Hookverge vs Lumen Playground

Hookverge is a private webhook-resilience lab for backend developers, platform engineers, consultants, and integration owners who need to reason about duplicates and partial failure before production traffic does it for them. Explore how event rate and provider failure translate into duplicate pressure, retries, backlog, and recovery obligations. KEY FEATURES - Retry-decay visualization - Event-rate and failure sensitivity - HMAC-SHA256 local fixture - Idempotency-window register - Persist-before-ack checklist - Dead-letter and replay ownership - Resilience artifact export - No endpoint or server required - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - No account, ads, analytics, tracking, IAP, or subscription Hookverge models recorded rates, attempts, and dedupe windows and generates local fixtures; it does not receive, send, replay, or validate production webhooks. Verify provider-specific signing, timing, ordering, retry, and recovery behavior against current documentation and controlled tests.

Lumen Playground is the living SwiftUI catalog for Lumen UI, a cross-platform primitive design system. Search the public component library, exercise real native controls, and compare Lumen's semantic light and dark themes directly on iPhone or iPad. Every example is built with the same LumenUI package available to application developers. Explore: • Foundations, actions, forms, feedback, data display, navigation, and native presentations • Interactive loading, disabled, selected, validation, overlay, and empty states • Native Dynamic Type, VoiceOver semantics, focus behavior, and platform conventions • Shared Lumen icons, colors, spacing, typography, and visual treatments • Direct links to implementation documentation and public support The catalog works without an account and does not include advertising, analytics, tracking, or data collection.
