Net::LDAP for Ruby (also called net-ldap) implements client access for the Lightweight Directory Access Protocol (LDAP), an IETF standard protocol for accessing distributed directory services. Net::LDAP is written completely in Ruby with no external dependencies. It supports most LDAP client features and a subset of server features as well. Net::LDAP has been tested against modern popular LDAP servers including OpenLDAP and Active Directory. The current release is mostly compliant with earlier versions of the IETF LDAP RFCs (2251-2256, 2829-2830, 3377, and 3771). Our roadmap for Net::LDAP 1.0 is to gain full <em>client</em> compliance with the most recent LDAP RFCs (4510-4519, plutions of 4520-4532).

Koala is a lightweight, flexible Ruby SDK for Facebook.

Build AI features the Ruby way. A delightful Ruby AI framework that feels at home in Rails: switch models without rewriting your code, then scale from a single call to production agents, RAG, and workflows.

Works with OpenAI, Azure, Anthropic, Google Gemini, Vertex AI, AWS Bedrock, xAI, Cohere, DeepSeek, Mistral, Perplexity, OpenRouter, ElevenLabs, Deepgram, Ollama and GPUStack (local models), and any OpenAI-compatible API. Plain Ruby with a small set of runtime dependencies.
