What Eraser Labs does
Eraser Labs, Inc., operating as Eraser (eraser.io), is a San Francisco-based software company founded in 2020 that provides an AI copilot for generating and maintaining technical diagrams and documentation for software engineering teams. The platform produces cloud architecture diagrams, entity-relationship diagrams, flowcharts, sequence diagrams, BPMN, and design documents from natural-language prompts or pasted code, using OpenAI's GPT-4 as the underlying model and outputting editable diagram-as-code that supports Mermaid, PlantUML, and a proprietary Eraser DSL. Outputs are version-controllable via GitHub and auto-updated through Eraserbot, a CI integration that syncs codebase diagrams with code changes.
The business runs on a tiered freemium SaaS model: a Free Plan with limited usage, Starter and Business tiers for paying teams, and an Enterprise tier offering SOC 2 Type 2 certification, SAML SSO (Microsoft Entra, Okta), multi/single-tenancy and BYOC private cloud deployment, and custom AI outputs. Distribution is hybrid — self-serve product-led growth for individuals and small teams via free tools (DiagramGPT, Free Diagram Maker, Git Diagrammer) and SEO-driven landing pages, plus enterprise field sales for larger organizations through a Book Demo CTA. In 2025, the company extended distribution through a Diagramming API and an MCP Server that embeds Eraser inside AI coding agents including Claude Code, Cursor, Codex, GitHub Copilot, Kiro, and Microsoft Copilot Studio.
Eraser is bootstrapped with no external venture capital funding. The company has reached $2.8M in annual recurring revenue with a disclosed $8.3M valuation and serves customers including Microsoft, Amazon, Visa, McKesson, KPMG, Gartner, Salesforce, and Thermo Fisher Scientific. Headcount is 11–50 employees, and the entity is incorporated in California with headquarters at 548 Market St, San Francisco.

Eraser Labs competitors and assessment
Company assessmentOthers
- Mermaid: Open-source text-based diagramming syntax widely embedded in developer tools and documentation platforms. Not a direct competitor for paid diagramming, but functionally competes for the same diagram-as-code workflow that Eraser monetizes.
Direct peers
- draw.io (diagrams.net): Free, widely adopted diagramming tool with deep integrations into Confluence, Google Workspace, and VS Code. Directly competes with Eraser's core diagram creation and free diagram maker offerings, particularly among cost-sensitive engineering teams.
- Whimsical: Collaborative diagramming and wireframing tool used by product and engineering teams. Closely comparable in target persona (engineers, product managers) and visual collaboration use cases overlapping with Eraser's multiplayer canvas.
- Lucidchart: Lucid's flagship diagramming product targeting enterprise architects, engineering, and product teams. Most direct functional competitor to Eraser's AI Diagrams and diagram-as-code positioning, with significantly larger scale and enterprise footprint.
Broad incumbents
- Miro: Broad collaborative whiteboard platform with extensive diagramming, technical templates, and AI features. Competes with Eraser for engineering team documentation and architecture workflows as part of a much wider collaboration portfolio.
- Notion: Connected workspace with documents, databases, and now Notion AI for content generation. Overlaps with Eraser's AI Documents and design doc use cases, and is an integration partner that could also be a competitor as it embeds more diagram capabilities.
- Microsoft Visio: Long-standing enterprise diagramming product bundled into Microsoft 365 and increasingly enhanced with AI capabilities. Competes with Eraser for enterprise architecture diagrams, especially inside Microsoft-centric Fortune 500 environments.
Emerging players
- Structurizr: Diagram-as-code platform based on the C4 model for software architecture visualization. Closely aligned with Eraser's diagram-as-code paradigm and enterprise architect persona, though with a more opinionated architectural framework.
- IcePanel: Architecture diagramming tool focused on system-level views for engineering teams. Highly comparable to Eraser's enterprise architect and DevOps use cases, with similar emphasis on keeping architecture documentation aligned with code and infrastructure.
- Excalidraw: Open-source hand-drawn style whiteboard popular with developers and engineering teams. Overlaps with Eraser on collaborative diagramming for technical users, especially for early-stage teams that prefer free, lightweight tools.
