LogLens

Overview

LogLens verifies claimed bots against providers’ published IP ranges and covers more than 200 bots. It connects live crawler activity with sitemaps, Google Search Console data, and robots.txt changes, helping teams interpret crawl behavior alongside the signals that guide it. Security monitoring adds detectors for automated hacking probes, bot impersonation surges, and secrets exposed in URLs.

The service describes 16 anomaly detectors, with alerts identifying affected IPs, paths, and crawlers. Alert timing is a meaningful tier difference: hourly on Free, every 30 minutes on Solo, and every five minutes on Starter and above. Free and Solo can suit monitoring where immediate notification is not essential; teams relying on faster response should start at Starter.

Key features

Live sources and imported logs

Real-time sources include Cloudflare, AWS CloudFront, Vercel, Kinsta, Shopify, Apache, and Nginx. Users can also upload Apache, Nginx, CloudFront, or Events CSV logs, and those imports do not count toward the monthly request quota. That makes historical or one-off log review less costly in quota terms, though ongoing real-time ingestion remains subject to plan limits.

SEO and security context

By combining crawler verification with sitemap, Search Console, and robots.txt signals, LogLens offers a useful view for teams investigating crawl patterns rather than merely counting requests. Its security detectors broaden the tool’s relevance, particularly for SEO teams watching bot impersonation or exposed URL secrets. Data is stored in AWS eu-west-2 (London), encrypted at rest and in transit, and not sold or aggregated across customers; a DPA is available on request.

Pricing

The Free plan costs 0.00 USD per free, billed $0/month. It allows 500K requests per month on one website, retains 30 days of history, and includes real-time analytics, bot and AI crawler detection, and 10 AI answers per month. Hourly alerts and the low request cap make it a sensible starting point for a small site or initial evaluation, not a strong fit for frequent operational monitoring.

Solo costs 19.00 USD per month, billed $19/month or $190/year — save 20%. It raises the quota to 5M requests per month and history to six months, with one website (up to three at +$10/mo each), sitemap and GSC integration, email and Slack alerts, CSV export, and unlimited users. Its 30-minute alert cadence is the key compromise for teams that need faster response.

Starter costs 49.00 USD per month, billed $49/month or $490/year — save 20%. It includes 20M requests per month, five websites (up to 10 at +$10/mo each), one year of history, a public API, webhook integrations, and unlimited users. Five-minute alerts make it the more practical entry point for teams that need timely notifications or programmatic access.

Growth costs 149.00 USD per month, billed $149/month or $1,490/year — save 20%. It offers 100M requests per month, 15 websites (up to 30 at +$10/mo each), two years of history, priority support, and unlimited users. It suits agencies or larger teams managing multiple properties that can use the added quota and longer retention.

Pro costs 499.00 USD per month, billed $499/month or $4,990/year — save 20%. Its 500M monthly requests, 50 websites plus unlimited extras at $10/mo each, four years of history, dedicated support, and unlimited users target high-volume operations. Enterprise has custom pricing for 500M+ requests, with custom request volume and retention, unlimited everything, SSO/SAML, DPA and custom MSA, uptime SLA, and a dedicated CSM and Slack.

All paid plans have opt-in overage protection with a user-set cap at $2 per extra million requests. Without opting in, real-time ingestion pauses at quota, though alerting continues. The 14-day full-access trial requires no credit card; after it expires, data remains for seven more days before deletion unless the account is claimed.

Platforms

LogLens supports API, self-hosted, and web use. The combination of live sources and file uploads gives teams more than one route for bringing access logs into analysis.

Who it's for

The strongest fit is technical SEO teams, SEO agencies, AI-GEO specialists, developers and DevOps leads, ecommerce managers, and security-conscious SEO teams. Its crawler verification and SEO correlations are especially relevant to teams diagnosing search-bot behavior, while the security detectors add value for teams that also watch suspicious request patterns. A reader who needs only occasional, small-scale log review may prefer a free or locally run alternative.

Pros and cons

• Pros: Verification against published IP ranges across more than 200 bots adds context to crawler analysis.
• Pros: Imports do not consume monthly request quota, and alerts can identify affected IPs, paths, and crawlers.
• Pros: Unlimited users on paid plans avoid per-seat limits as teams grow.
• Cons: Free is capped at 500K requests monthly, one website, and hourly alerts, limiting its usefulness for larger or time-sensitive monitoring.
• Cons: Solo’s 30-minute alert cadence is slower than Starter and above, so the lower price comes with a response-time trade-off.
• Cons: Overages require opt-in protection; otherwise real-time ingestion pauses when the quota is reached.

Verdict

LogLens is a strong choice for teams that want verified crawler analysis tied to SEO and security signals, especially when they can use its live-source integrations and quota-free imports. Choose it if the request allowance, retention, and alert cadence of the relevant tier match your workload. Look elsewhere if you need a locally run free analyzer or if LogLens’s tiered quotas and slower lower-plan alerts do not suit your monitoring needs.
