    Eraser's AI diagram generation and diagram-as-code are perfect for creating and versioning infrastructure diagrams; free for individual use.

  • Enterprise engineering team using AI agents for multi-repo development
    Pick: Bito

    Bito provides system-level context needed for agents like Cursor and Claude Code, plus on-prem deployment and SOC 2 compliance.

  • Tech consultant creating design docs and diagrams for clients
    Pick: Eraser IO

    Eraser's infinite canvas, collaborative editing, and export options (PNG, PDF) fit client deliverables; Business plan offers custom icons and SSO.

  • Engineering manager scoping epics and generating Jira stories
    Pick: Bito

    Bito's auto-scoping and impact assessment directly break down epics into stories with estimates, integrating with Jira and Linear.
