Key strengths
- Zero-Code Instrumentation: One URL change instruments every LLM call — no SDK, no decorators, no code changes beyond the base URL.
- Immediate Cost Visibility: Real-time cost dashboard shows exactly how much each user, feature, or prompt variation is spending — before the cloud bill arrives.
- LLM Cost Reduction: Built-in prompt caching reduces API calls for repeated inputs, turning the observability layer into a cost-savings tool.
Best fit
- Indie AI developers and small teams who want instant LLM observability without instrumenting code
- SaaS companies building per-user AI features who need user-level cost tracking and rate limiting
- Teams looking to reduce OpenAI bills by adding prompt caching with minimal integration effort
