Comparison
LLMWeave vs LangGraph
A low-level engine for stateful agent graphs, versus managed durable workflows.
Short answer
LangGraph is a low-level orchestration engine for stateful, long-running agent graphs that you assemble and operate. LLMWeave runs durable multi-model workflows for you, with the state, retries, and concurrency handled. The choice is still build-and-operate versus run-the-workflow, but the stateful runtime makes the gap clearer.
Both do durable, stateful execution. One you operate
LangGraph is built for exactly the hard case: long-running, stateful agent workflows with branching and loops. But you still own deploy, state persistence, retries, and concurrency. The graph is yours to build and run.
LLMWeave gives you durable checkpointed execution as a managed service. Steps are persisted automatically, human-review pauses are first-class, and per-plan concurrency is enforced for you. You define what the weave does, not how to keep it alive.
A builder, still a builder
LangGraph is framework-flavored: you bring the graph design and the operational knowledge. LLMWeave is the finished managed product with multi-model orchestration and billing-grade execution already wired in.
Side by side
| LLMWeave | LangGraph | |
|---|---|---|
| What it is | Managed durable-workflow product | Low-level orchestration engine |
| Stateful execution | Built in, checkpointed for you | Built in, you operate it |
| Who deploys + scales | LLMWeave | You |
| Multi-model | Fan-out + synthesis as primitives | You wire model nodes |
| Human-in-the-loop | First-class review pauses | You build the interrupt + resume |
| Best fit | Run sophisticated workflows fast | Own a bespoke agent runtime |
When LangGraph is the right call
We are not trying to be LangGraph. Choose it when:
- You need a bespoke agent runtime with custom graph topology you control completely.
- Your team has the engineering capacity to operate stateful infrastructure long term.
- The orchestration logic is unusual enough that no managed product models it.
Common questions
Does LLMWeave do stateful, long-running workflows like LangGraph?
Yes. LLMWeave runs durable, checkpointed multi-step workflows with human-review pauses and automatic state persistence. The difference is that LLMWeave operates that infrastructure for you instead of handing you an engine to run yourself.
Can LLMWeave handle human-in-the-loop steps?
Yes. Human review is a first-class pause: a workflow can wait for input, then resume from where it left off, without you building the interrupt-and-resume plumbing.
