Glyphwright

Describe the icons you need and Glyphwright draws them on a fixed grid with one stroke weight and corner style, then checks every new icon against the existing set before adding it. You can also upload ten of your current icons and it will extend that family instead of starting a new one.

Product designers and design-system teams use it to fill gaps, such as the forty icons that were never drawn. Output is clean SVG ready for a sprite or an icon font. It handles interface metaphors well and struggles with brand-specific objects; a niche medical device or a regional landmark usually needs a few rounds of edits.
