License

Paddock is proprietary software that we give away. It costs nothing, there are no usage limits, and personal and commercial use are both covered. The plain-language summary below is here so you do not have to read a contract to know where you stand; the agreement itself is the legal text, and it controls wherever the two differ.

What You Can Do

Subject to the agreement, the license lets you:

  • install and run Paddock on as many machines as you own or control, for any purpose, evaluation or development or production, personal or commercial;
  • serve models with it, and build applications and services on top of it through its published APIs, its Model Context Protocol surface and the CLI. What you build that way is yours;
  • measure, benchmark and publish Paddock's performance and behaviour. That right is granted expressly, and you do not need our consent to use it;
  • pass Paddock on as a complete, unmodified official release archive with its license files, notices and attributions intact, through a mirror or a package manager. Everyone who receives a copy that way is licensed by us directly, on these same terms.

Those rights are perpetual and irrevocable for every version you have received. A later release cannot withdraw the one already on your disk.

What You Cannot Do

There are three restrictions, and they are the only ones the agreement imposes:

  • No reverse engineering. Do not disassemble or decompile the binaries or the kernel packs, or otherwise work backwards from what we ship to Paddock's source code, algorithms or kernel internals.
  • No modification or extraction. Do not modify Paddock or create derivative works of it, and do not extract, repack or reuse parts of it outside the software as distributed. The GPU kernels are the specific thing this protects.
  • Keep the notices. Do not remove, alter or obscure proprietary notices, labels or marks, including the third-party attributions.

Modified, repackaged or partial copies may not be redistributed. Where applicable law gives you a right to decompile or analyse the software that you cannot sign away, such as the interoperability rights under EU Directive 2009/24/EC, that right applies to its minimum legal extent regardless of the first restriction.

Source code is not part of the free distribution. Where we provide source code or other non-public material separately, for example under a source-access or support agreement, the agreement's confidentiality terms cover that material. Nothing you observe by running the distributed software is confidential, and measured performance is always yours to publish.

Models and Third-Party Components

Model weights are not licensed under this agreement. Paddock downloads, loads and serves them, but each model comes from its own publisher under its own terms, which can restrict what it may be used for and what may be done with its output. Complying with those terms is yours to do. The catalog is on Supported Models.

Paddock also incorporates open-source components and redistributes certain third-party binaries under their own licenses. Those are listed in the THIRD-PARTY-NOTICES file that ships with the release, and nothing in the Paddock agreement affects the rights those licenses give you.

The Agreement

This same text ships as LICENSE.txt inside every release archive, next to THIRD-PARTY-NOTICES.txt. The copy in your download and the copy on this page are the same file.

PADDOCK END-USER LICENSE AGREEMENT (EULA)

Copyright (c) 2026 Truespar. All rights reserved.

This End-User License Agreement ("Agreement") is between you (an individual or
a single entity, "Licensee") and Truespar ("Licensor") for the Paddock
software, including its source code, binaries, kernel packs, documentation, and
associated files (the "Software"). Installing, copying, or using the Software
means accepting this Agreement; if Licensee does not accept it, Licensee must
not use the Software.

Paddock is proprietary software that Licensor makes available free of charge.
This Agreement is deliberately short: it grants broad rights to use, deploy,
and pass on the Software, and restricts only what keeps Licensor's
implementation from being taken apart and reused.

1. GRANT OF LICENSE

   The Software is made available free of charge, without usage limits, for
   personal and commercial use.

   The rights in this Section apply to the Software as Licensor distributes
   it, in binary and release-archive form. Source code is not part of the
   free distribution; if Licensor provides it, it is provided only under a
   separate agreement and Section 5.

   Subject to Section 2, Licensor grants Licensee a worldwide, royalty-free,
   non-exclusive license to:

   (a) Install and use the Software on any number of machines Licensee owns or
       controls, for any purpose, including evaluation, development, and
       production, personal or commercial.

   (b) Serve models with it, and build applications and services on top of it
       through its published APIs, Model Context Protocol surface, and CLI.
       What Licensee builds this way is Licensee's own.

   (c) Measure, benchmark, and publish the performance and behaviour of the
       Software. This right is granted expressly and needs no prior consent.

   (d) Redistribute the Software as complete, unmodified official release
       archives published by Licensor, with all license files, notices, and
       attributions intact, for example through mirrors and package managers.
       Each recipient licenses the Software directly from Licensor under this
       Agreement. Modified, repackaged, or partial copies may not be
       redistributed.

   These rights are perpetual and irrevocable for each version of the Software
   Licensee has received, subject only to Section 8.

