Trace AI requests, workflows, and costs in one timeline
PromptLayer is AI observability for developers. Trace requests, workflows, token usage, latency, costs, and failures through a single timeline and waterfall view. Follow complete execution paths across multi-step AI systems, understand where failures occur, identify slow or expensive workflow steps, and debug AI applications with the same visibility developers expect from modern software systems.
Hey everyone 👋
I'm Sam, a developer who spends a lot of time building AI-powered applications.
As workflows became more complex, I found myself constantly asking questions like:
* Which model call failed?
* Why did this workflow suddenly get slower?
* Where did these tokens go?
* Which step generated this response?
Most AI tooling focused on prompts or playgrounds. I wanted something closer to how developers debug software: requests, traces, timelines, waterfalls, costs, and failures.
So I built PromptLayer.
PromptLayer lets you instrument AI workflows and visualize the entire execution path, from individual model calls up to full workflow traces.
Current free beta includes:
* Request explorer
* Workflow tracing
* Waterfall views
* Token and latency tracking
* Model analytics
* JavaScript SDK
* Free beta access
I'd genuinely love feedback from anyone building with OpenAI, Anthropic, or multi-step AI workflows.
Thanks for checking it out.
