About

Revolutionizes engineering documentation with diagram-as-code, markdown, and GitHub integration

Unfragile Review

Eraser combines diagram-as-code with markdown in a way that actually makes technical documentation feel less like a chore, particularly for teams already living in GitHub. The real innovation isn't the diagrams themselves—it's treating them as version-controlled, collaborative artifacts rather than static images buried in Confluence.

Pros

+Diagram-as-code approach means documentation stays in sync with your workflow and can be diffed like regular code
+Seamless GitHub integration lets you embed and update diagrams directly from your repo without leaving your IDE
+The markdown + diagramming combo creates genuinely useful living documentation that engineers actually maintain

Cons

-The learning curve for diagram syntax is non-trivial—it's powerful but not as intuitive as drag-and-drop tools like Lucidchart
-Export options are somewhat limited compared to established competitors, making it harder to share with non-technical stakeholders or print-friendly formats
