Word from the Creator

Built for Builders
(by a beginner)

Hey I'm Lewis ๐Ÿ‘‹ and I've been following the indie dev scene for a while now. This December, I'm finally trying it myself. I'm starting by learning the reiterative cycle of ship โ†’ feedback โ†’ improve โ†’ ship by building 25 tools in 25 days. Each tool is a chance to practice shipping fast, gathering real feedback, and iterating quickly. If you're also on the journey of building in public, let's learn together. So have a play around with the site, leave some feedback, and let's make something great this December!

FAQ

Frequently Asked Questions

Got questions? We've got answers.

What is Ship Advent?

Ship Advent is a free advent calendar for developers! Every day from December 1st to 25th, we unlock a new micro-tool to help you code faster, debug smarter, and ship with joy. ๐ŸŽ„

Are all the tools really free?

Yes! Every tool is 100% free to use. Some advanced AI-powered tools require a free account to help us manage API costs, but there's no payment required.

Do I need to create an account?

Most tools work without an account. A few AI-powered tools (like the debugging assistant) require a free login so we can manage usage fairly. Sign up takes 10 seconds!

Can I use these tools after December?

Absolutely! Once a tool is unlocked, it stays free. Think of December as the grand reveal โ€” the tools are yours to use.

Who made this?

Ship Advent is built by Lewis Will (LWHSolutions) as a gift to the developer community. Follow along on X and Instagram for behind-the-scenes and updates!
