Experiential

Experiential is an open-source AI gateway and model router that unifies access to hosted, self-hosted, and bring-your-own-key language models through an OpenAI-compatible API. It supports more than 1,000 marketplace models while allowing developers to connect their own providers. The platform controls which users and agents can access specific models and how much they can spend. It collects execution traces to evaluate model performance, costs, and response speed. Developers can optimize custom routing strategies using real agent traffic and simulation workflows. It also supports fine-tuning specialized open-source models based on collected interactions. Experiential integrates with coding agents such as Claude Code, Codex, and Cursor and provides configurable telemetry, access controls, and local deployment options.
