Eraser vs PlantUML
Eraser is technical diagramming tool for software architecture, system design, and engineering docs, while PlantUML is open-source tool for creating UML diagrams from plain text descriptions. PlantUML is open source and can be self-hosted, giving you full control over your data. Eraser is built for engineering teams creating architecture diagrams and technical documentation, whereas PlantUML targets software architects who need comprehensive uml diagram support.

Pricing: Both Eraser and PlantUML are free, so this decision comes down to features and philosophy rather than budget.
Feature gaps: Eraser offers AI generation, Architecture diagrams and Diagram-as-code that PlantUML lacks. PlantUML brings IDE integration, Open source and Text-based that Eraser does not have.
Open source: PlantUML is open source, meaning you can self-host, audit the code, and avoid vendor lock-in. Eraser is proprietary — you are trusting the vendor with your data and uptime.
Where each tool shines: Eraser's biggest strengths are: purpose-built for technical and architecture diagrams. diagram-as-code generates visuals from text descriptions. PlantUML's biggest strengths are: most comprehensive uml support of any diagramming tool. text-based format integrates with version control.
Watch out for: With Eraser, users commonly note that narrow focus — not for general brainstorming or design. With PlantUML, the main complaint is that steep learning curve for the text syntax.
