Props

Props AI is the open-source proxy that lets you keep a hawk eye on every OpenAI call without the headache of building your own log system. I mean, if you're building a chatbot, a content generator, or any GPT-powered SaaS, you've probably spent hours chasing down over-charged prompts. Props solves that by logging tokens, costs, response times, and errors in a tidy dashboard that's ready to ship in five minutes.

Key features? We're talking real-time analytics, automatic cost tracking, built-in Stripe integration for pay-per-use billing, and an API that plugs right into your stack. Because it's open source, you can tweak the code to fit niche workflows or add custom metrics. I've seen teams cut their spend by 30% once they could see where the waste was happening.

Who needs this? If you're a developer building AI-powered products, a startup scaling OpenAI, or an enterprise auditing usage, Props is your sidekick. Think chatbots, content generators, recommendation engines-any app that talks to GPT and wants to know what's eating the budget. What makes Props stand out?

Unlike generic logging tools, it's laser-focused on OpenAI and comes with a monetization layer that works out of the box. No extra middleware, no guesswork. The community is active, so if you hit a snag, you'll find help faster than you can say "token spike." Ready to stop guessing your API costs? Set up the cloud proxy, watch the insights roll in, and start billing users the way you actually want to.

It's free to self-host, and the cloud plans start at $47/month-so you can test before you commit.
