How are you all handling giant prompts in code?

Hello everyone,

While building one of my AI projects I realised half my backend files were basically giant prompt strings taped together and any change that I wanted to make to a prompt required a full redeployment cycle, which proved to be extremely painful to do all the time.

I kept running into this across multiple projects, especially when prompts kept evolving. It felt like there was no clean way to manage versions, experiment safely, or let a non-dev teammates suggest changes without risking chaos. And honestly, it gets even worse as you try to scale beyond a small SaaS setup.

Eventually I built a small prompt management tool for myself to add it as part of my tech stack. After showing it to a few friends they motivated me to released it as a tool and make it available commercially. So I did and recently I released an MVP version of it, with a few enterprise ready features like audit logs and team access controls. I know that there are some available prompt management tools both open source and paid, but they all seemed a bit too overkill and complex for my use case or just didn't have good version control and a/b testing.

I’m aiming to grow it into something that actually supports more serious/enterprise workflows, if you work with prompts a lot, I’d really love your thoughts, what sucks, what you wish existed, or if you want to try it and tell me where it falls short.
Here’s the link if you’re curious: vaultic.io

Currently some of the futures that it offers are:

  • Git like versioning
  • A/B Testing
  • Audit and API logs
  • Analytics
  • Role based access
  • SDK's & API
