Features & Capabilities

API Response Comparator helps developers and QA teams compare JSON API responses across Dev, QA, and Prod directly from a browser popup. Paste JSON, upload response files, fetch HTTPS API URLs, or import safe cURL commands, then inspect added, removed, changed, and type-changed fields.

The first populated environment in Dev, QA, Prod order becomes the baseline. Any two environments are enough, so you can compare Dev vs QA, QA vs Prod, or all three together.

Features include:

Manual JSON paste, format, upload, and clear controls
Direct HTTPS URL fetch comparison
Safe cURL parsing with structured browser fetch execution
Ignore leaf fields and volatility-based ignore suggestions
Contract-change alerts
Count filters and path search
Table and color-coded JSON tree views
Copy, JSON download, and Excel-compatible export
Full reset with in-flight request cancellation
Light and dark themes

The extension runs locally in the browser. It does not include analytics, ads, tracking, or a remote backend.

Is API Response Comparator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

API Response Comparator requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

API Response Comparator is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
