What I'm building

macOS · Developer tool

Pekivo

Copy a request, a log or a screenshot and press ⌥Space. Pekivo turns it into something you can read, filter and copy — logs, cURL, JSON, JWT, SQL and offline OCR, all on your Mac.

From $19 · Pay once · macOS 14+
macOS · Developer workspace

Avyron

Every tool, one workspace. Paste JSON, JWTs, cURL, OpenAPI, logs or diffs and it opens the right tool — plus generators, regex, hashing, .env and more. 16 tools, all running locally.

macOS · Menu bar utility

ShotFlow

Screenshots, in their place. Capture an idea, give it a name and save it straight to the right project folder — or let Quick Capture do it for you.

Two apps, two jobs

Pekivo or Avyron?

Pekivo is for looking.

You just copied something — press ⌥Space over any app, see what’s inside, close it. Like Quick Look for your clipboard.

Avyron is for working.

Open it when you need to generate, diff, hash, test a regex or clean up a .env — a toolbox window you keep open.

Reading something? Pekivo. Making or changing something? Avyron. Many people use both — they don’t clash.

About me

Hi, I'm Quan Nguyen.

I'm a software engineer who builds small, focused apps — native, fast and private by default. Pekivo started as a tool I wanted for my own day-to-day work.
