## 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

## Sekai

Sekai is built around a simple idea: interactive content should be immediate. Instead of downloading a game or installing a creative suite, you open a link, play or build, and share the result. The homepage surfaces top creators of the week alongside curated categories — meme, relax, art, strategy, action, puzzle, simulation, casual, sports, racing, card and board — so there is always something to open within a click.

The creation side is what distinguishes Sekai from a plain game portal. Users can start from scratch or remix an existing creation, which has produced a catalogue heavily shaped by collaborative iteration: meme stretchers, ragdoll sandboxes, sticker canvases, piano and synth toys, quizzes and simulator games all appear in dozens of community-made variants. That remix loop keeps the library growing without relying on a central studio.

Sekai is distributed as a web platform and as iOS and Android apps, so the same link works on a phone or desktop. Creations are lightweight, load fast on modest hardware and are designed for quick sharing — which suits classrooms, group chats and creative experimentation as much as gaming.

**Pricing & Plans:** Browsing, playing, creating and remixing are free. An account is optional and is used mainly for managing drafts and published creations.

- **Endless discovery feed:** A constantly updated feed of trending creations, top creators and curated categories such as meme, relax, strategy, action and puzzle.
- **Create and publish your own app:** A studio that lets you build a playable mini-app, then publish it to the community in minutes.
- **One-tap remixing:** Take any published creation, change it and re-release your version — the engine behind most of the catalogue.
- **Instant play, no download:** Everything runs in the browser with no install, and the same creations work on iPhone and Android through the Sekai app.
- **Creator community and profiles:** Profiles, plays and creator rankings turn the catalogue into a social space rather than a static gallery.

**Strengths:** Zero friction: no downloads, installs or launchers to play or create; Remix culture gives the catalogue constant variety; Fast, lightweight creations that run on desktops and phones alike; Broad creative range from games to polls, stickers, piano toys and spin-the-wheel tools

**Limitations:** Curation and discovery can feel chaotic because anyone can publish; Many creations are remixes of the same trending ideas; Quality varies widely between top creators and casual experiments; CloudFront-edge blocking occasionally trips automated crawlers
