Four things Joe asked for, one of which needed a decision he did not
make.
WHITE BUTTON LABELS. "White on both themes" could not be done by reusing
--brand: white on the dark theme's #9896E0 is 2.70:1, which fails AA
outright and would have looked washed out rather than crisp. Buttons now
have their own background — #5A58C8 light, #5A58D6 dark, the same
periwinkle the desktop app already uses for its primary button — at
5.52:1 and 5.73:1. The label is white in both, which is what makes the
control read as the same object when the theme changes. Contrast was
computed before choosing the colour rather than after somebody
complained.
PRICING. Cards are equal-height flex columns so the buttons line up
regardless of how many features each lists. The featured tier is marked
by a rule along its top edge and a badge rather than a different fill —
it is the same object, just the one being pointed at. Differentiating
features are bold, each tier carries a one-line footnote answering the
question the price raises ("Annual only", "Over 20 seats? We will quote
you"), and the feature text now says what the thing does rather than
naming it: "a malicious binary is refused before it runs, in 2 ms".
COPY BUTTONS are a clipboard icon that becomes a green tick, with
aria-label toggling to "Copied" so it is not a visual-only signal.
GEO AND SEO — the part with real leverage:
- JSON-LD SoftwareApplication with 11 features and all three offers,
and a FAQPage with nine questions.
- A VISIBLE FAQ backing that schema. Schema describing content that is
not on the page is both invalid and dishonest, so the nine questions
are really there, in <details> elements, and they are the questions
somebody actually asks before installing a root daemon.
- llms.txt — a structured summary written for a model deciding whether
to recommend Hound, including a section of honest limitations.
Linux only, no RPM package yet, gate needs root, small rule pack,
full-download definitions. A recommendation that omits those is
worse than none, and a model that repeats them is a model that got
the answer right.
- robots.txt naming GPTBot, ClaudeBot, PerplexityBot, Google-Extended,
Applebot-Extended, CCBot and others explicitly. Hound exists partly
to be used BY coding agents; an agent reading this site should not
have to guess whether it is welcome. Several of those crawlers treat
silence as refusal, and silence is not the same as consent.
- Canonical, Open Graph, Twitter card, theme-color, sitemap.
Every number in the structured data and in llms.txt is measured or comes
from a published feed. No ratings, no awards, no "trusted by" — a model
that quotes a fabricated number does more damage than one that quotes
nothing, because it is confident.
All four assets verified live: HTML 200, robots 200, sitemap 200,
llms.txt 200, and both JSON-LD blocks parse from the served page.

<script type="application/ld+json">{"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "Is Hound an antivirus?", "acceptedAnswer": {"@type": "Answer", "text": "Partly, and the interesting part is not. Hound does scan files and quarantine malware, but traditional antivirus databases are overwhelmingly Windows malware, which is close to irrelevant on a Linux developer machine. What actually compromises those machines is a dependency, a model file or a repository, so most of Hound is supply-chain and agent-era detection rather than file signatures."}}, {"@type": "Question", "name": "How is Hound different from ClamAV?", "acceptedAnswer": {"@type": "Answer", "text": "ClamAV's corpus is mostly Windows malware, useful if you are a file server passing infections along to Windows clients. Hound is Linux-native: it refuses a malicious binary at execve rather than reporting it afterwards, and its 235,577 indicators are packages that exist only to be malware, drawn from the OSSF malicious-packages feed. Hound can use clamd alongside it for the Windows-carrier case, but does not require it."}}, {"@type": "Question", "name": "Does Hound slow my machine down?", "acceptedAnswer": {"@type": "Answer", "text": "The execution gate adds about 0.8 milliseconds to a program starting, and sustains over 4,000 executions per second. On a server running 21 containers, 16 Node processes and a web server, arming it did not move request latency or load average. A verdict cache means a program you have already run is answered from memory without re-reading it."}}, {"@type": "Question", "name": "What happens if Hound crashes while it is blocking programs?", "acceptedAnswer": {"@type": "Answer", "text": "Nothing. The gate fails open: a watchdog releases any execution that has not been answered within 500 milliseconds, and if the daemon dies outright the kernel releases everything pending when its descriptor closes. A bug in an antivirus must never be able to freeze a machine, so that path is tested rather than assumed."}}, {"@type": "Question", "name": "Is Hound open source?", "acceptedAnswer": {"@type": "Answer", "text": "The agent is Apache-2.0 and the source is public. You are being asked to run a root daemon that can block execution, so you should be able to read it. Definitions are signed with a key whose public half is compiled into the binary, so anyone can verify that the definitions they received are the ones that were published. What is paid for is the threat feed, the console and support."}}, {"@type": "Question", "name": "Can my coding assistant use Hound?", "acceptedAnswer": {"@type": "Answer", "text": "Yes. Hound ships an MCP server with four read-only tools, so Claude, Cursor, VS Code or anything else that speaks MCP can check a project before installing its dependencies, check a single package or model file, and audit the MCP servers it is already trusting. There is deliberately no tool that can delete or quarantine anything: an assistant that can be persuaded by the repository it is reading must not be able to make your antivirus destroy files."