Georgios Nikitas Software
I'm an indie software maker shipping small, focused products in my own time — downloadable tools and lightweight web applications. Each one is designed to do one job well, with transparent one-time pricing and a clear license.
A focused lineup of products I design, build, and maintain myself — some ready to use today, others actively taking shape. Available releases are crafted with care for performance, privacy, and a clean user experience, and offered as one-time purchases: pay once and keep using the product under your license, with no subscriptions, hidden fees, or recurring charges.

After checkout on Lemon Squeezy, you receive a license key by email. Each product has its own delivery channel — the Brain Break CLI is installed from npm or Homebrew, Auto Garage runs in your browser (or can be self-hosted), and Brain Break Mobile (when released) will be installed from the App Store or Google Play. All of them then use the same activation flow: open the app, paste your license key into the activation screen, and the product unlocks.
All products offer a free demo so you can evaluate them before buying. Because of this, refunds are limited to critical defects and billing errors. See the full Refund Policy for details.

This is a small, indie software project run by Georgios Nikitas alongside a full-time job. Products are designed, built, and supported personally.
What is sold: Small, self-contained software products. Some are downloadable command-line tools (such as Brain Break), others are lightweight web applications (such as Auto Garage).
Who they are for: Individuals and small businesses that want focused, affordable software that does one job well — without the complexity or recurring cost of larger platforms. Each product targets a specific audience, described on its own listing.
How they are made and licensed: Each product is developed in-house. Buyers receive a non-transferable license to use the software for the intended scope (single user for personal tools, single small business for business tools). Source code stays under the developer's ownership.
Billing model: All current products are one-time purchases. No subscriptions are offered today. If a subscription product is ever introduced, it will be clearly listed on this page with its own pricing.
