B2B data enrichment API providing person and company data at scale. PDL aggregates data from public sources to provide structured person profiles (employment history, education, skills, social profiles) and company data (headcount, funding, technologies used).

Cloud-native streaming SQL database that uses standard PostgreSQL wire protocol and SQL syntax to define streaming materialized views over real-time data sources (Kafka, Kinesis, databases). RisingWave continuously maintains materialized views as data flows in, enabling sub-second latency queries on streaming data without writing Flink or Spark jobs. Designed as a developer-friendly alternative to Apache Flink: SQL-first, PostgreSQL-compatible, and dramatically simpler to operate.

Role management library for Ruby on Rails — adds flexible role-based access control with resource-scoped roles. Rolify features: `rolify` macro on User model adds has_and_belongs_to_many :roles, `resourcify` on resource model enables resource-scoped roles, `user.add_role :admin` (global role), `user.add_role :editor, Agent` (class-scoped), `user.add_role :owner, @agent` (instance-scoped). Querying: `user.has_role? :admin`, `User.with_role :editor, Agent`. Integrates with CanCanCan and Pundit for authorization policy evaluation. Roles stored in roles table with optional resource_type/resource_id for scoping.

Rate limiting extension for FastAPI and Starlette — port of Flask-Limiter using the limits library. SlowAPI provides @limiter.limit() decorator for endpoint-level rate limiting with storage backends (in-memory, Redis, Memcached). Limits expressed as strings: '100/day', '10/minute', '1/second'. Supports key functions for per-user or per-IP limiting (default: client IP). Integrates with FastAPI's dependency injection and exception handlers. Agent API limiting example: @app.get('/agent/run') @limiter.limit('10/minute') for per-IP agent API rate limiting.

Hyperlocal weather intelligence API providing real-time conditions, forecasts up to 21 days, historical data, and severe weather alerts for any location.

Tyk API Gateway — open-source, self-hostable API gateway and management platform supporting REST, GraphQL, and gRPC with built-in rate limiting, auth, analytics, and developer portal.

MCP server wrapping Zillow real estate data APIs. Enables AI agents to query property listings, Zestimate valuations, neighborhood data, housing market trends, and rental pricing from Zillow's database — the largest US real estate platform.

Self-hosted open-source identity provider (IdP) supporting SSO, OIDC, SAML, LDAP, and OAuth 2.0. authentik provides a REST API for managing users, groups, applications, flows, and authentication policies. Used as a self-hosted alternative to Okta or Auth0 for teams wanting full control over identity infrastructure. Extensive customization via Python-based flows and expressions.

boto3 is the official AWS SDK for Python, providing Python-native access to all AWS services including S3, EC2, Lambda, DynamoDB, IAM, and hundreds more.

Thoughtbot's extensible admin dashboard generator for Rails — creates CRUD admin interfaces from model definitions with minimal configuration. Administrate features: Dashboard classes defining displayed fields, custom field types (BelongsToField, HasManyField, DateTimeField, UrlField), SHOW_PAGE_ATTRIBUTES / INDEX_PAGE_ATTRIBUTES / FORM_ATTRIBUTES arrays, search across configured attributes, sortable columns, pagination via Kaminari, filtering, custom action controllers inheriting from Admin::ApplicationController, and generator for dashboard files (rails generate administrate:dashboard Agent). Generates real Rails controllers and views (not DSL magic) — fully overridable. Less magical but more maintainable than ActiveAdmin.

Amazon Simple Notification Service — a fully managed pub/sub messaging service that fans out messages to many subscribers (Lambda, SQS, HTTP, email, SMS, mobile push) simultaneously.

Microsoft Azure's massively scalable object storage for unstructured data, supporting hot/cool/archive tiers, data lake analytics, and CDN integration.

Infrastructure as Code platform using real programming languages (TypeScript, Python, Go, C#, Java) instead of YAML/DSL. Deploy cloud resources (AWS, Azure, GCP, Kubernetes, 100+ providers) using familiar language features — conditionals, loops, functions, and type checking. Supports both declarative stacks and Pulumi Automation API for programmatic IaC from agent code.

Redis-backed background job library for Ruby — one of the original Ruby background job systems, uses Redis lists to store job queues and forks a new process per job. Resque features: Resque.enqueue(AgentWorker, agent_id) enqueues job, `def self.perform(agent_id)` class method processes job, named queues (@queue = :agents), Resque web UI (Sinatra dashboard) for job monitoring, retry via resque-retry plugin, and scheduler via resque-scheduler. Jobs are forked processes (memory-isolated but slower startup than Sidekiq threads). Sidekiq has largely superseded Resque for new projects but Resque is still widely deployed in mature Rails applications.

Opinionated PostgreSQL client for Node.js that enforces best practices. Slonik uses tagged template literals (sql`SELECT * FROM table`) with automatic parameterization — preventing SQL injection by design. Forces use of bound parameters for all values. Supports connection pooling, interceptors for logging/monitoring, type-safe query results with TypeScript, and strict result handling.
