Is Eraser.io worth the price?
Eraser fills a specific niche: technical diagramming with a code-first approach and AI generation.
The diagram-as-code feature lets you write diagrams in a markdown-like syntax, which appeals to developers who prefer text over drag-and-drop. The AI diagram generation is the headline feature, describe what you want in natural language and get an architecture diagram, sequence diagram, or flowchart.
The main question is whether you need a dedicated diagramming tool when Mermaid.js (free) or Excalidraw (free) cover basic needs.
Hidden Costs & Gotchas
Free tier 3-file limit is very restrictive, most users outgrow it within a week of active use, making it function more as a trial than a permanent free plan
AI diagram generation counts are per month with no rollover
Starter gets 40, Business gets 250. Each regeneration or iteration counts against your limit, so refining a single diagram can consume 3-5 credits
API calls on Starter and Business are usage-based with additional charges, pricing is not transparent on the main pricing page
Custom icons are capped
20 on Starter, 100 on Business. Teams with extensive design systems or branded diagrams may hit this limit
Version history on Starter is only 90 days, after that, older versions are permanently deleted. Only Business tier offers unlimited history
No offline mode
all work requires internet connection. Diagrams are stored in Eraser cloud, not locally
