KarLancer is an Iranian online freelancing and remote-work platform that connects businesses and individuals with skilled freelancers across the country. It supports both sides of project work: clients can post projects and review proposals, portfolios, and specialist profiles, while freelancers can find assignments and earn income remotely. Its services span web and graphic design, website and app development, programming, content writing, typing, translation, SEO and digital marketing, as well as animation, photography, video, and other creative work.

Projects can be submitted free of charge, and clients can compare applicants, communicate with them, and select a suitable professional. KarLancer highlights secure payments: project funds are held until the client approves the completed work, with final payment made after satisfaction. The platform also offers customer support by phone and online chat, and advertises a 2% reward for outsourcing projects. Alongside its marketplace, KarLancer provides freelancer profiles and portfolios, service listings, online training, membership plans, and skills tests.
