Development Tools at Avenzo

Practical utilities for real web-development workflows.

Avenzo’s developer tools focus on public website diagnostics and browser-side utilities. They support debugging and QA without pretending to have access to private server configuration.

Public-data only

Technology detection and diagnostics are based on HTML, assets, headers and URLs exposed by the website.

Explainable results

Detected technologies and problems show the public signal that led to the result.

Built for developers

Use the tools for debugging, QA, migrations, rebuild planning and technical discovery before implementation.
