NameSilo

NameSilo — Flat renewals, free privacy and portfolio tooling for people holding hundreds. NameSilo prices close to cost, includes WHOIS privacy free, and — unusually — charges about the same at renewal as at registration. Its bulk tooling is built for portfolio holders rather than for someone buying their first domain. The interface looks like it was designed in 2012 and has not meaningfully changed, which is either a problem or a feature depending on how many domains you own. Built by NameSilo LLC. Founded 2009.

We track it in 2 comparisons — Domain registrars and Domain APIs — so every claim below is a cell in a table you can open and check rather than an impression. Across those rosters it sits against 21 other tools, and what follows is where it visibly separates from them.

Where it wins.

• Domain registrars — .com renewal — $12.99 /yr, 4th of 15.
• Domain APIs — Privacy via API — free-and-default, tied for best across 5 of 15 tools.

Each of those is ranked against the whole roster on its category page, not against a hand-picked subset, so a first place here means first of everything we list.

Where it gives ground.

• Domain APIs — .au support — No. OpenSRS records Yes.

None of these disqualify it on their own. They are the fields to check against your own requirements before you commit, because they are the ones where a competitor genuinely does better.

Provenance. 46 of 51 tracked fields carry a value for NameSilo, and 8 of those cite a document you can open. Last verified 2026-07-23. Every figure keeps its own provenance — measured by us, claimed by the vendor, inferred, or community-reported — and we would rather print a dash than a guess.

Its nearest neighbour in our data is Dynadot. NameSilo is ahead on Sandbox / OTE (Yes against No) and At-cost pricing (Partial against No). Dynadot takes EPP code via API (Yes against Partial) and Support quality (4 against 3). That pattern repeats across the rest of the roster — see NameSilo alternatives for the other rivals, each compared the same way.

The registrar for people who own more domains than they can name. Flat renewal pricing and serious bulk operations, wrapped in a dashboard that has aged without dignity.

NameSilo is the right call in these situations, each one drawn from a field we actually record:

• Domain registrars — Portfolios in the hundreds where bulk edits are a weekly task.
• Domain registrars — You want the renewal to equal the registration price, permanently.
• Domain registrars — Cost discipline matters more than UI.
• Domain APIs — Registering on behalf of customers without a reseller contract.
• Domain APIs — Cost-sensitive bulk portfolios.
• Domain APIs — Teams that want free WHOIS privacy applied automatically.
• .com renewal is your binding constraint. NameSilo records $12.99 /yr, 4th of 15 in the Domain registrars roster. We define that field as advertised price of a one-year .com renewal at standard rates, excluding tax and excluding loyalty or club discounts that cost money to join.
• Privacy via API is your binding constraint. NameSilo records free-and-default, the best figure in the Domain APIs roster. We define that field as whether WHOIS/RDAP privacy can be controlled from the API and what it costs at your tier.

Reach for something else when any of the following is a requirement rather than a nice-to-have:

• .au support. NameSilo records No on the Domain APIs table. OpenSRS records Yes on the same field. If that is a hard requirement rather than a preference, start elsewhere.

We publish this block because a comparison that only lists what a tool is good at is marketing. Every figure above sits on the same page as its source, and the field definitions are on the category tables if you want to check how we measured them.

What we don't know. 5 of the 51 fields we track for NameSilo are still blank: .com.au renewal, .au accredited, Domains managed, Ownership and Rate limit. Those render as dashes rather than as zeroes or assumptions, because an empty cell and a bad cell are not the same thing and only one of them is honest. If you know any of these figures and can point at a document, tell us.
