issued.live / How issued.live compares # How issued.live compares Four services people weigh against this one, with what each covers and what it costs. Every figure below comes from the vendor's own site. Prices and dataset sizes observed 14 September 2026 and sourced from each vendor's own pages. Pricing changes; check the vendor before buying. Where a vendor does not publish a price, this page says so rather than estimating one. ## At a glance | | issued.live | AllZonefiles.io | Domains-Monitor | WhoisXML API | crt.sh | |---|---|---|---|---|---| | Cost | | Entry price | **$39/mo** | $39/mo | $9/mo | not published for bulk data | free | | Higher tier | $39–$199/mo | $79/mo | $29/mo | quote only | n/a | | Free tier without an account | Yes | No | No | NRD sample only | Yes | | Coverage | | Domains counted | **425,080,869** | 383,238,375 | 346,208,954 | not stated as one figure | no domain index | | Certificate Transparency | Yes | No | No | Yes | Yes | | Certificate internals: SPKI, JA4X, SANs | Yes | No | No | Yes | Yes | | DNS records | Yes | No | Yes | Yes | No | | DNS per vantage point | Yes | No | No | No | No | | Registration dates and registrar | Yes | selected zones | Yes | Yes | No | | Zone-file population | Yes | Yes | Yes | Yes | No | | Registrant contact details | No | No | Yes | Yes | No | | History | | Certificate history kept | 14 days live, files kept forever | n/a | n/a | 15+ years | since 2013 | | Dated historical snapshots | No | ~15 months | since Apr 2022 | Yes | Yes | | Access | | Bulk files available today | Yes | Yes | Yes | Yes | No | | Dated event timeline for one domain | Yes | No | No | No | No | | Query a single domain by API | Yes | No | No | Yes | Yes | | Search by IP, certificate, SPKI or JA4X | Yes, by API | No | No | Yes | SQL only | | Company-size limit on the license | None | under 5 staff | None | negotiated | None | ## Where each one wins ### AllZonefiles.io [allzonefiles.io](https://allzonefiles.io/) · bulk domain-name lists by TLD Basic $39/mo · Pro $79/mo · Enterprise quote only 383,238,375 domains across 1,582 zones, updated daily by 09:00 UTC. The product is domain names: gzip text, one name per line, plus daily added and removed lists. #### Better than us - About 15 months of dated historical snapshots on the $79 tier, with 448 dated `.com` files going back to June 2025. - The whole namespace in one 1.5 GB archive, refreshed daily and fetched in one call. #### Not in their product - Certificates of any kind, and no DNS resolution records. - Any way to look up one domain. The API lists zones and downloads files. - Basic and Pro are licensed to organizations with fewer than five full-time staff, and internal use only. Five staff or more means an Enterprise quote. ### Domains-Monitor [domains-monitor.com](https://domains-monitor.com/) · bulk domain lists with contact and hosting data Standard $9/mo or $89/yr · Pro $29/mo or $299/yr 346,208,954 domains in 1,570 zones, refreshed daily around 00:00 CET. The cheapest way in of anything here, and they sell annual billing that we do not. #### Better than us - A lower entry price at $9. - Point-in-time global snapshots twice a year back to April 2022. - Registrant contact data as a product, which we do not collect. #### Not in their product - Certificates and Certificate Transparency, entirely. - Whois and RDAP records as such. They sell derived contact fields instead. - DNS from more than one vantage point. If you are considering their contact-data products, read their license and take your own view on redistributing personal data in your jurisdiction. ### WhoisXML API [whoisxmlapi.com](https://www.whoisxmlapi.com/) · whois, DNS, certificate and IP intelligence Metered APIs priced publicly · bulk databases and feeds quote only The most complete of the four, and the oldest. Around 30 query APIs plus a catalog of bulk downloads. Newly registered domains land daily at 05:00 UTC. #### Better than us - Depth we cannot match: 28.7 billion historical whois records over 1.2 billion domains from 15 years of crawling, and 116 billion DNS records. - Per-call metered pricing, so a low-volume question costs a few dollars rather than a monthly subscription. - Parsed registrant fields normalized across TLDs. #### Worth knowing - No published price for the bulk data. Every NRD package and database download is a quote. - Their free allotments need an account, and the whois grant is 500 calls once rather than a recurring allowance. - Historical NRD files are kept 7 days on the lower tiers, 30 days on Enterprise and 365 on Ultimate. ### crt.sh [crt.sh](https://crt.sh/) · free Certificate Transparency search, run by Sectigo Free. No account, no key, no paid tier. The baseline everyone should try first. If your question is only about certificates, this may be all you need, and it costs nothing. #### Better than us - Every CT-logged certificate since 2013, searchable interactively. Our queryable window is 14 days. We keep our daily certificate files indefinitely, but answering "what did this domain have in 2019" is their product, not ours. - A public read-only PostgreSQL endpoint, so you can run arbitrary SQL over the whole dataset. - Certificate linting, and root-program monitoring across Mozilla, Apple and Chrome that we do not attempt. #### Not in their product - DNS data of any kind. - Whois, RDAP, registrar or registration dates. - Zone files, so no notion of a TLD's full population, and no domain-level index. A domain appears only once a CA issues a certificate for it. ## Choosing **You want certificate history going back years.** Use crt.sh, and it is free. Our queryable window is 14 days. We do keep every daily certificate file indefinitely, so an older date is a file we can send you, but crt.sh answers that question interactively and we do not pretend otherwise. **You want the cheapest bulk domain list.** Domains-Monitor at $9, or AllZonefiles at $39 if you want the daily added and removed lists as separate products. **You want registrant contact details or 15 years of whois history.** WhoisXML API. We hold neither. **You want domains, certificates and DNS answering the same question.** That is what this service is for. The other four each cover one or two of those three, and joining their outputs yourself means reconciling three vendors' identifiers. Our [plans](/pricing) are $39, $99 and $199. Something here out of date or wrong? [Tell us](/contact) and we will correct it. We would rather be accurate than flattering. --- issued.live, operated by Tuxxin LLC.
