0 Day Analytics vs SlimStat Analytics

0 Day Analytics is a comprehensive WordPress debugging and operational intelligence plugin. It is purpose-built for developers and site administrators who need real-time visibility into their PHP errors, scheduled tasks, database state, outgoing emails, HTTP requests, hook behaviour, and overall site health — all from a single admin interface. Unlike general monitoring services, 0 Day Analytics runs entirely inside your WordPress installation with no third-party data collection. Every module is opt-in and designed with performance in mind. Plugin Website: 0-day-analytics.com User Documentation: User Guide Dashboard A centralised overview page providing at-a-glance status for all active plugin modules. Displays real-time widgets for Error Log, Fatal Errors, Cron Jobs, Transients, HTTP Requests, WP Mail, REST API, and Security — each showing key metrics and recent events. Toggle individual module widgets on or off. The Dashboard is the default landing page when clicking the main plugin menu item, giving administrators immediate visibility into site health and activity without navigating to each module separately. Error Log Manager Read, search, filter, and manage your PHP/WordPress error log without leaving the admin. Engineered for very large (GB-sized) logs using a reverse-line reader that never performs a full-file read. Supports code-context viewing (click any error to see the surrounding source), per-severity filtering, log truncation, and download. Optionally randomise the log filename to reduce exposure. PHP Fatal Error Tracker Captures and stores PHP fatal errors in a dedicated database table, it records PHP errors even if the WP_DEBUG is turned off so they persist even after the log is rotated or overwritten. Each record includes error type, file, line, stack trace, and timestamp — searchable and filterable directly in the admin. Site Performance & Security Scanner Runs 32+ automated checks across three categories — Security, Speed, and Resources used — and presents a scored dashboard with actionable recommendations. Checks include: PHP version, WordPress version, SSL certificate, debug mode exposure, file permissions, database prefix, XML-RPC, login URL, active plugin count, autoloaded options, cron health, page caching, object caching, gzip compression, lazy loading, image optimisation, and more. Google PageSpeed & Core Web Vitals Analyse any URL directly from the WordPress admin using the Google PageSpeed Insights API. Displays Performance, Accessibility, Best Practices, and SEO scores with Lighthouse category breakdowns for both desktop and mobile. For that you need to provide your own PageSpeed Google API key. URL Tracker & Asset Analyser Automatically tracks visited page URLs on your site. For each recorded URL, you can collect all associated JS, CSS, and media assets (with file sizes), run a Google PageSpeed analysis, and review visit counts — making it easy to audit page weight and performance regressions over time. Cron Manager View, search, edit, manually run, and delete WordPress scheduled tasks. Shows next run time (UTC), recurrence interval, arguments, and last execution status. Supports bulk actions and advanced filtering. Transients Manager Browse, search, edit, and safely delete database transients. Displays expiry time, serialised value (pretty-printed), and size. Bulk delete supports filtered selections. Outgoing HTTP Requests Viewer Logs all outgoing wp_remote_* calls made by WordPress core, themes, and plugins. Records URL, method, status code, response time, triggering plugin, user, and full request/response detail. Export to CSV for external analysis. Advanced filtering by domain, plugin, status, and date range. Mail Logger & Composer Records every email sent through wp_mail() — including headers, body, attachments, CC, and BCC — and stores it in a searchable log. View the rendered email body, resend any logged email, or compose and send new emails directly from the admin. Supports HTML and plain-text previews. SMTP Configuration Configure custom SMTP settings (host, port, encryption, username, password) with a built-in test email tool. Optionally log SMTP debug output to the WordPress debug log. WP Hooks Monitor Define which WordPress actions and filters (core or custom) you want to observe. The Hooks Capture module records each invocation with its parameters, return value (for filters), and a full stack backtrace. Organise monitoring rules into named groups, enable/disable per hook, and review the captured output in a dedicated list view. DB Table Manager Browse, search, edit, and delete records across any table in your WordPress database — including custom plugin tables. Displays table size, engine, collation, row count, and schema information. Supports full and filtered truncation and table drop with confirmation. Server Info & System Status Displays real-time server metrics (CPU load, memory usage, disk space, PHP version, active extensions) as both admin-bar badges and a dashboard widget. Also provides a detailed environment report useful for support tickets and deployment checks. Plugin Version Switcher Roll back or switch between any previously downloaded version of an installed plugin without leaving the admin. Useful for quickly reverting after a bad update. Supports only free plugins from the WordPress repo. Code Snippets Write, save, and execute custom PHP snippets from the admin. Snippets support shortcodes, can be