Open Source Licenses & Architecture

Discover the open-source libraries and technologies that power the free, secure, and client-side tools at Futurestant.

At Futurestant, our primary mission is to deliver a highly secure, lightning-fast, and completely free collection of digital utilities directly to your web browser. We understand that in today’s digital age, privacy and data security are more important than ever. That is exactly why our entire platform is built on a strict client-side architecture. This means that when you use our image compressors, PDF converters, or developer utilities, your files never leave your device. All the heavy computational lifting and complex data processing happens right inside your own computer or mobile phone.

However, building such a powerful and private ecosystem from scratch would take lifetimes. Therefore, Futurestant proudly stands on the shoulders of giants. We heavily rely on the brilliant and generous global open-source community. The open-source community consists of thousands of passionate software engineers, researchers, and organizations who build free, foundational code for the public to use.

In strict compliance with global software distribution regulations, and to maintain the highest standards of transparency for our users and advertising partners, this page serves as our official legal acknowledgment. Below, you will find a comprehensive list of the third-party libraries, frameworks, and toolkits that make Futurestant possible.

1. Apache License 2.0 Libraries

The Apache License 2.0 is a permissive free software license written by the Apache Software Foundation. It allows users to safely use the software for any purpose, distribute it, and modify it, while providing an express grant of patent rights from contributors to users.

MediaPipe Vision Engine

Apache 2.0

Developed by Google, this advanced machine learning framework powers our client-side semantic image segmentation. It allows our tools to accurately detect subjects and objects in your photos locally, without ever sending your private pictures to a remote cloud server.

Math.js Toolkit

Apache 2.0

This is an extensive mathematical library for JavaScript. It features a flexible expression parser and offers an integrated solution to work safely with complex numbers, fractions, and matrices. We use this to power our complex algebraic and scientific calculators.

PDF.js Engine

Apache 2.0

Created by Mozilla, this robust library renders Portable Document Format (PDF) files using standards-compliant web technologies. It ensures you can preview, read, and manipulate your documents smoothly and securely within your browser environment.

Tesseract.js

Apache 2.0

This is a pure JavaScript port of the popular Tesseract Optical Character Recognition (OCR) engine. It enables Futurestant to read and extract text from your scanned images instantly, without relying on external APIs.

2. MIT License Libraries

The MIT License is one of the most popular and permissive software licenses in the world. It puts very few restrictions on reuse, meaning developers can freely use, change, and distribute the code as long as they include the original copyright and license notice.

Browser Image Compression

MIT License

This highly efficient module provides native client-side image matrix adjustments and resolution scaling. It is the core engine behind our tool that shrinks your heavy image files into smaller sizes for faster web sharing and storage.

PDF-Lib & jsPDF

MIT License

These powerful libraries handle document modification, layout rendering, split vectors, and multi-page combinations. They are the mathematical magic behind our tools that let you seamlessly merge, split, and edit PDF files.

Exifr Data Parser

MIT License

An advanced, ultra-fast client-side image metadata parser. We utilize this for our forensic extraction tools, allowing you to easily read the hidden EXIF data (such as camera model, exposure, and GPS location) saved deep inside your digital photographs.

JSZip Engine

MIT License

This library enables high-speed memory buffering and synchronous file zipping locally. When you download multiple processed files from Futurestant at once, JSZip packages them neatly into a single compressed ZIP archive for your convenience.

Marked.js & Turndown

MIT License

These interconnected libraries provide robust bidirectional conversion between Markdown syntax and standard HTML text. They are absolutely essential for our developer tools and advanced text formatting utilities.

CryptoJS

MIT License

This growing collection of standard and secure cryptographic algorithms allows us to offer secure hashing generators, password generation, and data encoding tools directly in your browser without server-side processing.

QRCode.js

MIT License

A lightweight, exceptionally fast library used for generating Quick Response (QR) codes instantly based on your custom text, vCards, or URL inputs.

SQL Formatter

MIT License

This helpful parser takes messy, unformatted, and deeply nested database query strings and beautifully formats them into clean, highly readable SQL logic for software developers.

3. GNU AGPL v3 License

The GNU Affero General Public License is a free, copyleft license designed specifically to ensure cooperation with the community in the case of network server software.

@imgly/background-removal

GNU AGPL v3

This powerful library provides local WebAssembly (WASM) powered neural network processing. It allows Futurestant to offer highly accurate background deletion from images without requiring an active server connection.

4. BSD License

The BSD licenses are a family of permissive free software licenses that generally have fewer restrictions on distribution compared to other copyleft licenses.

JSDiff

BSD License

This library contains the algorithms responsible for comparing text side-by-side. It powers our Text Diff Checker, finding identical words, missing characters, and structural differences to help developers and writers spot changes quickly.
