We use http://geojson.io/ regularly do convert data formats, inspect *.geojson files or other map related work. All inside the browser. It's open source, still maintained but IMHO reached a stage where it had to become a commerical, optionated, supported product. Or rather a different product like Placemark to fill the niche. Too many users had different use cases for geojson.io, sharing files with others is cumbersome and some features on the wishlist are super complex to build.

During testing I was able to load a 40.000 points data file (large cities and some attributes like name, elevation) into Placemark and browse around, search, filter, add new points fine. It's a powerful tool. The monthly pricing likely only attract users in the geospatial industry and companies so hopefully the marketed is big enough to generate enough revenue. I'm looking forward to some kind of CLI tool or API to auto-upload/download files to fit our workflow at some point.

Thanks! Just in case it isn’t clear, geojson.io is from the same folks (okay, folk, me) as Placemark. My hope with Placemark is to keep maintaining it and improving it, while unfortunately geojson.io has been untouched for a few years.
