Redlib

Redlib is a self‑hosted, privacy‑centric front‑end for Reddit built entirely in Rust. It proxies all client requests—HTML, JSON, and media—through its own HTTP server, ensuring that no third‑party tracking or analytics can be injected. The application is deliberately lightweight: it serves static HTML without JavaScript, eliminates ads, and relies on a strong Content Security Policy to block any direct browser access to Reddit’s endpoints. From a developer perspective, Redlib presents an opportunity to host a performant, low‑footprint Reddit alternative that can be integrated into existing infra with minimal overhead.

Technical Stack

• Language & Runtime: Rust 1.70+ with the hyper HTTP library for asynchronous request handling.
• Web Server: A custom hyper‑based server that implements routing, caching, and response transformation.
• Data Layer: No persistent database; all data is fetched live from Reddit’s public API and served as‑is. Optional in‑memory caching can be added via lru_cache or external services (Redis, Memcached).
• Packaging: Binary releases are distributed as statically linked executables on Quay.io and GitLab, enabling easy deployment in containers or as systemd services.

Core Capabilities

• API Proxying: Every request to a Reddit endpoint is forwarded through the server, with response headers stripped or replaced to enforce privacy.
• Media Handling: Images, videos, and GIFs are fetched server‑side and served with safe MIME types, preventing cross‑origin leaks.
• Content Rendering: Server‑side rendering of Reddit posts and comments into clean, minimal HTML. Markdown is parsed locally; no client‑side rendering logic.
• Rate Limiting & Backpressure: Built‑in request throttling to respect Reddit’s API limits, configurable via environment variables.
• Extensibility Hooks: A simple plugin interface (feature flags in Cargo.toml) allows developers to add custom endpoints or modify request/response pipelines without touching core code.

Deployment & Infrastructure

Redlib is designed for seamless self‑hosting:

• Containerization: Official Docker images are available on Quay.io; a docker-compose.yml template supports multi‑container setups (e.g., with Redis for caching).
• Systemd Service: A drop‑in unit file is provided; the binary can run as a background service with log rotation via systemd-journald.
• Podman & Quadlets: Native support for Podman, with example quadlet files to spin up a single‑file deployment.
• Binary Only: For minimal environments, the static binary can be copied to /usr/local/bin and launched directly.

Scalability is achieved through horizontal scaling of stateless containers behind a reverse proxy (Traefik, Nginx). Because Redlib does not maintain state beyond transient caches, any number of replicas can share the same Redis instance for caching.

Integration & Extensibility

• Webhooks: The server exposes a /webhook endpoint that can be triggered by external services to refresh cached content or perform maintenance tasks.
• Plugin System: Developers can fork the repository and enable/disable modules in Cargo.toml. For example, adding a “search” module or custom subreddit filters requires only re‑compiling the binary.
• Custom Themes: The static CSS is modular; contributors can swap out themes by editing the assets/ directory and rebuilding.
• API Documentation: Inline Rust docs expose request handling logic; the public API is fully typed, making it straightforward to generate OpenAPI specs if needed.

Developer Experience

The project follows Rust’s idiomatic patterns: a clear src/ hierarchy, extensive unit tests, and cargo scripts for building. Documentation is housed in the docs/ folder and the README, with a dedicated “Contribution” guide that covers linting, testing, and pull‑request workflows. Community support is active on Matrix, GitHub Discussions, and a public issue tracker where feature requests (e.g., “support for Reddit’s new API v2”) are prioritized.

Use Cases

• Enterprise Intranet: Organizations can host a private Reddit mirror for internal knowledge sharing, ensuring no external tracking.
• Educational Platforms: Schools can provide students with a clean Reddit interface for research, free of ads and social media noise.
• Personal Privacy: Developers who run home servers (e.g., Raspberry Pi, NAS) can deploy Redlib to browse Reddit without exposing credentials to third parties.
• Kiosk & Public Displays: The lightweight nature of Redlib makes it ideal for public terminals that need to display Reddit content without JavaScript overhead.

Advantages Over Alternatives

• Performance: Rust’s async runtime delivers low latency and high throughput, outperforming Node.js or Go‑based front‑ends.
• Memory Safety: No garbage collector; the binary is deterministic and less prone to runtime crashes.
• Licensing: Open source under Apache‑2.0, allowing commercial use without attribution concerns.
• Zero JavaScript: By eliminating client‑side code, Redlib reduces attack surface and improves accessibility for users with script blockers.
• Full Control: Self‑hosting guarantees that all data stays on your infrastructure, a key requirement for privacy‑conscious teams.

In summary, Redlib offers developers a robust, high‑performance platform to host a privacy‑first Reddit experience. Its Rust foundation, minimalistic design,
