MistLock

Catalog of automated Cloud dev environments. No accounts, local-first and compatible with AWS, Azure and GCP.

🐳

Dockerized

Each environment is isolated, reproducible and self-contained using Docker. No dependency conflicts on your local machine.

🧩

Dev Containers

Configure the full environment just by opening the project in your IDE. Everything is ready to go from the first keystroke.

💸

Free & No Accounts

No AWS, Azure, Google Cloud or any other provider accounts are needed. No credit card. Zero infrastructure costs.

☁️

100% Compatible

Code you develop locally works exactly the same on real Cloud providers. No changes needed. Develop locally and deploy when you are ready.

🔀

One Goal, Multiple Methods

Every Lab supports multiple ways to run, debug and test, and many visual tools and extensions to manage local resources.

Labs

We call each catalog example a Lab, and there are two types of Labs: MVE (Minimal Viable Examples) and Projects.

MVE

A Minimal Viable Example focuses on a single Cloud service: how to emulate it and what tools to use. There can be more than one MVE per service if multiple emulation options are available.

Project

Combines multiple Cloud services in the same local environment to show how they integrate in a real workflow.

How it works

1

Select a Lab from the catalog.
2

Download the code.
3

Open it in your IDE.
4

Execute it in one click.

You can execute the Lab with Dev Containers and without it.

With Dev Container

# Open in Dev Containers

# Run the lab
python main.py

Without Dev Containers

# Start the infrastructure
docker compose up -d

# Setup up the environment
./scripts/setup.sh

# Run the lab
python main.py
