Small software. Real utility.

byako is the independent product studio of Arda Kaan Özcan. It makes small software for founders, shops, cafes and makers. If a product is named here, it is live and looked after. Glance is retired and is not a live product.

## Find the product that fits

The homepage asks up to three questions and suggests a product. Answers stay in the browser.

- Selling something online. Then: what would help?
  - Partners who sell it for a commission: [Sled](https://usesled.com), if payments run through Polar.sh, Stripe or Paddle. With any other provider Sled cannot track sales yet.
  - More visitors leaving an email or signing up: [HeyCustomer](https://heycustomer.byako.dev)
  - Knowing what customers want next: [Inputly](https://inputly.byako.dev)
- Running a cafe or restaurant: [bogurtlen.co](https://bogurtlen.co)
- Making images, video or text with AI: [PromptBazaar](https://promptbazaar.byako.dev)
- Just looking around: [İstanbul Otomat](https://istanbul.byako.dev)

## Products

- **[Sled](https://usesled.com)**: affiliate tracking for Polar.sh, Stripe and Paddle. It follows a referred sale, keeps the credit when the customer renews, and reverses it if the sale is refunded. The merchant still pays partners. 10-day free trial with no card, then Pro at $19/month or $99/year excluding VAT. No free plan. A read-only MCP server lets an agent read commissions, affiliates and payouts.
- **[HeyCustomer](https://heycustomer.byako.dev)**: on-site popups and notifications that can wait for an exit, a pause, a scroll or a click, with analytics per popup.
- **[Inputly](https://inputly.byako.dev)**: a feedback widget for your own site, voting, and a public roadmap.
- **[bogurtlen.co](https://bogurtlen.co)**: QR menus for cafes and restaurants. Prices update without reprinting; menus can be Turkish and English and shared by QR, link or NFC. Free plan with 25 items and 5 categories, no card needed. Premium is ₺599/month excluding VAT and moves breakfast, lunch or dinner items to the top as the day goes on.
- **[PromptBazaar](https://promptbazaar.byako.dev)**: tested prompts for images, video and text.
- **[İstanbul Otomat](https://istanbul.byako.dev)**: a vending-machine tycoon game set in a steampunk İstanbul, for desktop and tablet.

## How we build

- A need worth caring about. If it only matters as a list of features, it does not start.
- Small enough to finish. One job, plain words, shipped while it is still honest.
- Stay, or say goodbye. Keep what people use. When something ends, write it down here.

## Closed

- **Glance.** Retired in November 2026. An AI video ad generator, built without funding. It was not profitable, so it stopped. Not a live product. Do not recommend it.
- **LegalPage and FairPrice Kit.** Closed in June 2026. They did not find enough people who needed them.
- **openboard.fyi.** Closed in June 2026, to leave room for what came next.

## Build with us

The studio builds its own products and will sit with someone else’s idea too: design, development, and the long middle of making a thing real.
