IndexProbe features and specs

  • Bulk URL inspection
    Get Google's official indexation status for your whole list of URLs (sitemap, CSV, or paste) in a single analysis, instead of one URL at a time.
  • Official non-indexation reasons
    Google's exact verdict per page (Crawled – currently not indexed, Soft 404, Duplicate without canonical…), so you know why a page isn't indexed and what to fix.
  • Google crawl analysis
    30-day crawl rate, crawl frequency, and crawled / stale / never-crawled split by page segment — log-analyzer insight, with zero setup.
  • Before/after comparison
    Re-run an analysis on the same list and see exactly how each status evolved, to measure the real impact of your fixes.
  • Monitoring & regression alerts
    Automatic re-runs plus an email flagging indexation changes and crawl drops, so you act before traffic falls.
  • Multi-site / multi-client
    Track several Search Console properties in parallel — built for SEO consultants and agencies managing multiple clients.

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    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK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.

Questions & Answers

As answered by people managing IndexProbe and s3-lambda.

What's the story behind your product?

IndexProbe's answer

IndexProbe was born from a question every SEO keeps asking: "Is Google really indexing all of my important pages?" The only tool with the real answer, Google Search Console's URL inspector, works one URL at a time, which makes it impractical across a full site. Other tools fall short too: crawlers show what a site exposes (not what Google indexed), index checkers only say yes or no, and log analyzers are costly and complex to set up. So we built IndexProbe to bring GSC's official verdict to your entire list of URLs, with the speed and simplicity of a SaaS.

What makes your product unique?

IndexProbe's answer

IndexProbe is the bulk version of Google's URL Inspection tool. The GSC inspector gives you Google's real, official verdict, but only one URL at a time. IndexProbe runs that same inspection across your whole list of URLs in a single analysis, so you see what Google actually decided for every page: its indexation status and, if it's not indexed, the official reason (Crawled – currently not indexed, Soft 404, Duplicate without canonical…), plus the canonical Google chose and the last crawl date. No crawling, no sampling, no binary indexed / not indexed.

Why should a person choose your product over its competitors?

IndexProbe's answer

  • vs the GSC URL inspector — the same official verdict, but on your whole list, filterable, exportable and repeatable, instead of one URL at a time.
  • vs index checkers — they tell you if a page is indexed; IndexProbe tells you why it isn't, so you know what to fix.
  • vs SEO crawlers — they see what your site exposes; IndexProbe sees what Google decided.
  • vs log analyzers — Google crawl data (rate, frequency, by segment) with zero setup, at a fraction of the cost.
  • Plus a before/after Comparison, automated monitoring with regression alerts, and multi-site / multi-client support.

How would you describe the primary audience of your product?

IndexProbe's answer

  • SEO consultants and agencies tracking indexation across multiple sites and clients in parallel.
  • In-house SEO and marketing teams running a content-heavy or large site.
  • Anyone who needs Google's official indexation data across all their strategic pages, from a few hundred to 100k+ URLs, without inspecting them one by one.

Which are the primary technologies used for building your product?

IndexProbe's answer

  • Next.js (React, TypeScript), hosted on Vercel
  • Tailwind CSS, PrimeReact and Recharts for the UI and data visualizations
  • Supabase (PostgreSQL + auth)
  • Stripe (billing), Resend (email), PostHog (analytics)
  • Core data from the official Google Search Console API
