Most of the applications and sites we use today are bound to show the location and various data on maps. Maps are used everywhere: from food delivery sites to online stores and complex applications for logistics companies.
Maps are used very widely in web design, and when presenting data, we usually expect them to be interactive. It can be the branches of an international company, statistics about countries or just destinations to visualize.
Maps that are pre-arranged help people find your business without having to spend time looking for your physical location manually.
One way or another, while developing another application you will definitely face the questions of working with maps. What tools should you use? Paid or open-source? Standalone or web-based?
Many different plugins and libraries that you will find on our list are built specifically to make it easy for people to find your business.
But Google Maps isn’t the only solution. Firstly, it does not provide too many customization options, such as custom marking and adding extra widgets to make your maps more interactive. Other than that, you might need maps specifically for contests, exploration, traveling, hiking, and much more. That’s why you may need open-source solutions.
In this article-comparison we will talk about different types of javascript tools for working with maps. We’ll look at the types of tools you can choose from, as well as the comparison options.
Classification of Mapping APIs
Due to a large number of different tools for working with maps, it would be good to categorize them to give a definition of each category.
In this article, the categories for Web mapping clients have been extracted from the projects’ descriptions. Thus, there are libraries, wrappers, toolkits, frameworks, and clients.
- Libraries: Expose classes and functions allowing to build applications at a higher level of programming;
- Wrappers: act as an interface between the caller and the wrapped code;
- Toolkits: more modular and easily integrated into a custom application;
- Frameworks: A reusable software template, or skeleton, from which key enabling and supporting services can be selected, configured and integrated with application code;
- Clients: ready-to-use web mapping applications.
This method of categorizing web mapping clients provides a first approach for distinguishing them, so you can select them more easily.
Comparison of Maps API
The comparison is presented in three parts to facilitate the reading:
- General description: Gives an introduction to each project;
- Technical features: Presents some technical data on each project;
- Links of interest: Includes a screenshot showing what the client looks like as well as links to useful pages and live demos.
How to choose the best Maps API?
So, which mapping framework should you choose? It depends on what features you need and how much you want to customize your map.
In this section, we will use 2 products as a basis for questions on how to choose a tool to work with maps. These are Google Maps and Leaflet JS – the most popular tools that reflect the 2 types of solutions to the question of choosing a tool for working with maps. Most users will be well served by simply choosing one of these two.
First of all, you need to start with a question – Do I Even Need A Mapping API? If you need something set up quickly, having no custom data or default map themes is OK for you – simply use an embedded map like the Bing one to the left. Google, Bing, and others offer options to embed a map.
Both of these choices (embedding or using a plugin) will meet only the most basic of mapping needs. If your use case fits within what they offer, then I encourage you to use them. When your mapping needs get more complex, you will need to switch to using an actual mapping framework.
If you choose a tool for maps apart from the technical classification, you will have to choose from Paid or Open-source solutions.
Both paid and open-source ones are good and reliable mapping APIs and there are a lot of good things they can do. Choosing between the two types will require consideration of several factors.
The Google Maps API is created and maintained by Google. All updates, improvements and rules regarding its use come from Google. All free tier implementations must be publicly available – intranet usage and maps behind a paywall require a premium plan.
Leaflet is an Open Source project, like WordPress, and there are fewer restrictions on its use. You can use it behind a paywall or on an intranet, use it for unlimited map views (though your base map provider may have its own limitations), remove or customize the branding and more.
Let’s move to the next question you will ask when choosing the solution for your business.
Releases and Upgrades
Since Google controls the Google Maps API, they determine the release schedule and when new features are added. They also determine when older versions of the code will be retired. For the most part it’s a good thing. It means most websites will be using the same version of the API and that developers using the Google Maps API will be familiar with exactly what options are available.
With Leaflet JS, upgrades are more frequent and incremental, and new releases are available as new features become available. The plugin updates are also independent of the map updates, so additional improvements may come through those channels too. Or, if you’ve got a Leaflet JS map you’re happy with, you can copy the map code to your own server and keep using an older version for as long as you want – you aren’t forced to upgrade.
