DevTools

I developed an obsession! Here, I said it.

For the last 3 months, I've been spending every afternoon building DevTools. It started with utilities that I use for testing. Then I needed something simple to migrate from Cypress to Playwright. Then I was learning Regex, etc. In total it now features 85 tools.

All tools are ad free and free to use. No catch. I just wanted to build something that others would use.
