PlantUML Diagrams for Confluence

[#1]

What it does

PlantUML Diagrams & Charts for Confluence embeds a full PlantUML editor directly in Confluence. You write plain-text syntax, hit render, and get a clean SVG or PNG diagram — no external tools, no copy-pasting screenshots, no hunting for the right template.

Key capabilities:

• Built-in PlantUML editor — write and render without leaving the Confluence page
• SVG & PNG output — sharp, scalable renders that look great in print and on screen
• Easy in-place editing — update the source text and re-render; changes propagate instantly
• Respects Confluence permissions — integrates with existing page permissions and comments model
• No external tools needed — stay within Confluence for maximum efficiency

Supported diagram types

Who is this for?

Six teams that adopt this immediately — each with a different diagram type and a clear workflow benefit.

SE  Software engineer Backend / full-stack Sequence diagrams Documents API contracts and inter-service flows alongside the Confluence spec page. The diagram lives in the same PR review cycle as the code — no stale screenshots. Example: Client -> API : POST /order API -> DB : insert record DB --> API : order_id API --> Client : 201 Created

SA  Solutions architect Enterprise / cloud Component diagrams Maintains living Architecture Decision Records (ADRs) and system overviews. PlantUML source is version-controlled text — editable by any team member, no license required. Example: package "Data layer" {   [Postgres] - [Redis cache] } [API gateway] --> [Postgres]

PM  Product manager B2B SaaS Activity / flowcharts Maps user journeys and feature flows in PRDs without switching tools. Stakeholders can review the diagram directly in Confluence comments — no Figma access needed. Example: start :User lands on pricing page; if (logged in?) then (yes)   :Show upgrade CTA; else (no)   :Redirect to signup; endif		QA engineer Test automation State diagrams Visualises object lifecycle and edge-case transitions in test plan pages. State diagrams make it immediately obvious which transitions are covered and which are gaps. Example: [*] --> Draft Draft --> Submitted : submit() Submitted --> Approved : approve() Submitted --> Rejected : reject()

TW  Technical writer Developer docs Use case diagrams Embeds actor-level use case diagrams in onboarding guides and SDK docs. Non-engineers can read the diagram immediately; writers update it by editing a few lines of text. Example: actor Developer actor "End user" Developer --> (Authenticate via OAuth) "End user" --> (View dashboard)		DM  Data / ML engineer Platform team Class diagrams Documents entity relationships and feature store schemas alongside data pipeline specs. Class diagrams replace ad-hoc ERD screenshots that go stale the moment the schema changes. Example: class Event {   +String event_id   +DateTime timestamp   +String user_id } Event "1" --> "*" Feature
