delune

We build our own software products.

Delune is a software development company. We design, build and run every product in-house: a quoting tool, a booking calendar, a challenge game and an API for dangerous goods.

Products

Four products, each with its own site and its own users. All four are live.

Quoting tool

Costimate

An online quote maker for freelancers, small businesses and tradespeople. Describe the job in plain words, get an itemised draft, set your rate, currency and VAT, then send a protected link your client can accept online.

  • Quotes in Hungarian, English and Slovak
  • Team estimates merged into one final quote
  • Free Starter plan, no card needed

Booking calendar

calends

Online booking for anyone who works by appointment: hairdressers, therapists, trainers, tutors and small practices. Online, phone and walk-in bookings share one calendar, so nothing is booked twice.

  • Reminder the day before, with a link to reschedule
  • Client history, notes and preferences in one place
  • Win-back messages drafted for you, sent only after you approve them

Challenge game

taperlit

A closed 18+ challenge game for couples and solo players. A new challenge arrives every day; players take it on, upload photo or video proof, and the community scores it.

  • Age-verified players only
  • Location data removed from every upload
  • Free to play, with no ads

Dangerous goods API

HazCard

A JSON API for dangerous goods. Send the numbers from an orange hazard plate and get back the UN number, the ADR classification and the full emergency response card.

  • 2,095 UN numbers and 250 response cards
  • Card text in 19 languages, as published
  • Plain HTTP and JSON, no SDK needed

Built in-house, from start to finish.

Every product is designed, written and run by Delune. Decisions are made by the people who write the code and answer for it after launch.

The whole product, not one layer

We write the API, the interface and the admin tools behind each product. Nothing is outsourced, so nothing gets lost in a handover.

More than one language from the start

Costimate quotes in three languages and HazCard answers in nineteen. Languages are planned in from the first screen, not added at the end.

Still here after launch

We host, monitor and keep improving what we ship. When something breaks, the people who wrote it fix it.

Write to us.

Questions about a product, a partnership idea or feedback: a few sentences are enough. Every email is answered by the people who build the products, not by a form.
