Features and specs

What each product offers, as listed by its team.

Stackless Python 5 features
Heartbeat Chat 16 features
  • Efficient Concurrency
    Stackless Python provides microthreads, also known as tasklets, which offer efficient concurrency by allowing multiple tasks to run in a single thread without the overhead of traditional threading.
  • Simplified Code
    The microthreading model can lead to simplified code when compared to multithreading, as it avoids the complexities associated with locks and synchronization primitives.
  • Improved Performance
    Due to the avoidance of context switching between OS-level threads, Stackless Python can achieve improved performance for I/O-bound applications.
  • Flexibility
    Stackless Python allows developers to pause and resume functions at almost any point, providing great flexibility for creating advanced flow control mechanisms.
  • Low Memory Footprint
    Tasklets in Stackless Python are lightweight, leading to a lower memory footprint compared to traditional threading models.

Possible disadvantages

  • Compatibility
    Stackless Python may face compatibility issues with certain Python libraries and extensions that are not designed to work with its microthreading model.
  • Limited Community and Support
    Stackless Python has a smaller user base compared to standard Python, which can result in limited community support and fewer resources for learning and troubleshooting.
  • Platform Limitations
    Some platforms may not fully support or benefit from Stackless Python's features due to differences in underlying system architectures.
  • Debugging Challenges
    Debugging can be more challenging in Stackless Python due to its non-standard execution model, requiring developers to understand its unique flow control mechanisms.
  • Maintenance and Updates
    Since Stackless Python diverges from the standard Python implementation, it may lag in adopting new features and updates present in the latest Python releases.
  • Discussions & Chat
    Threaded channels, real-time chat channels, DMs and group messages. Private channels keep paid spaces hidden from free members.
  • Courses
    Self-paced, drip or cohort-based courses with modules, quizzes, assignments and progress tracking. Every lesson has its own discussion.
  • Events
    Live events and workshops with RSVPs, reminders, Google and Outlook calendar sync, recordings and recurring series. Public event pages for lead gen.
  • Voice & Video Rooms
    Drop-in live rooms for up to 256 attendees, with unlimited hours on every plan.
  • Payments & Memberships
    Subscriptions, one-time and tiered memberships on Stripe, with coupons, trials, upsells and paid waitlists. Heartbeat's fee drops from 5% to 1.25% as you move up plans.
  • Pulse AI
    AI co-builder that sets up channels, courses, offers, sign-up pages and workflows from a chat. Included on every plan.
  • Automation Workflows
    Send emails and DMs, show popups and grant access automatically when a member takes an action.
  • Landing & Checkout Pages
    Every offer gets a sign-up and checkout page. Custom AI-built landing pages: 1 on Build, 15 on Grow, 50 on Scale.
  • Documents
    Unlimited storage for resources, knowledge bases and pages of content.
  • Member Directory & Match-Ups
    Searchable member profiles, badges and gamification, plus scheduled automatic member intros.
  • Branded App & Custom Domain
    Custom domain and brand colors on every plan. Your own white-label iOS and Android app on Scale.
  • Affiliate Program
    Members earn commission for referrals, with tracking and payouts built in (Grow and Scale).
  • Analytics & Conversion Tracking
    Engagement, course and event analytics. Meta Pixel, Google Tag Manager and Google Analytics tracking on Grow and Scale.
  • Integrations & API
    Zapier (5,000+ apps), Zoom, Google Calendar and Outlook. API access on Grow and Scale.
  • Free Migration
    Move members, content and payments from Circle, Skool, Kajabi, Mighty Networks, Discord, Slack and more at no cost.
  • Pricing & Trial
    Plans from $49/mo (Build, up to 350 members), $149/mo (Grow, 5,000) and $849/mo (Scale, unlimited). 14-day free trial, no credit card.

Analysis

An editorial look at what each product does well and who it suits.

Stackless Python
Heartbeat Chat

Overall verdict

  • Stackless Python is a solid, mature alternative Python implementation that excels at massive concurrency through lightweight microthreads (tasklets), making it a good choice for specific concurrent and cooperative multitasking workloads, though its niche status means smaller community support compared to CPython.

