MUX0 Source-Available License
Copyright (c) 2026 10xChengTu
All rights reserved.
This source code is published for transparency, auditability, and personal
reading. It is NOT open-source software as defined by the Open Source
Initiative (https://opensource.org/osd). No rights are granted under this
document except those narrowly enumerated below.
1. PERMITTED USES
Subject to full and ongoing compliance with every term of this license,
and only so long as you do not engage in any Prohibited Use (Section 2),
the following are permitted without additional permission:
(a) Viewing and reading the source code in this repository.
(b) Downloading and installing official pre-built binary releases of
MUX0 published by the copyright holder and running them on hardware
you own, lease, or otherwise control — including:
(i) personal use;
(ii) use inside any organization (including for-profit
companies), by employees or contractors, on that
organization's devices or on personal devices used for
that organization's work;
(iii) use of MUX0 as a tool to design, build, test, debug,
deploy, operate, or support other software, services, or
content — including commercial, revenue-generating, or
client-facing work. Nothing produced inside MUX0 (code,
documents, command output, transcripts, etc.) is subject
to this license; you own whatever you create with it.
(c) Compiling the source code locally, on a machine you own or
control, solely for your own or your organization's internal use
as described in (b), provided the resulting binary is not
redistributed, published, hosted as a service, bundled into any
product, or otherwise made accessible to anyone outside your
organization.
(d) Creating a personal fork of this repository on a public
code-hosting platform (e.g., GitHub), preparing modifications to
the source code on that fork, and proposing those modifications
back to the copyright holder via pull request or equivalent
contribution channel. Contributions so submitted are governed by
Section 9 (Contributions). A fork made under this subsection:
(i) must not be promoted, marketed, or distributed as an
alternative, replacement, or competing version of MUX0;
(ii) must not be used to publish or distribute compiled
binaries to anyone other than the fork owner;
(iii) must retain a clear reference to this upstream
repository and its LICENSE file, unmodified;
(iv) must not be renamed or rebranded in a way that would
confuse users about its relationship to MUX0.
A fork kept up for ongoing contribution is fine; a fork kept up
as a parallel distribution is not.
In short: using MUX0 as a terminal to do your work — personal or
commercial — is fine. Forking to contribute back is fine. What is not
fine is redistributing, repackaging, reselling, or maintaining a
competing distribution of MUX0 itself. See Section 2.
2. PROHIBITED USES
Except with the prior, specific, written permission of the copyright
holder, you MAY NOT:
(a) Copy, reproduce, mirror, or republish the source code, in whole or
in part, in any form or medium, whether verbatim or modified,
except as expressly permitted by Section 1(d) (forks for
contribution).
(b) Maintain any fork, mirror, or derivative repository for purposes
other than proposing contributions back to the upstream project
— including, without limitation, maintaining a long-running
divergent fork, a competing distribution, a rebrand, or a
hard-fork project.
(c) Create, prepare, distribute, sublicense, or publish any derivative
work, adaptation, port, translation, or modification of the source
code or binaries to any third party, whether free of charge or
for a fee. (Preparing modifications on a personal contribution
fork for the purpose of submitting a pull request is permitted
under Section 1(d) and is not considered distribution.)
(d) Redistribute MUX0 itself (source or binary) to third parties in
any form — including, without limitation:
(i) reselling, sublicensing, renting, leasing, or lending
MUX0;
(ii) bundling MUX0 into a product, service, device, or
distribution that you ship, sell, license, or otherwise
make available to third parties;
(iii) hosting MUX0 (or any service whose primary value derives
from MUX0) as a Software-as-a-Service or other managed
offering available to users outside your organization;
(iv) publishing compiled builds of MUX0 on any third-party
distribution channel (app store, package manager,
website, mirror, etc.) other than the copyright holder's
own official channels.
This clause is the reason this license exists: MUX0 is free to
*use* commercially, but not free to *redistribute* or *productize*.
(e) Remove, alter, or obscure any copyright, trademark, author,
attribution, or proprietary notice contained in the source code
or binaries.
(f) Use the name "MUX0", the MUX0 logo, or any confusingly similar
name or mark to identify, promote, or market any product,
service, fork, or derivative work.
(g) Train, fine-tune, evaluate, benchmark, or condition any
machine-learning model, dataset, or AI system on the source code
(in whole or in part), or publish any dataset derived from the
source code for such purposes, without prior written permission.
3. NO TRANSFER OF OWNERSHIP
All right, title, and interest in and to the source code and binaries,
including all intellectual property rights, remain exclusively with
the copyright holder. Nothing in this license transfers or assigns
any ownership interest to you.
4. THIRD-PARTY COMPONENTS
This project depends on third-party libraries (including, without
limitation, ghostty and Sparkle), each of which is distributed under
its own respective license. Those components remain governed by their
original licenses, which are not superseded by this document.
5. TERMINATION
Any breach of Section 1 or Section 2 automatically and immediately
terminates all rights granted to you under this license, without
notice. Upon termination you must cease all use of the source code
and binaries, delete all local copies, and destroy any materials
derived from them.
6. NO WARRANTY
THE SOURCE CODE AND BINARIES ARE PROVIDED "AS IS", WITHOUT WARRANTY
OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
TITLE, AND NON-INFRINGEMENT.
7. LIMITATION OF LIABILITY
IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM,
DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT,
OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOURCE
CODE OR BINARIES OR THE USE OR OTHER DEALINGS IN THEM.
8. GOVERNING LAW
This license is governed by the laws of the jurisdiction of the
copyright holder's primary residence, without regard to its conflict
of law provisions.
9. CONTRIBUTIONS
By submitting any contribution (pull request, patch, issue comment
containing code, or equivalent) to this project, you:
(a) Represent that the contribution is your original work, or that
you otherwise have the right to submit it under the terms of
this license;
(b) Irrevocably grant the copyright holder a perpetual, worldwide,
royalty-free, non-exclusive license to use, reproduce, modify,
relicense, sublicense, and distribute your contribution as part
of MUX0 under this license or any future license the copyright
holder chooses to adopt for MUX0;
(c) Understand that your contribution, once merged, is subject to
the same terms as the rest of MUX0 — in particular, you do not
retain the right to redistribute a version of MUX0 containing
your contribution outside the terms of this license.
For inquiries about redistribution, bundling, hosting as a service,
maintaining a non-contribution fork, or any other use not permitted
above, contact the copyright holder.
