Presence | Maintaining a view of which users are connected, and their associated metadata, enables their online status to be updated in realtime. | Django Channels No | Rails AnyCable Yes |
Occupancy | High-level metrics about the clients currently connected to a channel make it simple to show things such as connected user count, or display which channels are the most popular. | Django Channels No | Rails AnyCable No |
Message interactions | Enables interaction with previously-sent messages, facilitating the implementation of features like message reactions and threads. | Django Channels No | Rails AnyCable No |
Message history | Enables clients to catch up on missed messages when inactive, ensuring a user doesn’t miss any important messages. | Django Channels No You would have to build message history storage and retrieval yourself, using Django's database (ORM) to store messages, and creating APIs to retrieve them. | Rails AnyCable |
Push notifications | Cross-platform push notifications make it possible to deliver important and timely messages to users even when they’re inactive. | Django Channels Yes Django Channels supports web push notifications with WebSockets. | Rails AnyCable No |
Message delta compression | Minimizes bandwidth and can reduce latency, particularly in scenarios where continuous updates are sent. | Django Channels No | Rails AnyCable No |
Programmatic management | Enables the automation of provisioning, management, and testing of service resources, simplifying integration with existing development workflows such as CI. | Django Channels Yes Django Channels can only be used programmatically. | Rails AnyCable Yes |
| Pricing | |||
Free plan | With a free plan, you can test the service’s functionality and compatibility with your project before committing to a paid plan. | Django Channels Yes | Rails AnyCable Yes AnyCable's open-source (free) version offers several out-of-the-box features, including Hotwire support, JWT authentication, consistency, and Prometheus and StatsD instrumentation. |
Pricing model | The pricing model should align with your project's expected load, usage patterns, and budget in order to be cost-effective and efficient. | Django Channels Django Channels is a free and open-source package that can be used without any cost. It's part of the Django ecosystem and doesn't have paid plans. | Rails AnyCable AnyCable has an open-source, free version, a Pro version ($1490/yr), a managed version, and a consulting version. For more information, visit AnyCable's pricing page. |
| Integrations & interoperability | |||
SDKs | Supporting multiple languages and platforms offers greater flexibility when building cross-platform realtime apps. | Django Channels Django Channels does not have any SDK. To use it, you must install it via pip as a Python package. | Rails AnyCable
|
Supported realtime protocols | Support for multiple protocols provides the flexibility to choose a protocol that best suits your project’s requirements. | Django Channels
| Rails AnyCable
|
Serverless functions | Enables integration with third-party cloud providers by facilitating the execution of custom code against messages to perform business logic like on-the-fly translation. | Django Channels None. | Rails AnyCable Supported with AnyCable's serverless library for NodeJS - more details here. |
Streaming & queueing | Provides a dependable method to reroute messages from the service to third-party streams and queues for further processing. | Django Channels Yes | Rails AnyCable Yes |

CI/CD tools | Makes it possible to provision and configure service infrastructure as part of a CI or CD pipeline, enabling repeatable and reliable deployments. | Django Channels Yes Most CI/CD tools are supported on a Django project level rather than specifically by Django Channels:
| Rails AnyCable No |
| Quality of Service | |||
Scalability | Scalability is vital as it ensures the service can handle increased data load or users without compromising performance. | Django Channels The scalability of a Django project using Channels depends your own design, implementation, and infrastructure choices. | Rails AnyCable No metrics available. |
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | Django Channels No | Rails AnyCable Yes |
Guaranteed message ordering | Maintains the sequence of messages as they were sent. This is particularly important in apps where the chronological order of messages is essential for meaningful communication. | Django Channels Django Channels guarantees message ordering in all cases. Read more | Rails AnyCable No AnyCable leverages the ActionCable protocol which does not guarantee message ordering. This is due to concurrent broadcasts. |
Exactly-once message delivery | Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages. | Django Channels No | Rails AnyCable Yes With AnyCable, you can boost data consistency from at-most-once to at-least-once and exactly-once delivery. |
| Performance & availability | |||
Uptime Guarantee | An uptime guarantee instills confidence in the reliability of the service and protects your business from the negative impacts of downtime. | Django Channels None. | Rails AnyCable No uptime SLA. |
Global edge network | By bringing servers (Points of Presence, or PoP) geographically closer to the devices of end users, and routing requests to the nearest PoP, global latency is reduced to a minimum. | Django Channels No | Rails AnyCable No |
Multi-region data replication (message durability) | By replicating data across multiple regions, the risk of data loss or downtime is greatly mitigated since if data is lost or a server fails in one region, the information can be retrieved from another. | Django Channels No Django Channels does not support multi-region data replication. It's a library for handling WebSockets, HTTP long-polling, and other protocols that require long-running connections in Django applications. | Rails AnyCable Partial AnyCable itself does not support multi-region data replication, but with the available hosting options for AnyCable, such as AWS, you can achieve multi-region data replication. |
No single point of failure or congestion | Having no single point of failure means a system is resilient and can continue to operate even if one part fails. Avoiding a single point of congestion ensures messages flow efficiently across the system and avoids bottlenecks that could lead to performance issues under load. | Django Channels No | Rails AnyCable Yes |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | Django Channels Unknown. | Rails AnyCable Unknown. |
| Security & compliance | |||
API key authentication | Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens. | Django Channels No | Rails AnyCable No |
Token-based authentication | Provides a means to securely authenticate user devices against your user management system. | Django Channels Yes Read more | Rails AnyCable Yes Supported with JWTS. |
Single Sign-On (SSO) authentication | SSO streamlines login processes, boosts security by minimizing password use, and meets compliance needs for secure data access management. | Django Channels No Django Channels itself does not natively support Single Sign-On (SSO). SSO is typically handled at the Django application level. | Rails AnyCable No |
Rules for permissions and operations | Provides control over which users can subscribe and publish to certain channels. | Django Channels No | Rails AnyCable Partial AnyCable doesn't have built-in features for managing permissions and operations. These are typically handled at the application level using Rails' authorization mechanisms or by integrating with other frameworks or services. |
End-to-end encryption | Ensures that the data transmitted between the client and the API server remains confidential and secure while in transit. | Django Channels No | Rails AnyCable No |
Encryption at rest | Ensures data stored by the service is secure and compliant, while also mitigating the risks of a data breach. | Django Channels No | Rails AnyCable No |
