Parse, debug, and reconstruct Server-Sent Events (SSE) streams locally. Inspect raw events, filter by event type, and assemble streamed text from OpenAI, Anthropic, Gemini, and generic SSE responses.
Drop SSE stream file here
Parsed events will appear here
Paste or drop your raw SSE stream output to instantly parse, inspect, and reconstruct AI-generated text responses.
Copy raw SSE output from your terminal or browser DevTools Network tab and paste it into the left panel.
The parser splits frames by double newlines, detects the AI provider, and extracts each data payload automatically.
View the fully reconstructed text in the 'Final Text' tab, or inspect raw JSON payloads in 'Detailed Log'.
A: Yes, completely free and runs 100% in your browser.
A: All processing happens locally. No data is ever sent to any server.
A: OpenAI, Anthropic, and Google Gemini streams are auto-detected.
A: No — browser CORS restrictions prevent live fetching. Run curl in your terminal and paste the raw output here instead.
Debugging AI streaming APIs means wading through hundreds of raw SSE frames. This tool gives you instant visibility without writing a single script.
Privacy First
Your API payloads never leave your browser. Everything is processed locally.
Auto Provider Detection
Automatically detects OpenAI, Anthropic, and Gemini stream formats and extracts text without configuration.
Full Reconstruction
Assembles all streamed tokens into the complete response text — exactly what the end-user would have received.
