## 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

## Database Sample

DatabaseSample tackles the blank-page problem in data modelling. Instead of opening an empty designer, you search a catalogue of 1,847 published database designs — each with an ER diagram, table and column details, and an automated review that flags missing keys, absent indexes and other structural problems. Nearly a thousand multi-table sample datasets are also available with intact foreign keys, shipping as CSV, JSON, SQL for four dialects, a Prisma seed or a Django fixture, all released under CC0 with no account required.

Around that library sits a working toolkit. The DBML text editor renders a diagram as you type, the SQL playground runs queries in PostgreSQL or SQLite directly in the browser and shows the query plan, and share links bundle the schema, query and result into one reproducible URL. Field generators produce valid UUIDs, localised names, non-uniform numbers and test card data, while SQL dialect converters translate DDL between MySQL, PostgreSQL and SQL Server and spell out the semantic differences.

The AI side is the AI Generator and Dataset Studio. Describe the dataset you need and the model proposes a schema; the Free plan lets you run three designs a day and download a 50-row sample of every table, while Pro and Team plans raise limits, unlock complete datasets and private downloads, and add a stronger model inside the editor. Team workspaces add roles, comments and review requests, and a GitHub Action can review pull requests that change a shared schema.

**Pricing & Plans:** Freemium. All published database designs and datasets are free to download with no account. Dataset Studio generation starts free (50-row samples, 3 designs/day); Pro is $19/month for complete datasets and 25 designs/day; Team is $15 per user per month ($45/month for 3 seats) with shared workspaces; Education is free for verified school email addresses. Yearly billing costs ten months' price; Team is 50% off for verified educators.

- **1,847 database design catalogue:** Browse ready-made schemas by subject, each with an ER diagram, full column details and an automated design review that calls out missing keys and indexes.
- **AI schema generator and Dataset Studio:** Describe the data you need in plain English, compare generated designs, and download generated rows with working foreign keys in CSV, JSON, SQL, Prisma or Django formats.
- **In-browser DBML editor and SQL playground:** Write schema as DBML text and watch the diagram update live, then query generated rows in PostgreSQL or SQLite, inspect the query plan and share the whole thing as one reproducible link.
- **997 multi-table sample datasets under CC0:** Deterministically generated datasets with valid foreign keys, available in eight download formats with no account, no attribution and no restrictions.
- **SQL dialect converters and field generators:** Translate DDL between MySQL, PostgreSQL and SQL Server with differences called out, and generate UUIDs, localised names, skewed numeric distributions and standard test card numbers column by column.

**Strengths:** The design catalogue, sample datasets and download formats are free with no account, making it easy to evaluate before paying anything; Sample data is genuinely relational — foreign keys stay intact across tables, so it loads and queries like real data; Tooling is unusually complete for one site: catalogue, editor, diagram, SQL playground, converters, generators and AI design in one place; Transparent, published pricing with a free education tier and yearly billing equal to ten months

**Limitations:** Generated Studio results expire after 30 days on every plan, including paid ones, so output must be downloaded to be kept; The free tier is deliberately narrow — 50-row samples, three AI designs a day and 20 editor AI requests per month; Credit-style daily limits mean large modelling sessions on the Free plan require waiting for the next day
