Build, deploy, and govern production-ready agentic AI workflows
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.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.

#1Offers a streamlined no-code builder for deploying custom AI agents, but lacks Dify's open-source flexibility.

Free / Open-sourceA self-hosted chat interface for running local LLMs, though lighter on complex visual workflow orchestration.
#3
Free / Open-sourceReal-time vision AI models and a full platform to train, annotate, and deploy them


The environments frontier AI trains on, and the agents that do the recurring work

Human-validated training data and evaluation services for frontier AI models


SpecialistProvides advanced programmatic frameworks for document parsing and RAG pipelines, but requires coding instead of visual canvases.


AI data infrastructure for building production-grade models
Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.
The multimodal data layer for computer vision and physical AI teams

Built for scaling multi-agent workforces and B2B task automation, though less focused on open-source RAG pipelines.

Focuses on visual drag-and-drop orchestration for building chatbots and autonomous agents without writing code.
