For non-profits

Your mission,
built like a reef.

A coral reef isn't the work of one heroic creature. It's thousands of tiny polyps, each adding a little, until there's a living structure that shelters a whole ecosystem far larger than themselves. A non-profit runs the same way — so build it the same way. Post a project, gather a crew of vetted vibe coders, and raise something that shelters your whole community. No six-figure agency invoice.

Why a reef

Big things, built by many small hands.

A reef exists to house and nourish others, not to enrich itself. That's the whole idea of a non-profit — which is exactly why it's the metaphor we build around.

The polyp

Every contribution is small

A donor. A volunteer's Saturday. A few hours of a builder's time. On its own each one is modest — a single polyp laying down one small fleck of calcium.

The reef

Together they become structure

Those small acts accrete. In one shared crew workspace they turn into real tools, a shipped product — something durable that outlasts any single grant cycle.

The ecosystem

And the structure shelters everyone

What you build houses and feeds a community far larger than the org itself — the people you serve, the volunteers you lean on, the next org that learns from you.

How it works

Post today, building in days — not months.

Post a project
01

Post your project

Describe what you need built, your timeline, and whether it's paid or volunteer. Ten minutes, no jargon.

02

Gather your crew

Vetted vibe coders apply. Review their shipped work and pick the builders who fit your mission.

03

Build & shelter

Build together in a shared crew, ship it, then give it a public page that rallies more support your way.

Case study: Beach Atlas

Beach Atlas
Tidelines · Ocean conservation

An offline map that turns beach walks into cleanup data.

Tidelines posted a project on a Tuesday. By the weekend they'd gathered a crew of three vibe coders. Six weeks later Beach Atlas shipped: an offline-first app volunteers use to log coastal plastic, even with no signal on the shore. Hundreds of small walks, one shared reef of data.
