Send push notifications straight to your audience's lock screen without building an app. PushPass uses Apple Wallet and Google Wallet passes to deliver instant, clickable messages that land right alongside boarding passes and payment cards. No app download. No opt-in friction. Just direct access to the most valuable real estate on your customer's phone.

Every pass lives permanently in your subscriber's digital wallet, keeping your brand visible every time they scroll past. It is always there, always on, and impossible to bury in a cluttered inbox or an unread notifications panel.

Each pass comes with a built-in QR code that turns every subscriber into a distribution channel. Fans share by letting friends scan their pass in person, or you print the code on packaging, merch, signage, or receipts. Growth happens organically without ad spend.

PushPass also includes a full loyalty and rewards system out of the box. Track visits, purchases, or engagement milestones and reward your best customers directly through the pass. No third party loyalty plugin required.

Additional features include real time analytics, custom branded pass designs with your logo and colors, geo-targeted messaging, subscriber segmentation, and scheduled campaigns. The platform supports unlimited passes across multiple brands from a single dashboard.

Pricing starts at $44.99 per month with your first 2,000 subscribers included, scaling affordably as you grow. No contracts, no setup fees.

PushPass works for creators, artists, restaurants, retail brands, event organizers, and any business that wants a direct, owned communication channel that doesn't depend on algorithms or social platforms.

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.

Questions & Answers

As answered by people managing FanCircles and s3-lambda.

Why should a person choose your product over its competitors?

FanCircles's answer

FanCircles is a strong choice for anyone who wants a direct, predictable way to reach their audience without building a mobile app or fighting platform algorithms. Unlike traditional loyalty systems, FanCircles wallet passes support real-time push notifications, making them useful not just for rewards, but for communication, reminders, launches, and sales.

The platform is designed to grow with you. Pricing scales based on the number of pass holders, so it works just as well for a small creator as it does for a large brand. The built-in pass designer makes it easy to create branded wallet passes, while the API and automation tools allow more advanced teams to integrate FanCircles into their existing workflows.

Most importantly, FanCircles gives businesses ownership of their audience relationship. The wallet pass lives on the customer’s phone, not inside a social network or inbox, creating a more durable and dependable connection over time.

What makes your product unique?

FanCircles's answer

FanCircles is unique because it combines wallet passes, push notifications, and digital loyalty into a single, app free platform. Instead of asking users to download an app or rely on email and social media, FanCircles uses the mobile wallet that already exists on the phone.

Each wallet pass acts as a branded loyalty card, membership card, or access pass, while also enabling instant push notifications. Fans opt in once by adding a pass, and from that point on can receive timely updates, offers, and reminders directly on their device.

FanCircles also emphasizes first party data ownership, flexible pricing that grows with you, and automation. Businesses can design their own passes, send notifications manually or via API, and scale usage as their audience grows. The result is a practical, reliable communication channel that works alongside existing marketing tools rather than trying to replace them.

How would you describe the primary audience of your product?

FanCircles's answer

FanCircles is built for creators, brands, artists, and businesses that want a direct and reliable way to reach their audience without relying on social media algorithms or mobile apps. The primary audience includes creators and artists, marketing teams, agencies, ecommerce brands, and organizations that already understand the value of first-party data and ongoing customer relationships.

These customers are typically running email marketing, paid ads, or loyalty programs and are looking for a complementary channel that delivers instant visibility. They use FanCircles wallet passes and digital loyalty cards to send push notifications, share timely updates, promote offers, and build long-term loyalty through a pass that lives on the customer’s phone.

FanCircles appeals to teams that value simplicity, scalability, and ownership. Whether starting with a small audience or managing large volumes of pass holders, customers choose FanCircles because it grows with them, requires no app download, and fits cleanly into existing marketing and operational workflows through APIs and automation.

Who are some of the biggest customers of your product?

FanCircles's answer

Universal Music Group Warner Music Group Sony Music Creative Artists Agency (CAA) United Talent Agency (UTA)

    · CEO at Zoobu ·
    Great for brands using influencers.

    We use influencers, and this has been amazing at converting QR code viewers into persistent connections. We can now send notifications directly to users without them having to install an app, which I didn't think was even possible. Before taking a look at FanCircles PushPass platform.

    Competitors: Loyalty
  2. Didn’t expect this to work so well!
