What ModiNet Does

ModiNet lets you manage browser networking rules in one place for testing and debugging.

Real Developer Scenarios

“Backend not ready? Use Mock API.”

“Need to test slow network? Inject delay.”

“Testing staging vs production? Redirect instantly.”

“Need to override auth headers? Modify safely.”

Redirect

Redirect requests by URL or regex pattern and choose resource types like script, stylesheet, main_frame, XHR, and image.

Mock API

Return mock response bodies in browser with URL pattern, method filter, query include option, and body type controls.

Header Modify

Set, append, or remove request/response headers with filters for method, resource type, and query handling.

Delay Injection

Delay fetch/XHR calls by milliseconds. Abort support is handled and synchronous XHR is intentionally excluded.

Rule Management

Global enable/disable toggle, sorting/filtering, and JSON export/import for repeatable setup.

Onboarding Demo

Sample redirect/mock/delay rules are auto-installed so you can test behavior quickly.

Limitations and Notes

Known constraints are listed below so you can evaluate where ModiNet fits best before installation.

Limitations

Mock API supports response body only. Status codes and custom headers are not applied in mock mode.

Permissions

Uses DNR and storage-related permissions including host access to apply and persist rules.

Automation API

Background message API is available but disabled by default and protected by token and allow-list checks.

Usage Flow

Open the Options page and configure Redirect, Mock, Header, or Delay. Save and enable a rule to apply it immediately.

Data is saved in chrome.storage.local. The free plan supports up to 20 dynamic rules.

Ready to Install

Install ModiNet and debug browser traffic in minutes

Start with sample rules, verify behavior quickly, and iterate API testing workflows without local proxy setup.
