AgentCanvas
Built at Google I/O Hackathon · May 23, 2026 · San Francisco, CA
AgentCanvas is the first visual orchestration canvas for Gemini 3.5 Flash sub-agent pipelines. Most multi-agent systems today are black boxes - you run code, agents execute, you see a final output with no visibility into what happened in between. AgentCanvas changes that. Drag and drop Gemini agents onto a canvas, connect them into pipelines, define their roles and tools, and watch every tool call execute in real time with a live animated trace. Every agent handoff, every tool call, every output is visible as it happens. Built entirely during the hackathon. Three demo pipelines included: Research (Scout → Analyst → Writer), Productivity (Planner → Scheduler → Communicator), and Engineering (Researcher → Engineer → Reviewer). Fully customizable add agents, define roles, draw connections, run any pipeline. Tech stack: React frontend with live SSE streaming, FastAPI backend, Gemini 3.5 Flash for all agent execution.
