To get the most out of these free tools, make sure to take advantage of DevTools' local payment methods, which support bKash, Nagad, Rocket, and card payments in USD. This flexibility ensures you can use your favorite tools without worrying about currency conversions.

How it compares

While there are many excellent free online developer tools available, such as CodePen, JSFiddle, and Repl.it, these alternatives often lack the depth and variety of DevTools' suite. With its unified approach to dev tool development, DevTools offers a more comprehensive solution for developers on-the-go.

DevTools is free to start with no card. Pro is $4/mo monthly, $34/yr yearly, or $79 once once for lifetime access. Pay by card in USD, or with local methods like bKash, Nagad and Rocket.