enabled/disabled individually, and are sandboxed before execution. Useful for one-off data migrations, testing custom logic, or generating dynamic output without creating a custom plugin. REST API Manager A security and management tool that gives full visibility and control over every registered REST API endpoint (/wp-json/). Inspect all registered routes, disable individual endpoints, restrict HTTP methods, and hide routes from discovery responses. Useful for hardening your site by removing unnecessary API surface area. WP Panel A centralised control panel for toggling WordPress core features and settings. Enable or disable comments, revisions, auto-updates, XML-RPC, the REST API, emojis, embeds, heartbeat behaviour, frontend asset loading, and more — all from a single, organised admin page. No code changes or custom snippets required. Traffic Analytics Privacy-focused website traffic monitoring built directly into WordPress — no external services or third-party scripts. Tracks unique visitors, pageviews, top pages, referrers, and technology breakdown (devices, browsers, operating systems) with a visual SVG-based dashboard. Choose between server-side (PHP) or client-side (JavaScript) tracking. Includes real-time visitor count automatic period comparison, configurable data retention, and a high-performance file-based write buffer. Important: By default, Traffic Analytics uses server-side (PHP) tracking mode. This method is less accurate because it cannot distinguish bots from real visitors as effectively and may miss visitors served from full-page caches. If you need more precise analytics, switch to client-side (JavaScript) tracking in the module settings — this mode runs a lightweight script in the browser that provides significantly more accurate visitor detection and pageview counting. Security Monitor Real-time security event monitoring and threat detection for your WordPress site. Tracks brute-force login attempts, burst rate limiting (DoS protection), user enumeration attempts, and blocked requests. Displays a summary dashboard with total events, critical alerts, blocked requests, and active incidents over the last 7 days. Includes an Emergency Lockdown button to immediately restrict site access during an active attack. Events are logged with severity level, IP hash (privacy-preserving), attempt counts, and detailed request information. Login & Auth Audit Comprehensive authentication event logging that tracks all login activity on your site. Records successful logins, failed login attempts, session expirations, and password resets with full context — including user, IP hash, user agent, and timestamp. Displays summary statistics (total events, successful logins, failed logins, password resets) for the last 7 days. Supports filtering by event type and severity, search, and CSV export. Recovery Mode Generate single-use recovery links that can disable a specific plugin or trigger a custom action — delivered via Slack, Telegram, or any configured webhook channel. Designed for emergency recovery when the site is inaccessible through normal means. The recovery URLs are sent in Slack and Telegram channels for security. Other Features Dark mode for all admin screens. CSV export on all list views (requests, errors, mails, hooks, etc.). Screen Options on every screen (configure columns, items per page). WP CLI compatible scaffolding for background operations. Multisite aware (note: recovery mode has core multisite limitations). Requirements & Compatibility WordPress 6.0+ (tested up to 6.9) PHP 7.4+ (compatible with PHP 8.0, 8.1, 8.2, 8.3, 8.4, 8.5) MySQL 5.7+ / MariaDB 10.3+ Not intended as a primary multisite recovery tool (see FAQ) Best Practices & Security Notes Keep log files outside the webroot when possible, or restrict access via server rules (.htaccess / nginx) to prevent public exposure. Use the built-in “Randomise Log Filename” feature when logs must stay in the webroot. All plugin capabilities are restricted to manage_options (administrators) by default. The menu can optionally be restricted to admins only. Sanitize and escape all output; nonces are enforced on all state-changing actions. Secure SMTP credentials using TLS/STARTTLS; credentials are stored in the WordPress options table. Set file permissions tightly (e.g., 600/640) and restrict ownership to the web server user. Backup database and files before using bulk delete or table truncation. Disable unused modules to reduce footprint and potential attack surface. Disable or throttle high-frequency background polling on high-load sites. Usage Notes & Performance The Error Log viewer reads the last N lines (default 100, max configurable via Screen Options) to avoid full-file reads on GB-sized logs. No pagination on error logs by design — pagination would force repeated expensive full-file reads. The PHP Fatal Error Tracker uses its own DB table; apply a retention policy in Settings to avoid unbounded growth. The Hooks Capture module adds minimal overhead per captured hook invocation; disable capturing on production when not actively debugging. The URL Tracker records page visits in a custom table; configure retention or pause tracking on high-traffic sites. Support & Notes Secure log paths and consider randomising filenames in production. Disable unused modules to reduce footprint and attack surface. Recovery Mode has limitations on multisite — test before relying on it. For bugs or feature requests, open an issue on the plugin page.

