Why these seven, and not the fifteen everyone else lists
Free tools directories on the compliance and SEO side usually run to two dozen entries, and about nineteen of those entries are the same tool rebadged for different search queries or a wrapper around a public API that anyone with a curl command already has. The seven tools listed below are the ones we built because our own paid monitoring products (PixelProof, EntryProof, TariffWatch) run the same underlying checks on a schedule for paying customers, and it seemed dishonest to gate a one-shot version behind a paywall when the check itself is a five-second HTML fetch or a table lookup. Each free tool corresponds to a real failure mode we have watched cost a real Shopify or cross-border operator real money in the last twelve months.
The Meta Pixel Debugger, for example, exists because a theme update on Shopify 2.0 in April 2026 silently disabled the pixel loader on the checkout page for one of our test stores and the operator did not notice for eleven days, during which the ad account cost-per-purchase reporting drifted north by more than 40 percent because the algorithm was optimizing blind. The CPSC Penalty Calculator uses the five-factor formula the Commission cites in its published penalty determinations, so an importer can produce a defensible number before a Section 15(b) report deadline instead of guessing. The HTS Code Lookup ships the current Section 232 additional-duty rates because the alternative is a five-tab crawl through USITC, USTR, and Federal Register PDFs to reconstruct what a broker classification screen already shows in one line. Every tool here answers a question we have been asked by a real operator on a real Zoom, not a question a keyword-research spreadsheet said had 6,600 monthly searches.
All 7 tools, what each one does and when to reach for it
Meta Pixel + tracking - Published 2026-08-13
Meta Pixel Debugger

Section 232 + tariffs - Published 2026-08-13
HTS Code Lookup with Section 232 rates
Search 19,000 US Harmonized Tariff Schedule codes and see the current Section 232 additional-tariff rate on steel, aluminum, copper, and the Aug 27 2026 BIS proposed categories.
Paid counterpart when you need this on a schedule instead of one URL at a time: TariffWatch.

CPSC + product safety - Published 2026-08-13
CPSC Civil Penalty Calculator
Estimate CPSC civil-penalty exposure under the Consumer Product Safety Act (15 U.S.C. 2069) using the 5-factor formula the Commission cites in its published penalty determinations.

JSON-LD Schema Markup Generator
15 schema types (Product, Article, FAQ, HowTo, LocalBusiness, Event, Recipe, JobPosting, Course, Video, Book, Review, Organization, BreadcrumbList, Service). Fills in the fields Google actually validates, drops the ones it ignores.

SEO + technical hygiene - Published 2026-08-14
robots.txt Checker and Validator
Fetch your live robots.txt or paste a candidate one. We test what Googlebot, Bingbot, and GPTBot can and cannot crawl, and flag contradictory rules, unknown directives, and stale sitemap links.
Paid counterpart when you need this on a schedule instead of one URL at a time: PixelProof.

Privacy + consent - Published 2026-08-14
GDPR Privacy Policy and Cookie Policy Generator
Answer 12 questions about what you actually collect (email, IP, cookies, payment tokens, analytics IDs). We build a GDPR + UK GDPR + CCPA-aligned privacy policy and cookie policy as a PDF and inline text.
Paid counterpart when you need this on a schedule instead of one URL at a time: EntryProof.

Privacy + consent - Published 2026-08-14
Cookie Consent Compliance Checker
Enter a URL. We fetch the page as a first-time EU visitor and check whether analytics, marketing, and Meta Pixel scripts fire BEFORE consent (GDPR violation) or only after (compliant).
Paid counterpart when you need this on a schedule instead of one URL at a time: PixelProof.
How to use these tools (the workflow that actually catches things)
The single most common way an operator wastes one of these tools is running it once, saving a screenshot, and never running it again. Compliance drift is a process, not an event: the Meta Pixel that scored 10/10 in June breaks in July because a marketing agency installed a new tag manager container that overwrites the base fbq init; the CPSC readiness score that was green last quarter goes red this quarter because a supplier substituted a coating that now falls under 16 CFR Part 1303; the robots.txt that Googlebot happily crawled through last audit gets a new Disallow: / line pushed by a staging-config leak the day before a launch. The workflow that catches this is calendar-based, not event-based: pick a monthly cadence (the first Monday of each month is the common one), run each of the free tools against your top three URLs, homepage, top product page, and checkout, save the results in a dated folder, and diff against last month.
The tools above run against public HTML and public data sources, so they see what an anonymous first-time visitor sees. Anything behind an authenticated session (Shopify checkout scripts loaded from Additional Scripts, GA4 events fired only for logged-in users, GDPR-gated pixels that fire only after cookie consent) is invisible to a URL-based scanner by design; those require either the Meta Pixel Helper Chrome extension running in a real authenticated browser session, or a monitor that runs from inside your admin. PixelProof, EntryProof, and TariffWatch each do exactly that for their respective failure modes on a schedule for paying customers; each free tool linked above is the one-shot version of the check its paid counterpart runs continuously.
The primary sources these tools rely on
Every tool that quotes a legal or regulatory threshold links to the authoritative source. The CPSC Penalty Calculator cites the actual statute at 15 U.S.C. 2069 (Consumer Product Safety Act, civil penalties), the Commission own Section 15(b) reporting guidance, and Federal Register-published penalty determinations. The HTS Code Lookup pulls from the current US International Trade Commission Harmonized Tariff Schedule and cross-references Federal Register Section 232 proclamations. The Meta Pixel Debugger implements the base-install and standard-event contract Meta publishes in its Pixel reference documentation. The robots.txt Checker validates against RFC 9309 (Robots Exclusion Protocol, 2022). Every result page in every tool lists the specific citation that produced its number; if a tool ever gives you a threshold or a rate we cannot cite to a public source, that is a bug, file it at /security-disclosure.
What these tools do NOT do
None of these tools is a licensed customs broker, an FDA or CPSC registered filer of record, a legal-advice service, or a certification body. They tell you what a well-informed operator would spot in ten minutes of manual review, faster and free. If you need someone to actually file, certify, or defend on your behalf, use the tool output as a handoff document for your customs broker or product-liability attorney, several customers use them exactly that way. And none of the tools stores your input beyond a rolling one-hour cache for rate-limiting; nothing you paste into a tool here trains any model, gets sold, or joins a marketing list. See /dpa for the full data-processing terms even though, because these tools are ungated, none of them are actually processing your customer data at all; the DPA covers our paid products, where that distinction matters.

The rest of the portfolio
If you find yourself running one of the free tools every week, that is the point at which the paid product it feeds into starts saving you time instead of costing you money. All three paid products (PixelProof, EntryProof, TariffWatch) start at $99/month, run the same underlying checks on a schedule instead of on demand, and email you the moment something drifts out of compliance rather than the next time you happen to check. The Founding Trio bundle is all three at $299/year for the first 5 customers, real cap, real fulfillment. See /pricing for the full comparison and /products for what each one actually does end-to-end.
Not a customer yet? Every free tool above works with zero signup. Already a customer? Your paid dashboard runs the equivalent check on a schedule and alerts you the moment it changes.
