Open-source alternatives to PptxGenJS

Presentation-ai is a system for the automated creation of slide decks and visual layouts from text descriptions or specific topics using large language models. It generates structured content and maps it to visual templates to produce complete presentations. The project distinguishes itself by supporting local language model integration, allowing for private content generation without reliance on external cloud providers. It also includes an AI image generator to produce context-aware visual assets and imagery tailored to the presentation content. The platform provides a web-based editor for

pdfmake is a JavaScript PDF generation library and declarative document engine that transforms structured JavaScript objects into formatted PDF files. It functions as a layout engine capable of producing documents on both the client side within a web browser and on the server side using Node.js. The library utilizes a declarative approach to translate object-based document definitions into final PDFs. It distinguishes itself through a virtual layout engine that calculates element positions and page breaks and an inheritance-based style system that uses dictionaries to maintain visual consiste

Recorderjs is a Web Audio API recording library and buffer capture tool used for capturing real-time audio output from processing nodes. It functions as a client-side audio capture utility that records sound directly within a web browser. The project provides a WAV file exporter that converts captured audio buffers into downloadable binary large objects. This allows audio data to be saved as standard Waveform Audio File Format files for local storage or playback. The library manages audio streams using floating-point arrays to maintain data fidelity and supports the export of raw stereo buff

This project is a GitHub profile README generator and markdown profile builder. It functions as a developer portfolio generator that converts personal information and preferences into a structured Markdown file for use as a public profile landing page. The tool focuses on developer portfolio branding and GitHub profile customization. It uses a series of templates to automate the layout of a professional presence, allowing users to showcase their skills and social links. The generator utilizes form-driven data collection and conditional content logic to determine which sections appear in the

mcp-context-forge is a Model Context Protocol federation gateway that unifies diverse AI tool servers and APIs into a single consistent interface for discovery and execution. It acts as a centralized proxy that aggregates multiple servers and APIs, allowing AI agents to access and invoke a unified set of tools, prompts, and resources. The project distinguishes itself through a multi-protocol translation bridge that converts communication between standard I/O, SSE, gRPC, and REST to enable interoperability between disparate tool servers. It includes a comprehensive LLM evaluation framework for

This project is a suite of tools for generating encoded shell commands and network listener configurations used in offensive security operations. It provides a collection of command generators for various shells and listeners to establish remote access during security penetration tests. The tool features a reverse shell payload generator that creates encoded command strings and a network listener command generator that produces the server-side syntax needed to accept incoming network connections. It includes a Base64 command encoder to transform shell commands into encoded strings to bypass s

unfetch is an isomorphic HTTP client and network library that provides a promise-based interface for performing network requests consistently across both browser and server environments. It serves as a lightweight implementation of the Fetch API for environments that lack native support for making network requests. The library enables the retrieval of web resources as text, JSON, or binary blobs while maintaining a small memory footprint. It functions as a polyfill by installing the fetch interface into the global namespace when native browser support is unavailable. The tool covers broad ca

Buffer is a library for binary data manipulation that provides a browser-compatible implementation of the Node.js binary data application programming interface. It enables developers to create, modify, and process raw binary data structures within web environments using a consistent interface that mirrors server-side standards. The library distinguishes itself by providing a unified approach to cross-platform JavaScript development, allowing for shared code between server and browser environments. It achieves this by polyfilling standard binary methods and extending the native byte array prot

DataTables is a feature-rich HTML table library that transforms static HTML tables into interactive data grids with sorting, paging, filtering, and server-side processing support. It provides a client-side rendering engine that handles table rows, pagination, and sorting entirely in the browser, while also offering a server-side processing pipeline that offloads sorting, filtering, and paging operations to a backend for efficient handling of large datasets. The library distinguishes itself through its plugin-based extension system, which allows custom functions and widgets to modify table beh
