I was snooping around to find what Postman’s competition looks like and I came across a tool called the Advanced REST Client - it’s an Electron app, open sourced and available on GitHub.

Basically I compared the two tools by checking the features they have and trying them out.

While there is a lot of overlap this tool is still no match for Postman, but for those with very simple API testing needs it might come in-handy. ARC has a very nice looking interface, if you’re into minimalism.

I’ve always wanted to try out mitmproxy. It’s a favourite tool of one of my colleagues.

I use Charles as my default proxy tool. But I wanted to see what the fuss was all about.

Selenium and Playwright

Pros and cons

I will probably use Selenium till the day I leave my current job, but I really like how quick Playwright is to setup, and run. It is also a very quick driver.
