Kelkun is a service platform that connects individuals with qualified local professionals for home repairs, maintenance, renovations, and other projects. Customers describe what they need, and Kelkun searches for available tradespeople; users can then compare quotes and choose a professional. The service covers more than 80 trades, including plumbing, electrical work, heating, locksmithing, painting, masonry, and tiling, with support for urgent callouts as well as scheduled work.

Kelkun aims to make finding and managing a professional simpler, from submitting a request through following the work. Customers can use the mobile app or web platform to share project details and photos, receive notifications, manage appointments, and communicate with providers. The site states that listed professionals are verified and insured, and promotes free quote requests, secure payment at the end of an intervention, and legal protection for eligible emergencies and repairs, with coverage up to €10,000.

For tradespeople, Kelkun provides a professional workspace with qualified customer requests, quote and appointment management, a calendar, and client messaging.
