Apps

Many tools. One suite.

.txt · .log · .conf

Text Editor

A minimal plain-text editor. Open, edit, save. No language modes, no syntax highlighting.

krill-text-editor→ .md

Markdown Editor

Typography-first markdown editor with muted syntax, on-demand preview, and KaTeX + Mermaid in the render pane.

krill-markdown-editor→ .csv

CSV Editor

Spreadsheet-shaped grid for comma-separated files. Virtualized rendering, Excel-keyed editing, RFC-4180 parsing.

krill-csv-editor→ .pdf

Document Viewer

A PDF reader with lazy page rendering, real text selection, and a thumbnail sidebar. PDF.js under the hood.

krill-document-viewer→ .opml

RSS Reader

Three-column reader for OPML feed lists. Local sync, no accounts, no daemon. Just an OPML and a window.

krill-rss-reader→ PNG · JPEG · WebP · BMP · TIFF · GIF · ICO

Image Editor

Crop, rotate, flip, resize, brightness, contrast, saturation, filters. Bake to any common raster format.

krill-image-editor→ any image

Image Viewer

Open an image. Zoom, pan, fullscreen. No filters, no metadata panel, no thumbnails.

krill-image-viewer→ any file

File Drop

Pair with a friend via a shared code, then drop a file. End-to-end encrypted, peer-to-peer over iroh QUIC, no accounts.

krill-file-drop→ CPU · mem · disk · docker · GPU

System Monitor

A glanceable system-load hint. One tab per resource — CPU, memory, storage drill-down, Docker images, GPU. No process table, no graphs wall.

krill-system-monitor→ .wav

Audio Editor

Open or record a WAV. Drag to select, cut / trim / silence, save. Recording is a verb inside the editor — no separate recorder app.

krill-audio-editor→ .png

Paint

Open a blank canvas and draw. Brush, lines, rectangles, ellipses, flood fill, eyedropper, undo. One bitmap, no layers. Save as PNG.

krill-paint→

Krill principles

A simple interface.

Focus One app, one job. One file, one window. No tabs, no project trees, no mode pickers — the work in front of you is the work.

Beauty A locked palette, careful typography, chrome that sits still. The apps shouldn't be the part of your desktop you have to forgive.

Simplicity No settings panel, no plugin system, no power-user knobs. If a feature can't be explained in a sentence, it doesn't ship.

Ownership Your files on your disk in their original format. No accounts, no cloud, no telemetry. MIT licensed; build it yourself if you don't trust ours.

Install

One line, any app.

The same install script works for every krill app. Pass the repository name as the argument; it fetches the latest .deb from GitHub Releases and registers it via apt so it survives system upgrades.

Prefer AppImages? Download from each app's releases page and the in-app updater handles the rest via Help → Check for updates…
