LangGraph Studio
Visual IDE for building, debugging, and inspecting LangGraph agent workflows

LangGraph Studio is a specialized development environment designed for engineers building agentic applications on top of the LangGraph framework. It provides a visual interface for inspecting graph structure, tracing execution paths, and understanding how agents move between nodes, tools, and states. Beyond visualization, the studio offers interactive debugging features such as state editing, replay from intermediate steps, and live interaction with running agents. This makes it easier to diagnose loops, tool-call failures, and unexpected branching behavior that often appear in multi-step LLM workflows. It integrates with LangSmith for tracing and observability, giving teams a unified way to develop, test, and iterate on complex agent systems before deploying them to production.

LangSmith
Observability, evaluation, and debugging platform for LLM applications from the LangChain team

LangSmith is a developer platform built by the team behind LangChain to help teams trace, test, evaluate, and monitor applications powered by large language models. While it integrates tightly with the LangChain and LangGraph frameworks, it is framework-agnostic and can instrument any LLM application through its SDKs and APIs. Its core purpose is to address the inherent unpredictability of LLM-based systems, where outputs are non-deterministic and failures can be subtle, by giving developers visibility into what their chains, agents, and prompts are actually doing at runtime. The platform centers on tracing: each run of an application produces a detailed, nested trace showing every step, including prompts sent, model responses, token usage, latency, tool calls, and intermediate outputs. This makes it easier to debug complex multi-step agents and retrieval-augmented generation pipelines where the source of a bad answer might be buried several layers deep. Developers can inspect individual traces, filter and search across runs, and drill into the exact inputs and outputs at each node. LangSmith also provides evaluation tooling for measuring application quality. Teams can build datasets from production traces or curated examples, run their application against those datasets, and score outputs using built-in evaluators, custom code-based checks, or LLM-as-judge approaches. This supports regression testing when prompts or models change and helps quantify whether changes actually improve results rather than relying on intuition. For production use, it offers monitoring dashboards that track metrics such as latency, cost, error rates, and feedback over time, along with the ability to collect human feedback and user annotations. A prompt management and playground component lets teams iterate on and version prompts, and compare model outputs side by side. LangSmith is aimed primarily at developers and teams shipping LLM features who need to move beyond ad hoc print-statement debugging toward systematic observability and evaluation. Its main strength is the depth of integration with the LangChain ecosystem and the unified workflow connecting tracing, datasets, and evaluation. Honest trade-offs include that the richest experience assumes you are comfortable in the LangChain/LangGraph world, that LLM-based evaluation is itself imperfect and requires careful design, and that it is a hosted commercial product with usage-based pricing, though self-hosting options exist for some plans. It competes with other LLM observability tools such as Langfuse, Helicone, Arize Phoenix, and Weights & Biases Weave.

- Dataset creation and automated evaluation
- Built-in, code-based, and LLM-as-judge evaluators
- Production monitoring dashboards

- Prompt management, versioning, and playground


Zep AI Memory is a developer-focused memory service that gives AI agents persistent, structured recall across conversations and sessions. It captures chat history, extracts key facts, and organizes them into a knowledge graph so agents can retrieve relevant context on demand instead of stuffing entire histories into prompts. The platform handles summarization, entity extraction, and semantic search behind a simple API, letting teams add stateful memory to chatbots, copilots, and autonomous agents without building custom retrieval infrastructure. It is designed to scale with production workloads while keeping prompt sizes and token costs predictable. Zep integrates with common LLM frameworks like LangChain and LlamaIndex and provides SDKs for popular languages, making it straightforward to drop into existing agent stacks.
- Long-term conversational memory
- Automatic fact and entity extraction
- Knowledge graph storage
- Semantic and hybrid search
