Compose multi-step AI workflows, without the boilerplate
Build, run and debug agentic workflows on a visual graph — backed by production-ready orchestration under the hood.
Serious orchestration with whiteboard ergonomics
All the primitives you'd want in a production agent stack — without the weekend lost to glue code.
Visual graph builder
Drag reusable nodes onto the canvas — RAG, search, chat, tools — and connect them with typed edges.
Human-in-the-loop
Pause for approvals, edits and overrides mid-run, without losing state.
Run history & debugging
Every run is saved, replayable and inspectable step-by-step.
Everything you need to ship an agent to production
Flows is the layer between 'I have an idea' and 'it's running reliably in production.'
Visual graph builder
Draw the workflow, ship the automation
Onsomble Flows is built on a production LangGraph engine, but you never have to touch its internals. Sketch your agent on a canvas and it just runs.
- Drag-and-drop canvas with typed connectors
- Live preview of every node's input and output
- Version and fork any flow instantly

Reusable nodes
Every agent primitive you need, built in
A growing library of first-class nodes covers retrieval, chat, tool calls and classification — plus escape hatches for anything custom.
- RAG retrieval over your sources
- Web search, chat and classifier nodes
- Custom Python and HTTP nodes

Human-in-the-loop
Keep humans in control where it counts
Add approval checkpoints to any step. Reviewers can accept, reject or edit mid-run, and the flow picks up exactly where it paused.
- Pause for review and approval
- Edit intermediate outputs mid-run
- Resume with one click from any checkpoint

Run history & debugging
See exactly what happened, every time
Every run is saved with full state, cost and latency traces — so you can replay, fork and debug any execution long after the fact.
- Every run saved with full state
- Per-step cost, latency and token usage
- Replay and fork any prior run

From idea to running automation in minutes
No scaffolding. No YAML. No rebuilding your infra every time you iterate.
Draft
Drag nodes onto the canvas and connect them to describe your flow end to end.
Run
Test the flow on real inputs with live tracing, step-by-step state and per-node cost.
Ship
Publish the flow as an API, schedule it, or embed it in your app with one click.
Onsomble Flows vs. rolling your own
What building an agent pipeline looks like with Onsomble — and without.

Python + LangChain glue
“Flows replaced a mess of Python scripts and LangChain boilerplate with a graph our whole team can read. The human approval step alone was worth the switch.”
