    PowerHub

    PowerHub

    A post exploitation tool based on a web application

    ...It exposes a modular command set for inventorying systems, managing services, deploying packages, and executing remote commands with consistent logging and error handling. The project places emphasis on discoverability and reuse: scripts are organized into reusable modules and functions with clear parameter contracts so teams can compose higher-level workflows without duplicating glue code. Authentication and remoting are handled idiomatically via PowerShell remoting or credential stores, enabling both interactive and scheduled runs. Built-in reporting features aggregate results into human-readable summaries and machine-friendly outputs (CSV/JSON) for pipeline consumption or ticketing integration.

    WasmEdge

    WasmEdge

    Extensible WebAssembly runtime for cloud native applications

    ...Its use cases include modern web application architectures (Isomorphic & Jamstack applications), microservices on the edge cloud, serverless SaaS APIs, embedded functions, smart contracts, and smart devices. The WasmEdge Runtime provides a well-defined execution sandbox for its contained WebAssembly bytecode program. The runtime offers isolation and protection for operating system resources (e.g., file system, sockets, environment variables, processes) and memory space. The most important use case for WasmEdge is to safely execute user-defined or community-contributed code as plug-ins in a software product (e.g., SaaS, software-defined vehicles, edge nodes, or even blockchain nodes). ...

    A permissioned Ethereum smart-contract blockchain node

    ...Burrow is a fully-fledged blockchain node and smart contract execution engine -- a distributed database that executes code. Burrow runs Ethereum Virtual Machine (EVM) and Web Assembly (WASM) smart contracts. Burrow networks are synchronized using the Tendermint consensus algorithm. A node can detect if its state is corrupted or if a validator is dishonestly executing the protocol. Run a private or public permissioned network. Stakeholders may vote for autonomous smart contract upgrades. Application state is organised in an event stream and can drive external systems.

    joi-router

    joi-router

    Configurable, input and output validated routing for koa

    ...This object is not the exact same route definition object that was passed into koa-joi-router, nor is it used internally - any changes made to this object will not have an effect on your running application but is available to meet your introspection needs. Validating the output body and/or headers your service generates on a per-status-code basis is supported. This comes in handy when contracts between your API and client are strict e.g. any change in response schema could break your downstream clients. In a very active codebase, this feature buys you stability. If the output is invalid, an HTTP status 500 will be used.

    Twiggy

    Twiggy

    Twiggy is a code size profiler

    ...It works by inspecting a binary’s call graph and providing detailed breakdowns of which functions are included and how they are interconnected, allowing developers to trace dependencies and identify unnecessary code paths. This makes Twiggy particularly useful in performance-sensitive environments such as web applications, embedded systems, and blockchain smart contracts, where minimizing binary size is critical. The tool offers multiple analysis modes that answer questions like why a function is present, how much space it consumes, and what dependencies pull it into the final binary. By surfacing insights about symbol sizes and call relationships, Twiggy enables developers to optimize builds, remove dead code, and improve load times.
