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.

A permanent Clip Studio Paint forever license with quality pen input devices can be a good option. Blender also offers free rigged 3D base models that offer similar functionality too. Render a png of the 3D pose in 4k, and have fun in free Krita. Ymmv with pen-pressure sensitivity features, as some devices are better than others. =3 https://studio.blender.org/characters/ https://krita.org/en/. - Source: Hacker News / about 2 months ago
> I built WebPtoPNG after getting frustrated with converters that throttle uploads or phone data Why would you want to do it in a browser anyway? Just run it local. There are many open source image editors and converters to choose from. ImageMagick is one: https://imagemagick.org/ GIMP is another: https://www.gimp.org/ Krita is another: https://krita.org/en/. - Source: Hacker News / 7 months ago
We found running a recent Intel pen tablet is nice for some applications like the full blender plugin ecosystem support, commercial and free offerings. Some treasure: https://github.com/wonderunit/storyboarder/releases https://krita.org/en/ Avoid in commercial use-case: https://github.com/Acly/krita-ai-diffusion Seems ridiculous, but the 2nd paid seat you get works well for portable non-intensive tasks:... - Source: Hacker News / 11 months ago
Fairly well known on HN by now but Krita is also excellent and simple image editor and painting app like Photoshop was 20 years ago https://krita.org/en/. - Source: Hacker News / about 2 years ago
