rdap.org scrapers compared
118 tools that scrape rdap.org, 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: 146. Users may overlap across tools; this is not a count of unique people or buyers, or search volume.
At a glance: 118 tools; 17 of 60 displayed tools have recorded 30-day run completion (20+ public runs); the current usage pick accounts for 20% 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: Bulk Domain Availability Checker + WHOIS (RDAP) Lookup (29 users in 30 days).
Most reliable with 300+ runs: Bulk Domain Availability Checker + WHOIS (RDAP) Lookup (93.7% of 457 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: 59 with a recorded primary-event rate; 0 with an unavailable primary-event rate; 1 with an explicit FREE model. Primary-event rates use the recorded billing units below; different events are not equivalent results.
Comparison evidence
Compare two tools
Add tools from the rows below, or choose either side here. When both sides are filled, adding a row replaces the right tool.
Recorded primary-event amounts only; run starts, other events and platform charges can add cost. Matching event IDs do not establish equivalent output or total cost. Some links are affiliate links; we may earn a commission. Disclosure.
No tools match these filters. Change the filters or use Reset filters to show all tools.
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.
Default order: 30-day usage.

Download the rdap.org 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 rdap.org's terms and applicable law. How we measure.

Estimate recorded billing-event charges
Dataset file date: 2026-10-21; this does not date each tool’s recorded price. See tool observations in the table. Quantities refer to the selected tool’s billing event, not a result count. Changing tools clears both quantities; enter a workload for the new unit.
Partial estimate only: excludes other charge events, platform compute, subscriptions, taxes and unknown charges. No output requirements are inferred. Run-start charges are included only when a numeric rate is recorded and a run count is supplied.

Select two to four tools using the checkboxes in the table. Evidence stays in the original table order.
Primary-event rates exclude run-start and other charges. Different billing events do not imply equivalent results or total costs. Observed public-run reliability over 30 days is not a guarantee for your workload. Unavailable means the snapshot did not provide the value.
