24 alternatives to Key-Value Store API, No Subscription Needed
Hi HN, I often run into systems that can send email but cannot call a webhook directly I built a tool that creates an opaque email address @hook.echovalue.dev and forwards inbound messages as structured JSON to a configured endpoint. It can also call a webhook from a cron schedule, so small scheduled jobs do not need their own worker There are built-in formats for Slack, Discord, Teams, Telegram and custom JSON templates. Pricing is pay-as-you-go and intentionally low. It is mostly there as an abuse limit rather than a subscription model Docs:…

Vartiq▲97Hi 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…

Hi HN, I'm Daniel. I built a simple and straightforward API: you POST a JSON payload with your invoice data, and it returns a secure, presigned URL to a generated PDF. The goal is to make invoicing a single, reliable API call so you can get back to your main product. I also used this as a personal challenge to move away from my old LAMP stack background and build something new with Python/FastAPI, Next.js, and a serverless architecture on GCP and AWS. For the HN community, I've set up a promo code: HEYHN100 If you sign up, you can redeem it in your dashboard for 100 free credits (on top…

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…

Hey HN, stripe-no-webhooks is an open-source library that syncs your Stripe payments data to your own Postgres database: https://github.com/pretzelai/stripe-no-webhooks. Here's a demo video: https://youtu.be/cyEgW7wElcs Why is this useful? (1) You don't have to figure out which webhooks you need or write listeners for each one. The library handles all of that. This follows the approach of libraries like dj-stripe in the Django world (https://dj-stripe.dev/). (2) Stripe's API has a 100 rpm rate limit. If you're checking subscription status…

I have developed an application called "echoserver" and I would like to share its details on Hacker News. The purpose of "echoserver" is to simplify the testing of HTTP clients. It functions as an echo server, meaning it responds to requests by echoing back the received data. This allows users to simulate various server responses and test their HTTP clients accordingly. With "echoserver," users can generate custom responses by specifying the desired status code, headers, and response body. This flexibility enables thorough testing of HTTP clients and simplifies the process of verifying…

Hey all, some time ago I already presented my idea on HN with a landing page. Your feedback has been great and very valuable, we continued iterating on the product with customers and now have our first public version online. StorageRoom is a cloud-based CMS built specifically for Mobile Apps. If you have your own mobile app or if you are an agency or freelancer developing apps for others you can use it to create apps faster and to combine the advantages of native mobile applications with the ease of maintenance of websites. http://storageroomapp.com What do you think? Do you see other use…

Hi HN! Last year, I built LocalCan app in which you can develop apps using .local domains and Public URLs. Although it allows for testing webhooks too, I wanted to give back and create a free online tool specifically for that purpose! And so, I've made Webhook.cool Simply use your unique webhook URL to send any webhook to it from services like Shopify, Slack, Mailchimp, Trello, GitHub, PayPal, Discord, and Jira. Give it a try and let me know how if you have any feedback.
