detector.io scrapers compared

376 tools that scrape detector.io, ranked by real usage over the last 30 days. Success rate is the share of public runs that finished successfully in the last 30 days. Summed reported actor users: 719. Users may overlap across tools; this is not a count of unique people or buyers, or search volume.

At a glance: 376 tools; 57 of 60 displayed tools have recorded 30-day run completion (20+ public runs); the current usage pick accounts for 6% of all reported users. Dataset file date: 2026-10-21; individual observation dates vary or are unknown.

Carried forward means retained from an earlier fetch; pricing and usage may have changed, or the listing may be absent from today's fetch. Unknown observation dates remain unknown. Dataset file dates and tool build dates are not tool observation dates.

Most used: Website Technology Stack Detector (BuiltWith Alternative) (40 users in 30 days).

Most reliable with 300+ runs: Instagram Bot Detector (99.9% of 1,500 runs succeeded).

Current recommendations use only tools fetched in this dataset with a known observation date. Carried-forward and unknown-date records remain in comparisons but cannot be current picks.

Pricing coverage among 60 displayed tools: 57 with a recorded primary-event rate; 1 with an unavailable primary-event rate; 2 with an explicit FREE model. Primary-event rates use the recorded billing units below; different events are not equivalent results.

Comparison evidence

Sorting covers only the displayed subset (at most 60 tools), not the entire store or every matching actor. Success means run completion, not output accuracy. Review sorting uses review count, not rating. Unknown evidence stays last; ties retain original order.

Download the detector.io comparison CSV (60 displayed tools). Includes snapshot_date (the dataset file date, not tool observation), observed_on (blank when unknown), observation_status (fetched, carried_forward or unknown), carried_forward, usage, recorded runs and reviews (blank when unavailable; 0 means recorded zero), success rate (0–1), pricing model, primary event and its listed USD price per 1,000 events (per_k). This primary-event rate is not total cost: run-start and additional charges may apply, and events can differ between tools. Unknown prices and success rates are blank; FREE identifies an explicit free pricing model.

Success rate is shown only for tools with 20+ runs in 30 days; below 90% is highlighted. Prices are list prices for Apify's free plan (paid plans are cheaper). Rates are per 1,000 primary events in the recorded unit named beside each rate; an unavailable billing unit is labeled explicitly. Different billing events do not imply equivalent results. Run-start and additional charges, plus your workload, determine total cost. Unavailable means the snapshot did not provide the value; an explicit FREE model is separate from a zero listed event rate. You are responsible for complying with detector.io's terms and applicable law. How we measure.
