Slash OpenAI image gen costs by 70% with smart caching and deduplication
Solo indie hackers building AI image tools lose 80% of revenue to skyrocketing OpenAI API costs, blocking profitability.
FluxSaver acts as a drop-in proxy between your app and OpenAI's DALL-E API, caching identical or similar image requests to avoid redundant generations. It uses perceptual hashing to detect near-duplicates, serving cached results instantly while tracking usage to ensure profitability. Indie hackers integrate it in minutes and reclaim lost revenue from repeated API calls.
