Best free Sketch alternatives (open source, self-hosted) 2026

How Sketch compares

FAQ

What is the best free open-source Sketch alternative?

The best open-source alternative to Sketch is Penpot, self-hosted on Railway. Self-host the design file. Penpot is the open-source product-design tool: boards, components, prototypes — Figma, Canva, Adobe XD, Sketch, InVision, and Zeplin without the seat.

Is it free?

The Penpot licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Sketch seat or task bill on this path.

Can I migrate from Sketch?

Yes. Start with the workflows or data you actually use, then cut over. The Penpot stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Sketch links until they expire.

How do I deploy it?

Open the Penpot stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: Penpot (frontend + backend + Postgres + Redis + object storage). A volume for assets. No one-click template in this repo yet — Start on Railway.

What does this replace?

Figma / Canva / Adobe XD / Sketch / InVision / Zeplin. The published small-team estimate on this stack is $1,920 a year.
