This one is really slick, I wonder how it works with larger data sets. I'll check it out later. Geojson.io is a nice one but I second your comment, anything on the larger side it just crashes for me. I end up just using QGIS with a text editor open for the geojson editing. It ends up being a game of trial and error that gets very tedious.
Good point. Performance is a problem on these tools and I need to do some work on that front as well. My email is on geoman.io - send me a data set and let me try. I will make improvements here in the next weeks.
Another feature which geojson.io provides over the tool presented here, is the table view which makes editing / formating / adding information to a large set of features simple and accessible.
File management (including open local and hosted files) and the availability of different map layers are appreciated features for daily work as well.

meta data management is definitely on my list - thanks for your feedback
I've also been using geojson.io for most of my workloads. The large dataset handling definitely leaves something to be desired.
One thing that they do offer though is the option to view satellite map data, which doesn't seem to be available here. I'd love to give this a shot, but most of my workloads are really imagery dependent, so geoman doesn't seem to be an option.

Thanks for the feedback, consider it done (very soon)
This seems very similar to geojson.io . I'm curious, are you leveraging their source somehow?
nope. Not at all.
Looks nice! Sexier than geojson.io, but, as others have pointed out, you need to get it up to feature parity before a lot of us would consider using it for serious work.
I'll try it out and send some more feedback your way.

will do - it's v1 and we will get there
I use GeoJSON all the time in mobile robotics. For indoor robotics, we are using our own local coordinate system. This means that we "lie a little bit" about the GeoJSON spec, treating x and y as linear metres in a flat world.
tl;dr: I would love if more tools allowed you to hide the map and just ignore the details of the CRS/Projection. I do so much work on and around Null Island as a result. QGIS has been _very_ good at this. But most online tools always assume use cases are WGS84.

Oh, absolutely this! I work on game heatmaps (Halo), player path analysis, etc. Having a flat-world coordinate system with a customer-supplied map is critical.
Thank you for the feedback, guys... this is awesome!
We aim to provide the best GeoJSON editor out there. Feedback is most welcome!
As someone who has to edit GeoJSON ~monthly, these would be useful for me:
- edit polygons (ie: to add more points). It'd be useful to click one of the points to add a point after it (then click the next point to close it)
- import (fwiw: my geojson comes from postgres/postgis ST_AsGeoJSON)
- save to gist (or some other share feature). I use this one to show maps to non-tech colleagues for signoff.

In the editor, I do see Shapefile in the dropdown for downloading. It's unavailable however. (Same for WKT and TopoJSON). Are these paid features?
They will come soon. No paid features planned yet but we will see how much effort the tool is for us in the future. For now, most of these formats will be supported for free.
I love this. It could have been really great to have this about 10 years ago, when I was looking for a quick way to manually partition cities' neighborhoods through GEOjson polygons.
Why do you allow users to draw circles when they aren't actually a proper GeoJSON geometry. It's just a Point geometry with a custom (unit-less) radius property.
The basis for the editor is my open source drawing plugin for leaflet - Leaflet-Geoman.
It supports circles because Leaflet supports circles. GeoJSON is just a format to export Leaflet-Layers - so we made Circles work even though it's custom.
You're definitely right about the unit-less part. Something I should be fixing.

Would be good if wkt can also be supported as input
thanks, I put it on the list
This is kick ass!
I can think of some incredible use cases I could put to work today!

Go ahead :-)
I use http://geojson.io quite frequently to modify geojson data sets, but there are some annoying bugs especially when working with larger data sets. One key feature they have is being able to swap between multiple tile providers, so you can compare where certain features are positioned on different maps.
I recently started a new Geo meetup here in Tokyo, https://GeoTokyo.com - I'll share at the next event.
Thanks
