Hacktoberfest encourages participation in the open source community, which grows bigger every year. Complete the 2021 challenge and earn a limited edition T-shirt.

Every year in October we celebrate Hacktoberfest which is an open-source celebration for our global community. This fest is open to everyone worldwide whether you're a student starting to learn code, developers, event host, or even a company of any size. Hacktoberfest is gaining popularity every year and in 2020 around the first 70,000 participants were eligible to get the limited-edition T-shirt and cool stickers. This fest is playing a vital role in generating awareness and helping to drive the growth of open-source contributions for an ever-growing community. People from all backgrounds and skill levels are encouraged to complete the challenge.
