Flowstack

Flowstack is an observability platform built specifically for LLMs in production. Whether you're a developer, product person, or a customer success specialist, Flowstack's intuitive dashboard and powerful data tables can help you understand your application's users and costs across any language model from OpenAI, Anthropic, Hugging Face, and more — all in one place. Implementing Flowstack just takes two lines of code in your API requests, also unlocking built-in tools such as remote cache, rate limits, and auto retries. Our Flex plan is completely free during beta, with Free and Enterprise tiers coming soon.
