Independent · self-hosted

Software we build and run ourselves.

An independent lab. We write the tools we wanted to exist, host them on hardware we own, and hand out accounts one at a time — no growth team, no data to resell, and no service that disappears when somebody gets acquired.

6 services live · open source · run your own or use ours

01 Open services

Running in the open

Every one of these gets used by us daily before anyone else is let near it. Each has its own front door: open the one you want, ask for an account there, and a person approves it — not a form.

TabUp

live

Shared expenses for trips and flatmates. Who paid what, in any currency, and the shortest set of payments that settles it — without an app trying to sell you a card along the way.

QR-Forge showing a dynamic QR code and its destination

Print the code once and change where it points forever after. Every scan counted, by day and by country.

DocDrop's home page: three files uploading, each with its remaining life and downloads left

Send the whole 6 GB video untouched. It resumes if the connection drops, and deletes itself when you say so.

SecretDrop's home page: a password typed into the composer, before the link exists

A password that stops existing once it is read. Encrypted in your browser; whoever receives it needs no account.

Pixelforge's home page: a photo split by a draggable line, background still there on one side and gone on the other

Cut a background out, or turn a logo into a vector. Full resolution, no watermark, nothing kept afterwards.

LinkUp

live

Short links that strip the tracking and keep what the page actually needs. No visitor address is ever read.

Not everything we build is a service we run. Arveil, an end-to-end encrypted messenger for families and small circles, is open source for you to host yourself. All projects.

02 Why trust this

Your data has somewhere to be, and it stays there

We run on our own infrastructure. Not a reseller of somebody else's platform, not a startup with an exit to plan — which is why the answers below can be this short.

Privacy

Nothing to sell

No advertising trackers, no pixels, no behavioural profiles. The only measurement is privacy-first aggregate analytics — and there is no business model that would reward us for looking at what you store.

Local first

Kept close, deleted for real

Where it can be, your content is encrypted before it ever leaves your device. What you set to expire is deleted rather than archived somewhere you cannot see.

By invitation

Small on purpose

Accounts are approved one at a time by a person. We are not trying to grow this into something that needs to monetise you to survive.

Open source

Inspect what runs

The source for all six is public, and each ships a container image built from a tagged commit — scanned before release, with provenance and an SBOM. Reading the code is one use of that. Running your own copy, with no licence and no seat count, is the other.

03 How to get these

Three ways to use them

The software is free and the source is public. What changes between these three is who runs it and who answers when something breaks.

Free · today

Run your own

Pull the image, point it at your identity provider, and it is yours. No licence, no seat count, nothing held back for a paid tier.

By invitation

Use ours

Ask for an account on the service you want; a person reads the request. Good for people, not for anything a company depends on.

Commercial

Have it deployed

On infrastructure you own: installed, integrated, backed up and kept up to date — by the people who wrote it.
