## 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

## TestFit

TestFit is a real estate feasibility platform built for the earliest stage of a development deal — the point where you need to know quickly whether a site is worth pursuing. Instead of waiting weeks for a preconstruction team to produce a first draft, you map a parcel or draw a boundary, choose a typology, and let the software generate a complete, editable site plan with buildings, roads, turning radii, parking and topography. TestFit's own customers describe cutting initial site sizing from three to four weeks down to about ten minutes, and the platform reports usage across 6,200+ users.

The product is organised around three solvers. Site Solver handles automated feasibility and deal evaluation using generative design and detailed building presets. Parking Solver concentrates on surface and structured parking layouts, custom stalls and drive aisles. Urban Planner is the entry point for quick massing work, with 2D and 3D visualisation, road layouts, a yield estimator and unlimited users. Around those sit optional add-ons: Site Intelligence supplies parcel, environmental and zoning data plus 3D terrain and cut-and-fill analysis; Pro Forma live-links financials to the plan and imports your own Excel templates; and the MCP Connection lets you prompt site plans from an AI assistant.

Flipping the traditional workflow matters here — TestFit validates a pro forma against an actual physical layout rather than an assumed one, which is what makes the takeoffs for parking, infrastructure and earthwork worth trusting early. Approved layouts then flow into Revit, SketchUp, AutoCAD, Excel or PDF so the concept work survives into documentation, and live feasibility reports keep consultants and stakeholders aligned. Layouts cover multi-family, single-family, industrial, retail, hotel, data center and parking typologies.

**Pricing & Plans:** Paid, quote-based at the top end. Urban Planner is $75/month and Parking Solver $195/month, both billed monthly; Site Solver starts at $15,000/year and Site Solver Portfolio at $20,000/year, billed annually. Add-ons: Site Intelligence +$150/month, Pro Forma +$170/month, MCP Connection +$100/month.

- **Generative site planning:** Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
- **Parking Solver:** Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
- **Site Intelligence data:** Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
- **Live-linked pro forma:** Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
- **Takeoffs and direct integrations:** Generate cost estimates for parking, infrastructure and earthwork early, and push approved layouts to Revit, SketchUp, AutoCAD, Excel or PDF.

**Strengths:** Turns site feasibility from a multi-week exercise into an hours-long loop, enabling far more alternatives per budget; Financials are validated against a real generated layout instead of a rough assumption; Approved plans push straight into Revit, SketchUp, AutoCAD, Excel and PDF, so early work is not throwaway; Comprehensive typology coverage, from multi-family and industrial to data centers and structured parking

**Limitations:** Entry price for automated feasibility starts at $15,000/year, which puts full generative design out of reach for very small teams; Site Intelligence data layers such as parcel, flood zone and zoning coverage vary by country; Training and support are English-only and operate during U.S. business hours; Generative design and detailed typology solutions are gated to the Site Solver tier upward
