- [Visual editor bundle size benchmark, 2026](https://www.editorstack.cc/research/bundle-size-benchmark-2026) — We measured the JavaScript weight of twelve visual and rich-text editor libraries under identical conditions. Craft.js is the lightest at 29.2 kB gzip; TinyMCE is the heaviest at 393.9 kB, a 13.5× spread across libraries that are routinely compared with each other.
- [The visual editor library ecosystem in 2026: what our dataset tells us](https://www.editorstack.cc/research/editor-library-ecosystem-report) — An analysis of our own dataset: how these products are licensed, how they meter, what they all refuse to do, and the four structural patterns that explain most purchasing regret in this category.
- [State of Visual Builders 2026: survey open, results not yet published](https://www.editorstack.cc/research/state-of-visual-builders-2026) — We are collecting data on how development teams choose and live with visual editor libraries. No results are published here yet, because we have not run the survey — this page is the invitation, not the report.
- [Time to first editor: how long eight visual editors take to appear](https://www.editorstack.cc/research/time-to-first-editor-benchmark) — We built the same minimal editor eight times and measured it: Editor.js reaches a rendered editor in 70 ms and 5 lines of code, React Page takes 1,004 ms and needs a bundler alias to build at all against React 19.
