IsValid is a validation API service for developers who need to quickly verify data formats without building their own validators. It offers 40+ endpoints covering financial identifiers (IBAN, BIC, ISIN, CUSIP), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), regional codes (PESEL, REGON, VAT), and more.
The service works on a freemium model โ 100 free API calls per day, no credit card required. Users manage API keys through a dashboard with usage analytics showing daily call volume and per-endpoint breakdowns.

IsValid.dev's answer:
IsValid offers 70+ validators in a single API โ covering financial identifiers (IBAN, BIC, ISIN, LEI), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), tax numbers (VAT, REGON, PESEL), credit cards, phone numbers, and more. No need to integrate multiple services for different data types.
IsValid.dev's answer:
Most validation APIs focus on one category (email or phone). IsValid covers financial, regional, and technical formats all in one place with a consistent REST API. The free tier with 100 calls/day requires no credit card, and integration takes minutes.

The vendor distributes their software as binaries, container images, Helm charts, or Terraform modules, and the customer's platform engineering team handles the full operational lifecycle. This model is common among organisations with strict air-gap or no-internet requirements, teams that need deep customisation of configuration and network topology, and regulated... - Source: dev.to / 5 months ago
Helm 4 is the most significant release since Tiller was removed. New templating engine, dependency resolution changes, and the question everyone's asking: what breaks? The maintainers themselves walk through the migration path. - Source: dev.to / 5 months ago

To get to a working deployment of the proposed app, though, you would probably need to learn at least a dozen different k8s concepts. Hereโs a short list of what you might need: a Deployment to describe Pods in a ReplicaSet along with a Service, Ingress and Ingress Controller to hook up your domain. Helm to install Cert Manager so you can get SSL working. Youโll likely need to learn about plenty more along the way. - Source: dev.to / 9 months ago
