Astronomer vs Segment: What are the differences?

Astronomer: Capture every user event and route them anywhere. Automatically. Astronomer is a data engineering platform that collects, processes and unifies enterprise data so you can get straight to analytics, data science and insights. Astronomer Clickstream captures valuable user events and routes them straight to all your favorite tools or a data warehouse for analytics. All in real time; Segment: A single hub to collect, translate and send your data with the flip of a switch. Segment is a single hub for customer data. Collect your data in one place, then send it to more than 100 third-party tools, internal systems, or Amazon Redshift with the flip of a switch.

Astronomer and Segment can be primarily classified as "Analytics Integrator" tools.

Some of the features offered by Astronomer are:

  • VPC Deployment - Control your infrastructure on your private cloud
  • Real-time monitoring - See for yourself that your data is flowing smoothly
  • Robust library - and when you need a new connector, just ask

On the other hand, Segment provides the following key features:

  • A single API to integrate third-party tools
  • Data replay that backfills new tools with historical data
  • SQL support to automatically transform and load behavioral data into Amazon Redshift

This is a question for best practice regarding Segment and Google Tag Manager. I would love to use Segment and GTM together when we need to implement a lot of additional tools, such as Amplitude, Appsfyler, or any other engagement tool since we can send event data without additional SDK implementation, etc.

So, my question is, if you use Segment and Google Tag Manager, how did you define what you will push through Segment and what will you push through Google Tag Manager? For example, when implementing a Facebook Pixel or any other 3rd party marketing tag?

From my point of view, implementing marketing pixels should stay in GTM because of the tag/trigger control.

If you are using Segment and GTM together, I would love to learn more about your best practice.

Hello Iva,

I think it is a good exercise to think about this framework once you start to add tags, triggers, and parameters and connect data between different tools (Amplitude, Google Ads, Linkedin Ads, Twitter Ads). I really love a post where Daniel Wolchonok shared a video about the Data Stack at Reforge ( My suggestion and what I see in other startups, centralise everything in one platform, Segment, and then send data whatever you need. Allow Google Tag Manager to be the tool for marketers and don't allow them to use Segment (I am a marketer). It is good that marketers have the freedom to set up tags and triggers for conversions and audiences but it is good that they don't have access to everything. So, I found it very simple to do it that way, Segment for everything and then connect Segment with Google Tag Manager where Google Tag Manager will allow marketers to work on the events, conversions, tracking, pixels, etc.

I hope you find this helpful. I will try to work on creating basic documentation to collect all of that information. I found really interesting for many startups at the beginning.
