DGM
Free web-based sketchnoting and diagramming tool with AI code generation from diagrams
DGM is a practical pick for solo developers and designers who want free hand-drawn diagrams plus a dose of AI code generation. The Frame0 addition makes it a credible Balsamiq alternative for low-fi wireframes. But collaboration feels experimental and cloud features are basic, so hold off for large team workflows. If you need robust collaboration or deep integrations, consider Miro or Lucidchart instead.

Skip DGM if you need enterprise-grade collaboration, deep integrations with project management tools, or a desktop app for offline diagramming.
The free plan limits cloud documents to 3, so you'll quickly hit a wall if you need more cloud storage without paying.
DGM's pricing is friendly for solo users and small teams: the free local tier is genuinely free forever, and the $4/mo Basic plan offers cloud storage and CDN publishing. Compared to Lucidchart's $9/mo starter, DGM undercuts significantly, but lacks collaboration depth.

About DGM
DGM is a browser-based sketchnoting and diagramming tool for professionals who want to turn rough ideas into visual notes and technical diagrams quickly. It's currently in beta, but the core is already solid: smart shapes carry constraints, properties, and even scripts, plus pre-built libraries for UML, ERD, Flowchart, and UI Wireframe. The hand-drawn aesthetic keeps outputs approachable, and theme-adaptive colors automatically adjust to light or dark mode. With Frame0, DGM also includes a streamlined low-fidelity wireframing tool, positioning itself as a modern Balsamiq alternative for rapid UI sketches. A standout feature is the experimental AI assistant, which uses OpenAI's GPT-4 Vision to generate code directly from your diagrams. Sketch a flow or architecture and you get a starting point for implementation without leaving the canvas. The AI is still marked experimental, so treat it as a productivity nudge rather than a full replacement for your IDE. DGM runs entirely in the browser. The free local tier is genuinely free forever—export to PNG and SVG, use public libraries, publish images to the web, and keep 7 days of revision history, all at $0. If you want cloud storage, the Basic plan at $4/mo bumps you to 200 cloud documents, automatic saving, and CDN publishing. Real-time collaboration exists but is explicitly experimental. Paid plans are coming soon, but the current pricing is transparent and affordable. For people who wireframe, DGM is a two-in-one: technical diagramming plus rapid UI sketching. Compared to Excalidraw or Diagrams.net, it adds AI code generation and smarter shapes, but it's younger, lacks a desktop app, and its collaboration and integration story is still maturing. If you're a solo developer or designer looking for a free, hand-drawn diagramming tool with a dash of AI, DGM is worth a try.
Behind the Verdict
We'd reach for DGM when we need to sketch a diagram quickly and want the option to generate starter code from it. The AI assistant is still experimental, but it's genuinely useful for turning a rough flow into a scaffolding for implementation. The hand-drawn style keeps things informal, which works well for internal documentation and early-stage design discussions. Where it bites is collaboration. Real-time co-editing is labeled experimental, so we wouldn't bet a team's workflow on it yet. The free tier's cloud storage is limited to three documents, which forces heavy users to either stick to local files or upgrade to the $4/mo Basic plan. That's still cheap, but it's a reminder that the tool is young. Compared to Excalidraw, DGM adds AI code generation and smarter shapes with constraints and scripts. Excalidraw is more mature and has a broader community, but it doesn't generate code. Diagrams.net is feature-rich but has a steeper learning curve and no AI hook. DGM's edge is the combination of a hand-drawn feel and AI assistance, all in a simple web app. The Frame0 wireframing tool is a nice bonus. It's low-fi by design, so don't expect interactive prototypes. It's for quickly laying out UI structure, not for pixel-perfect design. If you need that, you're better off with Balsamiq or Figma. One thing we wish DGM had is a desktop app. It's browser-only, which is fine for most, but offline work is limited to local files you've opened in the browser. If you need to work on a plane or in a spotty network, that's a real constraint. In practice, DGM is best for solo developers and designers who want a free, AI-assisted diagramming tool. If you're in a team that needs reliable collaboration and integrations, you'll grow out of it fast. Keep an eye on it as it matures, but

Switching to or from DGM
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Excalidraw: Import scenes via copy-paste or manually recreate since DGM uses smart shapes, not freehand only.
- →From Diagrams.net: Rebuild diagrams using DGM's libraries; there's no direct import, but you can paste text and restyle.
- →From Balsamiq: Recreate wireframes in Frame0, which offers similar low-fi fidelity and hand-drawn aesthetic.
- ↗To Lucidchart: Export diagrams as SVG or PNG and import into Lucidchart; use Lucidchart's import features for images.
- ↗To Miro: Import exported SVG/PNG files as sticky notes or images to continue collaboration.
- ↗To draw.io: Export to SVG and convert to editable XML via draw.io's import options if needed.

Featured Head-to-Head Comparisons
Dgm vs Bito
Choose DGM if you're an individual who needs to sketch diagrams and generate code from them; it's free and web-based. Choose Bito if you're on a team using AI coding agents (like Cursor or Claude Code) and need cross-repo context, architectural planning, and Slack integration – Bito's latest updates make it indispensable for modern engineering teams.
Dgm vs Polycam
Polycam and DGM serve entirely different needs. Choose Polycam if you need to create 3D models, floor plans, or digital twins from photos/LiDAR—its AI photogrammetry and HDRI lighting are standout features. Choose DGM if you need to draw technical diagrams (UML, ERD, flowcharts) with AI code generation. They are not direct competitors, so your decision hinges on whether your work is 3D reality capture or 2D diagramming.
Dgm vs Cognition Ai
If you're an enterprise engineering team needing an autonomous AI that plans, codes, tests, and ships production code with a financial guarantee, Cognition AI's Devin is the clear winner. For individual developers or small teams who want to create hand-drawn style diagrams and generate code from them, DGM offers a free, accessible tool. The two serve entirely different needs: end-to-end automation vs. visual diagramming with AI assist.
