Is Eraser.io worth the price?

70/100

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. At $15/month (annual) for Starter, it is reasonably priced but the 3-file limit on Free makes the free tier feel more like a trial than a usable product.

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

Per-user pricing means costs scale linearly with team size

a 10-person team on Business pays $450/month ($5,400/year annual) or $600/month monthly

No offline mode

all work requires internet connection. Diagrams are stored in Eraser cloud, not locally
