Using the panel

Right-click a selection

Highlight a name anywhere and choose Look up “…” from the context menu. This path needs no site access at all, so it works even on a fresh Firefox install where you have granted nothing.

The toolbar button

Clicking the extension icon opens the panel. If you selected a name just before, the panel opens already showing it.

Ctrl + Shift + L

⌘ + ⇧ + L on a Mac. Handled natively by the browser and rebindable — chrome://extensions/shortcuts on Chrome, the gear menu at about:addons on Firefox.

The search box

Type any name into the field at the top of the panel; it searches as you pause. A bare label with no dot resolves to .com — typing grok looks up grok.com — while grok.bot is used exactly as typed. Press Enter to force the lookup; only then will a junk string get told it is not a domain.

The current-tab button

The globe button beside the search field looks up the domain of the page you are on.

Recent chips

The last twelve lookups, one click each.

Pasting a URL

Paste a whole URL and the registrable domain is pulled out of it. Select a subdomain and the networked lookups still target the registrable domain — docs.example.com queries example.com, with the subdomain noted under the header.

Status pills

The one-glance summary: Registered or Available, whether DNS is delegated, whether the nameservers belong to a parking broker, whether the name can receive email, and a red pill when the registration is in redemptionPeriod or pendingDelete — or an amber one when it expires within 30 days.

Site preview

Title, description, og:image and theme colour, parsed from the head of the domain root. A red redirects off-domain flag appears when that root lands on a different registrable domain — the usual tell for a sale lander or an abandoned redirect.

Local score

A 0–100 composite of six local signals with the breakdown underneath: which dictionary words the label segments into, how pronounceable the letter sequence is, its character pattern, and its length. Computed on your machine — no network, no opinion from a server.

History

The first Wayback Machine snapshot, linked so you can go look at it. If that snapshot predates the registry’s creation date, the card says the name had a previous life.

Research

Appraisal, sale comps, cross-TLD usage, UDRP dispute history and trademark search, each prefilled with this name. Plain nominative links — no referral codes, no affiliation implied. Eleven tools are available and six are on out of the box; each has its own checkbox in settings.

Registration

The registry record over RDAP: created, expires, updated, registrar and IANA id, EPP status codes, registry nameservers, DNSSEC. Critical statuses sort to the front and turn the row red. For an available name this card is absent — the register button at the bottom says it better.

DNS

NS, A and MX records with the rest folded into a +n, plus an email-auth line for SPF and DMARC. A parked name names its broker here too.

Recent

The last twelve names you looked up, as chips. Click one to go back to it; the ✕ clears the list.

Any of these can be reordered or switched off — see the layout settings.

Click the name

Copies it. The uppercase line and the punycode line under it are separately copyable too, which is handy when a registrar form wants the xn-- form.

⧉ Copy summary

Puts the whole lookup on your clipboard as Markdown — score, registration, DNS, archive date, the lot. Made for pasting into a ticket or a chat.

↗ Open

Opens the domain in a new tab.

↻ Refresh

Drops the cached record for this name and re-runs every source from scratch.

One bar, two forms, and most of the time neither: it appears only when there is something to do with the name.

Register on <your registrar>

Shown once the registry answers that the name is unregistered. It deep-links into the registrar you picked in settings with the name prefilled, and carries no referral code.

Buy now on Atom.com

Shown when the name is registered and its nameservers say it is listed for sale on Atom.com. This link carries an affiliate referral code — the developer may earn a commission if you buy through it, and it is the only monetised link in the extension. It is on by default and switches off under Buy now button in settings; the full disclosure is on the privacy page.

Every lookup is cached locally for 24 hours, keyed by registrable domain, and each source merges into that one record as it lands. Looking the same name up again inside that window issues zero network requests — it renders from storage. Unreachable sites are cached as unreachable too, so a dead domain does not re-time-out at you every time.

Concurrent lookups of the same name share one in-flight request, and requests are gated to two at a time per host, so a fast series of selections cannot stampede a registry. When you want fresh numbers anyway, that is what ↻ is for.
