  • KILLSWITCH
    So my first instinct is to setup some sorta feature-flag thing within a CMS so managers can flip the boolean, I'm exploring getunleash.io and GrowthBook.io and we already use Contentful.com within the app but they're saying they "really don't think we need to use any third party thing for a killswitch"...

  • Need your opinion
    We are an Open Source Feature Flagging solution called Unleash, and we are looking to get some feedback from the community on a decision we are trying to make. We are considering offering our developers the option to either write technical content through a Community Content Program for us for a $200 fee, or to donate that amount to charity.

  • Free QA-type scripting tools?
    Headless Recorder from Checkly might be a cool addition and it supports Playwright and Puppeteer 🙌. Source: over 1 year ago

    Checklyhq.com - Checkly is the API & E2E monitoring platform for the modern stack: programmable, flexible and loving JavaScript. Generous free tier for devs. - Source: dev.to / over 1 year ago
  • How to stay one step ahead of errors and downtime as you scale up your business
    At FINN we use Checkly once again to run our scheduled E2E tests. Some teams also use a combination of Make and Apify to run scheduled E2E tests on smaller projects. - Source: dev.to / over 1 year ago

    This is a good area that needs to be fleshed out, so far the best solution I've found is https://checklyhq.com/ Playwright as a service + other monitoring checks is amazing. - Source: Hacker News / almost 2 years ago
