Serious Platforms for Serious GPT Builds...What’s Working?
Quick question for the crew here: I’m deep in the custom GPT game right now and looking for real alternatives to OpenAI’s hosted setup. I’ve built a suite of tools, all of which are designed for marketers to tighten up funnels, rewrite swipe files, and sharpen ad scripts. Luvable was my main build spot, but to be blunt, it’s hit a ceiling. The complexity of one of my custom GPT tools, with its layered rewrite logic, tone/trigger overlays, and strict structure parsing, has exposed its limits. Feels like I’m duct-taping a framework that can’t fully handle modular, high-control tools. What platforms are you using—or would seriously recommend for: - Full control (no OpenAI paywall/UI limits) - Solid API access + deep prompt chaining - Scalable hosting (I want to sell these, not just play) - Flexibility for complex workflows (not just “simple prompt + output” stuff) Bonus points if it supports white labeling or embedding. if you’ve actually moved your GPT out from the OpenAI ecosystem and can vouch for it, I’m all ears. Appreciate the wisdom.
