Cloudcraft vs Eraser (2026): which should you pick?

Pick Cloudcraft if

• Fits if you already pay for Datadog and want live architecture maps
• Works for cloud engineers who need diagrams that follow infrastructure changes

Look elsewhere if

• Skip it if you don't use Datadog, as there's no separate plan
• Not for you if you want a freeform whiteboard, because it only maps existing infrastructure
• Watch out: logs, cost, security, APM and GPU overlays need the matching Datadog subscription
• Watch out: the diagrams depend on cloud accounts being connected through Datadog first

Pick Eraser if

• Fits if you're an engineer who'd rather type a diagram than drag boxes around
• Works for teams whose diagrams have to follow the code, since it reads a connected Git repo

Look elsewhere if

• Pricey if you just want a team whiteboard, at $45 a member a month billed annually or $60 monthly
• Tight if you're staying free, with 3 files, 3 AI credits, 7 days of history, no private files and no GitHub integration
• Watch out: AI past your monthly credits is $60 per 100, and API calls are billed on top of the plan
• Skip it if you need SAML SSO for a small team, as it's on Business Plus, $42 a member a month and sold from 10 seats
• Not for you if you want a desktop or phone app, as Eraser only runs in a browser

Cloudcraft

• Cloudcraft is described as included with Datadog; the pricing page lists no separate paid plan.
• Logs, cost, security, APM and GPU overlays appear only when the matching Datadog subscription is in use.
• It maps existing infrastructure rather than serving as a freeform whiteboard.

Eraser

• The Free plan stops at 3 files and 3 AI credits, keeps 7 days of version history and has no private files or GitHub integration.
• AI use beyond a plan's monthly credits costs $60 per 100 credits, and only on paid plans with usage-based pricing switched on.
• API calls are billed by usage on top of a paid plan: $80 per 100 prompt-to-diagram calls and $20 per 100 code-to-diagram calls.
• The vendor's site lists no desktop or mobile app; Eraser runs in a browser, and SAML SSO needs Business Plus, sold from 10 seats.

Cloudcraft

Automatic diagrams

Maps are built and kept current from the read-only cloud integrations already connected to Datadog, with no agent needed for cloud accounts.

Multi-cloud coverage

AWS, Azure, Google Cloud and Oracle Cloud accounts, plus on-prem environments such as VMware vSphere, can sit on one diagram.

Overlays

Infrastructure, monitors and observability coverage are included; logs, cost, security, APM and GPU overlays follow the Datadog products you use.

Export and embed

Export diagrams to SVG and PDF, or embed live diagrams in Datadog dashboards.

AI and MCP access

Ask Bits AI questions beside a diagram, or connect agents such as Claude Code and Codex through the Datadog MCP Server.

Eraser

AI diagram generation

A prompt, an image or a file such as Terraform or a database schema is turned into an editable diagram, which can then be refined through AI chat or by hand in the visual editor.

Diagram-as-code

Architecture, sequence, flowchart, ERD and BPMN diagrams each have a text syntax, so a diagram can be read, compared and edited as code. It is included on every plan.

Canvas with Markdown notes

A file holds one infinite canvas and a note editor with Markdown support. Figures from the canvas can be embedded in the document, and files export to PDF, PNG, SVG or Markdown.

Codebase diagrams and Eraserbot

Diagrams can be generated from a connected Git repository. Eraserbot watches chosen files and comments on pull requests with updated diagrams when they change.

REST API and MCP server

The API renders a diagram from a prompt or from Eraser's diagram code. The MCP server lets Claude, Cursor or ChatGPT create, search, update and export diagrams.

Real-time collaboration and guests

Members edit together in real time and leave comments and mentions. Guests are free on every plan and can edit or comment only on files they are invited to.
