ZumiLabs OmniCapt

Local-first capture: screenshot one page or a whole sitemap at every size — record, annotate, compare. Nothing uploaded.

OmniCapt is a local-first browser capture tool for QA engineers, accessibility specialists, developers, agencies, and product teams. Capture a single page — or a whole sitemap — automatically across multiple screen sizes, then organise, search, compare, and share the results. Everything runs locally in your browser and files are saved to your own file system. Complete privacy.
