## 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

## Solarch

Solarch inverts the usual AI coding flow. Rather than generating code and hoping the architecture catches up, it produces architecture first: you draw your backend as a node/edge graph using 21 node types across 8 families and 16 typed relationships, and a default-deny Rules Engine validates every connection as you draw it. Concepts like a controller reaching directly into a database table are simply not drawable, so structural mistakes are caught at design time instead of in code review.

Once a graph is validated, a hybrid code engine takes over. Stage one is a deterministic compiler that turns nodes and edges into a skeleton — DTOs, entities, constructor injection — using no model tokens at all. Stage two applies AI surgically to fill only the empty function bodies, so the algorithmic logic stays yours and roughly 80% of a project ships as boilerplate. Graphs are organised fractally: each node lives in one home tab and other tabs import it as a ghost reference rather than making a copy, which keeps large systems coherent, and semantic zoom lets you move from macro modules down to micro-graphs.

The architecture then travels with you. A VS Code extension shows a revision timeline and live drift findings in the Problems panel; the CLI provides drift guard, two-way sync and deterministic NestJS code generation and can block merges that break the architecture in CI; and an MCP server supplies Claude, Cursor and other agents with the real graph plus the rules, so every write only commits when the edges pass. Type safety runs from the database schema through the API contract to the typed client, and changing a column stops the frontend compiling until it is reconciled.

**Pricing & Plans:** A free-forever tier covers two projects, the live canvas, the AI architect and default-deny validation with no credit card. Paid tiers run Draw at $5/month for unlimited sketchpad use, Build at $20/month for extended AI usage plus code generation and ZIP export, Code at $100/month for full codebase generation, and Team at $30 per seat for shared projects. A 7-day trial applies to paid plans, and Enterprise adds self-hosting, SSO, audit logs, a custom rules matrix and dedicated support.

- **Live node/edge canvas:** Model the whole backend — controllers, services, repositories, tables, DTOs and queues — on one surface with 16 semantic edge types across 8 families.
- **Default-deny rules engine:** An illegal connection such as wiring a controller straight to a table is rejected the instant you draw it, based on 7 anti-patterns and 3 conditional checks.
- **Hybrid code engine:** Stage one compiles the graph deterministically into skeletons with zero tokens; stage two uses surgical AI to fill only the empty function bodies.
- **GraphRAG grounding:** A LangGraph-powered architect grounds every plan in a vector-indexed library of canonical patterns instead of autocompleting from scratch.
- **Developer tooling:** VS Code extension, CLI with drift guard and two-way sync, and an MCP server so AI agents work against the real, rule-checked architecture.

**Strengths:** Architecture is validated before any code is written, so drift is structurally prevented; Deterministic stage-one generation keeps token costs low; Writes commit only when the graph passes the rules, not just when the model feels confident; Same diff engine across editor, CLI and AI agent

**Limitations:** Requires willingness to model the system as a graph before coding; Deterministic generation is currently deepest for NestJS-style backends; The full codebase tier is a serious monthly commitment for individuals
