Independent software studio

We build the software, then we publish it here.

Tools we wanted to exist, released directly to the people who use them, with a changelog you can actually read.

HangLine for desktop

The first thing we shipped, and still the one we use every day. HangLine hangs your tasks from a thread at the top of your screen. Free to use, with a free account. Pro is optional.

Marketing toolFree to start

HangLine for websites

Built for marketers. An offer, a product or a question hangs on a real thread over your website and opens a card when clicked: a link, WhatsApp, a form, a survey. Every step is counted, from the visitor who saw it to the lead or order, and goes to your Meta, TikTok, Snapchat, LinkedIn, Pinterest and Google ads.

How we work

We bring our ideas alive, then give them away.

An idea gets built the week we have it. We use it ourselves until it earns its place, and then we publish it here for free.

01

The idea. Something we wish existed, sketched in an afternoon.

02

The build. In-house, start to finish, no outside brief.

03

The release. Published free, with a changelog written by hand.
