Openwork Project License: Understanding the MIT and Fair Source Dual-Licensing Model

The Openwork project uses a mixed-license model where the core codebase is governed by the permissive MIT License, while the enterprise-only code in the /ee directory falls under the more restrictive Fair Source License.

The different-ai/openwork repository employs a sophisticated dual-licensing approach to balance open-source accessibility with commercial sustainability. Understanding the Openwork project license structure is essential for contributors, integrators, and enterprise users evaluating the codebase for production deployment.

Mixed-License Model Overview

The repository implements a clear hierarchy of licenses depending on which directory you are working in. According to the source code analysis, the project explicitly separates open-source components from commercial features through directory-based licensing.

Core Repository: MIT License

All files outside the /ee directory and other third-party folders are licensed under the MIT License. This permissive, BSD-style license allows free use, modification, distribution, and private or commercial exploitation, provided the copyright notice and permission notice are retained. The full license text resides in the top-level LICENSE file at the repository root.

Enterprise Edition: Fair Source License

The /ee directory contains enterprise-only code governed by the Fair Source License. This license grants source-code access but limits commercial use without a paid subscription, creating a clear legal boundary between community and commercial functionality.

Third-Party Components

Dependencies and third-party components maintain their original upstream licenses (e.g., Apache-2.0, BSD-3). These are cataloged in the NOTICE file at the repository root, ensuring compliance with upstream requirements.

Key License Files and Their Locations

Several critical files define the legal framework of the project:

• LICENSE – Contains the MIT license text for the majority of the codebase and explains the mixed-license model.
• ee/LICENSE – Houses the Fair Source License governing the enterprise directory.
• NOTICE – Lists third-party components and their respective upstream licenses.
• package.json – Declares the project's open-source nature and points to the license file for npm tooling compatibility.

Working with License Information Programmatically

You can access license metadata at runtime or display compliance information in documentation.

Reading the License at Runtime

When building tooling or admin dashboards around Openwork, you may need to verify the license text programmatically:

import { readFileSync } from 'fs';
import { resolve } from 'path';

// Resolve the repository root at runtime (adjust if packaged)
const repoRoot = resolve(import.meta.url, '..', '..');
const licensePath = resolve(repoRoot, 'LICENSE');

const licenseText = readFileSync(licensePath, 'utf8');
console.log('OpenWork License Summary:\n', licenseText.split('\n')[0]); // prints the first line

Displaying License Badges

For documentation or README files, use standard badge syntax to indicate the dual-licensing nature:

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://github.com/different-ai/openwork/blob/dev/LICENSE)
[![License: Fair Source](https://img.shields.io/badge/License-Fair%20Source-blue.svg)](https://github.com/different-ai/openwork/blob/dev/ee/LICENSE)

Summary

• The Openwork project license employs a mixed-model strategy with MIT for core code and Fair Source for enterprise features.
• The LICENSE file at the repository root governs all files outside the /ee directory.
• Enterprise functionality in /ee requires compliance with the Fair Source License terms.
• Third-party dependencies maintain their original licenses as documented in NOTICE.

Frequently Asked Questions

Is the Openwork project completely open source?

While the majority of the codebase is open source under the permissive MIT License, the enterprise components in the /ee directory use the Fair Source License, which restricts commercial use without a subscription. Third-party dependencies retain their original licenses as specified in NOTICE.

Can I use Openwork commercially without restrictions?

The MIT-licensed core allows commercial use, modification, and distribution without fees. However, any usage of code from the /ee directory falls under Fair Source terms, which limit commercial deployment without obtaining a proper license or subscription from the maintainers.

Where can I find the full license text for the enterprise components?

The complete Fair Source License text is located in ee/LICENSE within the repository. This file specifically governs all code contained in the /ee directory and related enterprise functionality according to the repository's license hierarchy.

Do I need to include attribution when using Openwork in my project?

Yes, the MIT License requires retaining the copyright notice and permission notice found in the top-level LICENSE file. Additionally, you must comply with any attribution requirements specified in the NOTICE file for third-party components and respect the Fair Source restrictions if utilizing enterprise features from the /ee directory.
