The Full Ranking
1. Penpot — Best Overall Design Tool
Penpot is an open-source design platform that rivals Figma. It’s SVG-native, supports real-time collaboration, and includes components, design systems, prototyping, and a CSS inspect mode for developer handoff. Unlike Figma, everything runs on your infrastructure — no vendor lock-in, no usage limits, no subscription fees.
The Docker setup requires PostgreSQL and Redis but is straightforward. Performance is excellent with 4-8 GB RAM. The interface feels familiar if you’ve used Figma or Sketch. Vector editing is precise, components are reusable, and collaboration works smoothly across teams.
Pros:
- Complete design tool with prototyping and developer handoff
- Real-time multiplayer editing
- SVG-native (cleaner exports, better web compatibility)
- Components and design systems built-in
- Active development and growing community
- MPL-2.0 license (open source)
Cons:
- Steeper learning curve than Excalidraw
- Requires PostgreSQL and Redis (more complex stack)
- Plugin ecosystem is smaller than Figma’s
- Higher resource requirements
Best for: Teams doing serious UI/UX work, prototyping web/mobile apps, or replacing Figma with self-hosted infrastructure.

2. Excalidraw — Best for Sketching and Diagrams
Excalidraw is a virtual whiteboard with a hand-drawn aesthetic. It’s perfect for quick diagrams, brainstorming sessions, architecture sketches, and collaborative whiteboarding. The interface is minimal — you draw shapes, add text, connect arrows, and export PNG or SVG.
The key difference from Penpot: Excalidraw is not a design tool. It’s a sketching tool. You can’t build pixel-perfect UI mockups, but you can rapidly communicate ideas with drawings that feel approachable and informal.
The self-hosted version stores nothing server-side — all data lives in the browser or exported files. Deployment is trivial. Resource usage is minimal (20-30 MB RAM).
Pros:
- Instant startup, zero learning curve
- Hand-drawn aesthetic makes sketches feel approachable
- Real-time collaboration built-in
- Exports to PNG, SVG, and shareable links
- Extremely lightweight
- MIT license (fully open source)
Cons:
- Not a full design tool — can’t do precision UI work
- Limited text formatting
- No components or design systems
- No persistent server-side storage by default
Best for: Quick diagrams, brainstorming, technical sketches, architecture diagrams, whiteboarding sessions.

Use Cases
Choose Penpot If…
- You’re replacing Figma or Adobe XD with self-hosted infrastructure
- You need components, design systems, and reusable elements
- Your team does UI/UX design for web or mobile apps
- You want prototyping with clickable interactions
- Developer handoff with CSS specs matters
- You need precise vector editing and typography control
Choose Excalidraw If…
- You need quick diagrams and sketches
- You’re brainstorming or whiteboarding with a team
- You want a hand-drawn aesthetic that feels informal
- You’re documenting architecture or technical concepts
- You want minimal resource usage and instant startup
- You don’t need persistent server-side storage
Different Needs, Different Tools
These tools serve different purposes. Penpot is a full design platform — you build mockups, prototypes, and design systems. Excalidraw is a sketching tool — you communicate ideas quickly with drawings.
If you’re building an app, website, or product, use Penpot. If you’re explaining a technical concept, sketching an architecture, or brainstorming, use Excalidraw. Many teams run both.
How We Evaluated
We tested both tools with:
- Multi-user collaboration sessions (designers and developers)
- Typical workflows (UI mockups in Penpot, technical diagrams in Excalidraw)
- Export quality (SVG and PNG from both tools)
- Resource usage under load (4-user sessions)
- Documentation quality and community support
We prioritized: real-time collaboration reliability, export quality, ease of self-hosting, resource efficiency, and feature completeness for the intended use case.
Frequently Asked Questions
Can Penpot import Figma files?
Yes. Penpot has a built-in Figma importer that converts .fig files to Penpot’s SVG-native format. The import handles frames, components, auto-layout, and text styles. Some complex Figma-specific features (variants, certain auto-layout behaviors) may need manual adjustment after import. For most design files, the conversion is seamless enough to start working immediately.
Does Excalidraw support real-time collaboration?
Yes. Excalidraw includes real-time collaboration — share a link and multiple users draw simultaneously with live cursors. The self-hosted version requires configuring a WebSocket server for collaboration (excalidraw-room). For the simplest setup, use Excalidraw’s built-in collaboration which stores data in the browser. Each session gets a shareable URL.
How much RAM does Penpot need for a design team?
Plan for 4-8 GB RAM for a small team (2-5 users working concurrently). Penpot runs PostgreSQL, Redis, and the application server. A single designer working alone can get by on 2 GB. For teams of 10+, allocate 8-16 GB. The main memory consumer is the backend processing SVG operations — complex files with many layers use more resources.
Can I use Penpot offline?
No. Penpot is a web application that requires a server connection. All design work happens through the browser connected to your Penpot instance. If your server goes down, you can’t access your designs until it’s back. For offline design work, export your projects regularly as SVG files — these can be opened in any vector editor (Inkscape, Illustrator) as a fallback.
Is Excalidraw suitable for technical architecture diagrams?
Yes — it’s one of its strongest use cases. The hand-drawn aesthetic makes architecture diagrams feel approachable rather than intimidating. Arrow connectors, shape snapping, and text labels handle cloud architecture, system design, network topology, and database schema diagrams well. Many engineering teams use Excalidraw for RFC documents, design docs, and whiteboard interviews.
Can I self-host both Penpot and Excalidraw together?
Yes, and many teams do. They serve different purposes: Penpot for polished UI/UX design work, Excalidraw for quick sketches and brainstorming. Run both in Docker on the same server. Excalidraw adds negligible overhead (20-30 MB RAM). Together they replace Figma (Penpot) and Miro/FigJam (Excalidraw) at zero software cost.
