Archboard vs Eraser

Archboard is built for the mixed room: platform engineers and product people on the same hosted canvas, including teammates who never open a repo. You sign in with Google or GitHub. You drop Kubernetes, C4, cloud, and network packs as visual nodes with ports. You share a branded public link on Free and embed on Pro. The document is JSON, not a file that only exists beside application code. Autosave, revisions, and canvas-faithful snapshot export are how that picture lasts. That is the operating model we sell.

Eraser is built for diagrams next to code: diagram-as-code, Markdown notes beside a canvas, GitHub / Notion / Confluence / VS Code hooks, a render API, and an MCP server. Archboard is a visual canvas first: AI agents connect through its MCP server with OAuth and edit the same live canvas the team is looking at, next to people’s cursors, and its document format has a public JSON Schema. Product managers still open that workspace without a repository. Those are different jobs. Architecture teams that need a shared visual language subscribe here.

Price, independently checked in 2026: Eraser Starter is $15 per member per month billed annually, or $20 billed monthly, with Business at $45 / $60 and a Free tier capped at three files (eraser.io/pricing). Archboard Pro is $10 per seat per month or $96 per year for one to five seats. Eraser Business adds SAML SSO at $45 per member per month annually; Archboard Enterprise is $24 per seat per month with a six-seat minimum, plus SLA and dedicated support, and everyone signs in with Google or GitHub. Count seats, sign-in requirements, and whether the canvas must include non-engineers.

Subscribe to Archboard when product and platform need a shared visual language in the browser, with domain packs and a path from Free share to Pro embed to Enterprise seats, without requiring everyone to live in Git.

Archboard wins for mixed platform and product teams. Kubernetes, C4, cloud, and network packs are visual nodes with ports. JSON is the document. Share, embed, autosave, and org seats live on a hosted workspace that people who never open a repo can still use.

Eraser is a repo-adjacent diagram product with a render API. Archboard is a visual hosted workspace that your team and your AI agents edit live. If the org needs a shared architecture language in the browser, subscribe here.
