Just wanted to note that if you haven&amp;#x27;t looked into OpenLayers in a few years, you absolutely should — it&amp;#x27;s astonishing how much it progressed: from something that I was so frustrated with that it prompted me to write Leaflet in the first place (11 years ago) to a modern, fast, well-engineered and lovingly maintained library.&lt;p&gt;It&amp;#x27;s especially great when you&amp;#x27;re doing complex GIS stuff and need a ton of features and formats supported out of the box. As for other libraries, I&amp;#x27;d recommend Leaflet for simple maps, and Mapbox GL for rich, highly interactive apps that benefit from vector rendering tech (I&amp;#x27;m biased since I contributed to both), but it&amp;#x27;s great to have OpenLayers in the mix — there&amp;#x27;s a library for anyone&amp;#x27;s needs, cross-inspiration moves all three forward, and the mapping software landscape in general is greater than it has ever been.</text></comment>

Widely known, suitable for mostly simple use cases.&lt;p&gt;- Mapbox GL JS. State of the art library based on WebGL. Mapbox started off with a fork&amp;#x2F;extension of Leaflet called Mapbox.js but over time has moved on and created the Mapbox GL JS library from the ground up. Very fast, but requires a GPU due to WebGL.&lt;p&gt;- OpenLayers. Often used by more professional users. Probably the most features complete library. Also usable without a GPU.</text></comment>
