal / command line skills

1. Installation

Install Plash comandline interface (CLI) with pip:

pip install plash-cli

The CLI lets you manage your whole app’s lifecycle

2. CLI Login

Authenticate with your Plash account:

plash-login

This command opens your browser to authenticate with your Plash account. After completing the login process, you’ll see a “complete” confirmation page in your browser.

Return to your terminal where you’ll find the confirmation message:

Authentication successful! Config saved to /plash_config.json

Alternative Authentication Methods

If you’ve already logged in on one machine and want to authenticate on another without opening a browser, you can transfer your authentication token directly. Run plash-login --show on the machine where you’re already logged in to print your current token. You can then copy this and use plash-login --token <your-token> on the new machine to authenticate.

For convenience, you can pipe the token directly to your clipboard. On macOS, use plash-login --show | pbcopy. On Linux with X11, use plash-login --show | xclip -selection clipboard or plash-login --show | xsel --clipboard. On Windows PowerShell, use plash-login --show | Set-Clipboard.

For automated environments like CI/CD pipelines or scripts, you can set the PLASH_TOKEN environment variable instead of storing credentials in a config file. When this variable is set, the CLI will use it automatically without requiring plash-login. For example: export PLASH_TOKEN="your-authentication-token" on Unix-like systems, or $env:PLASH_TOKEN="your-authentication-token" in PowerShell.

3. Create your first app

Create a new directory for your first app:

%%bash
mkdir -p plash-tutorial
cd plash-tutorial

Next, create the main.py file:

%%writefile main.py
from fasthtml.common import *

app, rt = fast_app()

@rt
def index():
    return H1("Hello, world!")

serve()

This is a basic FastHTML app. Plash also supports other popular python frameworks.

And create the requirements.txt file:

%%writefile requirements.txt
python-fasthtml

4. Deploy your app

Now that you’ve created your app files, you’re ready to deploy! From your plash-tutorial directory, run: plash-deploy

This command will:

1. Package your application files
2. Upload them to Plash’s servers
3. Build and deploy your application

%%bash
plash-deploy

Initializing deployment...
✅ Upload complete! Your app is currently being built.
It will be live at https://example-app.pla.sh

Note: You’ll see a different url that has been randomly generated for your app.

5. View your app

Your app should be ready a couple of seconds after running the deploy command.

Once your app is ready, you can:

1. Open the provided URL in your browser, or
2. Use the convenient plash-view command to open it automatically:

plash-view

When you visit that page you should see “Hello, World!”

🎉 Congratulations! You deployed your first app on Plash!
