Google Summer of Code 2025 with Zulip - Work Product

Hey 👋, Aman here. This is a summary of all the work I did for the Zulip chat application and my personal experiences as a part of the Google Summer of Code 2025.

📋 Introduction

What is Zulip?

Zulip is an open-source group chat application built to make conversations both organized and easy to follow. While most chat tools pile everything into one fast-moving feed, Zulip takes a different approach with its topic-based threading system.

  • Streams and Topics: In Zulip, discussions are arranged within streams (similar to channels), and every message belongs to a specific topic. This structure ensures that conversations stay on track and users can quickly revisit any thread without sifting through unrelated messages.

  • Best of Both Worlds: Zulip is designed to handle both real-time conversations and asynchronous communication seamlessly. Whether a team is working together live or catching up later from different time zones, Zulip makes it easy to stay in sync.

  • Open Source with a Strong Community: As a fully open-source project, Zulip is shaped and improved by a global community of contributors. It’s widely adopted across industries—from startups and open-source projects to research institutions and large organizations.

  • Feature-Rich Collaboration Hub: Beyond messaging, Zulip offers powerful integrations, advanced search, markdown support, bots, and many other features that make it more than just a chat app—it’s a central place for collaboration.

Why Zulip? - Efficient communication with organized team chat.

Let's dive deeper into the work I did with the amazing Zulip community.

📌 Areas I Have Worked On

  • UI/UX improvements

I worked on standardizing the casing of language names in dropdowns, such as in the auto-complete menu in Settings → Code playgrounds, to ensure consistency with typeahead behavior in code blocks. I also fixed issues related to displaying the move messages count, making sure it appears correctly across different views. Additionally, I improved cursor and focus handling in the settings menus and custom forms to make the interface more intuitive for users.

  • Message and unread marker handling

I fixed bugs related to unread and move message counts in certain narrows, ensuring that the displayed counts are accurate. I also implemented logic to automatically remove unread markers for messages when a stream is archived, which eliminates the need for users to manually mark them as read. Furthermore, I worked on marking muted topic messages as read, improving consistency in how unread behavior is handled across different contexts.

  • Invites and permissions

I implemented support for editing multi-use invites, allowing users to update the invites they created. Admins were also given the ability to edit invites created by lower-role members. These edits include changing the role of the invitee, updating the channels the new users will be joined to, and setting new welcome bot messages at any point in time.

  • Keyboard shortcuts & platform-specific behavior

I refined the handling of keyboard shortcuts, specifically by special-casing the behavior of Ctrl + [ on macOS so that it remains consistent with its behavior on other operating systems. This ensures a uniform user experience across different platforms.

  • Message actions and features

I added a new “Quote and reply” icon to the message action bar, with logic that ensures the icon is visible only when the corresponding menu option is hidden, and vice versa. I also worked on improving the delete-message workflow by introducing a clearer choice between “Delete for me” and “Delete for everyone,” making the process more convenient for users.

  • Backend and database migrations

I contributed to backend changes and database migrations, including work to clear unread markers for messages in archived streams. I also fixed issues with subscription and unsubscription event handling during archival, ensuring that related events and counts are updated accurately.

✨Learning & Personal Experience with Zulip

As Google Summer of Code comes to an end, I can’t help but reflect on my one-year journey with Zulip. When I started, I was a beginner, unsure and a little afraid to dive into something so big. Fast-forward to today, I realize how much I have grown—not just as a developer, but as a person. Zulip has been at the heart of this journey, and I will always remain grateful for the welcoming community, the excellent documentation, and the incredible support from mentors and contributors.

Over this period, I learned far more than I ever expected. From writing industry-level code, crafting clear commit messages, and using git rebase to keep pull requests clean, to understanding the code review process and learning the true value of collaboration, Zulip has shaped me in ways no textbook could. I also gained confidence in Git and GitHub, skills that once felt intimidating but now feel natural. Perhaps most importantly, I learned how to review my own work critically, address feedback thoughtfully, and communicate effectively within a global developer community.

I am deeply thankful to my mentors— Sanchit Sharma, Afeefuddin —for their patience, guidance, and invaluable feedback throughout the journey and my buddy Apoorva Pendse. I also want to thank Tim Abbott for helping me prioritize work and all the maintainers especially Sahil Batra providing insightful reviews, as well as Alya Abbott, Karl Stolley and Lauryn Menard for their continuous encouragement and support.

This experience has been nothing short of transformative. GSoC with Zulip was not just about code—it was about growth, confidence, and the joy of being part of a community building something real and impactful. Thank you, Zulip, for making this summer one of the most memorable chapters of my life. 💙
