Comeonin is the long-standing password-security library for Elixir that standardizes secure hashing and verification practices in Phoenix and Plug applications. It provides a uniform interface for modern algorithms such as Argon2, Bcrypt, and PBKDF2 (implemented in companion packages), along with guidance for salts, cost factors, and timing-safe comparisons. The library’s helpers make it straightforward to add registration and login flows that resist brute-force and side-channel attacks....

Fast Elixir is a curated collection of performance-focused best practices, idioms, and code snippets for writing efficient Elixir programs. The project documents common patterns in Elixir and compares their relative performance using benchmarks to guide developers toward faster and more memory-friendly code. By showcasing side-by-side examples, it highlights not only which approaches are faster but also why certain functions or techniques should be preferred in different scenarios. The...

Swarm is a distributed process registry for Elixir/Erlang that lets you register and discover processes across a cluster as if they were on a single node. It focuses on automatic distribution and rebalancing, so when nodes join or leave, Swarm can move work and hand off state to keep the system stable. The library offers a global name registry, conflict resolution for name ownership, and hooks for reacting to membership changes. Its design embraces OTP principles, using supervised processes and fault-tolerant messaging to keep the registry resilient under failures. Developers can co-locate Swarm with their existing supervision trees to scale workers horizontally without writing custom clustering code. ...

Web based metrics, monitoring, and observer. Drop-in monitoring though web interface. Metrics endpoint (/metrics) for system monitoring. (Default: Prometheus) Monitoring automation through JSON API. Node management and discovery behind firewalls and load balancers. Easy to extend. Add custom metrics and pages for your project, just by adding them in the config. Just 3 lines of code to add pages/metrics for your library when users have :wobserver installed.
