The 0xSpectra collection
shAIrts
Good shirts. Useful work.
Support the people building secure, dependable open infrastructure.
The maintainers, the late-night problem solvers, the people making powerful tools available to everyone. Help give them the time to keep building.
What we supportWhere the money goes
Fund the people.
Show the work.
Open-source development takes time. This collection helps pay for it, with the funding arrangement stated before each release opens.
Independent projects
The named project receives the full net payout allocated to that release. 0xSpectra retains no share.
What does “net payout” mean?
The payout remaining after Custom Ink’s production costs and applicable deductions. It is not the shirt’s retail price. Each release will state its costs and allocation, and we’ll publish transfers and funded work as they happen.
People > Prompts is now available on Custom Ink. Net proceeds from this release fund AI development tool usage for k3sm contributors.
Our selection principles
Infrastructure
worth sustaining.
We look for projects that help systems operate securely and reliably, from an independent lab to an enterprise deployment.
A clear mission
A public charter or mission, a defined problem, and a clear account of who benefits.
Research before reinvention
Evidence of the need, an understanding of existing alternatives, and a reason for the chosen approach.
Responsible engineering
An open-source license, active maintenance, security reporting, testing, and honest documentation of limitations.
A working funding route
An active GitHub Sponsors page or a verified donation destination linked from the project’s GitHub funding setup.
A specific use for support
A named recipient and a useful scope of work. Contributor relationships and funding allocations are disclosed.
