Is domain analysis read-only and safe to run?

Best move: run it against any domain you have a reason to look at. sniff_domain only reads, so there is no write path, no login, and no way for a call to damage the target or your own state.

Why it works: the tool issues GET requests against public pages, plus standard DNS and certificate lookups. It never authenticates, writes, or stores, so the worst case is a few ordinary log lines on the target’s server.

Key takeaways

• sniff_domain is read-only: GET requests to public URLs plus public DNS and TLS certificate reads, with no writes, no auth, and no form submits.
• The service is stateless: no call depends on the one before it. Your results are stored against your account, and the privacy policy covers them.
• Keyless means there is no credential to leak. The free tier is rate-limited; the paid tier uses OAuth scoped to volume.
• A crawl is passive but not invisible. Your requests appear in the target’s server logs like any visitor, and Bassethound does not pretend otherwise.
• It reads only what a browser could reach. It does not attempt gated pages, port scans, path fuzzing, or exploits.

What does “read-only” mean here?

Read-only describes what the tool does to the target, not what it returns to you. sniff_domain issues HTTP GET requests against public pages, then reads public DNS records and the TLS certificate the site presents on the wire. GET is a safe method by definition: it asks for a representation and changes nothing on the server (RFC 9110). The tool never sends POST, PUT, or DELETE, never logs in, never submits a form, and never posts a query that a backend would persist. It does not brute-force paths, guess credentials, or probe for vulnerabilities. So the whole interaction has the same shape as a careful visitor loading your homepage and a few well-known files (llms.txt, .well-known entries), plus the public lookups any DNS resolver performs. There is no write path in the tool, which means there is no state on your side for it to corrupt. The dossier you get back is a read of public signals, correlated across five layers, and returned once.

Does analyzing a domain leave a trace?

Yes, and pretending otherwise would be dishonest. Every GET the crawler sends lands in the target’s access logs: an IP, a timestamp, a user agent, a path. On the free tier those requests come from Bassethound’s crawler and are rate-limited. This is passive reconnaissance, not a stealth operation. The crawler reads public surfaces and makes no attempt to hide. If your threat model requires that the target never sees a request, this is the wrong tool, because no honest domain analyzer can promise invisibility while still fetching pages. sniff_domain never generates the noisy pattern of an active scan: no port sweeps, no path fuzzing, no repeated probing that trips a WAF. A standard call looks like a browser session plus routine DNS and certificate checks. The deep profile adds a few follow-on fetches and a Wayback history lookup, still all reads. The footprint stays small, and it looks like exactly what it is.

Is it safe to run against domains you do not own?

Safe and routine. sniff_domain touches only public surfaces: pages served to anyone, DNS published to the world, and the certificate a site presents on every TLS handshake. It does not attempt gated pages, authenticated APIs, or anything behind a login. This is the same class of work that OSINT and infrastructure tools do (WHOIS lookups, certificate transparency reads, header inspection), and it is why sales, security, and research teams analyze domains they have no relationship with every day. The distinction that matters is active versus passive. Internet-wide scanners like Shodan and Censys knock on services to see what answers. Bassethound reads what the domain already publishes. You are not accessing anything the owner did not choose to serve. Jurisdiction and intent still matter, so use judgment about volume and purpose. The tool itself stays on the read-only, public side of the line, which is what makes analyzing a prospect’s domain or a competitor’s stack unremarkable.

What does stateless add to safety?

Statelessness is a claim about the request boundary. Every call to sniff_domain is self-contained: it takes a domain and a profile, does the work, and returns the dossier, with no call depending on the one before it. What it does not mean is that nothing is written down. Your results are stored against your account, and the privacy policy is the authoritative statement on what is kept and for how long. The safety question that statelessness does answer is the caller’s: calls are idempotent and safe to retry, because a failed request left no half-written state to reconcile. You get the same read of the same public signals whether it is the first call today or the thousandth.

Could a single call harm the target site?

No, by design. A standard call fetches the homepage and a handful of well-known files, then does public DNS and certificate lookups. That is a lighter load than a single real user browsing the site, which pulls dozens of assets. The free tier is rate-limited, so you cannot turn the tool into a flood, and the crawler bounds its concurrency. There is no path fuzzing, no retries hammering an endpoint, no attempt to exhaust a form or an API. The deep profile adds follow-on probes and a Wayback lookup, and those extra fetches stay bounded and read-only too. Contrast this with load testing or scanning, which are built to push a system. Domain analysis is built to observe one, not push it. The honest caveat is capacity: a site already at the edge of falling over can be tipped by any request, including a legitimate visitor. Bassethound does not add meaningful load beyond that ordinary baseline.

Bassethound perspective

Most enrichment tools treat your queries as inventory: the corpus they build from your usage is the product, resold back to the next buyer. We do not do that. Your results are stored against your account so the service can answer for what it did, and the privacy policy governs them, but they are not a corpus we sell and not a profile of you. Our value is fusion in one call, five correlated layers on demand, not a warehouse of everything we have crawled. The keyless design is the same argument from a different angle. Bring-your-own-key tools ask you to paste provider credentials into a third party, a standing risk you carry for the life of the key. Because we own the crawl, the free tier needs no key at all, and the paid tier uses OAuth scoped to volume, not a secret you hand over. Read-only, stateless, keyless: three choices that each remove a way for the tool to hurt you. A competitor selling a corpus and asking for your keys is selling you risk you do not need.