Support Options
If you’re using the free tier of Google Maps, then you can check out their community support site. If you are a paid plan Google Maps API user, you will have other support options available to you, including a hotline you can call.
For Leaflet, there is active community support on StackExchange, StackOverflow and on GitHub, where the project code is hosted.
Best Mapping and Maps APIs
Some of these map APIs can really reduce the amount of effort needed to produce interactive maps. Many of these tools allow you to implement all kinds of dynamic maps with just a few lines of code.
Here are the mapping APIs you can use to show special map markers, draw custom route lines or even show a dialog when you hover or click on certain points of the map.
Personalize your maps in the style that you want – some of them can be styled with CSS – or customize your map to be as interactive as you like. The source of the map data, dependencies and licenses of each library have been included for your convenience.

Among the map types supported in Highmaps are choropleth and bubble maps. It is also possible to draw lines to depict a road, a river, or a connector. However, making flow maps is not as simple as with amMap or AnyMap, for example. It is also worth noting that neither Highcharts nor Highmaps can work without jQuery, so you must have this dependency if you want to use them or choose another charting library.
A good thing is that Highmaps offers multiple ready-to-use maps for both SVG and GeoJSON. The documentation is quite extensive and is great at helping you understand the library’s settings quite quickly and easily.

Pricing: Free
Map Data Source: OSM, Bing
Dependencies: None
License: SimpleGeo and Stamen copyright
Category: Library
Examples: http://polymaps.org/ex/
Polymaps is a free JavaScript library for creating dynamic and interactive maps. Besides the usual cartography from OpenStreetMap, CloudMade, Bing, etc., it works with image-based and vector-tiled maps by providing a quick display of multi-zoom datasets over maps and supports a variety of visual presentations.
Its main strength is making it very easy to composite raster and vector data from many different sources. It meets all your requirements, particularly in letting you easily add your own coloring, grouping and interaction. Polymaps is also quite efficient: it runs quickly and manages background tile loading well.
The nice thing about using SVG (scalable vector graphics) for creating maps is that it means that many of the same styling options which can be applied to web documents with CSS will also work with your map design.
Polymaps can load data at a full range of scales, and are a good fit for showing information from a country level on down to states, cities, neighborhoods and individual streets.
Mapael
Web-site: https://www.vincentbroute.fr/mapael/
GitHub stars: 1k, https://github.com/neveldo/jQuery-Mapael
Pricing: Free
Map Data Source: Raphael.js
Dependencies: jQuery
License: MIT License
Category: Library
Examples: https://www.vincentbroute.fr/mapael/
jQuery Mapael allows you to create maps with elegant data visualization as well as interactivity. You can, for example, create a map and designate each region on the map with different colors based on region. You can also add tooltip on the region, as well as event handlers like click or hover.
The map is built with SEO in mind by providing alternate content for search engine robots that are not capable of crawling JavaScript-generated content.
Mapael offers a collection of maps in its own repository. Documentation and API descriptions are combined in one article, but despite this you can easily get started with this library just by reading this detailed tutorial.
Conclusion
According to Google Trends 3, the most popular Mapping APIs are Leaflet JS, Google Maps API, and Mapbox. You can see a big gap in search queries with Bing Maps API and Openlayers; these are also quite popular.
All the free libraries we mentioned do a good job of building interactive maps. All the APIs are capable of producing great online mapping systems, but your choice should also fit in with you or your company’s future development needs.
For example, using any commercial API leaves you at the mercy of whatever changes the provider will make to the API or Terms of Service. On the other hand, using an open-source engine and the ability to switch providers anytime offers more freedom + flexibility, but it takes a lot of effort to build such systems.
We believe in using the right tool for the job. Leaflet and the Google Maps API will work well for most use cases, but there are situations that call for other tools.
For non-GIS background developers creating single-function mapping apps, we will recommend Leaflet (now supported by MapBox). It’s small and easy to use. More functionality relies on plugins of varying quality and support.
Lastly, if your maps are more design and user interaction oriented, you might want to consider using D3, a JavaScript animation library that can also do some types of mapping.
Thanks for reading this, and I do hope you find the article helpful.
