Overview
Public APIs is a searchable directory that helps developers discover APIs for their projects. Users can search and filter entries by name, description, category, authentication requirement, HTTPS support, and CORS availability.
Why I Built This
I kept finding interesting APIs in public API lists but struggled to discover them efficiently. A searchable interface made it easier to compare the fields that matter when choosing an API.
Key Features
Search and Filter
Search API names and descriptions, then filter by category, authentication type, HTTPS support, or CORS availability.
Pagination
Browse the directory through paginated results and open the source documentation for each entry.
Responsive Grid Layout
API entries are displayed in a card grid that adapts to different screen sizes.
Dark Mode
The app supports light and dark themes and follows the system preference by default.
Product Hunt Recognition
The current site includes Product Hunt badges for the project’s original launch.
Build Notes
Cached Data Sources
The app fetches category and paginated list data from a configured publicapis.dev API with revalidation. The full resource view also reads GitHub-hosted JSON from the marcelscruz/public-apis repository through a cached server-side request.
Next.js Cache Components
The current codebase uses Next.js 16 Cache Components and partial prefetching. SWR handles interactive client-side requests where the UI needs to refetch data.
Tech Evolution
The project started with Chakra UI and later moved to Tailwind CSS and Radix UI primitives. The current implementation keeps the directory focused on search, filtering, and browsing.
Current Status
The codebase is actively maintained. Recent work upgraded Next.js and TypeScript and moved the data-fetching paths to the current Next.js caching model.
