It works on JDK 8+ and does not force a Spring dependency, so it can slot into existing enterprise Java stacks cleanly. The entry point is a unified chat model API: configure a provider such as OpenAI with an API key and model name, then call chat() to get a response. Beyond basic model calls, Agents-Flex is designed as a composable toolkit. You layer in knowledge retrieval (RAG), tools and function calling, multimodality, OCR, and a Skills system where reusable, versionable capability packages combine a SKILL.md description with scripts and assets. A SkillRuntime exposes consistent command, file and search interfaces across local or remote execution targets, so long-running tasks like OCR and video generation can be submitted async and polled by status. The framework emphasizes architectural clarity and production readiness. Its AgentRunner orchestrates policy and middleware, while a Turn Store persists snapshots and events for long-task recovery. Streaming responses, synchronous image generation and asynchronous task handling are all first-class, and observability hooks help teams operate these systems in production rather than just prototype them. **Pricing & Plans:** Agents-Flex is free and open source under the Apache 2.0 license. There is no commercial license fee for the framework itself; costs come only from the LLM or cloud providers you connect. - **Unified chat model API:** Configure any supported provider with an API key and model name, then call chat() for a consistent interface across models. - **Agent orchestration:** AgentRunner combines policy and middleware to coordinate models, tools and sandboxes inside a single execution flow. - **Skills packages:** Reusable, versionable capability definitions that bundle a SKILL.md, scripts and assets, discovered from local directories or remote storage. - **RAG, multimodality & OCR:** Add knowledge retrieval, image generation and OCR pipelines on demand, mixing synchronous and asynchronous execution styles. - **Production runtime:** A Turn Store persists snapshots and events so long-running tasks can recover, supported by streaming responses and observability. **Strengths:** Apache 2.0 open source with a permissive license for commercial use; Java-native design that fits existing JVM and enterprise stacks; Composable architecture covering RAG, tools, Skills and OCR in one framework; Async task handling and a Turn Store for reliable long-running workloads **Limitations:** Documentation and community content skew toward Chinese, which may slow English-only teams; As a younger framework, the surrounding ecosystem is smaller than more established Python options; Requires Java expertise, so it is not aimed at non-developers [Profile (Markdown)](https://openaitools.app/tool/agents-flex.md) ## Dify Dify pairs a visual canvas with code-level control so both technical and non-technical teams can assemble AI applications and agents. Workflow Studio turns prompt logic into an inspectable execution graph of building blocks: retrieval, branching, tool calls, human-in-the-loop steps, and model calls. Agent builder lets you create agents by chatting or by configuring them directly, then run them as a standalone app, embed them into a website, or reuse them as a node inside a larger workflow. A major part of the platform is context engineering. The Knowledge Pipeline lets you define repeatable ingestion flows for files, websites, online documents, and cloud drives, handling extraction, cleaning, chunking, indexing, and retrieval testing before a knowledge base is attached to agents or workflows. The Marketplace supplies model providers, tools, data sources, and MCP integrations that teams can install once and then reuse across many apps as approved plugins. Dify ships in three deployment shapes: Dify Cloud (fully managed SaaS with workspace, logs, and scaling handled for you), Dify Enterprise (self-hosted or VPC deployment with SSO/SAML, RBAC, audit logs, Helm charts for Kubernetes, and enterprise support), and the open-source Community Edition, a source-available single-command Docker deployment with a large GitHub community. Published apps can be delivered as hosted web apps, API endpoints, embeds, or MCP-compatible tools, with logs, feedback, annotations, latency, and usage analytics to keep improving them after launch. **Pricing & Plans:** Freemium model with a free cloud sandbox and free trial credits, paid Cloud plans that scale with team size, storage, logs, and usage, and a free open-source Community Edition. Dify Enterprise is quoted per deployment via sales. - **Workflow Studio:** A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off. - **Agent Builder:** Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows. - **Knowledge Pipeline:** Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live. - **Plugin Marketplace and MCP:** Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace. - **Flexible Deployment and Observability:** Run on managed Cloud, in your VPC, or self-hosted with Docker, and monitor published apps through logs, annotations, feedback, latency, and usage data. **Strengths:** Combines a visual builder with code-level extensibility in one product; Three deployment options, including a free self-hosted Community Edition; Strong retrieval and knowledge pipeline tooling for RAG applications; Large plugin marketplace plus MCP support reduces integration work **Limitations:** Self-hosted deployments require real infrastructure and maintenance effort; Complex multi-step workflows take time to learn and tune; Advanced enterprise governance features sit behind a sales-quoted plan [Profile (Markdown)](https://openaitools.app/tool/dify-ai.md) ## Frequently Asked Questions ### How do Agents-Flex and Dify compare in monthly traffic?
