Features and specs

What each product offers, as listed by its team.

Taxid.dev 5 features
cppq 5 features
  • Simple API for tax ID validation
    Taxid.dev provides a straightforward API and library for validating and formatting tax identification numbers (like VAT, EIN, etc.) across multiple countries, making it easy for developers to integrate into their applications.
  • Multi-country support
    The tool supports tax ID formats from a wide variety of countries, which is useful for businesses operating internationally and needing to validate different tax ID structures.
  • Open-source availability
    Being open-source (or offering open-source components), it allows developers to inspect the code, contribute improvements, and self-host if needed, increasing trust and flexibility.
  • Free to use
    Taxid.dev offers its core functionality for free, making it accessible for small businesses, startups, and individual developers who need tax ID validation without incurring additional costs.
  • Developer-friendly documentation
    The service typically provides clear documentation and examples, helping developers quickly understand how to implement tax ID validation in their projects.
  • Lightweight C++ implementation
    cppq is written in modern C++ and designed to be a minimal, efficient task queue library, making it a good fit for performance-sensitive applications where the overhead of scripting language runtimes is undesirable.
  • Redis-backed reliability
    Built on top of Redis as the message broker, cppq benefits from Redis's persistence, atomic operations, and wide adoption, giving the queue system durability and the ability to survive process restarts.
  • Inspired by proven design (asynq)
    The library's architecture mirrors the popular Go asynq task queue, so it inherits a well-thought-out API design for task enqueueing, retries, and worker processing patterns that have already been validated in production systems.
  • Native integration for C++ projects
    For teams already working in a C++ codebase, cppq allows adding background job processing without needing to introduce a separate service written in another language (like Go or Python), simplifying the technology stack.
  • Open source and inspectable
    Being open source on GitHub, developers can review the source code, modify it for custom needs, and contribute improvements, which offers transparency not available with closed-source queueing solutions.

Possible disadvantages

  • Limited maturity and battle-testing
    Compared to established task queue libraries like Sidekiq, Celery, or asynq itself, cppq is a newer and smaller project with less real-world production usage, which may translate into undiscovered bugs or edge cases.
  • Smaller community and ecosystem
    Because it has far fewer users and contributors than mainstream task queue systems, finding community support, third-party tutorials, or pre-built integrations is more difficult.
  • Documentation gaps
    As a smaller project, cppq may have less comprehensive documentation compared to major task queue frameworks, requiring developers to read source code directly to understand advanced features or edge-case behaviors.
  • C++ build and dependency complexity
    Using cppq requires managing C++ build toolchains and dependencies (such as a Redis client library), which can be more cumbersome than installing a package via pip or npm in other ecosystems.
  • Fewer built-in features and tooling
    cppq likely lacks the extensive ecosystem tooling of more mature queues, such as web-based monitoring dashboards, extensive metrics/observability integrations, or advanced scheduling features found in more established solutions.

Questions & Answers

As answered by people managing Taxid.dev and cppq.

What's the story behind your product?

Taxid.dev's answer

TaxID was built after running into the same problem on three consecutive client projects: validating EU VAT numbers reliably.

The official EU source — VIES — is SOAP-based, frequently goes down without warning, has no caching layer, and returns errors like "MS_UNAVAILABLE" with no context. Every time, the workaround was the same: write a thin wrapper, add Redis cache, handle the downtime, parse the SOAP response into something usable.

Instead of writing it a fourth time, I built TaxID as a public API. The free tier exists because that's what I would have wanted on those projects — a way to evaluate the product without a sales cycle.

The product is intentionally small: one well-built endpoint, structured errors, fast cached responses. No tax calculation, no nexus tracking, no enterprise dashboard. Just the VIES wrapper VIES should have been.

What makes your product unique?

Taxid.dev's answer

TaxID is the only VAT validation API that combines four things at once:

  • A truly free forever plan (100 validations/month, no credit card)
  • Sub-10ms cached responses via Redis (24h cache on valid lookups)
  • Coverage across 31 countries from a single endpoint — 27 EU member states via VIES, plus UK (HMRC), Switzerland, Norway and Australia (ABR)
  • Stripe-style structured error codes you can branch logic on (vatinvalid, serviceunavailable, countrynotsupported)

Other providers either charge from the first call, only cover EU VIES, or return SOAP/XML you need to parse. TaxID is the thin REST wrapper that just works.

Why should a person choose your product over its competitors?

Taxid.dev's answer

Three reasons:

  1. Developer-first DX. REST, JSON, OpenAPI spec, Stripe-style error codes, country-specific format validation before hitting VIES (so malformed numbers fail instantly without consuming quota). Most competitors are SOAP wrappers with cryptic errors.

  2. Real free tier. 100 validations per month, no credit card. Vatstack, Vatlayer and Avalara either require a card upfront or have hard limits that block real evaluation. With TaxID you can ship a side project to production on the free plan.

  3. Extended coverage. Most VAT APIs stop at the EU. TaxID adds the UK (HMRC), Switzerland, Norway and Australia (ABR) — useful for any SaaS with global B2B customers.

Honest about limits: TaxID is not an enterprise compliance suite. If you need US sales tax nexus, full ERP integration or KYB beyond VAT, look at Avalara or Sovos. TaxID is for developers who need to validate a VAT number reliably inside a checkout or invoice flow.

How would you describe the primary audience of your product?

Taxid.dev's answer

Developers building B2B SaaS or eCommerce products that need to validate company tax IDs as part of their billing flow.

Typical users: - SaaS founders integrating Stripe with EU VAT compliance (reverse charge mechanism) - Backend developers working on B2B checkouts in Node.js, Python, PHP or Go - Indie hackers shipping products to European customers who can't afford enterprise tax compliance tools - Accounting and ERP integration developers - Compliance and KYB workflow builders

The shared trait: they want a clean REST API with a free tier, not an enterprise sales call.

Which are the primary technologies used for building your product?

Taxid.dev's answer

  • Hono on Cloudflare Workers (edge runtime, low cold start)
  • Redis for 24h cache on valid VAT lookups
  • VIES SOAP service (EU Commission) as upstream for all 27 EU member states
  • HMRC API for UK VAT validation
  • Australian Business Register (ABR) for Australian ABN validation
  • TypeScript end to end, with zod for runtime schema validation
  • OpenAPI 3.1 spec auto-generated from route handlers
