Presence | Maintaining a view of which users are connected, and their associated metadata, enables their online status to be updated in realtime. | AWS AppSync Partial "AWS AppSync does not provide events related to client connections or disconnections" (see source) - but it can be built on top of it by composing multiple AWS products. | Supabase Realtime 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. | AWS AppSync No | Supabase Realtime Yes Supabase Realtime's Presence feature enables occupancy tracking by allowing you to monitor user joins/leaves in channels, retrieve online user lists, and receive real-time updates on occupancy changes. |
Message interactions | Enables interaction with previously-sent messages, facilitating the implementation of features like message reactions and threads. | AWS AppSync No | Supabase Realtime Yes Supabase enables message interactions using Presence for tracking, Postgres Changes for listening to changes, and Broadcast for custom events. These features can be used to build message interactions like reactions. |
Message history | Enables clients to catch up on missed messages when inactive, ensuring a user doesn’t miss any important messages. | AWS AppSync Partial Looks like you can get message history, but only in combination with other AWS services see source | Supabase Realtime No |
Push notifications | Cross-platform push notifications make it possible to deliver important and timely messages to users even when they’re inactive. | AWS AppSync Yes Find out how | Supabase Realtime |
Message delta compression | Minimizes bandwidth and can reduce latency, particularly in scenarios where continuous updates are sent. | AWS AppSync Yes See tutorial | Supabase Realtime No Supabase uses the Brotli compression algorithm for all responses, rather than delta compression. |
Programmatic management | Enables the automation of provisioning, management, and testing of service resources, simplifying integration with existing development workflows such as CI. | AWS AppSync Yes You can perform programmatic management using the AWS SDKs (Software Development Kits), AWS Command Line Interface (CLI), or infrastructure-as-code tools like AWS CloudFormation or AWS CDK (Cloud Development Kit). | Supabase Realtime 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. | AWS AppSync Yes 250,000 API requests free per month for 12 months with the AWS Free Tier. | Supabase Realtime Yes Supabase offers a free plan with the a limit of 200 concurrent clients and 100 messages per second. Read more |
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. | AWS AppSync You pay only for what you use with no minimum fees or mandatory service usage. You are billed separately for query and data modification operations, and for performing realtime updates on your data. Read more | Supabase Realtime Supabase uses a tiered pricing model based on monthly active users (MAUs):

|
| Quality of Service | |||
Scalability | Scalability is vital as it ensures the service can handle increased data load or users without compromising performance. | AWS AppSync No published metrics are available. However, this works on top of serverless technology which means theoretically it should scale to millions of concurrent connection with little to no tuning from the customer. | Supabase Realtime Supabase can handle up to 10,000 concurrent clients, 2,500 channel joins per second, and 2,500 messages per second. Read more |

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. | AWS AppSync Partial Single region by default - multi region deployment of AWS AppSync would require integration of Amazon DynamoDB Global Tables. | Supabase Realtime Yes Multi-region data replication is natively supported in Supabase through their Publications feature. Read more |
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. | AWS AppSync Partial Not available by default - but could be built with the integration of Amazon DynamoDB Global Tables. | Supabase Realtime Yes Supabase provides a globally distributed cluster of realtime servers. The realtime servers are designed to be highly available and fault-tolerant. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | AWS AppSync Unknown, although reports in forums suggest it is 200-500 ms. | Supabase Realtime Unknown. |
