Records screen, webcam, and microphone while capturing console logs, network requests, and user actions in sync for reproducible bug reports. Lumrec – Screen Recorder & Bug Reporter comes from Sazae Technology as a Chrome extension and desktop companion, offering instant share links, annotated screenshots, and time-stamped collaboration. It targets developers, QA engineers, product managers, and support teams who need visual evidence paired with technical context to accelerate debugging and documentation workflows.

How it captures technical context to reproduce issues

Lumrec records runtime traces alongside video, aligning console errors, network requests and responses, and recorded user actions with playback so a developer can see the exact sequence that caused a fault. The tool captures browser environment details as part of each bug report, and the synchronized DevTools view shows logs in time with the recording, which supports faster reproduction than text-only reports.

Privacy controls and automatic redaction protect sensitive fields

Automatic redaction removes sensitive inputs before upload, filtering passwords, card fields, one-time codes, and sensitive headers as part of the reporting flow. The extension includes screenshot annotation (arrows, text, blur) for manual masking, and the upload process applies redaction rules so captured recordings omit protected values before they are stored.

Workflow integration, collaboration, and platform availability

The extension fits team workflows that share and comment on recordings by producing instant shareable links and supporting time-stamped comments and reactions on captures. It runs as a Chrome extension compatible with Chromium-based browsers and also offers desktop apps for macOS, Windows, and Ubuntu for global shortcuts and advanced recording. An account is required to upload and host reports, which centralizes storage for team access.

Clear technical value for teams, tempered by hosted-account dependency

Lumrec suits technical teams that need video paired with runtime diagnostics to shorten reproduce-debug cycles; its synchronized logs and sharing model make defect triage more actionable. The dependence on an account to upload and store reports introduces a hosting step that teams must accept or manage centrally. For teams willing to centralize recordings, Lumrec brings a focused reporting workflow that reduces back-and-forth between reporters and engineers.
