We're always looking for new ways to improve our effectiveness as frontend developers. We want to pick the right tools to get the job done. We want to have a fully equipped browser, to troubleshoot any tricky bug that comes our way.

Browser extensions have been around for a while, making their way into our development workflow in many different shapes. We can think of extensions as development companions.

In this article, we would like to share a few of them, that in our opinion, provide valuable assistance for frontend developers.

If you're debugging HTTP requests or mocking APIs for frontend development, you've likely considered both tweak and Mock Service Worker (MSW). While both tools allow you to intercept and modify network traffic, they approach the problem from completely different angles. tweak is a lightweight browser extension; MSW is a code-level library that integrates directly into your project. Understanding their differences will help you pick the right one for your workflow.

If you're debugging HTTP requests and network issues, you've likely considered both tweak and Proxyman. Both tools let you intercept, inspect, and modify network traffic—but they approach the problem from different angles. tweak is a lightweight browser extension; Proxyman is a full-featured desktop proxy application. Understanding their differences will help you pick the right one for your workflow.

If you've been searching for a way to mock HTTP requests in your browser, you've likely come across both tweak and Requestly. Both tools let you intercept and modify network requests without touching your backend, but they approach the problem differently. This post breaks down what each tool does well and when you should reach for one over the other.

Another year, another existential question: will AI tools/agents or AI browsers replace browser extensions? Spoiler alert - not yet. But let's talk about what actually happened in 2025.

It's possible to pin a Chrome extension in the Chrome browser simply following the steps:

1. Open the Chrome browser.
2. Click on the "puzzle piece" icon in the top right corner of the browser.
3. Locate the extension you want to pin.
4. Click on the "pin" icon next to the extension you want to pin.

Below an imagine and a short clip to illustrate the steps.

Closing on 2024, we’re thrilled to share the milestones and achievements that made this year unforgettable for Tweak Extension. With +65% more active users and more than 48M requests intercepted! Here’s a look at some 2024 numbers:

HTTP Archive, commonly known as HAR, is a file format used by developers to capture and store network communication data between a web browser and a website. This valuable tool provides a detailed record of the interactions between a user's browser and the various web elements that compose a site. But why do developers find HAR files indispensable, and what information do these files encapsulate?

It's really hard to express the power of tweak just through our documentation. Some use cases fall through the cracks. We got some recent feedback on users searching for a way to modify URL query parameters and not being able to find it in tweak. This short "how to" article explains how you can manipulate the URL and its query parameters with tweak in just 3 simple steps.

We are thrilled to announce the exciting launch of tweak in the Microsoft Edge Browser! With this powerful tool at your fingertips, you can define rules, capture HTTP requests, and receive customized mocked responses directly within your browser. Say goodbye to cumbersome server setups and welcome a more efficient and streamlined development process.