Why this product is good

  • Provides tasklets (microthreads) that allow hundreds of thousands of concurrent tasks with very low memory overhead
  • Offers channels for clean, safe communication and synchronization between tasklets without traditional locking headaches
  • Supports cooperative and preemptive scheduling, giving developers fine-grained control over concurrency
  • Enables serialization (pickling) of running tasklets, which is powerful for saving and migrating program state
  • Proven in production at scale, most famously powering the MMO game EVE Online
  • Largely maintains compatibility with standard CPython code and libraries

Recommended for

  • Developers building highly concurrent applications requiring massive numbers of lightweight threads
  • Game servers and simulations needing efficient cooperative multitasking (like EVE Online's use case)
  • Projects that benefit from tasklet serialization for state migration or persistence
  • Systems programmers exploring alternatives to threads or async frameworks for concurrency
  • Users comfortable working with a specialized Python distribution outside the mainstream CPython ecosystem

Questions & Answers

As answered by people managing Stackless Python and Heartbeat Chat.

What makes your product unique?

Heartbeat Chat's answer:

Heartbeat was built for community as a business model. Discussions, courses, events, payments and automation were built together, so a member who buys a course can be dropped into the right channels, events and email sequence automatically, with no Zapier glue.

Your community runs on your own domain and brand, and on the Scale plan your members get your own iOS and Android app.

Pulse, our AI co-builder, takes real actions inside your community. Describe what you want and it builds the channels, courses, offers and sign-up pages. You can edit everything it makes, or skip it.

Why should a person choose your product over its competitors?

Heartbeat Chat's answer:

Every plan includes community, courses, events, payments, workflows and Pulse AI, and Heartbeat's transaction fee drops from 5% to 1.25% as you grow. Compare the total cost at your actual revenue and the difference usually shows up there.

How it stacks up against the usual alternatives:

  • Circle: similar community depth, plus Pulse AI and a fuller set of revenue tools (paid waitlists, upsells, an affiliate program, cancellation and retention flows)
  • Kajabi: community is Heartbeat's core, built alongside courses rather than added to a course platform later
  • Skool: your own domain, branding and white-label app, plus tiered memberships, cohort courses and one-time offers
  • Discord, Slack and Facebook Groups: built for paid communities, with payments, courses and member data you own

Migration from any of these is free. Our CEO, Murtaza, is still directly involved in customer support.

How would you describe the primary audience of your product?

Heartbeat Chat's answer:

People who charge for access to a community. Most fall into three groups:

  • Creators who built an audience on social platforms and want a direct, paid relationship with it
  • Coaches, educators and experts already running a business across too many tools: a course platform, Zoom, Stripe and a Facebook group
  • Organizers of professional networks, associations, alumni groups and cohort programs

Agencies also use Heartbeat to build white-labeled communities for their clients.

What's the story behind your product?

Heartbeat Chat's answer:

Murtaza Bambot (CEO) and Mayhul Arora (CTO) started Heartbeat in New York in 2020. That year, people began paying for online communities in a big way, for accountability, for learning and for time with others in their field. Most community software predates that shift. Heartbeat was designed for it, with payments in the foundation and the community as the product.

Heartbeat is backed by Mike Edelhart, Paige Craig, Maroon Alliance, Outlander and SocialStarts. More than 37,000 communities have been built on it, and builders have been paid over $27M through the platform.

The team runs its own community on Heartbeat too. It's called The Hearth, and 5,000+ builders use it to compare notes on what's working.

Which are the primary technologies used for building your product?

Heartbeat Chat's answer:

Heartbeat is a TypeScript monorepo managed with Nx.

  • Web: React
  • Mobile: React Native with Expo (iOS and Android)
  • Desktop: Electron (Mac, Windows and Linux)
  • Backend: Node.js, Express and tRPC
  • Database: MySQL on PlanetScale, with Prisma
  • Hosting: AWS, Vercel and Netlify
  • Payments: Stripe Connect
  • Real-time: PubNub

Who are some of the biggest customers of your product?

Heartbeat Chat's answer:

  • Teach For America
  • Asus
  • StreamYard
  • GirlBoss
  • NewCampus
  • MAC Enterprise Consulting
  • Power to Pitch
  • Worship Ministry Training
  • The 10K Email Club
