Bragonzi began playing at the age of six with her hometown team, Montodinese. After joining the youth sector of
Inter Milan and making her debut in the "Nerazzurri" first team, in 2018 she moved to
Juventus, where she initially joined the U19 team. The following year, however, coach Rita Guarino added her to the first team: thus, Bragonzi made her debut both in
Serie A, and in
Coppa Italia, where she also scored her first goals in the black and white shirt. Despite contributing few appearances, the attacker also put her signature in the victory of two consecutive championships, a national cup and an
Italian Super Cup. In the summer of 2020, Bragonzi was sent on loan to
Verona. In a difficult Serie A season for the yellow-blue team, the presence of the center-forward, who finished the championship as the team's top scorer with six goals in 15 games, proved to be fundamental in achieving salvation. In December 2020, she was elected
European Golden Girl of the year, a football award established by
Tuttosport in 2018 and awarded every year to the best U21 player in the top flight European championship. After her experience at Verona, Bragonzi was sent on loan to
N|2021 for
Empoli in the 2021–22 season, and replaced leaving
Elisa Polli. At the disposal of coach Fabio Ulderici, she has been used since the first day of
2021-22 Serie A season, making her debut with the new shirt on 28 August in the 3–0 home defeat against
Roma. An important player in the attack, Bragonzi scored for the first time in the following match with
Pomigliano, scoring the Tuscan team's second goal from a penalty before their opponents managed to recover to make it 2-2. Her scoring abilities were later confirmed, becoming Empoli's best scorer with seven goals, thanks also to which she contributed to her team reaching 9th place, the last one that guarantees salvation. With the club's decision not to sign up for the next league season, selling Empoli to
Parma 1913, Bragonzi returned from her loan with Juventus before her transfer to
Sassuolo in the incoming 2022–23 season. The loan to Sassuolo ended at the end of 2022 with five league appearances, always moving on loan to Pomigliano in 2022 at the beginning of January 2023, with which she collected two goals in ten appearances and won the very important
promotion-relegation play-off against
Lazio, which allowed the Granata to remain in Serie A. With the start of the 2023–24 season, she returned to Juventus, only to be transferred on loan to
Sampdoria It was with the "Bianconere" that she scored her first goal with the Sampdoria shirt in the match on 16 December 2023, which ended 1-0 for the "Blucerchiate". In January 2024, she returned to Juventus. Thanks to the little space found in Max Canzi's plans, she was loaned again on 4 January 2025, this time to
Genoa in the
Serie B league. She remained there until the end of the season, before returning to the "Black and White", and terminating her contract. Following 2 August, she signed with
Trabzon, in the
top flight Turkish club. == International career ==
