## 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

## Outerbase

Outerbase started as a modern, browser-based alternative to heavyweight database GUI clients, and has since grown into a collaborative data workspace. The core idea is that the people who need answers from a database — analysts, researchers, support engineers — should not have to wait on SQL expertise or on a dedicated analytics team. Outerbase connects to a broad set of SQL and NoSQL engines, then layers AI on top: an "Ask EZQL" natural-language box, an AI query editor that spots and fixes mistakes, and automatic chart generation from query results.

The everyday working surface is the table view. It is a from-scratch grid that behaves closer to a spreadsheet than to a classic database client, with an expanding set of table plugins, inline editing, and embeddable components from the company's open-source Astra library so the same table can be dropped into your own product. Dashboards push the same idea further: teams assemble self-serve analytics boards, ask the assistant to build charts, and embed the results anywhere through open-source web components.

The Data Catalog is what makes the platform collaborative rather than personal. Teams define business terms so humans and the AI interpret columns consistently, draw relational diagrams, and create virtual relationships between columns without touching the underlying schema. Security is handled at the connection level with two-factor authentication, database role and permission scoping, breach checks, SSH tunneling, AES/RSA encryption and private AI models that are not trained on customer data; the company advertises SOC 2 Type 2 and HIPAA compliance. In 2025 Outerbase announced that it had joined Cloudflare, and the website now directs interested teams to get in touch for commercial details.

**Pricing & Plans:** Outerbase does not publish self-serve tiers on its site; enterprise and team access is handled through a contact-sales conversation. The product is open-source friendly — much of the interface layer, including the table and chart components, is available on GitHub — and you can evaluate it there before talking to the team. Ask for a quote based on the number of connections, seats and compliance needs.

- **Ask EZQL natural-language queries:** Type a question in plain English and get an instant answer drawn from your connected data, without writing SQL by hand.
- **AI query editor and auto charts:** The AI editor reviews your SQL, corrects mistakes and suggests improvements, then turns result sets into presentation-ready charts automatically.
- **Spreadsheet-style table editor:** A snappy grid built from scratch for fast navigation of large tables, with customizable table plugins and edit-in-place controls.
- **Self-serve dashboards:** Compose analytics boards manually or hand them to the AI, then embed charts anywhere using open-source web components.
- **Data Catalog with business terms:** Document shared definitions, generate relational diagrams and add virtual relationships so teams and the AI read the schema the same way.

**Strengths:** Broad database coverage across SQL and NoSQL engines, so you rarely need a second tool; Genuinely useful AI layer: natural-language queries, query fixing and automatic charting in one place; Table and chart components are open source and embeddable in your own applications; Strong security posture with SOC 2 Type 2, HIPAA, encryption, role-based access and private AI models

**Limitations:** No public self-serve pricing, so you must contact sales to get started commercially; The natural-language layer is only as good as the underlying schema documentation; Self-hosting is limited — the managed product is the main path, which may not suit air-gapped environments
