Comparador

Comparador is a tool for on-demand visual regression testing — compare web pages across environments, track changes over time, debug deployment issues. Easy: Install → Capture → Compare. No pipelines. No accounts. No external servers. Key features: 📸 Visual Diff: Full-page screenshots with pixel-level comparison, mismatch %, multiple view modes 📄 HTML Diff: Side-by-side source comparison with syntax highlighting 📋 Headers Diff: Compare response headers (cache, CDN, security) 🪵 Logs Diff: Compare console logs — spot new errors, warnings, count changes 📊 Metrics Diff: Track 20 performance indicators (TTFB, DOM load, JS heap) with threshold-based verdicts ✅ Baselines: Accept/reject workflow with automatic + manual baseline control 🔄 Auto Compare: Automatic comparison against baselines after capture with auto-accept 🚀 Batch Capture: Capture projects or groups of URLs, compare across environments 🤝 Team Sync — share project setup with your team via export/import files, or auto-sync via Git/GitHub — no cloud account needed ⚡ Popup: Quick environment switching + fast access to frequently tested pages Changelog: 1.5.5 • Link detail panel: click "…" next to a navigation link to pick options as chips, preview the exact URL live, then Open it or Update the current page • Popup opens on the link for the page you're on, so the likely next step is one click away • Options already in effect are read from the current URL and shown as selected • Only relevant options are shown. Options that don't apply are hidden and never added to the URL, and your picks come back when you switch back • Fewer broken links: "Open on" appears only on real content pages, with plain Browse links everywhere else • Clear error messages when a navigation script returns something unexpected AEM (Adobe Experience Manager): • Choose how to open a page: Editor, Sites console, CRX/DE or the plain page on Author, and the plain page or CRX/DE on Publish • WCM mode, clientlib debug and ?debug=true are offered only where AEM honors them • CRX/DE is hidden on AEM as a Cloud Service • Sites, Assets and CRX/DE open at your content or DAM root • Tool pages (CRX/DE, consoles, /system) are no longer mistaken for site pages • Unified Shell /ui URLs are handled automatically Existing projects and navigation scripts keep working. To get the new AEM views, reload the AEM templates in the project editor. 1.5.2 · Popup welcome screen — added quick access to import existing projects 1.5.1 · Page readiness steps — the default Page script can now wait for configured globals, flags, and synchronous or asynchronous ready functions before preparing the DOM, improving capture stability for complex applications and SPAs · Script testing — Setup and Navigation scripts can now be tested directly from the project editor using the current unsaved script and variables, with returned data shown before anything is applied · Expanded Automation and Capture documentation with readiness configuration, debugging guidance, and script-testing workflows 1.5.0 · Popup navigation — clearer, more reliable navigation across project structures and environments · Per-link options — URL variants and query parameters are now scoped to individual links, preventing invalid combinations and making the final URL easier to preview AEM (Adobe Experience Manager): · AEM navigation and setup — improved support for Author, Publish, Live/CDN, and local environments 1.4.7 · Popup bug fixes 1.4.5 · Historical comparisons — capture "compared with" badges and "View comparison" links now stay more accurate even after the baseline changes later 1.4.4 General changes: · Group compare button — Manage view for a group now has a Compare button (previously only available on captures/attempts), comparing the group's baseline capture against its latest · Popup action menu — replaced the right-click trigger (which could close the popup before the menu opened) with a compact left-click button next to each navigation link · Added a Known Issues section to the documentation, covering a macOS Chrome popup-latency bug and expectations around cross-machine screenshot differences · Bug fixes and stability improvements AEM-related (Adobe Experience Manager): · Comparison defaults — HTML diff normalization now ships with working AEMaaCS clientlib cache-bust hash handling, Core Components data layer noise removal (repo:id, repo:modifyDate), and adaptive image (coreimg) rendition timestamp normalization, so cross-environment AEM diffs no longer flag pure infrastructure noise as changes · Opt-in environment host normalization — documented replacePatterns examples for normalizing direct AEMaaCS Author/Publish hosts or public dispatcher/CDN domains that differ per environment, for projects without a shared public domain in front · Navigation script fixes — corrected jump links for AEMaaCS's unified shell editor URLs (/ui#/aem/editor.html/...), CRX/DE links with query suffixes, and pages with no resolvable content path — cross-environment and Author/Publish jumps now resolve correctly in every case · Improved consistency between generic and AEM project variable presets — capture and comparison override examples now documented in both 1.4.2 · Project sync — safer handling of changes when synchronizing projects · Removal policies — choose how removed project data is handled during sync · Documented capture and automation timeouts · Updated footer branding and links 1.4.1 · Project sync — share project configuration (URLs, settings, scripts, variables) with your team via GitHub, any Git remote (Bitbucket, GitLab, Gitea, self-hosted), or a local/shared folder. Push and pull explicitly, or set a Pull mode to check and pull automatically · Pull mode — choose how eagerly Comparador checks for remote changes: manual only, always, or every 5/15/60 minutes · Sync status is based on comparing actual content, not timestamps, so it stays accurate across providers and reconnects · Comments in your…
