Hacktoberfest 2026 wrapped up on October 31st! Thank you to everyone who built, hosted, mentored, judged, and tuned into Hacktoberfest this month. 🎉
This year, we focused on building with open-weight models and open source AI, at Fests around the world and online. Our hope was to bring the community together and WOW, so many of you showed up!
🎃 Hacktoberfest by the numbers
- 115,385 people took part, at in-person Fests and online, from Global Hack Week to DEV Challenges
- 500+ in-person Fests in 70+ countries and territories (our original goal was 300!)
- 50+ livestreams from the community, partners, and Global Hack Week programming
🏆 Meet the DEV Challenge winners
We ran five challenges this month, with one prompt and a new theme each time. Go say congrats to the winners and see what they built:
Week 4: Ghost in the Machine winners will be announced late this week!

Yo Noah posting on the DEV team org??? Good stuff XD
Hope everyone had a good hacktoberfest! I wrote an article about my first time experience on this event and some feedback on it too! dev.to/francistrdev/this-is-my-fir...
If anyone is interested, feel free to share your sticker book here or in that article I linked! Would love to hear your guys' experience :D
Also, Completionist++!!!
There were pros and cons, but considering everything, I feel like this was the most eventful Hacktoberfest ever!
The most significant achievement I gained from this Hachtoberfest is the following project I've built. God willing, I'm certainly going to do a lot of work on this, as I myself will use it for sure: 🥰
Hacktoberfest Open-Source AI Challenge: Ghost in the Machine Submission 👻🌼
From a Simple "Mark as Seen" to Feedgrab & Ghostify: Story of My Life!
I didn't really fight for the stickers, so here's what came naturally 🥰
Huge thanks to all the organizers and partners 🥰
