Versions:
hookwarden is an open-source command-line tool published by Hookwarden, currently at version 0.3.1, with a single recorded version in the catalog. It is a webhook signature-verification audit tool designed to detect signature-verification bugs in webhook handler code. Falling within the software security and developer tooling category, hookwarden targets a common weakness in webhook integrations: handlers that fail to properly verify the cryptographic signatures attached to incoming webhook requests, which can leave applications exposed to forged or tampered payloads. The tool supports codebases written in JavaScript, TypeScript, and Python, making it relevant to a broad range of server-side projects that consume webhooks from third-party services. As a CLI utility, it can be run directly from a developer's terminal and fits naturally into existing local workflows, continuous integration pipelines, or pre-deployment review processes. According to its published description, hookwarden is able to find issues in under five minutes, positioning it as a fast audit option for teams that need quick feedback on the correctness of their webhook verification logic. A notable characteristic of the tool is that it operates with zero off-machine traffic, meaning the analysis is performed entirely locally without sending code or data to external services; this makes it suitable for environments with strict privacy, compliance, or network restrictions. Typical use cases include auditing newly written webhook handlers before release, reviewing legacy integrations for latent verification flaws, and periodically scanning codebases as webhook endpoints evolve. Because it is open source, users can inspect the tool's behavior and adapt it to their needs. With version 0.3.1 as its only cataloged release, hookwarden remains an early-stage project, and users evaluating it should consult the publisher's documentation for installation instructions, supported signature schemes, and details about future version releases.
