MarkItDown

MarkItDown is a lightweight Python utility designed to convert a variety of file formats into Markdown while preserving key structural elements such as headings, lists, tables, and links. It optimizes the output for consumption by large language models and text analysis pipelines, ensuring that document structure and content remain intact even as visual fidelity takes a backseat to machine readability. By streamlining the conversion process and focusing on consistent, structurally rich Markdown, MarkItDown simplifies the integration of diverse documents into automated workflows and enhances the efficiency of downstream analysis.

Claude Code Router

Claude Code Router is a local proxy service running on localhost:3456 that intercepts API calls from the Claude Code CLI tool and intelligently routes them to different large language model providers. Acting as transparent middleware, it enables Claude Code to work seamlessly with various AI models beyond Anthropic’s Claude, empowering users to optimize costs and select specialized models tailored to specific tasks. By abstracting endpoint management and routing logic, Claude Code Router simplifies model experimentation and integration, streamlining AI-driven workflows across diverse provider ecosystems.

uBlock Origin

uBlock Origin (uBO) is a comprehensive, CPU‐ and memory‐efficient content blocker extension for modern web browsers, designed to block unwanted content such as ads, trackers, malware sites, and other privacy‐invading elements. It uses filter lists to identify and block threats, while offering users granular customization options—allowing them to create custom filters, whitelist trusted sites, and adjust performance settings. With its low resource footprint and powerful filtering engine, uBlock Origin enhances browsing speed, strengthens privacy protections, and reduces security risks.

Graphiti

Graphiti is a Python library that enables AI agents to build and query temporally-aware knowledge graphs from dynamic data sources, offering real-time incremental updates and explicit temporal tracking to maintain both event occurrence and recording history. Unlike traditional retrieval-augmented generation (RAG) workflows that depend on batch processing and static summaries, Graphiti continuously ingests user interactions, structured data, and external information without full recomputation. It supports precise point-in-time queries through dedicated temporal reasoning, combines semantic embeddings, keyword search (BM25), and graph traversal for hybrid retrieval, and allows developers to define custom domain entities and relationships via Pydantic models.

Open Deep Research

Open Deep Research is a fully open-source AI-powered research automation platform built on LangGraph that orchestrates multiple specialized AI models, search APIs, and external tools in an iterative, configurable workflow to conduct comprehensive deep research and generate detailed reports on any topic. Its modular architecture supports seamless integration with diverse model providers, search engines, and Model Context Protocol (MCP) servers, enabling end-to-end automation from data gathering through analysis and synthesis.

Gitleaks

GitLeaks is a security scanning tool that helps developers and security professionals identify leaked secrets within their codebases by sensitive data through customizable, pattern-based rules. It supports multiple scanning modes, reporting formats, and integration options.

Strapi

Strapi is a flexible headless CMS that decouples content management from presentation, empowering developers to build with any frontend technology while offering content creators an intuitive administrative interface. It supports multiple database engines and scales seamlessly from simple websites to large enterprise applications, automatically generating both RESTful and GraphQL APIs and providing visual content type modeling. Strapi also includes built-in user authentication with role-based permissions, robust media asset management across various storage providers, multi-language content support, and enterprise workflow management. With its extensive plugin ecosystem and deep customization options, Strapi delivers a powerful, end-to-end backend solution for modern web development.

Folo

Folo is a cross-platform RSS reader with AI-powered features, built as a monorepo supporting desktop, mobile, and server-side rendered web applications.
