Webhooker – An Open-Source Webhook Processing Platform (Rust)

I built and open-sourced Webhooker, a lightweight platform for ingesting, validating, and processing webhooks from third-party services. Inspired by the challenges of building custom webhook logic for each integration, I decided to extract common patterns into a reusable system.

I built Webhooker using Rust, designed to be fast, secure, and extensible. It solves the common pain point of handling asynchronous webhooks from services like Stripe, GitHub, and Twilio — where retries, signature validation, and logging are often scattered across applications.

Key features include:

High-performance request ingestion using Actix Web

Pluggable signature validation strategies (e.g., HMAC, RSA)

Persistent event storage with PostgreSQL for durability and replay

Retry logic with exponential backoff and dead-letter support

Internal event bus that can forward webhook payloads to queues or custom handlers

What makes Webhooker powerful is its modular core — developers can extend it to plug in custom business logic or forward payloads to services like RabbitMQ, Kafka, or even internal APIs.

It’s ideal for teams building microservices who want a dedicated, observable, and secure webhook gateway without coupling webhook logic directly into app services.

Key Skills: Rust, Actix Web, PostgreSQL, Webhook Security, Async Retry Logic

Problem Solved: Centralized and standardized webhook handling across multiple services with high performance and observability.
