Quick Start

pip install zerodep          # install the CLI
zerodep add yaml retry       # copy modules into your project

from yaml import load, dump

data = load("name: Alice\nage: 30")
print(data)  # {'name': 'Alice', 'age': 30}

Each module is a self-contained single .py file — copy it into your project and import. No pip install needed at runtime.

Modules

Modules span Agent Protocols, Web & Networking, Data Formats, Data Validation, Text & Markup, Search & Retrieval, Configuration, CLI & Terminal, Security, and Infrastructure & Tools.

See the full module list for details, versions, and benchmarks.

Versioning

Project: CalVer YYYY.M.D (e.g., 2026.4.15)
Modules: independent SemVer per module (e.g., 0.4.1)

Releases are automated via the Release workflow — lint, test, bump module versions, tag, and create a GitHub Release in one step.
