AccordKit is the open, developer-first tracing SDK for modern AI and ChatGPT-integrated apps.
While commercial platforms like Braintrust or Weights & Biases provide cloud-based dashboards and evaluations, and the OpenAI Agents SDK offers tracing for its own ecosystem, AccordKit sits at the intersection, an AI-agnostic, local-first instrumentation layer for everyone else.
AccordKit focuses on openness and developer autonomy, capturing the same observability data others need SaaS for, but right inside your dev environment.
| Axis | Meaning |
|---|---|
| X-axis → | Openness / Vendor-Agnosticism, how portable and independent the tool is |
| Y-axis ↑ | Developer SDK Focus — whether it’s built for local development or as a managed platform |
🟩 AccordKit lives at the top-right corner, open, extensible, SDK-first.
From local JSONL logs to cloud integrations, it gives developers complete ownership of their traces.
