I got tired of LLM observability tools getting acquired. So I built one that can't be.

A developer built an open-source LLM observability tool designed to prevent vendor lock-in after two major platforms, Helicone and Langfuse, were acquired within months of each other. The tool targets engineering teams in regulated industries like healthcare, finance, and government that require on-premises data handling.

Helicone got acquired. Langfuse got acquired. Two of the most trusted tools in the LLM observability space, gone within months of each other. I don't say this to criticize the founders. Building and selling is legitimate. But for engineering teams running AI in production — especially in healthcare, finance, and government where data cannot leave your servers — every acquisition is a crisis. So I stopped waiting for the next one.
