Performance, reliability, scalability, and messaging guarantees

Before considering anything else, you need to trust your realtime collaboration platform provider can deliver a dependable user experience at scale. Performance, reliability, scalability, and superior messaging guarantees are critical factors for any solution that enables the building of collaborative applications. These characteristics directly impact the user experience and can make or break the success of any realtime collaborative experience.

Realtime collaboration features

End-users are coming to expect a number of core features to facilitate ‘in-app’ collaboration and enhance the team-work experience - live avatar stacks, live cursors, live locations, live updates, field locking, annotations, comments, notifications and more.

You’ll want to make sure the platform you choose provides the functionality you need without being too prescriptive in what you can build.





Essential magic ingredient of a number of collaborative features.

Ably’s presence feature allows you to be aware of other clients that are currently “present” on a channel, synchronizing online user state across devices.

It supports a configurable number of presence members and supports 200 members by default, with many more upon request.

Ably automatically deals with connection states of clients. If I disconnect it will automatically tell people “I am no longer here.”

Member state updates such as GPS device location are supported.

Platform efficiencies gained through support of granular presence subscriptions.

Presence Docs

Presence feature represents people’s movements and actions inside ‘the room’. People in the room are able to see what others are doing in real-time.

Only up to 30 as standard.

Don't allow for more granular subscriptions to avoid unnecessary messages.

Can’t find documentation on whether or not Liveblocks automatically deals with connection states.

Flexible pub/sub messaging


Ably offers reliable, low-latency pub/sub messaging that can enable serverless communication - with guaranteed message delivery.


Liveblocks has a broadcast capability, which can be used to broadcast events to notify in real‑time other connected clients to the room.


We retain two minutes of message history as a default, so if clients disconnect they can properly catch up upon reconnection. Useful for chat or live feeds. You can choose to persist the last message for up to 365 days. Persisted messages retain ordering.

We also enable customers to plug in their own database to get messages beyond what’s retained in our history.

History docs

Instead of history Liveblocks have an ‘Undo/redo’ capability for previous actions. We have been unable to identify from their website, how far back you can apply this (how many edits back).

Liveblocks provide their own persistent storage.

Channel rewind & persistence

Channel rewind and persistence simplify the problem of joining a collaborative session “late” and needing to catch up on edits.

Persistence & rewind docs

Instead of channel rewind Liveblocks have an ‘Undo/redo’ capability for previous actions. We have been unable to identify from their website, how far back you can apply this (how many edits back).

Liveblocks provide their own persistent storage.

Connection state recovery

Automatic reconnection and event replay ensure a good user experience through connectivity blips and avoids unnecessary reads. On disconnect we automatically keep state and retry connection every 15 seconds for two minutes. Once the connection is re-established, any missed messages will be sent to the client.

Connection State Recovery Docs


We have not identified any documentation that indicates whether Liveblocks supports connection state recovery.

Push notifications

Send push notifications directly to collaborator's devices, regardless of whether they are currently active in the app or not.

Push notifications docs


Can’t find documentation on whether or not Liveblocks supports push notifications.

Message interactions

Makes it very easy to interact with messages previously sent to a channel. This comes in handy if you’re building in a comment feature where users can interact with a message – for example by ‘liking’, replying, quoting, or adding an emoji reaction.

Message interactions docs


Can’t find documentation on whether or not Liveblocks supports different message interactions.

Conflict‑free data types


Avoid conflicts through field locking, using presence. Enables multiple users to edit the same document at the same time - locking cells, fields, sections.


Use conflict‑free data types to enable people to edit the same document in real‑time.

Liveblocks automatically resolves the conflicts.

The Ably protocol, which is used for realtime communication between the Ably servers and client SDKs is WebSocket-based. Note that we offer fallback transports such as XHR Streaming and XHR polling, for environments where WebSockets aren’t supported.

We believe interoperability is key, so we also support additional protocols:
- Server-Sent Events

Explore the protocols supported by Ably

Liveblocks is WebSockets based and doesn’t support any other messaging protocols, such as MQTT, SSE, or AMQP.

Security and compliance

Security and compliance are front of mind for many collaborative use cases. Encryption, authentication, roles and permissions, and compliance with standards like SOC 2 are essential requirements for any collaborative multiplayer solution.





TLS encryption.

256-bit AES encryption using private keys. This way, message payloads are opaque, can never be decrypted by Ably, and can only be decrypted by other clients that share your secret key (end-to-end encryption).  

Learn more about Ably's encryption


Can’t find documentation on whether or not Liveblocks supports TLS/SSL and AES-256 encryption.



Ably authentication capabilities:
- API keys (basic authentication). Recommended to be used server-side. 
- Tokens with fine-grained access controls for the client-side. Note that Ably supports ephemeral & revokable tokens, and JWTs. 

Learn more about Ably’s authentication mechanisms


Tokens - configurable through choice of Next.JS, Firebase, NuxtJS, Express.

Configurable chat roles & permissions


Ably allows you to set various permissions for API keys and tokens (e.g., right to subscribe to channels and presence events, right to publish, right to retrieve message history).

Explore Ably's configurable rules and permissions


Rooms can have different permission types assigned at three different levels: default, groups, and users.


SOC 2 Type 2, HIPAA, GDPR, EU and US-only data storage.

Learn more about Ably’s security and compliance

SOC 2 coming soon.

Data governance

Data governance is not a concern with Ably. We only store data such as chat messages for short periods of time (2 minutes in case persistent data isn’t enabled, and up to 72 hours if it is enabled). 

We offer integrations with tools like Kafka, Amazon Kinesis, Amazon SQS, and we support queues and webhooks, so you can easily move your chat data into your own long-term storage, and govern it as you see fit. 

Have to use Liveblocks data store.

Enterprise customers can request a Data Processing Agreement (not available for other tiers).
