A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

MAZANOKE is a simple image optimizer that runs in your browser, works offline, and keeps your images private without ever leaving your device.

Created for everyday people and designed to be easily shared with family and friends, it serves as an alternative to questionable "free" online tools.

See how you can easily self-host it here:

Highlights from v1.1.5 (view full release note)

The focus of this release has been to improve the core foundation and file format support, but I'm planning to expand with more features further down the road in order to improve the usefulness of MAZANOKE (while still keeping the UX simple).

  • Support basic authentication for Docker setups.
  • TIFF file format support.
    • Convert from TIFFJPG, PNG, WebP, ICO
  • ICO file format support.
    • Convert from and to an ICO image.

---

I also feel incredibly honored that MAZANOKE was recently featured on several of my favorite communities:

It's been incredible to see the growth of the user base, with over 54,000 docker pulls for the previous release alone, and now reaching over 1400 stars! I never anticipated this at all and I'm truly grateful for the support!

I'd like to thank everyone who helped spread the word, whether through starring, word of mouth, community engagement, blog posts, or by packaging it for things like Unraid and NixOS, and everything in between!

It's JavaScript.

And it is slow, but not as slow as I expected it to be. I've optimized a photo I've taken with my DSLR, 6.3MB, 24MP, JPEG. It has taken ~50sec on this phone, in Firefox.

I know, it's a phone, but also, my phone can and does save, optimize, and apply filters to such images in <1sec.

If you are interested (and can pull together a bit of funding) I can look into how we could do this optimization in WASM.

[–] [email protected] 7 points 1 month ago (5 children)

Yes, it's all JavaScript and essentially relies on the Canvas API to compress the images, so the performance is heavily dependent of your device and browser. I haven't delved into WASM yet, but it would indeed open up doors for improvements, such a more file format support and more intelligent optimization. At the moment, working with canvas keeps things a lot more straightforward, however.

There is no funding I can provide at all (I've received 2 donations so far, which I'm very grateful for!). I just do this on my spare time, which I have a lot less of these days. I initially created MAZANOKE as a drop-in replacement for family and friends, specifically to those who tend to use questionable or ad-bloated online tools.

I did also forget to say it does look very nice, with animations and proper polish!
