Frequently asked questions
What is this open-source directory?
It is a curated, regularly updated directory of the most popular and useful open-source projects on GitHub, organized by industry and domain — from AI and machine learning to robotics, health tech, security, web development, and more. Every entry links to the real GitHub repository, with live star counts, primary language, and topics pulled directly from the GitHub API.
How are the repositories chosen and ranked?
Repositories are selected by popularity (GitHub stars) within each category using the public GitHub Search API, then deduplicated and assigned to the most relevant industry category. Only well-known, actively useful projects above meaningful star thresholds are included — archived projects and forks are excluded. Within each category, repositories are ranked by star count.
What categories of open-source software are covered?
Categories include AI & Machine Learning, LLMs & Generative AI, Robotics & Autonomous Systems, Health Tech & Bioinformatics, Security & Cryptography, Data Science & Analytics, DevOps & Cloud Infrastructure, Databases, Web Frontend, Backend & Frameworks, Mobile Development, Developer Tools, Programming Languages & Compilers, Blockchain & Fintech, Game Development, and curated learning resources.
Are the star counts accurate?
Yes — star counts, descriptions, languages, and topics are fetched directly from GitHub and reflect a snapshot taken on the last-updated date shown on the page. GitHub stars change continuously, so figures may drift slightly between refreshes.
How can I suggest a repository?
Email hello@opencurious.com with the GitHub URL and the category you think it belongs to. We prioritize widely used, well-maintained open-source projects that are genuinely useful to developers, researchers, and operators.
