# mozilla-taskgraph — Mozilla specific transforms and utilities for Taskgraph

License: copyleft · Maintenance: active · Downloads: 807.1K/mo

## What it is and what it does

mozilla-taskgraph is a specialized extension layer for Taskgraph that encodes Mozilla's specific conventions and transforms for build and release automation. It sits on top of taskcluster-taskgraph, the core task-graph library, and adds Mozilla-specific logic for defining and orchestrating CI/CD tasks.

The package is actively maintained and supports modern Python versions (3.9 through 3.14). It carries a copyleft license (MPL 2.0), meaning any modifications must be shared under the same terms. With low install friction and no known vulnerabilities, it integrates cleanly into environments already using Taskgraph for task orchestration.

Use it for:

- Extend Taskgraph with Mozilla-specific build and release automation transforms.
- Configure CI/CD pipelines using Mozilla's established conventions and task definitions.
- Integrate Mozilla releng utilities into custom Taskgraph-based automation workflows.
- Build task graphs that follow Mozilla's release engineering standards and patterns.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Mozilla-specific transforms and utilities for Taskgraph, extending the taskcluster-taskgraph library with Mozilla's build and release automation conventions.

Yes, if you are building or extending Mozilla's CI/CD infrastructure or need to integrate with Mozilla's Taskgraph conventions. The package is actively maintained, has no security vulnerabilities, and integrates cleanly. The copyleft license is standard for Mozilla projects and poses no barrier to use or internal modification. Not relevant for general-purpose task scheduling outside Mozilla's ecosystem.

## Install

pip install mozilla-taskgraph
uv add mozilla-taskgraph
poetry add mozilla-taskgraph

## Installing mozilla-taskgraph

Before you install: Low install friction with a pure-Python wheel. Actively maintained with a release 7 days old and recent commits. Supports current Python versions (3.9 through 3.14).

License in practice: Licensed under Mozilla Public License 2.0 (MPL 2.0), a copyleft license. Code modifications must be shared under the same license, and derivative works require source disclosure.

Quickstart:

pip install mozilla-taskgraph

from mozilla_taskgraph import transforms
# Use Mozilla-specific taskgraph transforms

Requires Python 3.9 or later. Depends on taskcluster-taskgraph runtime library.

Verify before relying:

- What specific transforms or utilities does mozilla-taskgraph provide beyond taskcluster-taskgraph?
- Is this package intended for Mozilla internal use or general CI/CD automation?
