About

Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 42 KB of JS, it has all the mapping features most developers ever need. Leaflet is designed with simplicity, performance, and usability in mind. It works efficiently across all major desktop and mobile platforms, can be extended with lots of plugins, has a beautiful, easy-to-use, and well-documented API, and a simple, readable source code that is a joy to contribute to. Leaflet doesn't try to do everything for everyone. Instead, it focuses on making the basic things work perfectly. Hardware acceleration on mobile makes it feel as smooth as native apps. Utilizing CSS3 features to make panning and zooming really smooth. Smart polyline/polygon rendering with dynamic clipping and simplification makes it very fast. The modular build system for leaving out features you don't need. Tap delay elimination on mobile.

About

SurveyJS is an embeddable, self-hosted, white-label form builder for teams building custom forms, surveys, questionnaires, and other data collection tools inside web applications. It runs entirely on the client and is fully compatible with all modern JavaScript frameworks, including React, Angular, and Vue. SurveyJS integrates with any backend, giving you full control over data, security, user access, deployment, and business logic. Instead of hardcoding forms, you can empower non-technical users to generate and edit JSON schema-based form configurations through a drag-and-drop form builder. Create dynamic forms with custom conditional logic, validation, multilingual support, PDF export, and analytics. Ideal for SaaS, enterprise software, HR, healthcare, fintech, and other regulated industries, SurveyJS helps teams reduce engineering effort, standardize data collection, maintain full control over data, and deliver unlimited forms that match their brand and feel native to users.
