“The documentation is overall disappointing. The API reference, some comprehensive FAQs, and some decent writing for SDK-specific guides are noteworthy highlights. However, the rest is not great. There is no navigation sidebar; all the various sections of the docs are individual articles that are listed on a menu page. Furthermore, the sections are not organized in a logical manner; it’s unclear where to start, and often hard to understand how the topics connect. There are only a few GitHub tutorials, with some brief steps, but certainly not enough details. Overall, you get the feeling the documentation fails to deliver relevant bits of information, and getting started with Kaazing was far from easy.”

The documentation is quite comprehensive and well detailed, with easy access to code samples while you read through it. There are quickstart tutorials for all the products using different SDKs. However, I feel some developers may get lost while trying to find references or while trying to navigate the various pages, especially around the API reference.

The dev console allows you to manage and configure all things Twilio. This includes SMS, Chat, Notify, Sync, Voice, Video, etc. The stats and reports gives its users a general overview of what goes on with their account. This includes API accessed, cost, exact time of access. Besides the general overview, I like the fact that every product has its page where users can view a better breakdown of the activities. I also like that activities are being viewed in monthly ranges. This means you get a detailed report for activities in a month. This way, the report isn’t clumsy or cumbersome.

“Kaazing offers SDKs in several different programming languages, and for different operating systems. The naming conventions make the APIs reasonably intuitive and simple to understand, and the extensive API references help a lot. The APIs are mostly consistent at a class level, which makes sense, since the WebSocket ones are basically modeled around the standard WebSocket API. Note that the client SDKs also provide additional protocol capabilities, such as AMQP and JMS, which is quite useful.”

The Twilio API is well structured, intuitive, and consistent across all SDKs. The methods are also easy to understand. The documentation provides different pages for each programming language and platforms, making it easy to set up on the backend server for production use with different platforms.
Kaazing WebSocket Gateway
|"Hello world" code example|
Kaazing WebSocket Gateway
Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages.Explore Ably's pub/sub messaging implementation
A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer).Explore Ably's message queues implementation
Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games.Explore Ably's presence implementation
Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere.Explore Ably's message history implementation
You can configure Kaazing WebSocket Gateway to hold recent messages for a topic in a last value cache. However, you are required to use a JMS-compliant message broker, such as RabbitMQ.
The maximum message retention duration is 13 months. In October 2020, this was one of three key changes Twilio made in the way it stores message records:
1. Message log history will only be available from the last 13 months via Twilio Console and the Messages API Resource. Messages logs older than 13 months will still be accessible via the Bulk Export API, or the Bulk Export Message Log Archives in Console.
2. All Media Objects (e.g. MMS and WhatsApp message file attachments - pictures, audio, etc.) from Messages older than 13 months will be permanently deleted.
3. Deleting a Message log will also automatically remove any Media objects associated with that message.
This applies to all Twilio products.
Connection state recovery (stream resume)
In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off.Explore Ably' s connection state recovery implementation
Guaranteed message ordering
Ordering ensures that messages are delivered to consumers in the same order that producers publish them.Explore Ably' s guaranteed message ordering implementation
Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once.Explore Ably' s idempotent publishing implementation
Message delta compression
Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages.Explore Ably' s message delta compression implementation
Native push notifications
Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts.Explore Ably's push notifications implementation
Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP.Explore Ably's webhooks implementation
A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels.
Note that serverless functions are usually fully managed by cloud vendors.Explore Ably's serverless functions implementation

API key authentication
The simplest way to authenticate. Involves using private API keys that you can usually create and edit via a dashboard. Recommended to be used server-side, as private API keys shouldn’t be shared with untrusted parties.Explore Ably's implementation of API key authentication
Which popular token-based authentication mechanisms do Kaazing WebSocket Gateway and Twilio support?
Note that token-based authentication is usually the recommended strategy on the client-side as it provides more fine-grained access control and limits the risk of credentials being compromised.Explore Ably's implementation of token-based authentication

|Pricing & Support|
What do the free packages offered by Kaazing WebSocket Gateway and Twilio consist of?Explore Ably's free package for our pub/sub messaging platform
On Twilio Sync, your first 200 endpoint-hours for each month are free:
“Endpoints are unique devices or browser tabs and are counted once for each wall-clock hour during which they interact with Sync. Each unique endpoint will incur charges of at most $0.01 per calendar day.”
Users also get free access to their first 10,000 actions each month:
“Actions are defined as incoming requests from your application that read and write data. Resulting webhooks, updates to connected endpoints, and storage are included in the cost of an action.”
How are the Kaazing WebSocket Gateway and Twilio pricing models calculated?Explore Ably's pricing model for our pub/sub messaging platform
Pricing varies on what service you intend to use.
Specifically for Twilio Sync, the pay-as-you-go model is employed and pricing depends on the endpoint-hour. Here is the breakdown:
Accessing 201 and 12,000 endpoint-hours costs $0.00250/endpoint-hour
Once the 12,000 endpoint-hours threshold is crossed, users begin to pay a lesser amount. Between 12,001 and 72,000 users pay $0.00200/endpoint-hour

“Kaazing is present on a few platforms, such as StackOverflow, Gitter, and GitHub. However, all discussions and GitHub issues seem to date back from 2018. All in all, there’s nothing to indicate Kaazing has an active and thriving community. There only seem to be a few projects made by the community, and almost no community-made content (blogs, tutorials).”

Twilio has moderate online presence. I could not find an online presence on Slack, but I was able to find Twilio-related engagements on Discourse and Stackoverflow. There are other recognized channels like Twilio Developer Community, and Twilio on Dev.to, where Twilio organizes hackathons and where you can find tutorials. The community there is active and generates content like new projects, articles, and answers to questions. You are likely to get or find an answer to your question, regardless of how complex it is. Twilio repositories have over one thousand stars on GitHub.
