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.

An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.

#1
SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#2Faster for ad hoc statistical analysis and data visualization from natural language, but lacks Hex's robust notebook workflows.
Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.

SpecialistOffers a spreadsheet-based interface with live data and Python execution, but lacks Hex's structured data app builder.

Simpler plain-English querying and dashboard generation for databases, but lacks Hex's advanced polyglot notebook environment.

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.
SpecialistSpecializes in embedded white-label customer dashboards, but less suited for internal data team ad hoc analysis than Hex.

Focuses heavily on governed semantic layers and audited SQL generation, but lacks Hex's interactive data app builder.

Stronger automated business reporting and governed chat analysis, but less flexible for custom Python coding than Hex.
