Isocons
Free isometric SVG icon set, three perspectives, CC BY 4.0
Tier B · UsefulIcon Setisocons.app
An isometric icon library drawn in three perspectives and two corner styles, exported as SVG with stroke weight and colour editable on the site before download. It ships as a Figma plugin as well as direct download, and is free under CC BY 4.0 with attribution. Note: the site is a client-rendered Next.js app that serves an empty shell to fetchers, so the counts below come from third-party listings rather than first-hand reading.
For an agent
Reach for this only when the design deliberately wants isometric/2.5D iconography — feature grids, developer-tool marketing pages, infographic decks — never as a general UI icon set, where Lucide or Phosphor are the right call because they align to a pixel grid at 16-24px. Isometric glyphs lose legibility below roughly 32px, so budget space for them. Two practical warnings: the licence is CC BY, not MIT or CC0, so the project needs a visible credit line; and you cannot enumerate or scrape the catalogue programmatically because the page renders entirely client-side (its robots.txt still points at a placeholder acme.com sitemap), so a human has to pick icons in the browser or via the Figma plugin.
Why it is here. A rare free isometric set that is consistent enough to use as a system rather than as one-off spot art, though the CC BY attribution requirement and the unscrapeable site limit it.
