The Verdict
Eraser is built for engineering teams and solution architects, with a focus on diagrams-as-code and ai-diagrams. Gamma targets professionals and startups and leads with ai-generation and templates.
Both tools come in at similar price points ($10/mo for Eraser, $10/mo for Gamma), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
