Keyline Icons
1,435 icons, drawn on one 24×24 grid, in four styles and two corner treatments. Built for shadcn/ui, free under MIT.
keylineicons.com to browse and copy.
| Style | Icons | What it is |
|---|---|---|
stroke | 1,435 | The full set. 2px keylines on a 24 grid. |
two-tone | 1,435 | The stroke drawing over a flat plate at reduced opacity. |
duotone | 1,435 | No outline: a grey body with the detail in full strength. |
fill | 1,435 | Solid, with the detail knocked back out of the shape. |
stroke is the drawing every other style starts from, and since 1.0.0 every
name comes in all four. two-tone is what duotone meant until 0.9.0: the
outline kept, a 40% plate under it. duotone now drops the outline and decides
per icon which part is grey and which is black, so the thing that matters reads
first: the check on a badge, the liquid in a flask, the data rather than the
chart's axes. A glyph with nothing to fill, like bar-chart, carries its stroke
drawing in the filled styles, so no import ever comes up empty.
Rounded and sharp
Every drawing in the table comes twice: rounded, with round caps and filleted corners, and sharp, with butt caps and square corners. Same names, same coverage, so 11,480 SVGs in total.
Sharp is a drawing of its own rather than a filter over the rounded one. Squaring
a corner moves the ink, and where that changes the silhouette the geometry was
solved again, so both treatments sit side by side in raw/ and the build
converts neither into the other.
Using them
Copy one from the site. keylineicons.com is the
browser: click any icon to open it, then take it as SVG, JSX, a React import or
an npx line, at whatever style, corners, stroke width and size you have set.
The panel keeps the last three icons you opened, so two candidates can be held
side by side. That is the fastest path and needs no install.
Take the files. icons/<style>/<name>.svg and
icons/sharp/<style>/<name>.svg are plain, normalised SVGs with no wrapper, no
ids and no classes. They are generated, so treat them as build output: to
change one, change the drawing in raw/ and rebuild.
Import them in React. @keyline-icons/react exports one component per
icon, one entry point per style and corner treatment:
Every component takes the usual SVGProps plus size, and colours from
currentColor. There is no theme, no context and no provider.
The style entry points are smaller than the stroke one and deliberately so.
Check is three open strokes with nothing to fill, so it exists in
@keyline-icons/react and /sharp and in none of the others; Folder has an
interior and exists in all six. The counts at the top of this file are the same
fact.
components/icons/index.tsx is the same set generated for this repo's own
site, and @/components/icons is the import to use inside it. Both come off
icons/stroke/, so they hold the same drawings; the package is the one to
install anywhere else.
Import them in React Native. @keyline-icons/react-native is the same
components drawn through react-native-svg, with the same entry points and
export names, so shared code changes the package name and nothing else. It
works in Expo, on the web through Expo too.
A native view has no CSS to inherit from, so colour is a color prop rather
than currentColor.
Own the source with the shadcn CLI. The registry is served by the site, so
adding the set to a project is one entry in components.json:
Each icon arrives as a self-contained component that imports nothing from the package, so it can be renamed, edited or folded into the project's own conventions. Take the package to have the whole set behind one import; take the registry to own a handful of files.
Add one at a time from the terminal. @keyline-icons/cli searches the set
and writes SVGs into a project without adding a dependency to it:
Give an agent the set. @keyline-icons/mcp is an MCP server that searches
the set, returns SVG source in any style and corner treatment, and returns the
React import, so an assistant picks a real icon name rather than guessing one:
Anything else that speaks MCP over stdio runs the same command; the package's own README has the JSON.
Use them outside React. The whole set is on
Iconify as keyline-icons,
which covers Vue, Svelte, Solid, web components and the Tailwind plugin. Stroke
is the bare name and everything else is a suffix on it:
Iconify re-imports from this repository, so it carries whatever the last release drew. The install page has the snippet for each framework.
Drop one onto a Figma canvas. The Figma plugin inserts any icon in any style and either corner treatment into the file you already have open, and the Community file is the whole set as components, with style, corners and container as variant properties.
Containers
61 icons come in a square- form and 66 in a circle- form, which wrap the
base drawing rather than replacing it:
A square- or circle- prefix does not always mean a container. circle-half
and square-dashed are shapes in their own right, with no base for them to
contain, so they are filed as regular icons. The rule is that the base has to
exist before the prefix means anything.

Layout
Working on it
Node 20.9 or newer, and pnpm.
pipeline/README.md is the real documentation: what the build normalises, every
rule the linter enforces and why, how the Figma check works, and the standard a
new drawing has to meet. Read it before adding an icon. The drawing standard is
not a matter of taste here, it is measured, and the linter will tell you the
number it wanted.
Two checks deliberately sit outside CI. icons:figma needs the Figma file,
which CI does not have. brand:check rasterises through headless Chrome, where
two versions disagree by a pixel on identical input, and a check that cries wolf
gets switched off. Run both locally.
Sponsors
Preline, since August 2026.
The set is free, has no paid tier, and is not getting one. Sponsorship pays for the hours rather than unlocking anything, so every icon added is added for everyone.
Sponsoring on GitHub from $25 a
month puts your name in this section, and from $100 a month on
keylineicons.com as well. lib/sponsors.ts is the
list both read from.
