Detect 250+ bots hitting your website
Your server logs contain every bot visit — search engines, AI crawlers, SEO tools, scrapers, security scanners, and monitoring services. LogBeast identifies them all by name, categorizes them, and shows you exactly what they're doing on your site.
Why bot detection from server logs matters
Google Analytics and similar tools only show you human traffic. They completely miss bots — and bots often account for 40–60% of your total server traffic. Without analyzing server logs, you're blind to more than half of what's happening on your website.
Bad bots scrape your content, hammer your server, waste your crawl budget, and probe for vulnerabilities. Good bots — like Googlebot — determine whether your pages appear in search results. AI crawlers like GPTBot are training models on your content right now. You need to know who's visiting, how often, and what they're requesting.
10 categories, 250+ named signatures
LogBeast doesn't just detect "bot traffic." It identifies individual bots by name using a database of 250+ user agent signatures, grouped into 10 categories with 36 dedicated analysis tabs.
Search Engine Crawlers
See exactly how search engines crawl your site: which pages, how often, response codes, crawl depth, and time spent. Includes Googlebot, Bingbot, Yandex, Baidu, DuckDuckBot, Ecosia, Qwant, Naver, Seznam, Sogou, Mojeek, CocCoc and more.
AI & LLM Crawlers
The fastest-growing category. Track GPTBot (OpenAI), ClaudeBot (Anthropic), Google-Extended / Gemini, PerplexityBot, Grok (xAI), DeepSeek, Bytespider, Cohere, PetalBot, Meta AI, YouBot and more. Learn more about AI crawler tracking →
SEO Tools
See which SEO tools are crawling your site and how aggressively. Ahrefs, Semrush, Moz, Screaming Frog, Majestic, SISTRIX, ContentKing, and dozens more.
Security Scanners
Detect vulnerability scanners probing your site: Nuclei, WPScan, Burp Suite, DirBuster, Nikto, and 25+ more. Know when someone is actively looking for weaknesses. Learn more about security analysis →
Monitoring Services
Identify monitoring bots from Uptime Robot, Pingdom, Zabbix, New Relic, Datadog, Site24x7, StatusCake, and more. See how much traffic your own monitoring tools generate.
Social Media Bots
When someone shares your URL on social media, platform bots fetch your page to generate link previews. Track Facebook, Twitter/X, LinkedIn, Pinterest, Slack, Discord, Telegram, and more.
Scrapers & Headless Browsers
Detect automated scraping tools: Puppeteer, Selenium, Scrapy, HTTrack, Wget, curl-based scrapers, and headless Chrome/Firefox instances. See which pages they target most.
Dedicated Bot Tabs
Every major bot gets its own analysis tab showing crawl frequency, pages visited, response codes received, resources requested (CSS, JS, images), and activity over time.
What you learn from bot analysis
Crawl budget waste
Googlebot has a limited crawl budget for your site. If it spends 60% of its visits on paginated archives, faceted navigation, or parameter URLs, your important content pages get crawled less often. LogBeast shows you exactly where Googlebot wastes time so you can redirect that budget to pages that matter. More on SEO log analysis →
Fake bot detection
Some bots claim to be Googlebot but aren't. They spoof the user agent string to bypass access controls. LogBeast flags suspicious bot claims by cross-referencing IP ranges with known bot networks — helping you distinguish real crawlers from impersonators.
AI content harvesting
AI crawlers are scraping the web to train large language models. LogBeast tracks 25+ AI crawler signatures so you can see exactly how much of your content is being consumed by GPTBot, ClaudeBot, and others — and make informed decisions about your robots.txt directives. More on AI crawler tracking →
Attack reconnaissance
Security scanners like Nuclei and DirBuster often precede actual attacks. Detecting scanner activity early gives you time to harden defenses. LogBeast identifies 30+ scanner signatures and highlights suspicious IP addresses. More on security log analysis →
Resource consumption
Bots don't just request HTML pages. They fetch CSS, JavaScript, images, fonts, and API endpoints. LogBeast breaks down exactly what resources each bot category consumes, so you can see which bots are costing you the most bandwidth and server load.
DNS-based bot verification
Anyone can put "Googlebot" in their user agent string. LogBeast goes beyond user agent matching: it checks whether bot IPs actually resolve to the domains they claim to represent. This is how you catch fake Googlebots, fake Bingbots, and other impersonators that use spoofed user agents to bypass your rate limiting or access controls.
How it works
Drop your Apache or Nginx access log into LogBeast. Within seconds, every request is parsed, every user agent is matched against 250+ signatures, and you get a complete picture of your bot traffic — broken down by category, by individual bot, by page, by time period.
- Automatic log format detection (Apache Combined, Common, Nginx, IIS, CloudFront, Cloudflare)
- 250+ named bot signatures matched by user agent pattern
- 36 individual bot analysis tabs for major crawlers
- Bot vs. human traffic split with trend analysis
- Per-bot crawl frequency, pages visited, response codes, bandwidth consumed
- Resource breakdown: HTML, CSS, JS, images, fonts, API calls per bot
- DNS verification for bot identity claims
- CSV export of all bot data for further analysis
Everything runs in your browser. Your log files never leave your machine. No server uploads, no cloud processing, no data sharing. 100% client-side log parsing.
Frequently asked questions
How does LogBeast detect bots?
LogBeast matches the user agent string from each log entry against a database of 250+ known bot signatures. It uses pattern matching to identify bots even when they use variant user agent strings. For critical bots like Googlebot and Bingbot, it also cross-references IP addresses against known bot IP ranges for verification.
Can it detect bots that don't identify themselves?
Some bots use generic or empty user agent strings. LogBeast flags these as "unknown" and provides behavioral analysis — request patterns, hit frequency, pages visited — to help you identify whether they're legitimate traffic or disguised crawlers.
What log formats are supported?
Apache Combined Log Format, Apache Common Log Format, Nginx default, IIS, Amazon CloudFront, and Cloudflare. LogBeast auto-detects the format — just drag and drop your file. See Apache log analysis and Nginx log analysis for format-specific details.
Is my data safe?
Yes. LogBeast runs 100% in your browser. Your log files are never uploaded to any server. All processing happens locally on your machine. No analytics, no tracking, no data collection.
How many log lines can it handle?
LogBeast uses chunked processing and single-pass algorithms optimized for browser performance. It routinely handles 1M+ log lines. For very large files (10M+), processing may take a few minutes depending on your hardware.
