The Moesif Origin/CORS Changer & API Logger Chrome extension allows developers to bypass Cross-Origin Resource Sharing (CORS) errors by overriding request and response headers such as Origin and Access-Control-Allow-Origin. It supports modifying headers to permit cross-domain AJAX, XMLHttpRequest, and fetch calls directly from the browser.

Additionally, the extension captures and logs API requests for debugging and analytics, sending data to your Moesif account. Features include real-time API monitoring, user behavior analytics, issue alerts, custom dashboards, and billing integrations. Designed primarily for development and testing, the tool includes domain whitelisting to limit usage and recommends disabling after debugging to avoid security issues. Moesif powers API observability for top companies, providing powerful insights into API usage and monetization.

User reviews

Users find the Moesif Origin/CORS Changer & API Logger extension highly effective in fixing CORS issues, especially for whitelisted hosts and local development. It is noted as the only working solution by some users in 2024. However, many mention that it requires submitting an email address to unlock advanced features and has limitations such as not working with fetch API, lack of web font support, and compatibility problems with newer browser versions. Some users request features like auto-disable on sites like YouTube to prevent interference.

Pros

Effectively fixes CORS issues for developers and works well for explicitly whitelisted hosts.
Simple to use with minimal configuration needed to bypass cross-origin restrictions.
Helpful for local development and quick testing scenarios, appreciated by users worldwide.
Works reliably for many users on different platforms and browsers.
Considered the only working solution by some users as of 2024.

Cons

Requires users to submit an email address to access advanced features, which some users dislike.
Does not work with fetch API requests reliably, limiting usefulness in some cases.
Lacks support for web fonts, as Access-Control-Allow-Origin: * is not automatically set, causing problems.
Has compatibility issues with newer versions of Chrome, macOS, and Microsoft Edge for some users.
Causes issues on certain sites (e.g., YouTube) where auto-disable functionality is desired but missing.

Recent reviews

Great. Only affects hosts that are explicitly whitelisted, very reasonable.
