## Eraser

Eraser is a technical design platform aimed at the people who document architecture: enterprise architects, DevOps and platform engineers, consultants, and software teams. The core promise is speed without sloppiness, so instead of dragging boxes for hours you describe the system or point Eraser at a source of truth such as code, a cloud account, a CMDB, or a spreadsheet, and it produces a diagram that already follows sensible layout rules.

Beyond static images, Eraser supports interactive maps that zoom from a company-wide view down into a single service, guided explainers that walk teammates through a system, and AI documents for design docs and technical documentation. Team governance features such as shared style presets, naming rules, and reference architectures keep output consistent as more people create diagrams. An open-source agent toolkit and MCP server let tools like Claude, Cursor, and ChatGPT create, search, and export diagrams programmatically.

Prices are organized in tiers that include a free entry point, paid plans, and enterprise agreements, with multi-tenant, single-tenant, and self-hosted deployment options for larger organizations. Security posture includes SOC 2 Type 2 certification and SAML SSO.

**Pricing & Plans:** Freemium with paid plans and custom enterprise pricing. A free tier and free tools such as DiagramGPT are available, while paid individual and team plans plus enterprise agreements cover advanced governance, security, and deployment options; check the pricing page for current rates.

- **AI diagram generation:** 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.
- **Maps from live systems:** 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.
- **Diagram-as-code integrations:** Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
- **Open-source agent toolkit and MCP server:** 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.
- **Team style governance:** Apply presets, naming and notation rules, and reference architectures so every teammate's diagram ships on-brand and consistent.

**Strengths:** Turns prompts, code, and files into properly laid-out diagrams instead of raw box-and-arrow output; Interactive maps and explainers make complex systems understandable to non-architects; MCP server and open-source toolkit fit agent-driven and self-hosted workflows; Enterprise controls such as SSO, SAML, and SOC 2 Type 2 certification

**Limitations:** Heaviest value comes with team and governance features that need setup; Advanced mapping and self-hosted deployment are aimed at larger organizations rather than solo users

## Orca-Tool

Docker Compose files are powerful but unforgiving: indentation, service names, volumes, and dependency links all have to line up, and a long file quickly becomes hard to reason about. Orca takes the opposite approach and presents the same configuration as a visual map of containers and their connections, which is much easier to review and discuss with someone who does not read YAML fluently.

The tool ships with starting points for the stack patterns most teams build first. You can begin from a blank diagram or from a template such as WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, or a full Elasticsearch stack including Kibana, Logstash, and APM. From there you adjust services, add containers, and reorganise the layout while the file structure follows what you draw.

Because it runs in the browser and works on plain Compose definitions, Orca fits well as a planning and teaching aid: it is a quick way to draft a new environment, to explain an existing one during onboarding, or to sanity-check a stack before committing it to a repository. It is positioned as a free tool with no account requirement implied by the product itself.

**Pricing & Plans:** Orca-Tool is listed as a free tool. No paid tier or pricing page is published on the site, so there is no cost information to quote beyond its free availability.

- **Visual Compose editor:** Represent services and their relationships as a diagram so the shape of a multi-container stack is readable without parsing YAML line by line.
- **Ready-made stack templates:** Start from predefined setups including WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, and an Elasticsearch stack with Kibana, Logstash, and APM.
- **Blank canvas for custom stacks:** Begin with an empty diagram when your architecture does not match any template and assemble the services yourself.
- **Graphical container orchestration overview:** See how containers, databases, and supporting components fit together before you run them, which helps catch missing links early.
- **Browser-based, no install:** Work directly on the web app, which makes it convenient for quick drafts, demos, and explaining setups to teammates.

**Strengths:** Makes multi-container architecture legible to people who do not read YAML fluently; Includes templates for the most common self-hosted and app stacks; Runs in the browser with nothing to install; Free to use, with no pricing page suggesting a paywall for core editing

**Limitations:** Well suited to planning and documentation rather than heavy production orchestration management; Diagrams can become crowded once a stack grows to many services; Limited published documentation, so some behaviour has to be discovered by trying it
