Kiosk vs Webhook Management

Kiosk is a free, open-source PDF reader for web, desktop, mobile, and browser extensions. It renders PDFs and offers full-text search with highlighted results, page thumbnails, zoom, and light, dark, and night display modes. Its Chrome extension adds highlighting, underlining, strikethrough, drawing, shapes, and text annotations. The project says PDFs stay on the device, with no telemetry, cloud processing, or account requirement. Android works offline after installation, and the extension release notes also state that offline use is supported. The web app can run locally or be deployed through GitHub Pages as a self-hosted instance. Desktop apps can open PDFs directly and associate Kiosk with PDF files; the extension can intercept PDFs opened in Chrome. The extension supports Chrome 88+, Edge 88+, and Brave, but not Firefox or Safari. The project is released under the MIT License. Its Android release is an early alpha, and the macOS app is ad-hoc signed but not notarized, so Gatekeeper may warn on first launch.

Webhook Management sends and tracks webhooks through a dashboard and REST API. Users can register and test endpoints, route selected event types, inspect deliveries, and replay historical events. Failed deliveries are retried with configurable exponential backoff, and events remain stored until delivery succeeds or they are manually cancelled. Each webhook is signed with HMAC-SHA256 so recipients can verify authenticity and detect tampering. The dashboard tracks delivery success, latency, and endpoint health, with failure alerts; consistently failing endpoints are disabled automatically. The product page states a 99.99% delivery rate and average latency under 200 ms. The API covers endpoint creation, sending and listing events, retrying events, and checking endpoint health. The maker describes use in SaaS integrations, payment events, event-driven architectures, and partner notifications. Starter is free for up to 10,000 API requests per month and includes seven-day log retention. Pro is billed monthly for usage, with unlimited API requests and Webhook Management listed at €0.0001/delivery. The Webhook Management plan is listed at free, starting at $0.0001 per event, with up to five retry attempts included; additional retries are charged. The product lists 30-day retention.
