The debugging agent that connects your coding agent to production
Combines frontend screens, backend traces and logs, and request/response headers into a single correlated view of what went wrong.
Avoids the random sampling that leaves holes in observability data, so the specific request that triggered a bug is still available.
Routes issues to Claude Code, Codex, Copilot or whichever agent your team already uses, with no need to adopt a proprietary alternative.
Runs alongside your agent, caches sessions locally and sends only the data for identified issues - and never requires access to your code.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
