Careful software
for the careful few.

Sentryline Labs is an independent studio building quiet, durable tools for people who read their own bookmarks. We ship slowly, on purpose. Our first product is Sorturls — a calm home for the links you save.

01 — Flagship

A calm home for the links
you actually read.

Sorturls is the read-later app for people who never quite caught up. We built it for ourselves first.

SHIPPING v 1.4.2 macOS · iOS · Web

Sorturls.

Drop a link, anywhere. Sorturls captures the page, transcribes the video, summarizes the thread, and files it next to everything else you saved on the topic — quietly, without notifications, without a feed.

  • 01Capture anywhere. Share sheet, browser extension, email, paste.
  • 02Read it once. Reader view, transcripts, and AI summaries.
  • 03Find it later. Local-first search with collections and tags.
  • 04Yours, end-to-end. Encrypted sync. Export at any time.

02 — Principles

A few rules we keep coming back to.

A studio is the sum of what it refuses. These are the lines we don't cross — the sentry lines.

P / 01

Make it quiet.

No streaks. No popups. No "engagement." Software shouldn't perform for you — it should disappear behind the work.

P / 02

Ship the boring parts.

Backup, export, keyboard nav, undo. The features no one demos. We finish them before we add anything new.

P / 03

Own your bytes.

Local-first by default. Encrypted sync where useful. One button to take everything with you, in formats we didn't invent.

P / 04

Stay independent.

No investors. No growth targets. We charge a fair price, answer our own email, and let the work decide the pace.

04 — Studio

Built quietly,
shipped patiently.

Sentryline Labs began in late 2024. We had been writing software for other people for a long time, and we wanted to write some for ourselves — the kind that lasts longer than the company that ships it.

We work in the open when it helps, and quietly when it doesn't. We don't raise capital. We don't keep a press kit. We have a sentry line — a quiet boundary between the work and everything that would rather we made something else.

Sorturls is what's on our bench right now. There are two more things on the shelves behind it. They will arrive when they're ready.
