## 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

## SurfSense

SurfSense is built around a simple idea: a research assistant should not require an account, a cloud upload, or a subscription you cannot audit. You install a normal desktop app for Windows, macOS or Linux — no Docker and no terminal required — and on first launch you pick a model. A small local model downloads once and runs on your CPU, meaning you can literally disconnect the network and keep asking questions about the sources you have already indexed. Alternatively you can paste a key for OpenAI, Anthropic or any OpenAI-compatible endpoint, and that key stays on the machine that uses it.

On top of that index sits a toolkit of outputs. Any set of sources can be turned into a slide deck, a written report, a briefing, a podcast-style audio conversation, a mind map, flashcards, a quiz, a spreadsheet of extracted tables, or a standalone web page. Because generation happens locally, there is no per-minute fee and nothing is uploaded, which matters for lawyers, accountants, consultants and engineers working with case files, ledgers or client documents they are not permitted to send to a vendor.

The free core is genuinely free and open source, with no account and no usage cap. Paid licences exist only to unlock SurfSense's own server-side scraper plugins (among them Google Search, Reddit, YouTube, Instagram, TikTok, Google Maps, Amazon, Walmart, Indeed and a general web crawler) and priority support. Plugins you add yourself — third-party plugins and MCP servers — need no licence. Enterprise agreements mirror the licensing and plugin endpoints inside a customer's own network so that nothing egresses at all.

**Pricing & Plans:** The application and all its updates are free forever — no account, no trial clock, no usage cap. A 14-day plugin licence is included with the free download (email only, no card). An Individual licence costs $60 for the first year and $120 a year thereafter and unlocks every SurfSense plugin plus priority support and one feature-build request per year. An Enterprise deployment is custom-priced and invoiced annually. Self-building from source is also free.

- **Air-gapped, self-hosted operation:** Install a normal desktop app on Windows, macOS or Linux and run it with no account. With a local model you can pull the network cable and keep querying your indexed sources, since nothing is sent to a vendor.
- **Bring your own model, or run a local one:** Choose a bundled local Qwen or Gemma model at first launch, or paste a key for OpenAI, Anthropic or any OpenAI-compatible endpoint. The model is a setting rather than a fixed vendor choice.
- **Twelve artifact formats:** Turn one set of sources into slide decks, reports, briefing notes, podcasts, mind maps, flashcards, quizzes, Markdown, Word, PDF, HTML and spreadsheet outputs — generated and stored locally.
- **Scraper plugins for live sources:** Optional plugins pull research from Google Search, Reddit, YouTube, Instagram, TikTok, Google Maps, Amazon, Walmart, Indeed and the open web, and anyone can register their own MCP server.
- **Open source and enterprise-deployable:** The source is public and auditable, and an Enterprise deployment mirrors licensing and plugin endpoints inside your own network with model and network policy you control and a local audit log of outbound calls.

**Strengths:** Runs fully offline with a local model, so sensitive sources never leave your machine; No account, no sign-up and no usage cap on the core application; Choice of model — bundled local models or your own OpenAI, Anthropic or compatible key; Open source and auditable, with a wide range of output formats from a single source set

**Limitations:** The first local model download and setup step takes time and some technical patience; The most useful scraper plugins sit behind a paid licence, which runs $60 the first year then $120 a year; Collaboration and cloud sync are intentionally absent, so it suits individual work better than shared team workspaces
