Introduction
DevFest Kolkata 2026, the flagship annual tech conference hosted by Google Developer Group (GDG) Kolkata, takes place on Sunday 22 November 2026 at The Westin Kolkata Rajarhat, running 7:30 AM to 6:00 PM. It is a full day of hands-on workshops and expert talks on AI, cloud, mobile and web technologies, with a separate workshop day the day before.
Tickets have moved fast. The Early Bird allocation sold out in two minutes, according to the GDG Kolkata community page, and later phases have sold through in turn. All tickets are now sold out on KonfHub, including the Early Bird, Regular and Exclusive tiers and the Workshop Day ticket.
Event Overview
DevFest Kolkata is part of the global DevFest series run by Google Developer Groups around the world, and it is GDG Kolkata's biggest event of the year. The conference brings together developers, startups and creators from across the region, built around knowledge exchange, hands-on learning and networking within Kolkata's growing tech ecosystem.
The weekend starts a day early. Pre DevFest Kolkata, billed as Builder's Day, runs on Saturday 21 November 2026, 10:00 AM to 4:00 PM, at Sister Nivedita University, with a separate workshop ticket at 299 INR. The main conference follows on Sunday at the Westin in New Town.
What to Expect
A long day, starting early. Doors open for a 7:30 AM start, and the programme runs through to 6:00 PM. The published themes cover AI, Gemini and Gemini Enterprise, the Agent Platform, Android, Firebase, Flutter, Google Cloud and Web, alongside community building, networking and hands-on workshops.
The workshop day on 21 November is the hands-on part of the weekend: a day of building at Sister Nivedita University before the main conference. Ticket tiers differ between the two days, and the organisers advise choosing carefully, since different tickets carry different benefits.
The 7:30 AM start makes this one of the longest DevFest days in the country: ten and a half hours from doors to close. Attendees should plan for a full day, with the workshop day on Saturday as a separate commitment for those who want the hands-on sessions as well.
Who Should Attend
Developers, students, startup teams and creators. GDG Kolkata describes its community as technology-driven, bringing developers, entrepreneurs, working professionals and students together to learn, teach and share. The conference is designed for that mix: talks for people who want the latest on AI and Google technologies, workshops for people who want to build with them, and networking for everyone.
Students get a day inside one of the city's bigger tech gatherings. Working developers get sessions on the tools they use daily, from Android and Flutter to Firebase and Google Cloud. Founders and startup teams get a room full of builders and the wider Kolkata tech community.

Venue and Location
The main conference takes place at The Westin Kolkata Rajarhat, Plot No. 2, AA II, Newtown, Kolkata, West Bengal 700156. The hotel is in New Town, Kolkata's planned IT and business district, close to Sector V and the airport corridor. It is reachable by bus, taxi and app cab from across the city.
The workshop day is at Sister Nivedita University, also in New Town, Kolkata 700156.
Why This Event Matters
Kolkata's developer community has grown steadily, and DevFest is its flagship date. The speed at which tickets sold, with the Early Bird gone in two minutes, says more about demand than any description could. A full-day conference at a major New Town hotel, with a workshop day attached, puts Kolkata's DevFest on the same footing as the bigger city editions.
For developers in eastern India, it is also a matter of geography. Kolkata is the natural hub for the region, and a conference of this scale means developers from West Bengal and neighbouring states can attend a major Google developer event without travelling west.
