Hyperledger FireFly
Hyperledger FireFly is the first open source Supernode: a complete stack for enterprises to build and scale secure Web3 applications.
The FireFly API for digital assets, data flows, and blockchain transactions makes it radically faster to build production-ready apps on popular chains and protocols.

Start using Hyperledger FireFly
The best place to learn about FireFly is in the documentation.
There you will find our Getting Started Guide, which will get you a running FireFly network of Supernodes on your local machine in a few minutes.
Your development environment will come with:
| FireFly CLI | FireFly Explorer UI | FireFly Sandbox |

Technical architecture
Hyperledger FireFly has a pluggable microservices architecture. Everything is pluggable, from the Blockchain technology, token ERC standards, and custom smart contracts, all the way to the event distribution layer and private database.
So if there aren't yet instructions for making FireFly a Supernode for your favorite blockchain technology - don't worry. There is almost certainly a straightforward path to plugging it in that will save you from re-building all the plumbing for your blockchain application from scratch.
Start contributing to Hyperledger FireFly
There are lots of places you can contribute, regardless of whether your skills are front-end, backend-end, or full-stack.
Check out our Contributor Guide, and welcome!.

Awesome-Selfhosted is a community-maintained GitHub list at awesome-selfhosted/awesome-selfhosted that catalogs Free Software network-service and web-app projects meant for running on a server you control rather than someone else's cloud. Entries are grouped by category, each tagged with a license and a language or deployment option, and the project keeps proprietary alternatives on a separate Non-Free page.
Node.js Best Practices, maintained at goldbergyoni/nodebestpractices, is a curated checklist of more than 80 recommendations for building Node.js applications, organized into eight categories from project architecture to Docker. Each entry combines a short recommendation with an explanation of the risk of skipping it and a link to a deeper write-up, rather than being a plain list of links.
NestJS is an open-source Node.js framework at nestjs/nest, written primarily in TypeScript while preserving compatibility with plain JavaScript. Its README frames it as an architecture-first alternative to hand-assembling Express or Fastify, blending object-oriented, functional, and functional-reactive patterns into an Angular-inspired structure. The GitHub description bills it as aimed at server-side software that's efficient, scales, and holds up at enterprise scale, and the repo carries strong community support in the facts provided here.
Caddy is an HTTP/1-2-3 web server, written in Go, which provides automatic HTTPS by default, utilizing services like ZeroSSL and Let's Encrypt for public names or a local CA for internal ones. It supports flexible configuration through its native JSON API, a Caddyfile, or various other formats via config adapters. The project highlights a modular architecture for extensibility, runs on multiple platforms without external dependencies, and benefits from Go's memory safety features. The README indicates it has served trillions of requests and managed millions of TLS certificates, scaling to hundreds of thousands of sites in production. Caddy began development in 2014 and was an early adopter of automatic HTTPS by default.
