Low confidence — this score is based on limited public data (mostly aggregate ratings, with little independent discussion or review detail), so it may not reflect real-world quality.
What it is
Overview
A diagram generator that turns text prompts into technical architecture diagrams using a diagram-as-code approach. Software architects and DevOps engineers use it to create system diagrams, network topologies, and cloud architecture visuals that can be version-controlled like code. The tool targets engineering teams who need documentation that stays current with their codebase through automated generation rather than manual drawing.

“Hello fellow diagrammers, Over the past few years, I’ve gradually taken on more of an architectural role at my (rather small) company. Until now, I’ve mostly relied on draw.io—it’s simple, integrates well with Confluence, and is easy enough to use. But let’s be honest: maintainin”
“I've only played with the free version, and it was late last year. I'm also a bit biased. With that, I don't really see the value in their approach. The idea is you describe a system in prose and it generates a diagram of it. Sounds neat, but in practice this gets you very little”
“Graphically it looks really cool. I guess this competes in the same space as https://draw.io and https://eraser.io I was impressed by eraser.io ability to use GenAI to generate software architecture schematics based on a textual description. Where they both fall short in my perso”
“I found a useful tool today after I sifted through a post here from several months ago via my technical diagram query. I’ve worked in the Fortune 100 space for the last several years and diagramming tools have not been easy or fun. I don’t think the AI feature of Eraser was out s”

Questions
Frequently asked
What is Eraser?
Eraser is an AI-powered diagramming tool that creates technical diagrams from natural language prompts using a diagram-as-code approach. It's specifically designed for engineering teams to generate and maintain architecture diagrams, ERDs, flowcharts, and sequence diagrams with consistent formatting and easy maintenance.
Is Eraser free to use?
Yes, Eraser offers a free plan that includes 3 files, 3 AI diagrams, 7-day version history, and unlimited guests. Paid plans start at $15 per member monthly (billed annually) for the Starter plan with unlimited files and 40 AI diagrams.
What types of diagrams can Eraser generate?
Eraser can generate cloud architecture diagrams, entity relationship diagrams (ERDs), flowcharts, process diagrams, and sequence diagrams. All diagrams are created from natural language prompts and use diagram-as-code markup for consistent formatting.
What is diagram-as-code and why does Eraser use it?
Diagram-as-code is a methodology where diagrams are defined using markup code rather than manual drag-and-drop interfaces. Eraser uses this approach to ensure diagrams remain legible and maintainable without manual box-moving, making it easier to keep technical documentation consistent and up-to-date.
Does Eraser integrate with development tools?
Yes, Eraser integrates with GitHub, Notion, Confluence, and VS Code to fit into existing development workflows. It also supports exporting diagrams to multiple formats including PDF, PNG, SVG, and Markdown.
Can I collaborate with my team on Eraser?
Yes, Eraser includes real-time collaboration features and commenting capabilities. The platform also offers an infinite canvas workspace and markdown note-taking with embedded diagram snapshots for team documentation.
How many AI diagrams can I create with each plan?
The Free plan allows 3 AI diagrams, the Starter plan includes 40 AI diagrams monthly, and the Business plan provides 250 AI diagrams monthly. Enterprise plans offer unlimited AI diagrams.
Is Eraser suitable for enterprise use?
Yes, Eraser offers enterprise features including SAML SSO, unlimited version history, flexible deployment options (multi-tenancy and private cloud), and maintains SOC 2 Type 2 certification. Enterprise plans also include dedicated customer success management.
