Hooklistener is a modern tool designed for developers to test, inspect, and debug webhooks and HTTP requests efficiently.

While many webhook tools offer temporary disposable URLs, Hooklistener focuses on a professional workflow with persistence and collaboration at its core. It serves as a comprehensive middleware to visualize incoming data from services like Stripe, PayPal, Shopify, or your own APIs.

Key Features:

  • Real-time Inspection: Instantly view headers, body payloads (JSON, XML, Form), and query parameters in a clean, structured UI.
  • Team Collaboration: Unlike most alternatives, Hooklistener allows you to invite team members to shared workspaces so you can debug integrations together in real-time.
  • Request Replay: Easily retry failed webhooks or forward captured requests to your local development environment (localhost) for testing.
  • Permanent History: Your request logs are saved, allowing you to search and review past payloads without fearing they will disappear after closing the tab.
  • Granular Control: Filter and search through requests to find exactly what you need.

Hooklistener is the ideal alternative for developers who need more than just a temporary bin and require a reliable tool for building and maintaining API integrations.

RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ€” not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.

A free tier includes 400 exercises with flat-style 512ร—512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ€” exclusive to that tier.

Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.

Questions & Answers

As answered by people managing Hooklistener and RepDB.

Who are some of the biggest customers of your product?

Hooklistener's answer

Agile SaaS Startups

E-commerce Development Agencies

Fintech Integration Teams

Independent API Developers

What makes your product unique?

Hooklistener's answer

Hooklistener combines real-time webhook inspection with robust team collaboration and monitoring features. Unlike disposable tools, we offer permanent request history, shared workspaces for teams, email testing, and downtime alerts, making it a complete debugging ecosystem rather than just a temporary bin.

RepDB's answer:

RepDB is sold as a one-time download, not a metered API โ€” you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.

Why should a person choose your product over its competitors?

Hooklistener's answer

Choose Hooklistener if you need reliability and teamwork. While competitors offer temporary URLs that delete your data upon closing the tab, Hooklistener provides a persistent workspace where history is saved. Itโ€™s built for professionals who need to replay requests, share debug sessions with colleagues instantly, and monitor their endpoints for silence or errors.

RepDB's answer:

Most alternatives are subscription APIs โ€” you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.

How would you describe the primary audience of your product?

Hooklistener's answer

Our primary audience consists of Backend Developers, QA Engineers, and technical teams building integrations with third-party APIs (like Stripe, Shopify, or PayPal). It is ideal for agile teams that need to debug asynchronous events collaboratively without setting up complex local infrastructure.

RepDB's answer:

Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.

What's the story behind your product?

Hooklistener's answer

Hooklistener was born out of frustration. As developers, we were tired of using "disposable" webhook tools that lost critical data whenever we refreshed the page or closed the browser. We needed a tool that treated webhook debugging as a serious part of the development workflowโ€”with persistence, security, and the ability to work together as a team. So, we built it.

RepDB's answer:

RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

Which are the primary technologies used for building your product?

Hooklistener's answer

Hooklistener is built on a modern, high-performance stack utilizing Real-time WebSockets for instant data delivery. We use a scalable cloud infrastructure to ensure data persistence and low-latency processing, ensuring that every webhook is captured and displayed the millisecond it arrives.
