The State of AI Agent Frameworks in 2025 - DevNavigator

2 min read Original article ↗

As companies race to operationalize AI, one question keeps coming up: Which agent frameworks are actually being adopted in production? Recent survey data shows a clear consolidation around a few dominant players, with OpenAI and Google leading the pack, while frameworks like LangChain, LangGraph, and CrewAI continue carving out important, but more specialized, niches. The results reveal a rapidly maturing ecosystem where organizations are prioritizing stability, orchestration reliability, and integration depth over experimentation. Below is a breakdown of each framework’s role, strengths, and tradeoffs.


OpenAI Agents SDK (51%)

Summary: A first-party, production-ready framework tightly integrated with OpenAI models, tools, and memory.
Pros: Deep integration with OpenAI’s platform; strongest reliability and tooling support; easy to scale into production.
Cons: Less flexible for multi-model or hybrid-cloud deployments; ecosystem is still evolving quickly.


Google Agent Development Kit (ADK) (40%)

Summary: Google’s modular agent toolkit designed to build flexible, cross-platform workflows powered by Gemini.
Pros: Highly extensible; strong cross-service interoperability; great for Google Cloud environments.
Cons: Best functionality is tied to Google’s models; adoption is still catching up to OpenAI’s momentum.


LangChain (24%)

Summary: A popular open-source framework for chaining LLM calls, retrieval steps, and tools into custom workflows.
Pros: Massive ecosystem; excellent flexibility; strong for rapid prototyping and experimentation.
Cons: Can become overly complex; orchestration reliability lags behind newer agent frameworks.


LangGraph (16%)

Summary: A stateful, graph-based orchestration engine that enables deterministic, multi-step and multi-agent systems.
Pros: Robust state management; ideal for complex, branching workflows; more production-oriented than LangChain alone.
Cons: Requires deeper engineering expertise; still evolving with frequent updates.


CrewAI (15%)

Summary: A multi-agent collaboration framework where agents with defined roles coordinate as a “crew” to solve tasks.
Pros: Easy to set up multi-agent teamwork; widely used for structured task automation.
Cons: Not optimized for enterprise-scale reliability; limited controls for long-running orchestration.


PydanticAI (10%)

Summary: A structured-output-driven framework that uses Pydantic schemas to ensure validated, type-safe LLM responses.
Pros: Guarantees clean, structured outputs; great for data workflows where correctness is critical.
Cons: Not a full agent system; best used as a complement to other orchestration frameworks.


Temporal (7%)

Summary: A durable workflow engine used to provide reliability, retries, state, and long-running orchestration for agent systems.
Pros: Industry-leading workflow durability; perfect for enterprise automation and failure-resistant AI pipelines.
Cons: Not an agent framework itself; adds operational overhead and requires dedicated expertise.
