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.

Open-source database of AI models, prices and capabilities
Every model uses a consistent provider/model format so the same model across providers can be compared directly.
Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
Input and output prices per million tokens listed alongside release and update dates.
Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
Offers an expansive infinite canvas for team brainstorming and visual workshops, but lacks Eraser's code-to-diagram automation.
#1
SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#2Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.

SpecialistIncludes model pricing trackers and developer news alongside tools directories, but less focused on raw API specs.
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.

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


Stronger focus on standard Mermaid syntax and code-driven diagrams, but lacks Eraser's native autonomous architecture doc generation.

SpecialistCatalogues and compares AI infrastructure tools and services across categories, but lacks deep per-token pricing tables.

SpecialistAI code documentation for any codebase, kept current automatically

SpecialistExcellent for turning cloud architecture directly into infrastructure-as-code, but narrower focus compared to general technical documentation.
SpecialistDescribe your system in words, get a diagram you can edit
Great for interactive chat-based diagram editing from URLs and text, but less specialized for deep engineering infrastructure docs.
