Packages

Lightweight open-source publish-subscribe messaging system with optional JetStream persistence layer for at-least-once delivery and replay.

LLM fine-tuning platform that captures your OpenAI API calls and turns them into fine-tuning datasets automatically. OpenPipe intercepts prompts and completions from your production application via a drop-in SDK replacement, filters for high-quality examples, and fine-tunes smaller models (Llama, Mistral) to match performance at 10-100x lower cost. Purpose-built for production cost reduction: replace expensive GPT-4 calls with fine-tuned small models.

Passage by 1Password provides a passkey-first authentication API that lets agents register and authenticate users via FIDO2 WebAuthn biometrics with optional magic link fallback, backed by 1Password's security infrastructure.

Fast and affordable cloud web crawler and scraper API built on a Rust engine that returns AI-ready Markdown output, supports JavaScript rendering, and offers credits-based pricing optimized for LLM data pipelines.

Uploadcare provides a file upload and CDN platform with REST APIs for programmatic file ingestion, storage management, and on-the-fly image/video transformations via URL-based processing directives.

Collaborative platform for building, testing, and deploying AI-powered chat and voice agents. Voiceflow provides a visual drag-and-drop builder for conversation flows, integrates with LLMs (GPT-4, Claude, etc.) for AI responses, and offers a Dialog Manager API for deploying agents to any channel (web chat, Twilio, WhatsApp, etc.). Used by enterprise teams to build customer service bots, product support agents, and interactive voice response (IVR) systems with non-technical collaboration.

X (Twitter) MCP server enabling AI agents to interact with X's social platform — posting tweets and threads, searching tweets, retrieving user timelines, fetching engagement metrics, and integrating X's real-time social data into agent-driven social media management and monitoring workflows.

Amazon RDS REST API — managed relational database service enabling agents to provision, configure, backup, and scale PostgreSQL, MySQL, MariaDB, Oracle, and SQL Server instances, and manage Aurora clusters without infrastructure management.

Async Python MongoDB ODM with Pydantic validation — Document-Object Mapper built on Motor + Pydantic v2. Beanie features: Document class (Pydantic BaseModel + MongoDB collection), async CRUD (await Agent.insert(), await Agent.find_one()), query builder (Agent.find(Agent.status == 'idle')), aggregation expressions, link references (Link[Task] for relations), lazy loading, Settings class for collection/index config, migrations via beanie-migration, and built-in JSON serialization. The FastAPI-native MongoDB ODM that makes agent document validation and persistence ergonomic.

Multi-language authorization library with a unified policy model supporting ACL, RBAC, ABAC, and custom access control models. Casbin uses a PERM (Policy, Effect, Request, Matchers) meta-model — define access control in a .conf model file and policies in a .csv or database. Single policy model runs across Go, Node.js, Python, Java, PHP, and Rust via consistent Casbin ports. Used for complex multi-role, multi-resource permission systems.

Language-agnostic background job server with a simple wire protocol (RESP-based). Faktory provides the job server component while language-specific workers connect to execute jobs. Unlike Redis-backed libraries (BullMQ, Celery, Sidekiq), Faktory is a standalone server purpose-built for job queuing — not general-purpose caching. Created by Mike Perham (creator of Sidekiq). Workers available for Ruby, Python, Go, Node.js, Java, Rust, and more. Web UI for monitoring. Faktory Pro/Enterprise adds batches, unique jobs, and more.

Highlight.io — open-source, full-stack observability platform with session replay, error monitoring, and log management in a single tool, with REST API for programmatic access to errors and sessions.

Low-level async HTTP/1 and HTTP/2 library for Rust. Hyper is the HTTP foundation that powers reqwest (HTTP client), Axum (server), and many other Rust HTTP tools. Hyper 1.x provides a minimal, correct, and fast HTTP implementation without built-in routing or higher-level abstractions. Used directly when you need maximum control over HTTP behavior — connection reuse, streaming, protocol details — or when building your own HTTP framework.

Open-source framework for building LLM-powered applications and agents, providing composable abstractions for chains, memory, tools, retrievers, and agent orchestration. LangSmith provides hosted tracing, evaluation, and dataset management via REST API.

Leadfeeder (Dealfront) Website Visitor Intelligence REST API for B2B website visitor identification and account intelligence platform. Enables AI agents to manage website visitor company identification and enrichment automation, handle account-level visit scoring and lead qualification, access page-level behavior and content consumption data per company, retrieve visit history and company engagement trend tracking, manage CRM lead creation from high-intent website visitors, handle integration with Salesforce, HubSpot, and Pipedrive for visitor-to-lead routing, access filtered visitor feeds by industry, company size, and location, retrieve B2B contact data for identified visiting companies, manage custom feed creation for specific ICP segments, and integrate visitor intelligence with marketing automation and ABM platforms.

Full-stack web framework for Rust compiled to WebAssembly. Signals-based reactive UI similar to SolidJS but in Rust. Supports CSR (client-side rendering), SSR (server-side rendering), and SSG (static generation). Server functions compile to both client and server — no separate API layer needed. Compiles to ~100KB WASM vs megabytes for JS bundles.

Open-source server-side data processing pipeline that ingests data from multiple sources, transforms it, and ships it to Elasticsearch or other outputs.

Logto is an open-source Customer Identity and Access Management (CIAM) platform providing OIDC-compliant authentication, built-in social login connectors (20+ providers), multi-tenancy, RBAC, and SDKs for 20+ platforms — available as self-hosted or Logto Cloud with a built-in admin UI.

Lusha API — B2B contact data enrichment API for finding professional email addresses and phone numbers, enriching lead profiles with company data, and verifying contact information.

Multi-vendor SSH library for network device automation — connects to routers, switches, and firewalls via SSH. Netmiko features: ConnectHandler for device connections (device_type, host, username, password), send_command() for show commands, send_config_set() for configuration, enable() for privileged mode, save_config(), textfsm/genie integration for structured output, connection pooling, timeout handling, expect_string patterns, 50+ vendor device types (cisco_ios, cisco_nxos, juniper_junos, arista_eos, paloalto_panos, linux), BaseConnection context manager, and SSH key auth. Python SSH automation for network infrastructure management in agent network operations.
