- Add components for each software module
- Show provided and required interfaces (lollipop/socket)
- Connect components by dependency
- Group components into subsystems
- Note ports and connectors where relevant
- Interface notation built in
The library includes provided/required interface shapes so component contracts are explicit and easy to read.

FAQs about Component Diagram Templates
They are. You can access and edit the majority of component diagram templates for free on a basic account, with no download needed. Premium templates and some pro features are available on paid plans if you need them later.
Absolutely. Your component diagram exports as PNG, JPEG, PDF or SVG, so you can insert it into Word or PowerPoint, attach it to documentation, or share it as a standalone file.
Component templates describe software organization:
- Module structure - how software is partitioned
- Interfaces - what each component provides or needs
- Dependencies - which components rely on which
- Subsystems - grouping of related components
- Service boundaries - for microservice designs
A lollipop (circle) is a provided interface—functionality a component offers; a socket (half-circle) is a required interface—functionality it needs. Connecting them shows how components depend on one another.
