LeanBytes

Native apps that take the repetitive work off your hands.

LeanBytes makes tools for people who spend their whole day at a computer — and for the AI agents now working the same files. Genuinely useful software that disappears into the work instead of competing with it.

What we make

FrameBison

Early Access
Early access means development is still running. It also means the app can only get better if you say what is missing or what is broken — that feedback is the roadmap. And the video is no mockup: it shows exactly what you get today.

Marketing assets for your app.

Build your frames, arrange screenshots and text until it looks right, and export what the launch needs: App Store screenshots, one localized set per language, X and LinkedIn headers, images for directories and communities.

One-time purchase, no subscription.

FileFillet

Organize files. Quickly.

Copy or move files and folders straight to your favourite folders — and their sub-folders — without opening another Finder window.

TailBeat

Native log viewer for Apple developers.

Search, filter and inspect millions of log entries in real time in a fast, native interface. Through MCP, your AI coding assistant gets the same view of your app's runtime behaviour — so it can verify its changes with evidence instead of guesswork.

FlowMoose

Do more with your voice.

Speak into any text field and the words land where the cursor is. Record what your Mac is playing too — a video, a call, an online meeting — and get it back as text you can work with.

Pandalytics

Know the same day, not two weeks later.

Sales dip in one market because of a tiny bug? Pandalytics catches it the same day: it correlates behaviour instead of counting events, spots anomalies against your app's own baseline with nothing to configure, and stores no IPs, device IDs or cookies — an installation hash that cannot be traced back to a person.

Native web appIn development

Early access as soon as there is something to try. How your address is handled.

Three rules we do not bend.

01

Native, never wrapped

We build on each platform's own frameworks. Instant launch, no runtime tax, and behaviour that matches the system it runs on.

02

Local by default

Your files stay on your machine. Nothing is uploaded unless sending it is the whole point of the feature — and then you decide.

03

Built for two kinds of user

A person and an agent will both drive these tools. Anything you can click, a script or a model can call — same rules, same result.

Release notes, not marketing.

A short note when something ships or opens up for testing. No more than once a month, unsubscribe in one click.

One email a month at most. How your address is handled.

Something on your machine that should be quieter, faster, or automatic?

The shipping apps take requests, and Pandalytics is early enough to shape.
