The Minecraft Overviewer

a high-resolution Minecraft world renderer with a LeafletJS interface


The IRC channel has moved

Due to recent changes in freenode's ownership and the ensuing events, our IRC channel, #overviewer, has been moved to Libera.Chat. If you need help with the Overviewer, it will from now on be provided over there. Our webchat has been updated to reflect this, as has our documentation.

Overviewer 0.15 is out, supporting Minecraft 1.15

Overviewer 0.15 has just been released, supporting all the new 1.15 blocks and working correctly with that version of the textures.

You can download the latest release as always on our download page.

If you're sticking with Minecraft 1.14, don't worry, you can just download the 1.15 textures and Overviewer will still be able to render your world.

Overviewer 0.14 is out, making the move to Python 3

As all of you might know, Python 2 is on its death bed, so it's about high time we finally made the move to Python 3. And after a lot of large changes and small fixes, we've finally done it. This work was done by CounterPillow (me), SteadBytes and agrif, and we're very appreciative of it.

This also means we've dropped prebuilt binaries for CentOS 6, because it's old and smelly. If you're still using CentOS 6, make the move to CentOS 7.

The only breaking changes during this move is that the config file imports for optimizeimg have slightly changed. So, instead of

from optimizeimages import foo, bar

the optimizeimages module now needs to be prefixed with a period, like this:

from .optimizeimages import foo, bar

The same goes for Observers, so it's now:

from .observer import foo, bar

And that's really all there is to it. We've also updated build and install instructions in our documentation, and provide prebuilt binaries for Windows and Linux our download page.

If you encounter any issues, feel free to report them on GitHub, and if you need help you can come talk to us and the wider community on both IRC and Discord.

Overviewer v0.13 is out, supporting Minecraft 1.13

We never quite knew whether it would come to this, but yes, Minecraft 1.13 support has finally arrived in the main Overviewer branch. This was thanks to the hard work of gmcnew, RedSparr0w, jvaskonen and agrif.

You can grab the binaries as usual on our downloads page.

2019 marks the ninth year of Overviewer's long and varied history, which means that we probably have people looking at Overviewer maps now that are younger than the project itself, which is impressive! During this time, 2553 commits have been made to the repository by 108 contributors from all over the world, for which we are incredibly grateful for.

If you need help with Overviewer or just want to say hi, you can reach us on IRC or Discord. We also have a Twitter account, @mcoverviewer, if you're into that.

Overviewer Switches to Leaflet

For years, Overviewer has been using the Google Maps API to display its rendered maps. This means we just use their JavaScript files, and none of their data. In fact, we wouldn't even be allowed to ship their JavaScript file ourselves; the JS file is requested from Google on a page load.

However, Google started restricting their API, forcing all new Overviewer users to get a (free) API key from Google just to use one JS file. Just a few days ago, Google has announced that they will require everyone to sign up with a credit card to make use of the Google Maps API, which is unacceptable for our use-case.

Therefore, Overviewer now uses Leaflet, a free as in freedom map framework. In addition to our users no longer requiring Google Maps API keys, this also means that maps can now be viewed without an internet connection, and are smoother to use. Furthermore, we're now no longer at the whims of Google, who have proven to be bad to rely on.

Some features may still be missing from the Leaflet version, but all in all we believe it is a very usable experience. If you notice deficiencies, feel free to submit a pull request or open an issue.
