A workbench for sending prompts to agent endpoints and inspecting their live tool calls, tokens, subagents, timelines, and replays.

Why it surfaced

Langport reconstructs delegated-agent runs as a visible tree instead of flattening them into an opaque tool call. It supports streamed SSE or NDJSON endpoints with no SDK or instrumentation, then lets you inspect, replay, compare, and share the run.
