RenderLog
RenderLog helps teams capture screenshots, export web pages, run visual tests, and monitor websites without managing Playwright infrastructure.
About RenderLog
RenderLog is a web testing and capture service that runs pages in a real browser and compares results against an approved baseline. It combines a screenshot and rendering API with saved no-code web tests, so the same run can produce screenshots, PDF, HTML, Markdown, files or video alongside visual diffs and content or form-state assertions.
Users create a workspace, define URLs, selectors and viewports, and tune rendering with headers, cookies, waits, blocked requests and device presets. A baseline is locked as the accepted state, and later runs are compared against it. Checks can be started manually, through the API, from CI or on a schedule, with notifications sent to Slack, Teams or a webhook. Result files, logs, labels and review decisions stay attached to the run history, and non-document runs include Web Vitals.
The site describes use by product teams reviewing UI after releases, marketing teams catching broken CTAs or pricing edits, agencies keeping visual records of client sites, and content teams verifying headings, copy and structure after CMS edits.
