OpenBook vs Gumloop
Gumloop is a polished, closed-source SaaS for building AI automations on a visual canvas, popular for fast no-code AI workflows. OpenBook offers a comparable visual builder plus a deeper agentic runtime — agents with long-term memory, an AI builder, and human-in-the-loop — but open source and self-hostable, with no per-credit metering and full data ownership.

Why teams pick OpenBook over Gumloop
Open source & self-hosted
Run OpenBook on your infrastructure and read every line. Gumloop is a closed SaaS that runs in their cloud.
Agents with memory
OpenBook agents run a plan-act-observe loop and remember across runs by default. Gumloop centers on AI automation steps on a canvas.
No credit metering
No per-run credit pricing — pay your model provider directly. Predictable at any volume.
AI builder + human-in-the-loop
Describe a workflow and OpenBook wires the graph, with real pause-for-approval and resume from an inbox.
MIT, self-host, your keys.
Closed SaaS with credit-based pricing.
When to choose which
- You need to self-host for privacy, compliance, or cost control
- You want agents with memory and a real workflow engine, not just AI automation steps
- You want to avoid per-credit metering and own your data
- You want a fully managed SaaS with a fast no-code AI automation canvas and zero ops
- You prefer prebuilt AI nodes over assembling actions and plugins
Recreate each Gumloop flow as an OpenBook workflow: AI steps become agents, automation steps become actions or http.request calls, and the AI builder can scaffold the graph.
