A monospaced slab-serif with flat, square-ended serifs and terminals that create a crisp, rectilinear rhythm. Strokes are thin and even, with minimal modulation and largely circular bowls set against straight stems, producing a clean, engineered texture. Serifs are unbracketed and horizontal/vertical alignment is emphasized throughout, giving letters a structured, grid-friendly presence. Lowercase forms stay straightforward and readable, and figures are simple, open, and consistent in width for tabular alignment.
Well-suited to environments where alignment matters, such as code editors, command-line interfaces, tables, and structured forms. It also works for technical documentation, captions, and editorial sidebars where a disciplined, monospaced texture supports scanning and comparison.
The overall tone feels technical and methodical, with a lightly retro, typewriter-adjacent flavor. Its strict spacing and squared details lend an institutional, no-nonsense character that reads as precise rather than expressive.
The design appears intended to provide a monospaced, slab-serif alternative to classic typewriter and terminal faces, prioritizing consistent spacing, clear silhouettes, and a controlled, architectural feel.
Because every character occupies the same advance width, the design forms a strong vertical cadence in text blocks and makes punctuation and symbols feel intentionally placed. The squared serif treatment keeps the face looking sharp at larger sizes, while the thin strokes suggest best use where sufficient size or contrast is available.
