Web & Software Development: Core Web Terms, Codes & Classifications
A free glossary of web and software terms — HTTP status codes, REST and GraphQL APIs, front-end and back-end, SSR and SPA, CI/CD, semantic versioning, WCAG accessibility, Core Web Vitals, plus the SOC and NAICS codes used to classify developer work — with precise plain-language definitions. Platform-curated public-domain reference data, free for engineers, analysts, and technical recruiters.

No answered questions yet — ask the seller anything about this listing.
Data is contributed by independent third-party sellers. Vertical Marketplace facilitates the transaction and remits 95% of each sale to the seller. Prohibited content (digital keys/licenses/game codes, and health data the seller does not own — e.g. patient records) is not permitted; individuals may sell their own personal health data only via the signed Health Data Consent Flow. See /terms.
- Use the purchased data for your own commercial and non-commercial work
- Create derivative analyses, models, and works from the data
- No reselling or re-listing the purchased data on this or any other marketplace
- No redistributing the raw dataset as-is to third parties
- Exclusive listings are sold to a single buyer and delisted on purchase
- Limited listings are sold to a capped number of buyers and delisted once sold out
