On the behalf of ZDF, one of the series' co-producers, with the intention of renewing Heidi, Girl of the Alps and fellow series to the modern children's audience, the series was produced from 2013 to 2014, mainly in France, that much like Maya the Bee and Vicky the Viking before, including being done by the same main studio, on the behalf of ZDF, but in this production, multiple other companies, including the Australia-based, specifically-made Heidi Pyl, joined in on making the series.

In the first production, from the writing bible, written by Christel Gonnard, was the first twenty-seven episodes first had their locations shot with high-definition footage, for reference to the animators making the now-fictionalized locations of the series, in Haute-Savoie for the Alps (referred to as that, rather than the Alm, as in the base series and novel) and in Friborg for Frankfurt, similarly to Zuyio (later Nippon)'s team shooting pictures of the official locations themselves, for the setting references to background painters and writers, for the base series. The two halves that happened to be made in that production were directed, respectively, by Pierre-Antoine Hiroz and Anne Deluz. The theme music was two songs at the time; the credits song, replaced by a bit of a piece of background music from the series, when the series was bought the rights out of, was sung by Cindy Santos, first known in 2006, when she participated in the French show Nouvelle Star.

The first three episodes were screen as a "world preview" at Geneva's Tout Ecran Movie Festival (Festival Cinéma Tout Ecran) on October 31, 2007 (albeit only coincidentally for Halloween). Later, was a twenty-episode documentary series, of three minutes each episode, and produced by Rita and Chocolat TV Productions, aired on Télévision Suisse Romande as well as on Chocolat's website, before the latter was removed, which documented the first production. Afterwards, an account of a promoter, impersonating an now-teenage Heidi, was opened on a blog and a MySpace page, where the character promoted the series. The series premiered on the Swiss network Télévision Suisse Romande on December 22, 2007, in Swiss HD. In France, Studio 100 Animation bought the rights in 2013 and produced a 3D series of 39 episodes of 26 minutes each, now directed by Jérôme Mouscadet, from that year to 2014 and the completed series began airing in 2015.

Due to the partnership of Eurovision Fiction, was the series sent to their affiliated countries, including Ireland, Norway (see below), Cyprus (in Greek dub), Slovakia (also see below), Bulgaria and Poland and aired (as of recent, at least part-finished) on the EBU member chains of those countries.

A second season with 26 episodes was soon made.
