I built OutageDeck because I got tired of opening a dozen status pages whenever something broke, trying to work out whether the problem was mine or somebody else's.

OutageDeck reads the official machine-readable status feeds cloud and SaaS vendors publish about themselves. It normalizes current state, affected services, incident updates, and source timestamps into one stack view.

The boundary matters. A vendor feed is not independent truth and can acknowledge an incident late. OutageDeck is an index and a second signal, not a replacement for direct provider checks or synthetic probes from your own regions. Every record links back to the official source. OutageDeck's own health endpoint is also checked from a separate GitHub-hosted workflow, with public run history at https://github.com/outagedeck/status-check/actions/workflows/outagedeck-health.yml.

You can check a stack without an account. Free accounts add email alerts for five providers. Paid plans start at $19 a month and add Slack, Teams, Discord, webhooks, unlimited providers, and private Statuspage or Instatus feeds.

Incident history stays available after the vendor removes its banner. Developers can use the keyless JSON API, OpenAPI spec, RSS feeds, README badges, CLI, MCP server, GitHub Action, and Open WebUI tool.

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.

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 OutageDeck and s3-lambda.

Which are the primary technologies used for building your product?

OutageDeck's answer

  • Frontend / app: Next.js 16 (App Router), React 19, TypeScript, Tailwind CSS
  • Data: Supabase Postgres. Every upstream feed is validated with Zod, so provider format drift fails loudly instead of corrupting data
  • Ingestion: each vendor's official feed polled every 10 minutes, with per-provider failure isolation, so one broken feed never blocks the rest
  • Alerting: a delivery ledger with exactly-once claims, so overlapping runs never double-page anyone

What's the story behind your product?

OutageDeck's answer

I got tired of opening a dozen vendor status pages during every incident, just to work out whether the problem was mine or somebody else's. So I built the thing I wanted.

It launched in July 2026 as one live board over the official status feeds of cloud and SaaS vendors teams depend on. The catalog changes as official sources are added or removed.

The rule from day one: official machine-readable sources only. No crowd reports, no scraping. If a status can't be traced back to the vendor's own feed, it doesn't get published.

How would you describe the primary audience of your product?

OutageDeck's answer

Anyone whose incident channel regularly starts with "is AWS down, or is it just us?":

  • DevOps, SRE, and platform engineers. Answer "is it us or them?" in seconds during an incident.
  • Small SaaS teams. Your uptime depends on other people's clouds, so see whether a vendor has acknowledged a problem before changing your own stack.
  • Agencies and MSPs. Watch the vendor stacks of many clients from one place.

Why should a person choose your product over its competitors?

OutageDeck's answer

Choose it when your problem is third-party vendor status, not when you need synthetic monitoring of your own application.

  • Fast triage. One stack view normalizes current status, affected services, source timestamps, and incident history across the cloud and SaaS vendors your product depends on. You can use it without an account.
  • Traceable, limited claims. Every record links to the vendor's official source. Providers can acknowledge incidents late, so OutageDeck should be a second signal beside direct provider checks and probes from your own regions. Its own health endpoint is checked from a separate GitHub-hosted workflow with public run history.
  • Useful exits. Free accounts add email alerts for five providers. Paid plans add Slack, Teams, Discord, webhooks, and private Statuspage or Instatus feeds. Developers can use the keyless JSON API, RSS, badges, CLI, MCP server, GitHub Action, or Open WebUI tool.

What makes your product unique?

OutageDeck's answer

OutageDeck only reports what vendors officially publish. Every status comes from the provider's own machine-readable feed, never crowd reports and never scraping. Then it holds vendors to what they said:

  • Observed uptime history from archived vendor-published status, with honest partial and regional impact framing
  • Every incident links back to its source on the vendor's own status page
  • One dashboard for the cloud and SaaS vendors your product depends on, with alerts to Slack, Teams, Discord, email, or webhooks
  • Bring your own feed on paid plans: point it at any Statuspage or Instatus page it does not track yet
  • A JSON API, RSS feeds, README badges, and an MCP server so a coding agent can check the vendor before it blames your code
