flatpass VS cppq

• Automatic role assignment
  Members pay, the bot grants their Discord role instantly. A buyer who isn't in your server yet is added with it. No manual verification.
• Automatic role removal
  The role comes off when a subscription ends, is refunded or charged back. It stays while Stripe retries a failed renewal.
• Hosted invite page
  A subscription page in your server's own look (name, icon and colours) builds itself from your roles and pricing. No code.
• Price card in Discord
  Post a card in any channel and pin it: each plan gets a button with its price, and the card updates when you change one.
• Checkout links
  Every plan has its own link that opens checkout directly, for your website, bio or anywhere else you post.
• Invite Page Analytics
  Visitors, page views, clicks on your checkout links and conversion rate, by referral source, region and device, plus taggable campaign links to track individual shares.
• 0% of sales
  Never a percentage cut. You keep every dollar after Stripe's own processing fee.
• Flat monthly tiers
  Free up to 15 paid members. $29 up to 80 paid members, $79 up to 200 paid members, $149 for up to 750 paid members, and uncapped for $399.
• All features on every tier
  Tiers meter community size only. Nothing is gated behind a higher plan.
• Multiple tiers per server
  Run a $5 supporter role and a $25 premium role from the same server.
• Your own Stripe account
  Payments settle directly in your Stripe via Connect Standard, never a platform balance.
• Flexible biling periods
  Monthly, quarterly, every six months or yearly, each priced as you choose.
• Free trials
  Members get their role immediately, with the first charge days later. Set the length per server.
• Promo codes
  Members type a code on your invite page before checkout.
• Roles with no price
  Give a role away on sign-up. Those members never count toward the 15-member free cap.
• Cards, Apple Pay, Google Pay
  Enabled automatically through Stripe — no separate payment setup.
• Local currency checkout
  Members see and pay in their own currency where Stripe supports it.
• You own your customer data
  Emails, payment history, and the customer relationship stay in your Stripe.
• One-click OAuth, no API keys
  Authorize via Stripe Connect. flatpass never asks for or stores your Stripe secret key.
• Worldwide sellers
  EU-based, works with Stripe accounts in any country Stripe supports.
• Cancel anytime
  No setup fee, no contract. Keep access through the period you've paid for.

• 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.
