Years ago I built FPOimg (fpoimg.com) as a placeholder image generator that I kept wishing existed.

I've always wanted to keep it simple, open source, fast, and reliable. I've recently updated with additional features to make it more modern, useful, and pretty.

The basics work like you'd expect: /800x600 gives you an 800×600 image, /500x200/Hello adds a caption. Nothing revolutionary there.

I added: - Gradient backgrounds — 20 presets (/800x600?gradient=sunset) or pass your own two colors - 148 CSS named colors — /400x300/tomato/white instead of hunting for hex codes - Multiple formats — change the extension to get .webp, .gif, .png, or .jpg (and experimental SVG support) - Multiline text — line breaks in captions, auto-wrapping for longer text

It's Flask + Pillow, nothing fancy on the backend. Self-hostable if you prefer that.

Happy to hear what's missing or what would make it more useful.
