Open Source Credits & Upstream References

greenpng is built upon the collective intelligence of the global open-source community. We express our deepest gratitude to the creators, maintainers, and security researchers behind these foundational technologies.

🌐 Edge Gateway & Networking Core

Cloudflare Pingora Apache 2.0

A programmable network proxy framework written in Rust. Powers greenpng's gr-probe-plane for TLS termination, connection pooling, and sealed ingest.

cloudflare/pingora ↗
Tokio MIT

The de-facto asynchronous runtime for the Rust programming language, providing event-driven non-blocking I/O and thread scheduling.

tokio-rs/tokio ↗
Axum MIT

Ergonomic and modular web application framework designed to take full advantage of Tower, Hyper, and the Tokio ecosystem.

tokio-rs/axum ↗
OpenSSL Apache 2.0

The TLS backend for greenpng's Pingora edge gateway and admin control plane (pingora openssl feature): modern TLS 1.3, battle-tested and everywhere.

🔐 Cryptography & Compression

flate2 / zlib MIT

Real-time lossless compression (deflate/zlib) for probe batch payloads in gr-probe-store. zstd ships only inside the vendored pingora tree.

rust-compress/flate2 ↗
ed25519-dalek BSD-3-Clause

Fast, secure Ed25519 digital signature library in pure Rust, used for verifying browser probe asset trees and OTA distribution bundles.

💾 Data Persistence & Clustering

PostgreSQL PostgreSQL License

The world's most advanced open source relational database. Serves as greenpng's L3 cold storage, tenant catalog, and forensic repository.

postgresql.org ↗
Redis RSALv2 / SSPL

In-memory data structure store used for real-time distributed rate limiting, cluster node heartbeat gossip, and cache invalidation.

redis.io ↗
SQLite Public Domain

Self-contained, serverless SQL database engine utilized for lightweight single-node and edge embedded deployments.

đŸ”Ŧ Browser Research & Fingerprinting Pioneers

greenpng's hardware feature extraction and anti-spoofing vectors were heavily inspired by seminal papers and open-source benchmarks in modern browser security:

CreepJS Open Research

Groundbreaking research in browser anti-fingerprinting and prototype tampering detection. greenpng's B1 conflict and B12 anti-camouflage detectors build upon concepts first surfaced by CreepJS.

abrahamjuliot/creepjs ↗
FingerprintJS BSL 1.1 / Apache 2.0

Pioneers of client-side browser fingerprinting components (Canvas, AudioContext, WebGL, Font enumeration, WebRTC).

fingerprintjs/fingerprintjs ↗
BotD Apache 2.0

Open-source client-side bot detection library providing fundamental patterns for spotting automation frameworks (Puppeteer, Playwright, Selenium, PhantomJS).

fingerprintjs/botd ↗
Element Plus & Vue 3 MIT

The responsive desktop UI component library that provides the administrative console interface for greenpng's control plane.
