Hmm... I'm relatively new, but I've been using utility scripts in a run/ directory in my project that will spin up containers based on compose, and that includes dev containers volume mapped to my host directories in a given project. It's worked pretty well for me at least. Similar to TFA, it's been able to configure services in the compose file, update the utility scripts and diagnose problems in the services in runtime and dev modes respectively. No browser integration though, but I'm sure playwright/puppeteer work.
