Eraser vs Flowchart Fun (2026): which should you pick?

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

Pick Flowchart Fun if

• Fits if you would rather type a diagram than drag boxes
• Works for quick process charts that you export as an image

Look elsewhere if

• Tight if you stay free, because the editor resets each day
• Skip it if you want a drag-and-drop whiteboard, as this is a text editor
• Watch out: AI creation, watermark-free export, local files and data import are all Pro
• Watch out: the page does not say how the $2 a month is billed
• Skip it if you want a desktop or phone app, as none is listed

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.

Flowchart Fun

• On the Free plan the editor is a daily sandbox that resets each day; permanent flowcharts need Pro.
• Watermark-free export, AI creation, local files and data import are Pro features.
• The pricing page does not say whether $2 per month is billed monthly or yearly.
• It runs in a browser; no desktop or mobile apps are listed.

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.

Flowchart Fun

Text-to-flowchart editor

Charts are written as text in an editor and drawn alongside it, covering flowcharts, mind maps and process diagrams.

AI creation and editing

On Pro, AI and dictation can generate and edit diagrams from a written description.

Data import

Pro can import data from Visio, Lucidchart and CSV files.

Export options

PNG and JPG export and SVG export with embedded fonts are listed on the Free plan; Pro removes the watermark.

Local files and sharing

Pro can save and load local files, and offers full-screen, read-only and template sharing.
