// 1h agoOPENSOURCE RELEASE

Vaultwarden is a lightweight, self-hosted Bitwarden-compatible server implementation written in Rust designed for minimal resource consumption.

Vaultwarden (formerly bitwarden_rs) is an unofficial, open-source server implementation compatible with standard Bitwarden client applications, browser extensions, and mobile apps. Written in Rust, it provides a high-performance, drop-in backend alternative to the official Bitwarden server stack, replacing heavy enterprise microservices and Microsoft SQL Server requirements with embedded SQLite, PostgreSQL, or MySQL. It enables individuals, families, and small organizations to securely self-host vault data, secrets, and credentials on minimal hardware such as Raspberry Pis or budget VPS instances without sacrificing upstream client features.

// ANALYSIS

Vaultwarden remains the benchmark for community-driven backend re-engineering, delivering massive resource savings for self-hosters while navigating the maintenance challenges of tracking an evolving proprietary-adjacent ecosystem.

–Minimal footprint: Operates smoothly on tens of megabytes of RAM, drastically cutting infrastructure overhead relative to the official multi-container .NET stack.
–Broad client interoperability: Maintains tight API compatibility across Bitwarden desktop, mobile, CLI, and browser extensions, including support for organization vaults and Bitwarden Send.
–Simplified operations: Offers single-binary or straightforward container deployments with flexible database options (SQLite, PostgreSQL, MySQL) that streamline local backup and recovery.
–Ecosystem trade-offs: Lacks enterprise compliance certifications and direct upstream vendor support, making it ideal for homelabs and small teams rather than large regulated enterprise environments.

SnailSploit releases Claude-Red, a curated offensive security skill library equipping Claude with expert red teaming and exploit development capabilities.

Claude-Red is an open-source library of offensive security skills designed specifically for the Claude skills ecosystem. Packaged as structured SKILL.md modules, the repository primes Claude with specialized, practitioner-level methodologies across diverse attack vectors—ranging from web application exploits like SQL injection to low-level techniques including shellcode generation, EDR evasion, and binary exploit development. By embedding tactical tradecraft into modular agent skills, Claude-Red enables security professionals to streamline penetration testing, vulnerability research, and adversary simulation workflows directly within Claude.

LocalSend crosses 91,000 GitHub stars as the leading open-source, cross-platform alternative to Apple AirDrop.

LocalSend is a cross-platform, open-source file and message sharing application built with Flutter that enables instant peer-to-peer transfers across local Wi-Fi networks without relying on cloud servers or third-party infrastructure. Available across Windows, macOS, Linux, Android, and iOS, the tool uses a lightweight REST API over HTTPS to discover nearby devices and transfer files, directories, text snippets, and clipboard content directly between heterogeneous operating systems with zero account creation or setup friction.
