Building software that will always be there for our users
When choosing software that will be core to how one’s organization operates, such as a team chat platform, there is an important question: “Will this product still exist and be responsibly maintained in a few years?”
We have designed our governance, community, and technology with the explicit goal of Zulip being actively developed for many years to come. This theme cuts across many of the decisions described below. It is also reflected in our history: Zulip's earliest customers have enjoyed uninterrupted service since 2013.
We’re building software that is easy to maintain, so it does not require a large team to keep the lights on. We have consistently emphasized high standards for codebase readability, code review, commit discipline, debuggability, automated testing, tooling, documentation, and all the other subtle details that together determine whether software is easy to understand, operate, and modify.
Commitment to the mission
Zulip is stewarded by the Zulip Foundation, with a mission of developing the best possible team chat experience, with a particular focus on public-interest organizations and communities. The Zulip Foundation fully owns Kandra Labs, the company responsible for hosting, supporting, and improving Zulip for use across all industries.
This structure, announced in May 2026, formalizes our longtime commitment to Zulip’s sustainability and independence. It allows us to fairly compensate a talented, dedicated team of core developers, without taking outside investment that could put pressure on us to compromise our values.
Doing right by our users
We’re fully committed to being a trustworthy, transparent vendor for our customers. Kandra Labs has been public about its values for years — including our commitments to protecting customer data privacy, and to keeping our focus on the product, not on whatever’s commercially fashionable.
Keeping Zulip 100% open source
Many modern “open-source” companies use a version of their product with some basic functionality intentionally removed as a demo for their non-open-source paid product. In contrast, we are committed to keeping Zulip 100% open source.
When you self-host Zulip, you get all the features of our cloud offering. We work hard to make it easy to set up and run a self-hosted Zulip installation without paying us a dime, which is why thousands of organizations do so.
Investing in community and mentorship
Zulip is developed by a vibrant open-source community, and we are fully committed to helping bring up the next generation of open-source contributors from a wide range of backgrounds.
We have invested into making Zulip’s code uniquely readable, well tested, and easy to modify. Beyond that, we have written an extraordinary 185K words of documentation on how to contribute to Zulip, with topics ranging from practical Git tips to essays on important architectural decisions.
We also welcome and support contributors via formal internship programs, with over 100 participants since 2016. Because of the thousands of hours our more senior contributors (including alumni of these programs!) have dedicated to mentorship, many of these participants have told us that they learned more contributing to Zulip than in their 4-year formal computer science education.
Supporting other worthy organizations
An important part of Zulip’s mission is ensuring that worthy organizations, from programming-language developers to research communities, are able to use Zulip whether or not they have funding.
We sponsor Zulip Cloud Standard hosting for open-source projects, research groups, education, non-profits and other communities. This program has grown exponentially since its inception; today we are proud to fully sponsor Zulip hosting for hundreds of organizations.
