Verify every keycap before you pull: true-scale solver for mechanical keyboard enthusiasts
Download Nonta AfavostSelect the tool that matches your workflow: real-time fit checking, color palette sampling, or step-by-step swap planning with illustrated procedures
All tools included in single download. Works fully offline with no account required. Suitable for enthusiasts working with 65% layouts and custom keycap sets.
The solver starts with your board specifications: layout percentage, sculpt profile, stem mount type, stabiliser bar configuration, front height, and typing angle. Each parameter affects which keycaps physically fit each position on your matrix.
Select the kits you own from your keycap set—base, novelty, spacebar, numpad, ISO—and the solver instantly recalculates coverage across every position. The plate matrix updates in real time, showing covered slots in one shade, safe substitutions within height tolerance in another, and missing keys highlighted for immediate visibility.
Once validated, export a colored fit sheet showing your final colourway applied to the true-scale plate. Switch to the Bench tab to generate a procedural swap plan: pull alphas row-first, check stabiliser wires for dust, read stems under short keys, then lay pulled caps in sequence for error-free reinstallation.
Define layout percentage, sculpt profile, stem mount, stabiliser bar type, front height, and typing angle. Every parameter feeds into the compatibility algorithm that determines which caps physically fit each matrix position.
View your keyboard at true unit scale—6.25u spacebars, stepped Caps Lock, and two-row Enter keys render at actual relative widths. Tap any key to inspect which caps serve that slot and allot one of eight sculpted artisan positions.
Photograph your physical keycap set and drop up to five color sampling reticles directly on the image. Lock in alphas, modifiers, accents, novelty, and legend ink, then apply the sampled palette to the entire plate matrix for accurate visual preview.
See instant counts for covered keys, safe substitutions within height tolerance, and keys you are short on. The metrics panel updates in real time as you toggle kits, giving you immediate feedback on whether your set fully covers your board.
Generate a procedural swap plan with illustrated tool references. Pull alphas row-first, remove mods and bars, check stabiliser wires for debris, read stems under short keys, then lay pulled caps in sequence. Check off each step as you go—progress persists between sessions.
Export a complete fit sheet showing your sampled colourway applied to the true-scale plate matrix. Use the exported sheet as a reference during installation or share with other enthusiasts to verify kit compatibility before purchasing.
