guest@abr:~$ abr --modes

One app, four modes.

Everything below is the real web app at nettools.abr.cloud — no mockups.

guest@abr:~$ abr monitor example.com --watch

We watch it,
so you don't have to.

Point abr.cloud at a domain or server and it checks — around the clock, from the cloud, no agent required — whether your site is up, your TLS certificate is about to expire, and your email posture (SPF/DMARC/MX) still holds. The moment something breaks, you get a plain-language email that says what and how to fix it. Every plan includes a monitor — even Free.

[watch]

Always-on, from free

Uptime, TLS-expiry, ports and a 7-check Domain Health composite, checked on a schedule. Alerts are spike-proof — we re-check before we email, so no false-alarm floods.

[fleet]

One calm dashboard

Fleet Health folds every open issue across your domains and servers into one worst-first list in plain language — plus history, uptime %, and server CPU/RAM/disk via a lightweight agent.

[share]

Share it — or white-label it

Turn any monitors into a public status page. Agencies & MSPs get it fully white-label — your brand, your domain, client-ready PDF reports — from €29/mo.

guest@abr:~$ abr investigate example.com --grade

Point it at a domain.
Get a graded report.

Investigate is the AI agent inside abr.cloud. Give it a target you're authorised to assess — a domain, website or IP — and it picks the right checks, runs them, and chains each result into the next. You get one plain-English report with an overall grade and prioritised fixes.

[assets]

Asset & infra audits

Domain & website, IP & infrastructure, email spoofability, company due-diligence — every finding grounded in real tool output, never guessed.

[chain]

Chained automatically

It works the loop — scope, collect, pivot, verify, document — so DNS, mail records, certificates and headers all get followed without you lifting a finger.

[report]

A report you can act on

Overall grade, findings with severity, plain meaning and the fix — saved to your history and exportable as a branded PDF.

guest@abr:~$ whoami --studio

Small by choice.

We'd rather ship one sharp tool than ten dull ones.

Substance first, then craft: every result explains itself in plain language, and the whole category deserves better than banner ads and cramped tables — so we're rebuilding it with the polish it never had.

No ads. No dark patterns. No selling your data. Ever.

Majid Nassir, founder of ABR

Hi, I'm Majid Nassir — the engineer behind ABR. Thirteen-plus years in networking and security across Europe (CCNP, CCNA, CEH), and now a studio of one: I design, build and run everything here myself — every tool, every pixel, every server.

abr is ابر — Persian for cloud. abr.cloud is the one product, built deep instead of wide.
