Org charts are essential for understanding who reports to whom, how teams are structured, and where responsibilities lie. We've added a dedicated org chart editor to FreeFlowCharts — free, browser-based, no signup.

What is an org chart?

An org chart (organizational chart) is a hierarchical tree diagram that shows the structure of an organization. Each box represents a person or role, and lines connect them to their manager. The CEO (or equivalent) sits at the top; direct reports branch downward.

Common uses for org charts:

Company structure: — CEO → VPs → Directors → Managers → Individual Contributors

Department mapping: — who belongs to which team

Project teams: — temporary structures for cross-functional projects

Onboarding: — helping new hires understand the reporting chain

Board presentations: — visual summary of organizational design

How the editor works

Open freeflowcharts.app/orgchart to get started. You'll see a pre-loaded "Simple Team" template with a CEO, three C-suite reports, and two departments. Click any node to select it, then use the sidebar to change the name, title, or reporting line.

The layout is fully automatic. Every time you add, remove, or re-parent a node, the tree recalculates:

Subtree widths are computed recursively

Children are centered under their parent

Vertical spacing keeps things readable

Colors are assigned by depth level

Templates

Simple Team: — CEO with CTO, CFO, COO and two sub-departments

Department: — Director with two managers, each with staff members

Export options

PNG: — high-resolution raster image, great for presentations

JSON: — structured data with all node relationships

API support

Build org charts programmatically:

curl -X POST https://freeflowcharts.app/api/create-orgchart \
  -H "Content-Type: application/json" \
  -d '{"title":"Engineering Team","nodes":[{"id":"1","label":"VP Engineering","title":"Vice President"},{"id":"2","label":"Frontend Lead","parentId":"1"},{"id":"3","label":"Backend Lead","parentId":"1"},{"id":"4","label":"Dev A","parentId":"2"},{"id":"5","label":"Dev B","parentId":"3"}]}'

The API validates the tree, auto-lays out positions, stores the chart in Firestore, and returns a shareable link with embed code. Export endpoints at /api/export-orgchart/json and /api/export-orgchart/svg return structured data or a rendered SVG.

Constraints

Maximum 100 nodes per chart

Each node needs a unique id and a label

parentId references must point to existing nodes (invalid refs are treated as roots)

Same 30 req/hr rate limit as all other endpoints
