Professional work around an open core

Priority support and tailored QZX work

Organizations and teams can request scoped priority support, compatibility validation, Result Contract interoperability pilots, sponsored development, or a QZX adaptation for a specific environment. QZX Core remains free and open source.

Start a 2-minute brief

Availability, response targets, deliverables, price, and publication boundaries are agreed in writing before work begins.

QZX Professional Services

Tell us what outcome you need

Start with only the essentials: request type, your name, work email, and the outcome you want. Technical context, timing, budget, and confidentiality are optional and can be discussed later. You will receive a reference for follow-up.

* Required fields

Add optional context

Organization, technical environment, timing, budget, or confidentiality. Useful if you already know it, but not required to start the conversation.

This commercial inbox is separate from analytics. QZX may record that you started using the form, but field values are never sent to analytics. Submitted data is not sold or used for advertising. Requests that do not become active work are deleted within 12 months; you may request deletion at [email protected].

Describe the result you need, without passwords or other secrets. Include your request reference if you already received one.

Priority support

Reserve focused technical attention

Agree on a first-response target for triage, reproduction, upgrade planning, and technical guidance. Payment reserves time and accountability; it does not guarantee a fix, a favorable finding, or 24/7 availability.

Compatibility

Validate an exact environment

Request testing or adaptation for a particular Windows, Linux, or macOS release, Python version, terminal, browser, architecture, agent, or policy. The proposal identifies the matrix and any access, hardware, or licenses needed.

Interoperability pilot

Test QZX Result Contract v1 in a real workflow

Define a bounded pilot for a CLI, MCP server, agent platform, or internal automation tool. For structured-output MCP producers on 2025-06-18, 2025-11-25, or 2026-07-28, the pilot can map QZX Result Contract to outputSchema and structuredContent, record the schema-strength mode, verify completed success/failure consistency with isError, and publish a reviewable conformance report, deviations, reusable validators, and limitations without purchasing endorsement or control of the open specification.

Review the MCP interoperability profile

Sponsored development

Scope a feature or integration

Propose a QZX feature, integration, or modification with a concrete outcome. Reusable improvements are intended for the open project under Apache-2.0; client data, credentials, and genuinely specific materials remain protected.

What happens after you send the brief

  1. 1. Brief

    Describe the useful result

    Include the operating system and exact version, QZX and Python versions, impact, desired evidence, deadline, and any confidentiality constraints.

  2. 2. Feasibility

    Confirm fit and capacity

    Alejandro reviews technical fit, available time, dependencies, risks, and whether a smaller discovery or reproduction step should come first.

  3. 3. Written scope

    Agree before committing

    The proposal states deliverables, response target, price, payment terms, acceptance evidence, confidentiality, and which improvements can be published.

  4. 4. Delivery

    Produce evidence, not promises

    The work is tested against the agreed environment and reported with results, limitations, and next steps. General improvements strengthen the open core whenever applicable.

A service agreement is not a donation

Donations support general maintenance without purchasing priority or deliverables. Professional services create a separate, scoped agreement. Essential security work is prioritized by risk, and no customer receives control of the general roadmap, private user telemetry, or a guaranteed favorable compatibility result.

Requests may be accepted, narrowed, scheduled, or declined according to capacity, feasibility, safety, and alignment with QZX.