}}, {"@type": "Question", "name": "What does Hound detect that other scanners do not?", "acceptedAnswer": {"@type": "Answer", "text": "Packages whose install script pipes a remote script into a shell before you have used any of their code. Package names an AI invented that somebody then registered. Model files whose pickle stream calls os.system when loaded. Instructions in CLAUDE.md or .cursorrules aimed at your assistant rather than at you. MCP servers downloaded fresh from the internet on every launch and handed an API token. Setuid binaries no installed package claims."}}, {"@type": "Question", "name": "Does Hound phone home?", "acceptedAnswer": {"@type": "Answer", "text": "No telemetry by default, and it can run fully offline with definitions imported from a file, which is how it works in air-gapped and regulated environments. The only network request it makes is fetching signed definition packs, and you can point that at your own mirror."}}, {"@type": "Question", "name": "Which Linux distributions does Hound support?", "acceptedAnswer": {"@type": "Answer", "text": "Ubuntu, Debian and Linux Mint have packages today. An AppImage runs anywhere without installing, though it cannot provide the execution gate, which needs privileges an uninstalled bundle does not have. RPM and Arch packaging exists but is not yet built and published."}}]}</script>

<h2>What people ask before installing it.</h2>
|
|
<div class="faq">
|
|
<details>
|
|
<summary>Is Hound an antivirus?</summary>
|
|
<p>Partly, and the interesting part is not. Hound does scan files and quarantine malware, but traditional antivirus databases are overwhelmingly Windows malware, which is close to irrelevant on a Linux developer machine. What actually compromises those machines is a dependency, a model file or a repository, so most of Hound is supply-chain and agent-era detection rather than file signatures.</p>
|
|
</details>
|
|
<details>
|
|
<summary>How is Hound different from ClamAV?</summary>
|
|
<p>ClamAV's corpus is mostly Windows malware, useful if you are a file server passing infections along to Windows clients. Hound is Linux-native: it refuses a malicious binary at execve rather than reporting it afterwards, and its 235,577 indicators are packages that exist only to be malware, drawn from the OSSF malicious-packages feed. Hound can use clamd alongside it for the Windows-carrier case, but does not require it.</p>
|
|
</details>
|
|
<details>
|
|
<summary>Does Hound slow my machine down?</summary>
|
|
<p>The execution gate adds about 0.8 milliseconds to a program starting, and sustains over 4,000 executions per second. On a server running 21 containers, 16 Node processes and a web server, arming it did not move request latency or load average. A verdict cache means a program you have already run is answered from memory without re-reading it.</p>
|
|
</details>
|
|
<details>
|
|
<summary>What happens if Hound crashes while it is blocking programs?</summary>
|
|
<p>Nothing. The gate fails open: a watchdog releases any execution that has not been answered within 500 milliseconds, and if the daemon dies outright the kernel releases everything pending when its descriptor closes. A bug in an antivirus must never be able to freeze a machine, so that path is tested rather than assumed.</p>
|
|
</details>
|
|
<details>
|
|
<summary>Is Hound open source?</summary>
|
|
<p>The agent is Apache-2.0 and the source is public. You are being asked to run a root daemon that can block execution, so you should be able to read it. Definitions are signed with a key whose public half is compiled into the binary, so anyone can verify that the definitions they received are the ones that were published. What is paid for is the threat feed, the console and support.</p>
|
|
</details>
|
|
<details>
|
|
<summary>Can my coding assistant use Hound?</summary>
|
|
<p>Yes. Hound ships an MCP server with four read-only tools, so Claude, Cursor, VS Code or anything else that speaks MCP can check a project before installing its dependencies, check a single package or model file, and audit the MCP servers it is already trusting. There is deliberately no tool that can delete or quarantine anything: an assistant that can be persuaded by the repository it is reading must not be able to make your antivirus destroy files.</p>
|
|
</details>
|
|
<details>
|
|
<summary>What does Hound detect that other scanners do not?</summary>
|
|
<p>Packages whose install script pipes a remote script into a shell before you have used any of their code. Package names an AI invented that somebody then registered. Model files whose pickle stream calls os.system when loaded. Instructions in CLAUDE.md or .cursorrules aimed at your assistant rather than at you. MCP servers downloaded fresh from the internet on every launch and handed an API token. Setuid binaries no installed package claims.</p>
|
|
</details>
|
|
<details>
|
|
<summary>Does Hound phone home?</summary>
|
|
<p>No telemetry by default, and it can run fully offline with definitions imported from a file, which is how it works in air-gapped and regulated environments. The only network request it makes is fetching signed definition packs, and you can point that at your own mirror.</p>
|
|
</details>
|
|
<details>
|
|
<summary>Which Linux distributions does Hound support?</summary>
|
|
<p>Ubuntu, Debian and Linux Mint have packages today. An AppImage runs anywhere without installing, though it cannot provide the execution gate, which needs privileges an uninstalled bundle does not have. RPM and Arch packaging exists but is not yet built and published.</p>
