# Diagrammo
> A diagram-as-code tool. Write plain text `.dgmo` files; get rendered diagrams in a browser editor, a Mac app, your AI tool, or scripts. 51 chart types, 7 palettes. Free. Core library and CLI are MIT-licensed open source.
Diagrammo is built around the DGMO language — a plain-text syntax. Every diagram starts with a first line that declares the chart type (and optional title), followed by data and options. The same `.dgmo` file works across every surface.
## Quick start
- [Browser editor](https://online.diagrammo.app): no install, no sign-up — open it and start typing
- [AI integrations](https://diagrammo.app/ai): one command installs dgmo into Claude Code, Codex, Cursor, or Claude Desktop
- [CLI + npm library](https://diagrammo.app/dev): `npm install -g @diagrammo/dgmo-cli` (CLI, macOS and Linux) or `npm install @diagrammo/dgmo` (library)
- [Desktop app (macOS)](https://diagrammo.app/app): native app with split-pane editor + live preview
One-command AI installers (requires `npm install -g @diagrammo/dgmo-cli` first):
- `dgmo --install-claude-code-integration` — Claude Code + `/dgmo` skill + MCP
- `dgmo --install-codex-integration` — Codex CLI + `AGENTS.md` + MCP
- `dgmo --install-claude-desktop-integration` — Claude Desktop + MCP
## Reference
- Per-chart-type syntax (`https://diagrammo.app/llms/<id>.txt`): plain-text grammar for one type — fetch this, not the full spec, when you know which chart you want. Linked per type below
- [Canonical grammar](https://diagrammo.app/reference): single-URL DGMO spec designed for LLM fetch
- [Full language specification](https://diagrammo.app/llms-full.txt): longer-form grammar in plain text
- [Chart-type guides](https://diagrammo.app/docs): one page per chart type with examples and tips
- [DGMO vs Mermaid / D2 / PlantUML](https://diagrammo.app/compare)
## Choosing a chart type
Match the question to a type, then fetch that type's file from the list below.
- Comparing quantities across categories → bar · over time → line · share of one whole → pie
- Messages between parties in order (API calls, protocols, conversations) → sequence
- A decision or process with branches → flowchart · boxes and arrows with no stricter semantics → boxes-and-lines
- Server/cloud topology with traffic → infra · architecture at context/container/component level → c4
- Statuses something moves through → state · a repeating loop (PDCA, DevOps) → cycle
- Tasks against calendar time → gantt · task network with estimates and critical path → pert · board columns → kanban · tasks × roles → raci
- Events along a line with annotations → event-line · dated eras and ranges → timeline
- Database tables and relations → er · UML classes → class · git branches and merges → version-control
- Who reports to whom → org · ancestry and unions → family
- Two-axis positioning → quadrant · set overlap → venn · stage-by-stage drop-off → funnel · flows between nodes → sankey
- Hierarchy sized by value → treemap · radiating ideas → mindma

What verification unlocks
See how your site is discovered—and control what agents see.
- See your website in the map
Review your indexed topics, nearby publishers sharing headings, measured listing exposure and map snapshots in a private report for your website.
- Control what agents see
Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.

Claim my listing on Agent Web Map for diagrammo.app:
1. POST https://agentwebmap.com/v1/sites/diagrammo.app/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://diagrammo.app/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/diagrammo.app/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/diagrammo.app).
