• What’s new in the Grafana Image Renderer: higher-quality results, security enhancements, and more Whether it’s for an email or that upcoming presentation, many Grafana users like to share their favorite dashboards or panels outside of Grafana itself. • The Grafana Image Renderer is a backend service for Grafana that helps you do just that by rendering panels and dashboards as images, such as PNGs and PDFs, via a headless browser. • It’s commonly used to support Grafana features like exporting dashboards, generating images for alert notifications, and creating PDF reports. • Earlier this year, we started working towards improving the Grafana Image Renderer, with the overall goal of enhancing the service’s performance, reliability, and security. • Recently, these efforts resulted in the v5.0 release, which involved a whole rewrite of the service and included significant security improvements for our Grafana Cloud users. • What is the Grafana Image Renderer?
Article Summaries:
- Grafana has released version 5.0 of its Image Renderer service, a rewrite that improves performance, reliability, and security. The update adds new heuristics that wait for all network requests, data‑source queries, and DOM changes to stabilize before capturing a panel, reducing blank or incomplete renders in PDFs and alert images. Security hardening focuses on the Chromium engine the renderer uses, addressing previously identified vulnerabilities. The plugin form of the renderer was deprecated in September 2025, so the service now exists only as a standalone deployment alongside Grafana OSS, Enterprise, and Cloud. These changes aim to deliver higher‑quality exported images and a more secure rendering pipeline.