2. RESTRICTIONS

   These are the only restrictions. Licensee shall NOT:

   (a) Reverse engineer, disassemble, decompile, or otherwise attempt to
       derive the source code, algorithms, kernel internals, or other
       non-public technical details of the Software from the binaries, the
       kernel packs, or any other artifact Licensor distributes.

   (b) Modify, adapt, or create derivative works of the Software, or extract,
       repack, or reuse any part of it, in particular its GPU kernels and
       kernel packs, separately from the Software as distributed.

   (c) Remove, alter, or obscure any proprietary notice, label, or mark on the
       Software, including the third-party attributions named in Section 3.

   Nothing here limits Section 1(c) or 1(d). Where applicable law grants
   Licensee a non-waivable right to decompile or analyse the Software, such as
   the interoperability rights under EU Directive 2009/24/EC, that right
   applies to its minimum legal extent notwithstanding this Section.

3. OWNERSHIP AND THIRD-PARTY COMPONENTS

   Licensor retains all right, title, and interest in the Software; this
   Agreement grants a license only. The Software incorporates open-source
   components and redistributes certain third-party binaries under their own
   terms, listed in the THIRD-PARTY-NOTICES file shipped with it, and nothing
   here affects Licensee's rights under those licenses.

4. MODEL WEIGHTS AND OTHER CONTENT

   The Software can download, load, and serve machine-learning model weights
   and related artifacts ("Models"). Models are NOT part of the Software and
   are not licensed under this Agreement: each is licensed by its publisher
   under its own terms, which may restrict how it may be used or what may be
   done with its outputs. Licensee is responsible for complying with those
   terms and for the content Licensee submits to or generates with the
   Software, and shall hold Licensor harmless from third-party claims arising
   out of Licensee's use of a Model in breach of them or of applicable law.

5. CONFIDENTIALITY OF DISCLOSED SOURCE

   This Section applies only where Licensor separately provides Licensee with
   source code or other non-public technical material, for example under a
   source-access or support agreement. It does not apply to the Software as
   distributed or to anything Licensee observes by using it: measured
   performance and observable behaviour are not confidential, and Section 1(c)
   governs their publication.

   Licensee shall keep such material confidential, use it only for the purpose
   for which it was provided, and disclose it only to employees and
   contractors who need it for that purpose and are bound by equivalent
   obligations. The usual exceptions apply: material that is or becomes public
   through no fault of Licensee, was already rightfully known to Licensee, is
   independently developed without reference to it, or must be disclosed by
   law. These obligations last five (5) years from disclosure, and as long as
   the material remains a trade secret.

6. FEEDBACK

   If Licensee sends Licensor suggestions or other feedback about the
   Software, Licensee grants Licensor a perpetual, worldwide, royalty-free,
   irrevocable license to use and incorporate it without restriction or
   compensation. Licensee keeps ownership of its feedback.

7. NO WARRANTY AND LIMITATION OF LIABILITY

   THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
   IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
   NONINFRINGEMENT. LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE
   ERROR-FREE, THAT IT WILL RUN ON ANY PARTICULAR HARDWARE, OR THAT ANY OUTPUT
   OF A MODEL SERVED THROUGH IT WILL BE ACCURATE OR SUITABLE FOR ANY PURPOSE.

   TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR'S TOTAL LIABILITY UNDER
   THIS AGREEMENT SHALL NOT EXCEED FIFTY US DOLLARS (USD $50.00) OR, IF
   GREATER, THE FEES LICENSEE PAID LICENSOR FOR THE SOFTWARE IN THE PRECEDING
   TWELVE (12) MONTHS, AND LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT,
   INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOST
   PROFITS, DATA, BUSINESS, OR GOODWILL. Nothing here excludes liability that
   cannot be excluded by law, including for death or personal injury caused by
   negligence, or for fraud.

8. TERM AND TERMINATION

   This Agreement takes effect when Licensee first uses the Software and runs
   indefinitely. Licensee's rights under Section 1 end only on a breach of
   Section 2, in which case they terminate automatically and Licensee must
   stop using the Software and destroy its copies. Models and data created by
   Licensee are unaffected. Sections 2 through 7, 9, and 10 survive.

9. GOVERNING LAW

   This Agreement is governed by the laws of the State of Delaware, United
   States, without regard to its conflict-of-law rules; the UN Convention on
   Contracts for the International Sale of Goods does not apply. Disputes are
   resolved in the courts of Delaware, except that Licensor may seek
   injunctive relief in any competent court to protect its intellectual
   property or confidential information. Nothing here excludes any right
   Licensee has as a consumer under the mandatory law of its country of
   residence.

10. ENTIRE AGREEMENT

   This Agreement is the entire agreement between the parties regarding the
   Software and supersedes all prior representations and agreements about it.
   If any provision is unenforceable, the rest remains in effect.
   Modifications bind only if agreed in writing.
