How do I request sponsorship or special pricing for my organization?
You can request sponsorship from an organization's
billing page, or contact us at
Zulip sponsors free Zulip Cloud Standard for hundreds of
worthy organizations via the above programs. Organizations whose members are
not employees are generally eligible for special pricing.
Does Zulip scale to a large number of users?
Yes! Some of our biggest fans have hundreds or thousands
of users, including Fortune 500 companies like Akamai,
and open source communities like
Recurse Center. If you’d like to see a large Zulip
in action, the
community server has thousands of accounts and hundreds of weekly active users, and is run on a single machine with 8GB of RAM.
Can I pay by credit card and/or invoice?
You can always use a credit card to pay, and we can bill
by invoice for amounts over $1000.
Can I start on Zulip Cloud and later move to On-Premise?
Yes! Our high quality export and import tools
on-premise) ensure you can always move
from our hosting to yours (and back). If
you’d like to do a migration, email
email@example.com and we’ll get you started!
How are guest users billed?
Guests cannot see or join streams they are not invited
to. Guests subscribed to more than 1 stream are billed
like regular users. Guests subscribed to a single stream
are generally free, unless you have more than 5 times as
many single-stream guests as paying users. More details
are available here.
How does the free plan message limit work?
Only the most recent 10,000 messages can be viewed
and searched with Zulip Free. Older messages are
still stored and will become available again
should the organization purchase a paid plan or
get Zulip Cloud Standard free because they are an
open source project or similar organization.
What is the difference between automatic and manual billing?
With automatic billing, you automatically purchase a Zulip license
for each user in your organization at the start of each billing period
(month or year). Deactivating a user frees up their license for reuse.
Additional licenses are purchased automatically as needed.
With manual billing, you choose and pay for a preset user limit. If
the limit is reached, no more users can join until licenses are manually
In general, we highly recommend selecting automatic billing unless you
have a specific reason to do otherwise.
How will I be charged for temporary users (e.g. limited-time
can be deactivated
any time. Deactivating a user frees up their license for reuse.
Who can I contact if I have further questions?
