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.
AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.

#1
SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#2Free / Open-sourceGuideline-directed medical answers with citations, built for clinicians
Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.

Free / Open-sourceAI-powered UI design and prototyping for product teams
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.
Measure, predict and prevent heart disease with data

Free / Open-sourceOpen-source tool specifically tailored for database schema visualization and ER diagrams, but lacks general system documentation features.


Free / Open-sourcePhysics-driven AI that automates PCB placement and routing

Stronger focus on standard Mermaid syntax and code-driven diagrams, but lacks Eraser's native autonomous architecture doc generation.
Free / Open-sourceReady-made database schemas, sample data and an AI schema designer

SpecialistAI code documentation for any codebase, kept current automatically
