lightningdevkit/rust-lightning

A highly modular Bitcoin Lightning library written in Rust. It's rust-lightning, not Rusty's Lightning!

View on GitHub

What it does

This project is a software toolkit that helps developers add Bitcoin Lightning Network payments to their apps — Lightning being a system that lets people send Bitcoin instantly and cheaply without waiting for slow blockchain confirmations. It's designed to be highly flexible, meaning developers can plug it into almost any product without being locked into a specific technical setup.

Why it matters

As Bitcoin payment adoption grows, Lightning is becoming the go-to standard for fast, low-fee transactions, and this library is one of the most widely used building blocks for products integrating those payments. For founders and investors, backing or building on this toolkit means accessing a battle-tested, production-ready foundation rather than starting from scratch in a space where payment reliability is critical.

The Supabase CLI is a command-line tool that lets developers manage their Supabase projects — an open-source alternative to Google's Firebase backend platform — directly from their computer's terminal. It handles everything from setting up a local development environment and managing database changes, to deploying serverless functions and automatically generating code types from your database structure.

// why it matters As more startups look to avoid vendor lock-in with proprietary backends like Firebase, Supabase has emerged as a serious open-source contender, and this CLI is the primary tool that makes that workflow practical at scale. With nearly 1,800 stars and 162 contributors, it signals strong developer adoption — meaning teams building on Supabase have a mature, community-backed toolchain that can support everything from side projects to production applications.

Homebrew Core is the central library of software packages for Homebrew, the most popular free tool for installing software on Mac and Linux computers. It contains thousands of pre-built recipes that let developers quickly install common software tools with a single command instead of manually downloading and configuring them.

// why it matters With over 15,000 stars and 15,000 contributors, Homebrew is effectively the default way millions of developers set up their machines, making it a critical distribution channel for developer-facing software. If you're building a tool that developers need to install, getting it listed here dramatically lowers the barrier to adoption and signals legitimacy to a technical audience.

Cognetivy gives AI coding assistants a structured memory and process system, storing their work — including what steps were taken, what decisions were made, and what was produced — in an organized folder on your computer. Instead of losing important context when an AI coding session ends, everything is saved as traceable, repeatable workflows that you can review, rerun, and compare.

// why it matters As AI coding agents become central to software development, the ability to audit, repeat, and improve what those agents do is quickly becoming a competitive advantage — especially for teams that need accountability or consistency. Cognetivy is positioning itself as foundational infrastructure for this shift, similar to how version control became non-negotiable once teams grew beyond solo developers.

LLVM is the foundational technology that turns code written by developers into programs that computers can actually run, and it's used to build compilers for languages like C, C++, and many others. Think of it as the invisible translation engine that sits behind many of the world's most popular programming languages and development tools.

// why it matters Nearly every major tech company — Apple, Google, Meta, and more — relies on LLVM to power their software development pipelines, meaning it underpins the tools that build most modern apps and systems. For builders, understanding LLVM matters because it's the infrastructure behind emerging programming languages and performance-critical software, making it a key leverage point for teams building developer tools, new languages, or platform technologies.
