Instant and scalable API to the Cardano blockchain.
Library for serialization & deserialization of data structures used in Cardano's Haskell implementation.
CardanoSharp Wallet is a .NET library for Creating/Managing Wallets and Building/Signing Transactions.
Plutus dApp which enables users to fractionalize their NFTs. The contract locks an NFT and mints a number of tokens representing fractions of it. To get the NFT back, the fraction tokens are burned.
A collection of tools (CNTools, gLiveView, topologyUpdater and more) to simplify typical operations to help community simplify wallet keys, pool management and interact with blockchain.
A Golang library for Cardano network, it is used and maintained by Bitrue.
In the browser-based Marlowe Playground you can write Marlowe contracts, in a variety of different ways.
Ogmios is a lightweight bridge interface (WebSocket + JSON/RPC) for cardano-node.
Oura is a rust-native implementation of a pipeline that connects to the tip of a Cardano node through a combination of Ouroboros mini-protocol, filters the events that match a particular pattern and then submits a succint, self-contained payload to pluggable observers called 'sinks'.
The Plutus Playground is a lightweight, web-based environment for exploratory Plutus development.

An Ansible playbook that helps operators provision and maintain a secure Cardano stake pool.
A Python library that benefits the token & NFT communities. Scripts allow easy wallet management, automatic creation of unlocked and time-locked policy IDs, as well as the ability to quickly: build, sign, and submit transactions, and much more. Note: This library relies on wrapping cardano-cli.
A client library for Cardano in Java. For some features like transaction signing and address generation, it currently uses cardano-serialization-lib rust library though JNI.
A set of lightweight tools to operate and maintain a Cardano Stake Pool. Currently includes a leaderlog script based on BlockFrost (no need for working cardano-cli/cardano-node setup and less CPU/mem utilization) and a monitoring script to log relevant metrics directly into a text file in human-readable form (less complex and more resource-efficient than Grafana).
Oracle submitting information using Cardano Metadata
This is a Typescript/Javascript version of the cardano-addresses API. It includes a web demo.
A Javascript/Typescript library to easily interact with the dApp connector of various wallets.
A javascript/typescript SDK for Cardano Wallet with a extra functionalities. You can use it as a client for the official cardano-wallet and also to create Native Tokens and NFTs.
A library that wraps the cardano-cli in JavaScript.
Kubernetes-based project to easily deploy Cardano APIs and a free, hosted community service to access all of them instantly.
An automation platform for Cardano to trigger various action based on detecting payment to a wallet address.
A collection of Plutus-related helper libraries.
Helps developers to estimate the cost of smart contract scripts for maximum efficiency and minimum cost.
The Pooldata public API provide several operational metrics for SPOs in the form of time-series and tabular data. It can be plugged directly to a Grafana environment as datasource.
A Cardano library written in Python. It allows users to build and sign transactions without depending on other Cardano serialization tools (such as cardano-cli and cardano-serialization-lib), making it a lightweight library that is easy and fast to set up in all kinds of environments.
The module provides tools for developers to accept and send transactions, manage staking and much more. It uses cardano-wallet as backend but is future-compatible with other solutions.
