Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

minibanana

Tiny CLI for generating images with OpenRouter.

Install

npm install -g minibanana

Or run it with npx:

npx minibanana --prompt "A friendly whale" --model "bytedance-seed/seedream-4.5" --out myimage.png

Usage

minibanana --prompt "A friendly whale" --model "bytedance-seed/seedream-4.5" --out myimage.png
minibanana --prompt @prompt.md --model "bytedance-seed/seedream-4.5" --out myimage.jpg --quality 80
minibanana --prompt @prompt.md --model "bytedance-seed/seedream-4.5" --aspect-ratio 16:9 --out myimage.jpg
minibanana --prompt @prompt.md --in image1.jpg --in image2.jpg --model "bytedance-seed/seedream-4.5" --out myimage.jpg

Options

  • --prompt <prompt>: Required. Prompt text, or @path/to/file.md.
  • --model <model>: Required. OpenRouter model name.
  • --out <file>: Required. Output path for generated images. If the API returns multiple images, extra files are written as name2.ext, name3.ext, and so on.
  • --in <image>: Optional. Repeat to attach one or more input images.
  • --api-key <key>: Optional. Falls back to OPENROUTER_API_KEY.
  • --quality <number>: Optional. JPEG quality from 1 to 100. Defaults to 70.
  • --aspect-ratio <ratio>: Optional. Passed through to OpenRouter as image_config.aspect_ratio.

Notes

  • Input images are sent to OpenRouter as data URLs.
  • The CLI writes returned images to --out, then appends 2, 3, and so on before the extension if multiple images are returned.
  • The CLI converts the returned image to match the --out extension.
  • Supported output formats are .jpg, .jpeg, .png, .webp, .avif, .gif, .tif, and .tiff.
  • Aspect ratio validation is intentionally minimal: it only checks x:y syntax like 16:9.
