   Vartiq▲97

   Hi HN, I’ve been working on Vartiq, a plug-and-play Webhook as a Service platform. What it is: Sending outbound webhooks reliably is a pain many SaaS products face. You end up building: - Delivery logic with retries and exponential backoff - Dead-letter queues for failed deliveries - Observability pipelines for logs and debugging - Auto-scaling infra to handle spikes in events Vartiq aims to take all of that off your plate. Key features: Zero lost events – reliable delivery with auto retries Dead-letter handling out of the box Live observability – dashboards, delivery logs, and metrics…

    Sidequest.js – Background jobs for Node.js using your database▲89

    Hey HN, I'm the maintainer of node-cron (5M+ downloads/month), and I recently built Sidequest.js, a background job runner for Node.js inspired by Oban (Elixir) and Sidekiq (Rails). It solves some common problems I saw with libraries like node-cron: - Jobs don’t block your API: they run in isolated worker threads - No Redis or vendor lock-in: use Postgres, MySQL, SQLite, or MongoDB - Supports retries, uniqueness, concurrency, snoozing, prioritization - Comes with a CLI and a simple dashboard - Works great in monoliths and doesn’t require extra infra Quick start (no signup needed):…

    Webhooks for platforms that do not natively support them▲79

    Hello HN, We’d like to show you our project — Nohooks[0]. The aim is to add webhooks to platforms that do not natively support webhooks. We really believe many APIs can provide a better developer experience by providing webhook notifications to enable us to automate more things. Nohooks works by intelligently polling the integrated platform's APIs, determining if a change has occurred, and generating webhook events. Nohooks currently supports webhooks from Notion’s Databases, Render’s Services & Deployments, and DigitalOcean’s Droplets. We will add more in the coming days and improve the…
