Render and debug SIP traces, in your browser.
Drop a PCAP, PCAPNG, or sngrep log. SIP Flow renders the call ladder and calls out RFC issues — all in your browser. AI-assisted debugging is coming soon.
No signup. Parsing happens entirely in your browser.
Everything you actually do in sngrep, but in a tab.
Universal SIP parser
PCAP, PCAPNG, sngrep text logs, raw SIP captures. Auto-detected, no flags.
Live Homer feed
Stream live calls from your Homer 10 / qryn instance. Search history by Call-ID or phone number, then export to PCAP or text.
Call-flow ladder
Sequence diagram per Call-ID with retransmissions, deltas, and message inspector — all rendered locally.
RFC-grade issue detector
Missing 200 OK / ACK, codec mismatch (488), one-way audio from SDP, NAT mismatches, auth loops.
- Coming soon
Debug with AI
Ask Gemini to diagnose. Pseudonymized client-side; trace minimized while preserving every SDP body.
- Coming soon
Vendor-aware RAG
Retrieval grounded in Asterisk, FreeSWITCH, Kamailio, OpenSIPS, and the relevant RFC sections.
Private by default
Pseudonym mapping never leaves your browser. Raw PCAP upload is off by default and explicit.
Your call data does not have to leave your browser.
The SIP renderer is 100% client-side — no upload, no signup, no metering. Your PCAPs and SIP logs never leave your browser. When the optional AI debug flow lands, it will pseudonymize phone numbers, IPs, and Call-IDs locally before any data is sent.
- Parsing, ladder rendering, and issue detection run entirely in your browser.
- No account, no upload, no metering for the renderer.
Got a tricky trace? Try it now.
The renderer is free, unlimited, and runs entirely in your browser. AI debugging is coming soon.
