Components, variants, styles and variables parity

Last reviewed: 2026-10-10 · Last updated: 2026-10-11 · Change: minor (team libraries on the server, library usage and swapping a library; extended collections, variables import/export, gradient stops and variant properties bound to variables) · Target: Figma Design (desktop app 126.10.7)

Design systems are why teams adopt Figma. Components: breadth ~95%, ready ~68%. Styles and variables: breadth ~92%, ready ~72% (estimated). QA'd with a synthetic design system of ~300 components used 2,000 times (crates/engine/src/synthetic_ds.rs, components_scale_tests.rs); not with real libraries. Remaining: 7–14 h here, plus team libraries' tail (4–8 h, partly after accounts).

Components and variants

Feature	Status	Notes
Create component, instances, detach, reset, go to main, restore main, push changes	done
Per-layer overrides with reset; kept across main edits, nested swaps, copy/paste	done	main edits match a full rebuild exactly at 2,000 instances
Component sets / variants, add variant, switch	done
Properties: boolean, text, instance swap (preferred values), variant	done
Slots (preferred components, fill menu, kept across updates)	done	Figma 2025 feature
Exposed nested instances	done
Descriptions	done
Instance swap: panel, Alt-drop from Assets	done
Assets panel: thumbnails, search, drag into frames and auto layout slots	done	virtualized
Instances pasted into other files follow their mains	done	missing main restorable
Component playground (try properties without placing)	missing	1–2 h
Real-world libraries QA	not checked	gaps #3

Libraries

Feature	Status	Notes
Publish a file's components, sets, styles and variables (per-asset versions)	done	as local library files
Enable a library in a file; read-only linked copies	done
Library updates available; overrides kept	done
Team libraries: publish to a figcraft-server under the file, enable by a share link (a view link reads it), background update checks	done	server.md; no team-wide library list or accounts (gaps #10)
Library analytics	partial	instances per component and the files using them, as apps report them; nothing over time, no detach counts
Swap library (instances, styles and variables to another library's of the same names, overrides kept)	done	what has no match stays and is listed; one undo step

Styles and variables

Feature	Status	Notes
Paint, text, effect, grid styles; style picker; text styles on character ranges	done
Variables: colour, number, string, boolean; collections, modes, aliases, scopes, groups	done
Bindings: fills, strokes, effects, opacity, padding, gaps, sizes, radius, font size, line height, letter spacing, text, visibility, layout grids, instance properties	done
Explicit modes per frame, library collections' modes	done
Gradient stops and variant properties bound to variables	done	a stop's binding follows it when earlier stops are removed
Extended collections	done	library collections; overrides per mode with reset; follow library updates; modes inherited. New library variables arrive with the next other update (gaps #14)
Variables import/export (JSON)	done	the REST local variables shape (round-trips; merges by collection, mode and variable name); CSS custom properties export
Expressions in prototype set-variable actions	done	see prototyping-parity

Revision history

Date	Change	Summary
2026-10-11	minor	Team libraries on figcraft-server (publish under the file, enable by a share link, updates with overrides kept), usage counts per component and file, and swapping a library by names (gap 10)
2026-10-11	minor	Extended collections, variables import/export (JSON, CSS) and gradient stop and variant property bindings landed: styles and variables breadth ~85% → ~92%, ready ~70% → ~72%; remaining here 10–20 h → 7–14 h
2026-10-10	major	Created from the 2026-10-10 re-measure
