Engineer better proteins, faster, with AI
Start from a target or your own sequence and have Cradle design an optimized plate of candidates informed by your data and domain knowledge.
Improve efficacy, developability, and manufacturability in parallel rather than one property at a time, compressing time to a target profile.
Every round incorporates results from the previous one, so experimental data compounds across campaigns and prior failed programs stay useful.
Everything in the web application is exposed through the API, so computational teams can script campaigns and wire Cradle into existing pipelines.

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.

#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.
#3Free / Open-sourceGuideline-directed medical answers with citations, built for clinicians

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


Free / Open-sourceAI-powered UI design and prototyping for product teams
Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.

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.

Provides an all-in-one visual workspace for building custom AI agents and publishing them to messaging platforms.
