Packages

Postgres-native search engine built on Elasticsearch's BM25 algorithm, implemented as a PostgreSQL extension. ParadeDB adds full-text search (pg_search extension with BM25 ranking), vector search (pg_vectorize), and hybrid search capabilities directly inside PostgreSQL — eliminating the need for a separate Elasticsearch cluster. Search queries run as standard SQL with PostgreSQL's ACID guarantees, joins, and type system. 'Elasticsearch alternative for PostgreSQL users'.

SEON fraud intelligence REST API for e-commerce merchants, fintech companies, and online platforms to detect fraudulent users, assess risk signals, and prevent account takeover, payment fraud, and bonus abuse — combining email intelligence, phone intelligence, IP analysis, device fingerprinting, and social media lookup to build a digital footprint risk score for each user — enabling automated fraud prevention, user risk scoring, and suspicious activity detection through SEON's machine learning fraud detection platform. Enables AI agents to manage email intelligence for email domain, breach, and social media profile automation, handle phone intelligence for phone carrier, type, and social presence automation, access IP analysis for IP geolocation, proxy/VPN/Tor detection automation, retrieve device fingerprinting for browser and device identity automation, manage AML screening for basic PEP and sanctions check automation, handle fraud scoring for composite risk score calculation automation, access transaction monitoring for payment fraud signal automation, retrieve case management for fraud investigation and review automation, manage whitelist/blacklist for trusted and blocked entity management automation, and integrate SEON with payment gateways, onboarding flows, and risk platforms for layered fraud prevention automation.

GraphQL-first headless e-commerce platform built on Django/Python with a rich webhook system and extensible app framework.

Declarative GUI toolkit for Rust (and C++/JavaScript) with a proprietary .slint DSL for UI definitions. Targets embedded systems (microcontrollers), desktop applications, and web. Slint's custom DSL enables design-time previewing and separation of UI from logic. Positioned as a modern Qt alternative for Rust. Renders using custom GPU-accelerated renderer (femtovg or skia).

Lightweight progressive AJAX HTTP library for Node.js and browsers. SuperAgent provides a fluent chainable API for HTTP requests with built-in JSON/form parsing, file upload, query string serialization, response type detection, and retry support. Still widely used for API testing in Mocha/Chai stacks via supertest (HTTP testing against Express apps without a running server).

Shell scripting library for Python — provides Pythonic API for running subprocesses, building pipelines, and remote execution. plumbum features: local['cmd'] for local commands, local.path for path manipulation, | operator for pipelines, & for background execution, remote machines via SshMachine, FG/BG/TEE run modes, command composition (ls['-la'] | grep['py']), retcode handling, working directory context manager (local.cwd), environment variable context manager (local.env), CLI application framework (plumbum.cli), and cross-platform path handling. Bridges gap between shell scripts and Python programs.

Full-featured GraphQL server with schema-first resolver pattern, Apollo Studio integration, DataLoader for N+1 prevention, and built-in support for Apollo Federation.

Periodic task scheduler for Celery — runs cron-like scheduled tasks via Celery Beat process. Celery Beat features: @shared_task with beat_schedule in celery.py configuration, crontab() for cron expression schedules (every Monday at 9am), timedelta for interval schedules (every 10 minutes), django-celery-beat for DB-backed schedules editable via Django admin, dynamic schedule modification without restart, PeriodicTask model for programmatic schedule management, clocked() for one-time scheduled tasks, solar() for sunrise/sunset schedules, and timezone support. Separate celery beat -A myapp process runs alongside Celery workers for agent scheduled task execution.

Async Python web crawler optimized for LLM pipelines that renders JavaScript, extracts clean Markdown, and supports structured data extraction via CSS/XPath/LLM strategies.

Cloud API for automated video and image generation from templates. Creatomate provides a template editor (UI or JSON-based) and a REST API to render videos/images with dynamic content — variable text, images, colors, and audio. No need to set up rendering infrastructure (FFmpeg, Chrome, Lambda) — Creatomate handles all rendering server-side. Used for social media automation, personalized video generation, and content workflows.

Cyclr REST API for embedded integration platform as a service (embedded iPaaS). Enables AI agents to manage integration template creation and deployment, handle connector and cycle (workflow) library management, access end-user integration activation and configuration, retrieve integration run status and error monitoring, manage multi-tenant integration deployment across SaaS customers, handle OAuth connection management for third-party services, access connector library with 500+ pre-built integrations, retrieve integration analytics and usage metrics, manage white-label integration marketplace for SaaS products, and embed integration capabilities into SaaS platforms for end-user automation.

Safe, extensible ORM and query builder for Rust. Diesel generates Rust types from your database schema and provides a compile-time verified query DSL — if your query compiles, it's valid SQL. Unlike SQLx (raw SQL with macros), Diesel uses a typed query builder (users.filter(name.eq('Alice')).select(id)) that prevents schema mismatches at compile time. The most mature Rust ORM.

PyTorch-based OCR library supporting 80+ languages with GPU acceleration, returning text with bounding boxes and confidence scores from images.

Google Cloud NLP API for sentiment analysis, entity extraction, syntax analysis, content classification, and entity sentiment on text.

Provides geocoding, reverse geocoding, routing, matrix routing, map tiles, places search, geofencing, and fleet telematics APIs for building location-aware applications and agent workflows.

Fast tokenization library for NLP — Rust-backed tokenizer with Python bindings for training and using tokenizers. HuggingFace Tokenizers features: AutoTokenizer (loads pretrained tokenizer from Hub), encode/decode for single texts, batch encoding, special tokens ([CLS], [SEP], [PAD]), truncation and padding, fast tokenization (10-100x faster than slow tokenizers), offset mapping for token-to-character alignment, custom BPE/WordPiece/Unigram tokenizer training, and integration with HuggingFace Transformers. Used for preparing agent text for LLM inference and fine-tuning.

High-performance ML research framework — NumPy-compatible array library with autograd, JIT compilation, and hardware acceleration. JAX features: jax.grad() for automatic differentiation, jax.jit() for XLA compilation (10-100x speedup), jax.vmap() for vectorization, jax.pmap() for multi-device parallelism, jax.numpy (jnp) NumPy-compatible API, functional programming model (pure functions required), random number via jax.random.PRNGKey (not stateful), and TPU/GPU/CPU backends. Preferred framework for ML research — neural network libraries Flax and Optax build on JAX. Used by Google DeepMind for research.

LangSmith REST API — LLM observability, tracing, and evaluation platform enabling agents to log runs, trace multi-step chains, evaluate outputs with datasets, and monitor production LLM applications for latency, cost, and quality.

Email marketing platform designed specifically for SaaS companies, combining transactional and marketing emails in a single tool with a clean REST API for contact management and event-triggered campaigns.

Multimedia streaming framework for Elixir built on the BEAM. Membrane provides a composable pipeline model for processing audio/video streams — ingest from RTMP/WebRTC/HLS, transcode, mix, and output to multiple targets. Uses the same GenStage-inspired pipeline model as Broadway but for multimedia. Supports WebRTC peer connections, RTMP ingest (for OBS-style streaming), HLS output, MP4/Matroska muxing, Opus/AAC audio, and H264/H265 video. Used by Jellyfish (WebRTC conferencing server) and VideoRoom.
