The DevTools for
AI Streaming Infrastructure
Inspect, benchmark, and compare any SSE endpoint — free, no account needed. Ship production AI with the hosted gateway.
Works with every provider
Everything you need to ship AI streaming right
Six purpose-built tools, one unified workspace.
Paste any endpoint, fire a request, see live SSE frames, timing bars, and RAIS compliance in real time. Session history included.
Run two endpoints simultaneously. Side-by-side TTFB, tok/s, token count, and compliance — with delta percentages.
Run N rounds across Groq, OpenAI, Anthropic, Ollama, and local servers. See P50 latency, throughput, and cost estimates.
Record any stream, then replay it at original speed, step-by-step, or at 10× — a debugger for SSE timing and event order.
Choose platform + provider, get a complete scaffolded project. Next.js, Vite, Express, FastAPI, HTML — any stack.
Run the full RAIS v1 suite: type fields, text/done/error events, event ordering, JSON validity, unknown frame detection.
Zero setup. Test in seconds.
Local server, hosted API, Groq, OpenAI, Anthropic — anything that streams.
Requests proxy through the studio server, eliminating CORS entirely.
See every raw frame, check compliance, benchmark against competitors, generate starter code.
