Convultra vs Self-hosted sGTM on Google Cloud or your own server
Self-hosting server-side GTM on Cloud Run, App Engine or your own server is the most controllable option there is: your cloud project, your region, your logs, no third-party processor in the path. It is also the option where the sticker price is the smallest part of the bill. This page is the total cost of ownership: instances, the engineering hours to build what a container does not ship with, and the maintenance nobody budgets for, set against a managed product with a flat plan.
Based on publicly documented features and pricing as of September 2026. Competitor pricing checked 14 September 2026. Self-hosted sGTM on Google Cloud or your own server is a good product for what it does; if any of this has changed, tell us and we will correct it.
Pick self-hosted sGTM if control is the requirement
- Compliance requires that event data never touches a third-party processor, or that you can name the region the runtime sits in.
- You have an engineer whose job includes the container, and the build of logging, retries and click ID handling is already done.
- You need arbitrary transformation, enrichment from internal APIs, or destinations no managed product supports.
Pick Convultra if the outcome is the requirement
- The $45 to $90 a month is not the cost; the engineer's hours are, and you would rather spend them elsewhere.
- You want delivery status per conversion and retries without building a logging pipeline first.
- Traffic spikes should not mean an infrastructure decision on your biggest sales day.
- You want the recovery number, revenue, ROAS and AI Attribution alongside delivery, on a flat plan.
You can run both for two weeks
Leave your current setup running and add Convultra alongside it. Shared event IDs mean no double-counting, and you get a side-by-side read on how many conversions each setup actually delivers before you cancel anything.

Is Convultra better than self-hosting sGTM?
If control is the requirement, no: a container in your own cloud project with your own region and no third-party processor is something no managed product can match. If the outcome is the requirement, accurate conversions with a delivery log and retries at a predictable price, Convultra is the better choice because the engineering hours that make a self-hosted container work are inside the plan.
How much does self-hosted server-side GTM cost?
One always-on Cloud Run instance ran about $45 a month at the time of checking. Google recommends at least two for resilience, so the practical floor is about $90, and real production environments commonly land between about $120 and $300 depending on traffic and tag load. That is before the setup day, the logging and retry work, and ongoing maintenance.
What does a self-hosted container not ship with?
A per-event delivery log, retries when a platform rejects an event, click ID persistence across sessions, and any report on what the pixel missed. Each is buildable. Each is an engineering task you own.
What is the difference between this page and the server-side GTM page?
That page asks whether server-side GTM is the right architecture at all. This page assumes you would run it yourself and totals what that costs against a managed product. If you are weighing managed hosts, the Stape and TAGGRS pages cover those.
Can I keep the container and add Convultra?
Yes. Run both with shared event IDs so Google Ads deduplicates, compare for 14 days, and keep the one that delivered more. Many teams keep the container for GA4 and use Convultra for ad conversions.
Does Convultra let me choose the hosting region?
Not on standard plans. Enterprise contracts can agree a processing region. If you need to name the region yourself today, self-hosting is the answer and we would rather say so than sell you the wrong thing.
