A comprehensive mentoring guide is available here.

Contributor’s Guide

GSoC contributor applications are open from 16 March to 31 March 2026.

The list of proposed projects is available at: Project idea’s page

Please verify your eligibility by reviewing https://summerofcode.withgoogle.com/rules/, particularly section 7.1 “GSoC Contributors”.

We encourage you to familiarise yourself with the Open Data Hub’s communication channels, shared below.

Communication Channels

Element Matrix

Join our Element Matrix channel: Element’s Matrix

Note: If you experience difficulty joining the channel, please contact us at help@opendatahub.com

Do not use Element matrix to submit your project proposals (see mailing list for that), neither as a one-on-one mean of comunication with your mentors. Please note many mentors are not on Element Matrix.

Mailing List

We have an internal mailing list that all mentors can read, use this for any kind of communication that should be private and you might not want other contributors to see. Examples:

Proposal drafts for feedback
New project ideas
Personal matters
