+title: Support Ghostty Development
+description: |
+  Ghostty is fiscally sponsored by Hack Club (501(c)(3)).
+  All donations are tax-deductible in the United States.
+---
+
+Ghostty is developed as non-profit work, supported by donations. The
+Ghostty project is owned by a 501(c)(3) non-profit organization, Hack Club, who
+operates as the fiscal sponsor for the project.
+
+We believe terminal and terminal-related technologies are critical
+infrastructure for modern computing and software development. Whether
+it's directly used by developers or indirectly used through products
+such as editors, CI logs, PaaS consoles, agentic tools, and more, terminals
+continue to be a foundational technology underpinning much of our
+modern computing ecosystem.
+
+Aligned with this belief, we develop Ghostty as a non-profit project.
+Being a non-profit provides important legal protections to the people and
+communities that adopt and contribute to Ghostty. Importantly, it means we are
+not beholden to commercial interests or investor pressure. Ghostty cannot be
+sold, pivoted, or shuttered on a whim — its purpose and stewardship are bound
+to the public benefit it was created to serve.
+
+## Donate
+
+<DonateCard
+  title="Support Ghostty"
+  description="Your contribution helps sustain development and keeps Ghostty free and open source for everyone. Donations are tax-deductible in the United States."
+  buttonText="Donate Now"
+/>
+
+7% of all donations go directly to Hack Club. This covers the administrative
+costs of fiscal sponsorship, but also supports [Hack Club's broader mission](https://hackclub.com/philosophy/)
+to empower the next generation of technically-minded individuals around
+the world.
+
+## Usage of Funds
+
+All funds donated to Ghostty go to one of three places:
+
+- **Contributors.** Some individuals who are writing code or maintaining
+  critical systems (such as community moderation) for Ghostty are compensated
+  for their time and effort. More details are in the contributor
+  compensation section below.
+- **Services.** Ghostty incurs various costs to operate, such as hosting
+  this website, our Discord bot, continuous integration systems, code signing
+  fees, etc.
+- **Upstream Projects.** Ghostty depends on many other open-source projects.
+  The funds may be used to pay it forward to these projects, too.
+
+All of Ghostty's finances down to individual transactions are
+[transparent](https://hcb.hackclub.com/ghostty), so you can see exactly how
+funds are being used and where donations are coming from.
+
+**Explicitly, no funds are used for the personal benefit of the
+project creator, Mitchell Hashimoto.** Not a single cent of Ghostty
+contributions goes to Mitchell or any projects directly affiliated with him.
+In addition to creating the project, Mitchell is Ghostty's largest donor,
+and for both legal and altruistic reasons, he will not accept any compensation
+from the project.
+
+<Important>
+  The non-profit structure of Ghostty was only recently established in December,
+  2025. As such, we are still refining our processes and reporting, such as what
+  upstream projects we intend to support and how.
+</Important>
+
+### Contributor Compensation
+
+Contributors who have consistently demonstrated high-quality work and friendly
+behavior in the Ghostty community may be invited to enter into a paid
+contributor contract.
+
+These contracts allow contributors to bill for a limited number of hours
+dedicated to Ghostty. All contributors are paid a single global rate, which
+is currently $60 USD per hour.
+
+Contributors maintain full autonomy over when they work and which tasks they
+choose to pursue. By the time someone is offered a contract, they have already
+shown sound judgment about what meaningfully advances the project, and we
+trust them to continue using that judgement.
+
+Contributors aren't limited to code contributors to the core of Ghostty,
+but also include infrastructure such as our Discord bot as well as
+community management and moderation.
+
+All contributor contracts are issued at the discretion of the project lead.
+
+## Governance and Licensing
+
+The project continues to follow a [BDFL](https://en.wikipedia.org/wiki/Benevolent_dictator_for_life)
+model, with Mitchell Hashimoto serving as the project lead and final
+authority on all decisions, including the direction of funds within
+the non-profit (in accordance with the mission statement and legal
+requirements).
+
+The fiscal host, Hack Club, provides oversight to ensure that all
+project activities and fund usage align with the non-profit mission
+and legal obligations. They maintain a board of directors to provide
+this oversight.
+
+The project remains licensed under the MIT license, and the rights
+and permissions granted by that license remain unchanged.
+
+## Mission Statement
+
+The mission of Ghostty is to develop and maintain open-source terminal technologies that empower
+individuals and communities to learn, build, and participate in modern
+systems programming with a broad industry impact.
+
+## Relationship to Hack Club
+
+Ghostty is fiscally sponsored by Hack Club, a registered 501(c)(3) non-profit.
+
+[Fiscal sponsorship](https://en.wikipedia.org/wiki/Fiscal_sponsorship) is a
+legal and financial arrangement in which a recognized non-profit extends its
+tax-exempt status to a project that aligns with its mission. This allows
+Ghostty to operate as a charitable initiative while Hack Club manages
+compliance, donations, accounting, and governance oversight.
+
+We decided to pursue fiscal sponsorship rather than forming a new nonprofit
+for several reasons:
+
+- **Cost.** There is significant financial cost and overhead associated
+  with forming and maintaining a nonprofit organization. We calculated
+  that the 7% fee paid to Hack Club would be substantially lower than the
+  overall costs of managing a standalone nonprofit.
+
+- **Speed.** Forming a new nonprofit can take months or even years, especially when
+  applying for federal 501(c)(3) determination. Fiscal sponsorship allowed
+  Ghostty to begin accepting tax-deductible donations and operate under a
+  charitable structure on a much faster timeline.
+
+- **Accountability.** Working under an existing nonprofit adds an additional layer
+  of structure and stewardship. Hack Club provides financial oversight, legal
+  guardrails, donation reporting, and compliance support—including IRS, audit,
+  and grant-tracking requirements. This ensures Ghostty operates transparently,
+  ethically, and in alignment with nonprofit best practices from day one.
+
+- **A good cause.** There are other, for-profit non-profit management
+  companies available that charge a similar fee structure to manage
+  all the overhead of a nonprofit. With Hack Club, we pay a similar fee (7%),
+  but that fee goes towards another non-profit with a mission we support.
+  As Zach Latta, Hack Club's founder, put it: "it is a good-for-good trade."
