CodeClassify is a suite of 16 free, browser-based tools plus a deterministic REST API and downloadable CSV datasets for validating, converting and classifying product and business codes: GTIN/UPC/EAN barcode check digits, ISBN, IBAN (MOD-97), EU VAT, VIN, SSCC pallet codes, ISO 6346 containers, ABA routing numbers, and business classifications (NAICS 2022, SIC 1987, the SICโNAICS crosswalk and HS customs codes).
Every result is computed from official public standards (GS1 Mod-10, ISO 13616, U.S. Census, U.S. HTS) โ the same input always returns the same output, with no AI guessing. The free tools need no sign-up and run entirely in the browser; the API and datasets handle bulk validation and automation.

CodeClassify's answer:
E-commerce sellers & ops validating GTIN/UPC/EAN before listing on Amazon, eBay or Shopify
Developers & data engineers needing a deterministic API for bulk validation and classification
Accountants & analysts working with NAICS/SIC business codes
Logistics, customs & trade teams handling HS codes, SSCC pallets and ISO 6346 containers
Finance/fintech teams checking IBAN, EU VAT and routing numbers
CodeClassify's answer:
CodeClassify is deterministic: every result is computed from official public standards (GS1 Mod-10, ISO 13616, ISO 3779, U.S. Census NAICS/SIC, U.S. HTS), so the same input always returns the same output โ no AI guessing, no invented codes. It's also unusually broad: one place to validate, convert and classify barcodes (GTIN/UPC/EAN), ISBN, IBAN, EU VAT, VIN, SSCC, ISO 6346 containers, ABA routing numbers, and business codes (NAICS/SIC/HS) โ as free browser tools, a REST API, and downloadable datasets.
CodeClassify's answer:
CodeClassify runs on Cloudflare Pages for the static tools and Cloudflare Workers + D1 for the API and dashboard. The validation and classification logic is implemented directly from official public standards and datasets (GS1, ISO, U.S. Census, U.S. HTS). Payments are handled by Stripe, and the API is also distributed on RapidAPI.
CodeClassify's answer:
Most alternatives are single-purpose (just barcodes, or just IBAN) or AI-based classifiers that can hallucinate codes that don't exist. CodeClassify covers every major product and business code in one place, computes results from official standards (auditable and repeatable), and offers three ways to use it: free tools with no sign-up, a deterministic API for bulk and automation, and clean CSV datasets. It's built for feeds, compliance and data pipelines where "the same answer every time" matters.
CodeClassify's answer:
CodeClassify started from a simple frustration: product and business codes are everywhere, but checking them meant a dozen scattered, ad-heavy sites โ and newer "AI" tools would confidently return codes that don't exist. The goal was one clean, fast place that computes every answer from the official standard, keeps the everyday tools free and sign-up-free, and offers an API and datasets for teams that need to work at scale.
In contrast to other "private" search engines (except for Presearch and SearX), it doesn't have trackers, or not nearly as many. This information can be verified by installing uBlock Origin and ClearURLs, which detect 0 and 2 trackers respectively, against for example DuckDuckGo's nearly 10 and 19. Other alternatives are SearX (No trackers AT ALL, still kinda user-friendly) and Presearch (A bit easier to use but a tiny bit worse for privacy, it has 1 more tracking element).

1. Check your site on Brave Search. Go to search.brave.com, search for your site name, your top articles, your product. Compare the results to Google. You might find articles that rank well on Google but are invisible on Brave -- or the reverse. When I first did this, I discovered several of my technical posts were completely absent from Brave's index despite ranking on the first page of Google. Different index,... - Source: dev.to / 3 months ago
That alone breaks the basic rule of TDD. And there are great tools like DuckDuckGo, Brave Search and StackOverflow to help us with our needs. - Source: dev.to / 6 months ago
Brave search is also quite nice: https://search.brave.com/ I find Google to generally have some of the worst search results of modern engines with one exception - Google tends to be good at digging up results from things like forums/message boards that don't end up getting listed on other search engines. I don't entirely understand why this is because other engines also have them indexed and work fine with... - Source: Hacker News / 8 months ago
Try https://www.startpage.com/, https://search.brave.com/, https://kagi.com/ or https://github.com/searxng/searxng. You.com used to have really good search, but it looks like they have veered off into the AI chat space instead. Searxng is a self hostable meta search engine that allows you to basically just use the best search engines and easily switch between them. - Source: Hacker News / 11 months ago
