Why we built these tools

At WonderLaunch, our goal is to help indie hackers and solo founders successfully launch their products. We realized that launching requires juggling a dozen different micro-tasks: generating tracking links, resizing screenshots, calculating margins, and writing copy. We built this directory so you have a single, reliable toolkit.

Are these tools really free?

Yes. Every single tool in the WonderLaunch directory is 100% free to use forever. There are no paywalls, no hidden subscription fees, and we don't even ask you to create an account or provide your email address to use them.

Do you store my data?

No. We take privacy extremely seriously. All of our tools are built deterministically and process data entirely on your client (in your web browser). Whether you are resizing images, calculating financial runway, or building UTMs, none of that data is ever sent to our servers.

Who are these tools for?

These tools are engineered specifically for startup founders, indie hackers, solo developers, and growth marketers who are preparing to launch a product on discovery platforms like WonderLaunch, Product Hunt, or Hacker News.
