Currawong Web is a China-side desk that checks Chinese suppliers for overseas buyers. Give us the supplier's registered Chinese name — and the 18-character Unified Social Credit Code as well if you have it, which narrows false matches; we read the official Chinese records from inside China and return them in English, with the source named and the query date attached to every line.

A registry snapshot is free before you pay anything, and two browser-side tools need no account: a factory-or-trader read of a registered business scope, and a Unified Social Credit Code checker for GB 32100-2015. Paid packs of registry checks start at US$26.55; a China-side human record check is a fixed US$149 within three business days; on-site factory verification in mainland China starts at US$169 per man-day.

We refuse near matches. The upstream registry API returns the closest company when it cannot find yours, and we reject any result whose registered name is not exactly the one ordered. We also publish our own measurements as open datasets under DOIs, with methods and limits stated, including one conclusion we withdrew after a control experiment contradicted it.

We do not query, proxy or scrape the official government portals from a buyer's browser. Person names are withheld by default; unlocking them is a separate flat fee.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

Currawong Web features and specs

  • Exact-name matching
    The registry API returns the closest company when it cannot find yours. We reject any result whose registered name is not exactly the one ordered.
  • Free registry snapshot
    Registered scope, status, capital, established date and address, at no cost and before you order anything.
  • Every line sourced and dated
    Each delivered line names the platform it came from and the date it was queried. A registry record is a dated fact, not a permanent one.
  • Free browser-side tools
    A factory-or-trader read of a registered business scope, and a Unified Social Credit Code checker for GB 32100-2015. No account, nothing uploaded.

Analysis of s3-lambda

Overall verdict

  • s3-lambda is a useful Node.js library for performing operations like map, reduce, and filter directly on S3 objects using Lambda, making it good for developers who need efficient, serverless-based batch processing of S3 data without managing infrastructure. It is well suited for smaller to medium projects but may not be actively maintained for enterprise-scale needs.

Why this product is good

  • Simplifies common S3 batch operations (map, filter, reduce) with a clean, functional API
  • Leverages AWS Lambda for scalable, serverless parallel processing of S3 objects
  • Reduces boilerplate code for iterating over and transforming large numbers of S3 objects
  • Open-source and free to use, allowing customization for specific workflows
  • Integrates well with existing AWS infrastructure and Node.js applications

Recommended for

  • Developers building serverless data pipelines on AWS
  • Teams needing to process or transform large sets of S3 objects without provisioning servers
  • Node.js developers looking for a functional programming approach to S3 operations
  • Projects with batch processing needs that fit within Lambda's execution limits
  • Prototyping or small-to-medium scale ETL tasks involving S3 data

Questions & Answers

As answered by people managing s3-lambda and Currawong Web.

How would you describe the primary audience of your product?

Currawong Web's answer:

Overseas buyers and sourcing teams who need to check a Chinese supplier and cannot reliably reach the Chinese official portals themselves — importers placing a first order, procurement teams onboarding a new factory, and small distributors without a China office or Chinese-language staff.

It suits one-supplier, one-decision checks rather than continuous screening at scale. A team already running a subscription database and reading Chinese records in-house does not need us.

What makes your product unique?

Currawong Web's answer:

It is staffed from inside China, and it publishes its own limits.

Every delivered line names the platform it came from and the date it was queried, because a Chinese registry record is a dated fact and stops being current the moment something is filed. Person names are withheld by default and unlocking them is a separate flat fee, so a routine supplier check does not quietly become a file on individuals.

The part most buyers never hear about: the registry API this industry runs on does fuzzy matching. Ask for a company it cannot find and it returns the closest one it has — silently, with a complete-looking record. We reject any result whose registered name is not character-for-character the one ordered, and say so, rather than delivering another company's records under your supplier's name.

Why should a person choose your product over its competitors?

Currawong Web's answer:

Because you can check our work before you pay us anything.

The registry snapshot — scope, status, capital, established date, address — is free. Two tools run entirely in your browser with no account and no upload: a factory-or-trader read of a registered business scope, and a Unified Social Credit Code checker that validates the check character against GB 32100-2015.

Beyond that, our measurements are published as open datasets under DOIs, with methods and limits stated, including one conclusion we withdrew after a paired control experiment showed our first reading was wrong. Anyone can download the data and judge whether we are careful. That is a different offer from a report you can only assess after buying it.

What's the story behind your product?

Currawong Web's answer:

It began with a measurement rather than a plan. We were testing whether China's official company registry could be reached, and the first reading looked clear-cut. A paired control — same machine, same moment, the only variable being whether the request went through a proxy — showed the failure was in our own network path, not at the target, including for an Australian government host that answered fine on a direct connection. So we withdrew the conclusion and published the correction.

That set how the desk works: state the vantage point, state the date, state what the observation cannot support. Buyers who cannot check China-side records themselves are exactly the people who cannot audit an overconfident answer, so the limits have to travel with the figures.

Which are the primary technologies used for building your product?

Currawong Web's answer:

A static site with serverless functions and a serverless SQL database at the edge, with no third-party runtime dependencies in the request path. The two public tools are plain browser JavaScript — nothing is uploaded and no account is created to use them.

Registry data comes from one licensed Chinese business-information platform. We do not query, proxy, embed or scrape the official government portals from a buyer's browser, and we do not work around access controls on them; when an official source has to be read, a person in China reads it and reports the source, the query date and the limits.
