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.
Chat by Stream CodeClassifyCodeClassify'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.
Based on our record, Chat by Stream seems to be more popular. It has been mentiond 40 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
The stream must deliver high-quality video and audio while also keeping features like real-time chat and updated product information responsive. This becomes more challenging during flash sales, where traffic and purchases suddenly spike. - Source: dev.to / 6 months ago
Because moderation is an add-on to Stream's existing suite (Chat, Video and Audio, and Activity Feeds), it doesn't need to cover its costs through premium enterprise contracts. That makes Stream far more cost-effective than standalone moderation vendors, especially for startups or growing communities that want enterprise-grade safety tools without a sales cycle. - Source: dev.to / 6 months ago
We'll build an MCP server that exposes five tools for working with Stream Chat: creating channels, sending messages, querying channels, creating users, and querying messages. The complete code is about 200 lines, and you can see precisely how MCP works in practice. - Source: dev.to / 7 months ago
In this post, we share the 14 top features for engaging in-app chat, helping you decide what to integrate and how they will add value to your product. - Source: dev.to / 8 months ago
In this guide, we'll learn how to implement E2EE in a React Native chat app using Stream's chat infrastructure. We'll combine public-key cryptography with efficient symmetric encryption to achieve strong security. - Source: dev.to / 9 months ago
