One compact desktop client for APIs, sockets, and raw network traffic. Built for developers who need more than just HTTP.
Compose query parameters, toggle headers, send raw JSON, URL-encoded forms, or multipart payloads, then inspect response bodies, headers, timing, and trace.
Discover services through reflection or load proto and protoset files when the server does not expose its schema.
Keep stateful connections attached to request tabs and follow incoming, outgoing, system, and error frames in one timeline.
Choose exactly how a response ends: idle timeout, connection close, exact byte count, delimiter, or length prefix.
Send text, editable hexadecimal data, or imported binary files without accidental encoding changes.
Keep related requests together in nested folders, move them with forgiving drag-and-drop zones, and save changes directly back to the source collection.
Group HTTP, gRPC, WebSocket, TCP, and UDP requests inside folders.
Open saved requests in tabs and update existing collection items with Ctrl+S.
See collection ownership and active WS/WSS requests without opening every item.
Return to previous executions without replacing the request tabs you are actively editing. Each history item preserves the context needed to inspect what happened.
Review HTTP, gRPC, WebSocket, TCP, and UDP executions in one place.
Return to payloads, status, timings, headers, and response data.
Delete individual entries or clear the complete history when it is no longer useful.
Browser-based tools force socket buffers through text encodings, corrupting non-printable bytes. OmniPort preserves raw data streams exactly. Hover over any byte in the Hex column to instantly locate its ASCII representation.
Hovering maps values to printable characters on the fly.
Read by delimiter, byte size, length prefix, or idle times.
Load binaries or hex payloads to send directly down the wire.
Ditch browser sandboxes and debug multi-protocol network streams losslessly. Available on all desktop platforms.
