Why it exists
When you are wiring up a new LLM provider, the first failure mode is usually boring: wrong key format, wrong project scope, exhausted quota, or a region mismatch.
PulseKey turns that first-mile debugging step into a dedicated surface instead of making you decipher provider dashboards and raw API errors.
What makes it interesting
The interaction model is intentionally more playful than most dev tools. Provider selection happens on a draggable ring instead of a standard dropdown, which makes the product feel like a tiny standalone utility rather than a generic form.
- —Runs a real test request against OpenAI, Anthropic, Gemini, or OpenRouter
- —Normalizes provider-specific failures into clearer user-facing states
- —Keeps the API key ephemeral and avoids persistence on the server
Integration note
This version is ported into the portfolio itself as a native embedded demo, so it behaves like a real product surface inside the site rather than a screenshot or offsite link.