Most analytics plugins quietly hand your visitors to someone else’s cloud. SlimStat doesn’t. Every pageview, click, and visitor lands in your own WordPress database and stays there: yours to read in real time, yours to purge whenever you want, never shipped off to Google or anyone else. See the whole story the moment it happens: who’s on your site right now, where they are in the world, what they’re reading, and which links they follow on the way out. Set a goal and watch it convert, or chain a few steps into a WooCommerce funnel and see exactly where people slip away. It’s the depth you’d expect from a hosted analytics service, running entirely on your own terms. Best part: privacy isn’t a setting you have to hunt for. Anonymized IPs, Do Not Track, a consent banner, and scheduled data cleanup are GDPR-ready from the first activation. Thousands of WordPress sites already trust SlimStat to keep their analytics honest, fast, and entirely their own. Main Features Real-time access log — Your site’s pulse, live. Watch each visit land the instant it happens: the page, the spot on the map, the search or link that sent them, how quickly your server replied, human or bot. Complete access log — Every visit in one searchable table. Drill into the full history and break it down by date, country, browser, OS, referrer, search term, or content type to answer the questions the summary charts can’t. Goals & funnels — Turn raw traffic into answers. Define a goal to measure a conversion (a WooCommerce sale, a signup, a key pageview) and see uniques, totals, and conversion rate. Or chain steps into a funnel to spot exactly where visitors drop off. One goal is free; up to five goals and full funnels unlock with Pro. Outbound link report — See which external links actually earn clicks. SlimStat records every outbound link your visitors follow, so you know what’s sending traffic off your site and which partnerships pull their weight. Know your visitors — Go past pageviews to the people behind them: returning readers, logged-in users, and a full audience breakdown by country, language, browser, OS, and screen size. (Pro’s User Overview adds per-visitor journeys, time on site, and Gravatars.) Your data, your server — No third-party cloud, no Google looking over your shoulder. Every byte lives in your WordPress database, and one-way IP hashing lets you count unique visitors without ever storing who they are. GDPR, sorted — Anonymize or hash IPs, honor Do Not Track, auto-purge old records on a schedule, and drop in a translatable consent banner that snaps straight into the WP Consent API (WPML and Polylang welcome). Compliance by design, not an afterthought. Admin bar stats — Keep an eye on the numbers without leaving your work. Online visitors, pageviews, and top pages sit one glance away in the WordPress admin bar, on every screen. Make every report yours — Rearrange, add, or hide widgets across Real-Time, Overview, Audience, Site Analysis, and Traffic Sources until each screen shows exactly what you care about. Shortcodes — Drop any report into a widget, post, or page with a single shortcode. Filters — Decide who counts. Skip your own team, known bots, whole IP ranges, admin pages, or entire countries so your stats reflect real visitors, not noise. Geolocation — Put a city and country to every visitor, plus their browser and operating system, powered by MaxMind and Browscap. World map — Watch your audience light up across the globe at a glance, even from your phone (map by JQVMap). Export & email — Download your reports as CSV files, generate user heatmaps, or get the day’s numbers in your inbox each morning (heatmaps and email reports via Pro). Cache-friendly — Plays nicely with W3 Total Cache, WP Super Cache, Cloudflare, and most caching plugins. Pro Pack Features Love the free plugin? Pro is for sites that live by their numbers. It adds the heavier tools without changing a thing about how SlimStat respects your data: Email reports — Wake up to the numbers that matter. Schedule the reports you care about and have them land in your inbox as clean HTML tables, with the columns laid out your way. Heatmaps — See exactly where visitors click, and where they don’t, with a heatmap layer painted right over your live pages. User overview — Follow individual registered users: what they viewed, how long they stayed, and how fast your server answered, with Gravatars to put a face to the visit. Extended overview — Add your own columns to the User Overview report and export file, so it tracks exactly what your site cares about. More goals & funnels — Up to five conversion goals and three full funnels, with ready-made templates for WooCommerce checkout, signups, and content engagement. Network analytics — Run reports and settings across an entire multisite network from one place. MaxMind integration — Connect MaxMind’s geolocation API for richer, more precise detail on where your visitors come from. Custom database — Store all your analytics in a separate, external database to keep your main WordPress DB lean. Export to Excel — Download any report as a ready-to-share Excel file. Requirements WordPress 5.6+ PHP 7.4+ MySQL 5.0.3+ At least 5 MB of free web space (240 MB if you plan on using the external libraries for geolocation and browser detection) At least 10 MB of free DB space At least 32 Mb of free PHP memory for the tracker (peak memory usage) Please note If you decide to uninstall Slimstat Analytics, all the stats will be PERMANENTLY deleted from your database. Make sure to setup a database backup (wp_slim_*) to avoid losing your data. Report Bugs Having trouble with a bug? Please create an issue on GitHub.
