Products

We build what we need ourselves.

Each of our products grew out of a gap we saw ourselves, and we use them in our own work wherever they fit. That is our standard: we would not sell anything we would not want to use ourselves. The products have their own sites with every detail; this is what they are for.

Early access

Terminaro

Online appointment booking for the self-employed and small businesses. Customers book in seconds without an account, and the public booking page sets no cookies. Calendar sync with Google, iCloud, or CalDAV prevents double bookings, confirmations and reminders go out automatically, and booking data stays on servers in Germany.

Coming soon

Palamedes+

Managed translations for teams that use our open core Palamedes. The core stays open source; maintaining catalogs, approvals, and AI-assisted suggestions become a service. Born from internationalizing large codebases where translations should roll out in seconds rather than weeks.

In preparation

Third product

A third product is in the works. We will announce it once it runs in our own daily work and we know it keeps what it promises. Until then: Palamedes, the open core, is here today.

How we build products

Small, lasting, inspectable.

Three principles decide what we build and how. They are the same principles that guide our consulting work, applied to our own products.

Born from gaps we saw

Every product started as a gap we saw: appointment booking that asks nothing of the people who book, a translation workflow for the codebases we internationalize. Using what we build is the fastest way to notice what is still missing.

Built to keep working

A product that works for its first customers should still work for them in three years. We prefer boring, well-understood technology, keep the scope small, and change things only when we can explain why.

Open where it matters

Where a product grows out of an open core, the core stays open. Palamedes is and remains open source; Palamedes+ adds the service around it. You can inspect what you rely on.

Contact

Let's talk about what is meant to last.

For products and partnerships, an email is enough. Project support is at Sebastian Consulting, directly with the two founders.
