SeaStack

What is SeaStack?

SeaStack is a new series of open-source starter kits and reference apps from DigitalOcean, built to help developers ship real apps, faster.

It's our way of saying: "Here's how you can build real things with DigitalOcean — and here's the source code to get started."

Each SeaStack app is production-ready, easy to deploy, and shows how DigitalOcean services work together in practice. Think: authentication, billing, storage, email, AI — all wired up and ready to go.

We currently have SeaNotes and SeaSupport — with more SeaStack apps on the way.

Solve the Right User Stories (So You Don't Have To)

SeaStack apps handle the foundational features most products need:

All of this is baked in — so you can skip the glue work and focus on building your actual product.

Work Great with LLMs

You can use SeaStack apps in two ways:

  1. Starter Kit — Clone the repo, build your business logic on top, and launch.
  2. Reference App — Point Claude, ChatGPT, or Cursor at the codebase and say:

"Build me something like this… but for customer support tickets."

"Rewrite this to manage bookings instead of notes."

"Add a feature that lets users tag notes and filter by tag."

Because the infra is already handled, LLMs can focus on your logic, not boilerplate setup.

Try It Out

Ready to get started? Check out the GitHub repos for both SeaStack apps.

Everything's set up: auth, billing, email, storage, AI, deployment. You can use them as a starting point or just see how things are wired together.

What's Next

We currently have SeaNotes and SeaSupport — with more SeaStack apps on the way. We'll be iterating on this and releasing more kits as part of SeaStack, so if there's something you'd like to see baked in, or a service you wish we'd integrate next, let us know!

We can't wait to see what you ship!
