This repository is a curated list of open-source Software-as-a-Service (SaaS) tools, categorized by function. It serves developers, product managers, and IT professionals looking for open-source alternatives to proprietary SaaS solutions across various domains like API Testing, Auth, CI/CD, CMS, Communication, CRM, Data Analytics, Databases, Deployment, Developer Tools, and many more. The primary benefit is providing a comprehensive, organized resource for discovering and evaluating open-source SaaS options.

How It Works

The repository functions as a directory, listing numerous open-source tools within distinct categories. Each entry typically includes the tool's name, a brief description, its GitHub stars (as a proxy for popularity/community engagement), and links to closed-source alternatives and social/documentation resources. This structure allows users to quickly scan and identify relevant tools for their needs.

Quick Start & Requirements

This is a curated list, not a runnable project. No installation or specific requirements are applicable.

Highlighted Details

• Extensive categorization covering over 30 distinct SaaS domains.
• Provides direct links to GitHub stars, documentation, and community resources for each tool.
• Includes comparisons to popular closed-source alternatives, aiding in evaluation.
• Offers a broad overview of the open-source SaaS landscape.

Maintenance & Community

The repository is maintained by Vihar, with contributions likely from the broader open-source community through GitHub pull requests. Specific community links (Discord/Slack) are provided per tool, not for the list itself.

Licensing & Compatibility

The repository itself is a list and does not have a specific license. The licensing of individual tools listed within the repository varies and must be checked on each tool's respective project page. Compatibility for commercial use depends entirely on the licenses of the individual tools.

Limitations & Caveats

The list's comprehensiveness is subjective and may not include every available open-source SaaS tool. GitHub stars are used as a popularity metric, which may not always correlate with a tool's suitability or maturity. The descriptions are brief, requiring further investigation into each tool's capabilities.
