Features and specs

What each product offers, as listed by its team.

NormAPI 5 features
Xml Viewer.app 0 features
  • API-first developer approach
    NormAPI is built for developers, so its services can be integrated into applications through REST-style endpoints instead of manual workflows. This usually means faster integration and easier automation. I could not verify the details of the current product, so check the live site for the exact feature set.
  • Reduces in-house development effort
    Using a hosted API lets teams avoid building and maintaining this functionality themselves. That saves engineering time and ongoing maintenance, especially for small teams and startups.
  • Scalable, usage-based model
    Hosted API services like this typically let you start small and scale with demand, so you don't have to manage infrastructure. Confirm the actual pricing tiers and rate limits on the official pricing page.
  • Language-agnostic integration
    Because it is exposed over HTTP, it can be called from almost any language or platform, such as Python, JavaScript, Ruby, or PHP. This makes it flexible across different tech stacks.
  • Quick start for prototyping
    A hosted API usually requires only an account and an API key, so teams can test and prototype quickly before committing to a larger integration.

Questions & Answers

As answered by people managing NormAPI and Xml Viewer.app.

Why should a person choose your product over its competitors?

Xml Viewer.app's answer:

Choose XML-Viewer.app when you need to quickly read an XML invoice or inspect an XML file without installing software. It provides readable invoice layouts alongside XML viewing and formatting, with document processing kept on your device. It is a focused option for users who need to view documents without adopting a full invoicing or accounting system.

What makes your product unique?

Xml Viewer.app's answer:

XML-Viewer.app combines a general-purpose XML viewer with electronic invoice rendering. Supported XML invoices are displayed as readable documents with supplier and customer details, line items, taxes and totals. Users can switch to the XML source to inspect the underlying data. All parsing and rendering happens locally in the browser, without uploading document contents to a server.

How would you describe the primary audience of your product?

Xml Viewer.app's answer:

People who receive electronic invoices as XML files and need to read their contents, including small business owners, accountants and finance teams. It also serves developers and integration specialists who need to inspect and format XML or compare an invoice's readable view with its source data.

What's the story behind your product?

Xml Viewer.app's answer:

XML-Viewer.app was built around a simple goal: make XML useful to the person opening it. For developers, that means clear formatting and convenient inspection. For someone receiving an electronic invoice, it means seeing a readable invoice rather than a page of XML tags. The project brings both workflows together in a browser-based application that processes documents locally.

Which are the primary technologies used for building your product?

Xml Viewer.app's answer:

Next.js and React for the web application, with client-side XML parsing and document rendering. XML files are processed in the user's browser.

Who are some of the biggest customers of your product?

Xml Viewer.app's answer:

XML-Viewer.app has recently launched and does not yet have publicly announced customer references.
