MapDevelopers Alternative — Modern Radius Maps with KML Export

MapDevelopers (mapdevelopers.com) is a long-running suite of free web tools for mapping, geocoding, and distance calculation. The Draw Circle Tool is one of its most-used utilities, offering quick radius circle drawing on a Google Maps base with address search, multiple circles, drag-to-reposition, and custom colors. The site is long-running and aimed at casual web users.

MapDevelopers is free and requires no account. The site displays ads on the tool page. There is no paid tier, no trial, and no signup flow. The tool runs on the Google Maps JavaScript API, which means it depends on Google's terms of service and API availability.

Map With Radius exports KML and PNG for free. MapDevelopers does not export in either format, so anyone who needs to load their radius into Google Earth, a GIS tool, or a document has to screenshot or recreate the shape elsewhere.

We run on OpenStreetMap via Leaflet, not Google Maps. That matters for anyone embedding the tool into their own site — no Google API key, no quota, no per-load billing.

Our tool is designed mobile-first. MapDevelopers works on mobile, but the controls are cramped and the interaction patterns assume a cursor. Drawing a radius on a phone is smoother on Map With Radius.

MapDevelopers' Draw Circle Tool renders its base map using the Google Maps JavaScript API. For a user just sketching a quick radius, that's invisible — the map loads, you draw a circle. For anyone considering embedding, scripting, or building a workflow on top, it's a structural fact worth understanding.

Google's Maps Platform charges per-load fees beyond a monthly free credit that production-scale embeds quickly exceed. MapDevelopers absorbs that cost on the tool page and offsets it with display advertising. The implications for users:

• You can't embed the tool yourself for free. If you wanted to put a radius tool in an internal company app or a public-facing site, replicating MapDevelopers' approach means provisioning a Google Cloud project, billing account, and API key — and absorbing the per-load cost once the free tier is exceeded.
• Map style and POI labels follow Google's product roadmap. When Google changes how restaurants or transit stops are displayed, MapDevelopers changes with it. That's sometimes welcome (cleaner labels), sometimes not (removed features, deprecated map styles).
• Terms of service follow Google's. Saving Google Maps map tiles offline, bulk-scraping, or commercial redistribution of derived imagery is restricted by Google's Maps Platform terms. The same applies to anything you build on top of MapDevelopers.
• The data is Google's. Place names, road geometry, and POI listings are Google's proprietary dataset. That's often the most accurate option for North American businesses; it's sometimes thin for informal settlements, recent road changes in non-English-speaking markets, or niche POIs.

Map With Radius runs on OpenStreetMap via Leaflet. OSM is community-maintained and free to use commercially, with attribution. For embedding, you can iframe the tool into another site without provisioning anything. For accuracy, OSM matches Google closely in dense Western markets and sometimes outperforms it in regions where the local OSM community is active (much of Europe, parts of Asia and Africa).

None of this is an argument that one is universally better. It's a structural tradeoff: Google's dataset and visual style versus OSM's openness and embeddability. Pick the one whose constraints don't bind on your use case.

MapDevelopers is simple, fast, and established. If you need the Google Maps visual style — satellite view, specific POI labels, Street View integration — MapDevelopers delivers it. It also pairs well with other MapDevelopers utilities if you are already mid-workflow on their site for geocoding, distance calculation, or zip-code lookup.
