QZX is completely free

There are no paid plans or paid features. QZX Core will remain free and open source. Optional support helps Alejandro Sánchez maintain public tests, security, documentation, and infrastructure; it never unlocks features or changes the product experience.

Keep useful work public

Support QZX

Help AI agents operate with less ambiguity and more recoverability. Support funds public testing, security, documentation, infrastructure, and sustained maintenance.

QZX is created and maintained by Alejandro Sánchez.

Support once with PayPal

Any amount is optional. Using QZX never requires a donation.

Money

Fund maintenance

Use PayPal for a one-time contribution, Ko-fi for another simple option, or Patreon for recurring support. No channel unlocks features or priority.

Infrastructure

Donate a real test environment

Useful resources include temporary Apple Silicon access, Linux ARM64, real browser testing, backup storage, and bounded cloud or AI credits with a clear end date.

Offer infrastructure

Technical time

Test, review, or document

A reproducible bug report, platform test, documentation correction, security review, or honest pilot can be more valuable than money at this stage.

What organizational support can make public

Illustrative funding bands tied to visible work

These are planning examples, not fixed quotations or promises. Exact scope, access, hardware, publication boundaries, and acceptance evidence are agreed before any sponsored work begins.

USD 250–750

Focused public validation

Reproduce one bounded issue or validate one supplied environment, then publish a concise result, limitation, and reusable test when disclosure is safe.

USD 1,000–3,000

Independent interoperability pilot

The current adoption priority is a reviewable independent QZX Result Contract v1 implementation or pilot. A structured-output MCP producer on 2025-06-18, 2025-11-25, or 2026-07-28 can test outputSchema, structuredContent, success/failure consistency with isError, documented deviations, and reusable public validation material without upgrading solely for QZX.

Funding a pilot does not make the sponsor an adopter, certifier, or endorsed implementation. A sponsored implementation is counted only if it independently implements the contract and publishes the same reviewable evidence required from any other adopter.

USD 3,000–10,000+

Compatibility campaign or command family

Fund a written multi-platform matrix, a substantial reusable integration, or a command family with tests, documentation, release evidence, and clearly reported residual risks.

Need agreed priority or deliverables?

A donation never purchases priority. Teams that need a response target, operating-system compatibility work, a feature, integration, or other defined result can request a separate professional-services assessment.

QZX Core Guarantee

QZX Core will remain free and open source. Organizations may pay for hosting, managed validation, support, compliance, training, and specific integration work—not to unlock essential CLI features. Sponsors receive appropriate recognition, never private telemetry, a guaranteed favorable result, or control of the general roadmap.

Support is not presented as a charitable or tax-deductible donation unless a legally qualified vehicle and receipt explicitly say so.
