How do you manage environment variables for your projects or team?

Hey guys! I am looking for feedback for a tool I'm building called Onboardbase to solve this problem. While prioritizing security, Onboardbase takes a different approach making it easy to use and collaborative, eliminating the tradeoff between developer productivity and security to raise employee awareness and usher in a new era of secure-by-default, seamless development. https://onboardbase.com/ Questions: 1. How do you currently solve the problem? 2. What challenges do you face with your current solution? 3. Are you open to using a new tool or Onboardbase for this problem? 4. How much would you pay for a solution? 5. If you won't use this solution, why exactly? 6. What do you like and what do you not like about Onboardbase? 7. What do you think it's missing? 8. What question didn't I ask that's a game changer for you? 9. General thoughts. Thanks!
