Contributing

Your contributions are always welcome! Please ensure your pull request meets the following guidelines.

Entry Format

Each non-commercial entry must include one or more backtick-delimited tags and follow one of these formats. Tags work like a compact tag cloud: use concise terms that help readers understand the project, such as programming languages, runtimes, protocols, interfaces, data types, or domains.

Single tag

- [Project Name](https://github.com/owner/repo) - `Python` - Short description ending with a period.

Tags are not limited to programming languages. For example:

- [Project Name](https://github.com/owner/repo) - `MCP` - Short description ending with a period.

Multiple tags

List each tag separately in adjacent backticks:

- [Project Name](https://github.com/owner/repo) - `Python` `Rust` `MCP` - Short description ending with a period.

Project with website and GitHub repo

For projects that have a dedicated website, link to the site and append the GitHub repo in the description:

- [Project Name](https://project-site.com) - `Python` - Short description ending with a period. [GitHub](https://github.com/owner/repo)

CRAN project

Link to the CRAN package page. If the project has a GitHub repo, append it after the description:

- [Package Name](https://cran.r-project.org/package=pkgname) - `R` - Short description ending with a period.
- [Package Name](https://cran.r-project.org/package=pkgname) - `R` - Short description ending with a period. [GitHub](https://github.com/owner/repo)

PyPI project

Link to the PyPI package page. If the project has a GitHub repo, append it after the description:

- [package-name](https://pypi.org/project/package-name/) - `Python` - Short description ending with a period.
- [package-name](https://pypi.org/project/package-name/) - `Python` - Short description ending with a period. [GitHub](https://github.com/owner/repo)

General rules

  • Use https:// URLs only.
  • GitHub repository URLs are strongly preferred and are a major positive relevance signal. Projects with a verifiable GitHub repository are easier to evaluate for source availability, documentation, activity, maintenance, and community adoption, and they receive automated tracking of stars, activity, and archive status on awesome-quant.com.
  • Include a GitHub repository either as the main project URL or as the exact [GitHub](https://github.com/owner/repo) suffix. A valid GitHub repository mentioned in either place receives the same relevance consideration.
  • Use short, meaningful tags. Each concept must have its own backtick pair; for example, use `Python` `C++` rather than `Python, C++`.
  • The description must end with a period (before the [GitHub] link, if present).
  • Keep descriptions concise — one sentence.

Quality Requirements

  • Active: Project must show recent activity (commits within the last 12 months).
  • Documented: Clear README with usage examples.

Commercial & Proprietary Projects

Commercial and proprietary projects are welcome. They will be placed under the Commercial & Proprietary Services section. Include a link to the product website and a brief description of what it offers.

Placement rule: If the main URL (the first link) is a commercial website and there is no GitHub repository link (as a second URL), the entry must be placed in the Commercial & Proprietary Services section. This applies to:

  • SaaS platforms and APIs
  • Commercial data providers
  • Paid subscription services
  • Any proprietary product without open-source code

Projects with GitHub repositories may be placed in other sections based on their functionality. A public repository is a strong relevance signal even when the project also has a commercial website, but it does not by itself prove that the entire product is open source.

Section Placement

The README is organized by category (not by language). Add your entry under the appropriate category heading (##). The available categories are:

  • Numerical Libraries & Data Structures
  • Financial Instruments & Pricing
  • Technical Indicators
  • Trading & Backtesting
  • Portfolio Optimization & Risk Analysis
  • Factor Analysis
  • Sentiment Analysis & Alternative Data
  • Time Series Analysis
  • Market Data & Data Sources
  • Prediction Markets
  • Calendars & Market Hours
  • Visualization
  • Excel & Spreadsheet Integration
  • Quant Research Environments
  • Cross-Language Frameworks
  • Reproducing Works, Training & Books
  • Commercial & Proprietary Services
  • Related Lists

For example, if your project is a Python backtesting library, it goes under ## Trading & Backtesting (not under Technical Indicators or another category).

If no existing category fits, suggest a new one in your PR description.

Multiple Related Projects Per PR

Preferred: One project per pull request for clarity and focused reviews.

Acceptable: Multiple closely related projects in a single PR if they share a common theme or data source. Examples:

  • Multiple data sources from the same market or exchange (e.g., all NSE/BSE tools for Indian markets)
  • Multiple tools from the same author with complementary functionality
  • Multiple APIs/SDKs for the same service or data provider
  • Related packages addressing a specific domain gap (e.g., UK company identifier validators)

When submitting multiple projects:

  • Explain the relationship and rationale in the PR description
  • Ensure each entry is placed in the correct section
  • Avoid creating duplicate entries within the same README file
  • All entries must meet quality and format requirements independently

Before Submitting

  1. Search the existing list to make sure the project is not already included.
  2. Search previous Pull Requests (open and closed) to avoid duplicates.
  3. Make sure the entry format matches exactly — our parser relies on it.

Automatic Rejection

PRs will be closed if:

  • Multiple unrelated projects added in a single PR without a clear grouping rationale.
  • Entry format does not match the required pattern.
  • Duplicate of an existing entry or a recently closed PR.
  • Project is archived or abandoned.
  • Empty PR description.
