Gumloop is the most feature-overlapping tool in this comparison — a real flow canvas, agent nodes, MCP support, model choice across providers, and genuinely good human-in-the-loop. If you're evaluating the category seriously, it's probably on the list.
The gap is what happens during the run. The canvas is where you build, not where you steer — and Gumloop's documented answer to a stuck run is to restart the flow.
| Dimension | Gumloop | LiveGraph |
|---|---|---|
| Canvas during a run | Inert at run time — you build on it; you don't steer on it. | Stays live — every hop is visible while it executes, and dragging an edge changes where this run goes next. |
| Stuck-run recovery | Restart the flow — the documented answer to a run gone wrong. | Drag an edge or edit the prompt; the run continues from the new route. |
| Human-in-the-loop | Real approval gates — pause → approve/reject → resume at pre-wired points. | Run-level gates that park at the approvals queue, plus per-tool-call gates (e.g. a single http_request endpoint) — the pending payload is always visible to the approver. |
| Model roster | Model-agnostic across the major providers. | Per-node provider and model — Anthropic, OpenAI, Google, Groq, OpenRouter, or an OpenAI-compatible endpoint; your call per node. |
| Hosting | Hosted; self-host/VPC is an Enterprise-tier option. | Hosted web app at livegraph.ai. |
| Run audit trail | Not evaluated | Every hop lands as an ordered run event — input, output, the routing explanation, and its cost — and approval decisions are stamped with who and when. |
| Pricing | Credit-metered — users report burns like tens of thousands of credits in a single runaway flow. | Flat team price — runs are never metered. Model usage on hosted keys is metered on top; your own keys are never marked up. |
Competitor rows are limited to claims verified in our own research — "Not evaluated" means we didn't check, not that the capability is missing. On the LiveGraph side, one nuance: runs started from chat or the canvas Run button are steerable; unattended runs (API, schedules, webhooks) run pinned to the graph they started on — steering is a watched-run feature, by design.
Of the closed builders, Gumloop is the one we'd benchmark ourselves against — which is exactly why the run-time difference matters. A canvas that freezes when the run starts is a drawing of your system. Ours is the system.
The live demo runs a real multi-agent graph in your browser — no signup, no API key — including the mid-run edge drag. If the canvas earns it, an account takes a minute.
