+description: You can now use local development with Browser Rendering

+You can now test your Browser Rendering apps locally before deploying using `npx wrangler dev`. Local development support makes it easier to develop, debug, and iterate before deploying to Cloudflare's global network.
+
+Get started with this [example guide](/browser-rendering/workers-bindings/screenshots/) that shows how to use Cloudflare's [fork of Puppeteer](/browser-rendering/platform/puppeteer/) to take screenshots of webpages and store the results in [Workers KV](/kv/).
