Short answer: for a free Figma alternative, use Inkscape for offline vector UI frames—we exported a 390×844 phone frame to PNG (8,707 bytes) with no login. For browser collaboration closest to Figma’s job, evaluate Penpot’s $0 Professional plan on penpot.app/pricing—needs signup; we did not create an account (not tested). Lunacy is free per Icons8 docs with optional cloud/graphics plans. Affinity is free for individuals per affinity.studio (docs-only). Full list: Figma alternatives.
How we ordered the tools: the tool we tested hands-on (Inkscape) comes first, then docs-only options: Penpot (closest to Figma’s browser collaboration), Lunacy and Affinity. None of these products is ours.
Figma’s moat is multiplayer + components + Dev Mode. Free tools usually nail vector frames and SVG ownership first. If your blocker is live cursors and organization libraries, Inkscape will feel like the wrong product—say that before cancelling seats. Role splits: Figma vs Framer (design system vs site builder), Figma vs Sketch (web multiplayer vs Mac-native), Canva vs Figma (templates vs UI).
What it replaces: Figma for single-designer vector frames, icons and SVG export—especially on Linux without SaaS.
What we saw: Inkscape 1.4 rendered a hand-written SVG (dark phone frame, inputs, primary button) to PNG at 390×844 (8,707 bytes) with no network and no account. Proof of an offline UI-mock path—not auto-layout or component variants.
What it lacks: multiplayer cursors, Dev Mode inspect, FigJam, variables/modes.
Get it: inkscape.org (GPL; Windows, macOS, Linux).
penpot.app/pricing lists Professional $0/user/month and Unlimited $7/editor/month (cap on that page). Open-source collaborative UI design closer to Figma than to Canva templates. Hosted cloud still needs an account; self-host is the account-controlled path per Penpot’s materials—we did neither. Same blocker noted on free Canva alternative.
icons8.com/lunacy lists Windows, macOS, Linux and browser. Docs: app free for personal and commercial use; personal cloud $4.99/month; graphics $9.99/month; free-tier graphics may need attribution per subscriptions docs. Markets Figma import—we did not install or import.
get-affinity / affinity.studio: free for individuals; Windows/macOS; Canva account called out on get-affinity pages. Not a multiplayer .fig replacement.
Framer and Sketch are not “free Figma alternatives” in the free-tool sense—see the vs pages. Photopea and other browser clones appear on listicles; we did not test them and they are not in the tools table.
For offline UI work with no login, Inkscape is the pick: we exported a 390×844 phone frame to PNG with it on Linux. It does not replace Figma’s live multiplayer or Dev Mode; for browser collaboration, Penpot is the closest free option, but it needs an account and we did not test it.
Debian 13, CPU-only. Inkscape 1.4 SVG→PNG UI frame. Penpot/Lunacy/Affinity/Figma: official pages only on 2026-10-14. No Penpot account. Same test files as Figma alternatives.
No Penpot account. Lunacy and Affinity not installed. No .fig import attempt. Inkscape test is static frame SVG→PNG, not auto-layout or multiplayer.
Inkscape 1.4 (Debian 1.4-6) exported a 390×844 SVG phone UI frame to PNG (8,707 bytes) on a CPU-only Linux machine with no Figma account—same evidence as figma-alternatives. Penpot was not tested: hosted app needs signup (tested:false). Lunacy and Affinity reviewed from official sites/docs only on 2026-10-14. Figma Starter Free and Professional Full seat $16/mo from figma.com/pricing. Free-only tools table—paid Framer/Sketch compares are separate pages.
