Roadmap 2021

[lo5]

This is a living document. Check back for updates!

Goal

H2O Wave aims to be the quickest way to build beautiful, realtime, high-performance web apps and dashboards entirely in Python (and soon R) without using HTML, Javascript, or CSS.

Our roadmap this year focuses on production-readiness, ease of use, expanding our palette of cards/components, better integration with third-party libraries, and R language support.

The initiatives marked 🔬 require us to have a better understanding of the problem and potential solutions before committing to actual feature work. We continuously tune the plan based on research, feedback, and lessons learned from shipping each release.
