🐇 The Story behind Banny

How a missing Obsidian banner turned into this:

Banny started because I wanted nice banners for my Obsidian notes and couldn't justify opening an image editor every single time, let alone paying for an online "Notion banner creator" tool just to get more than three designs. So I built my own instead.

It was rough for a while, half-working and only running locally. But having banners that actually matched my uni courses, each with its own color, an emoji, a bit of personality, made my notes feel like mine. That was motivation enough to see it through. Eventually I sat down with Cursor, cleaned everything up, and gave the project a proper identity, mascot included. GitHub Pages took care of the rest.

🐇 The Story behind Banny

How a missing Obsidian banner turned into this:

Banny started because I wanted nice banners for my Obsidian notes and couldn't justify opening an image editor every single time, let alone paying for an online "Notion banner creator" tool just to get more than three designs. So I built my own instead.

It was rough for a while, half-working and only running locally. But having banners that actually matched my uni courses, each with its own color, an emoji, a bit of personality, made my notes feel like mine. That was motivation enough to see it through. Eventually I sat down with Cursor, cleaned everything up, and gave the project a proper identity, mascot included. GitHub Pages took care of the rest.
