Google Tag Manager alternatives: where to go and how to switch without losing data

Why switch to Stape. Stape doesn't replace GTM. It hosts your server container for you. Your tags stop firing from the browser straight to Google, Meta or TikTok; they go to your own subdomain first, which forwards them. You get fewer blocked requests, first-party cookies set by your domain, and a lighter page. Your configuration stays, and so does everything your team already knows.

Who it's for. Ecommerce brands and small teams losing ad conversions who don't want to manage a Google Cloud project.

Who it's not for. Anyone trying to get out of the Google ecosystem: you're still on GTM, with its logic and its limits.

The catch. You pay for requests hitting the server, not for sales. Overage rules are strict. On Free, the container is switched off until you upgrade. On Pro, it pauses at 110% of your quota with no grace period. Only Business and up get a 30-day grace period, and only once. A few user reviews also mention errors that are hard to fix without technical skills, and a forecast cost that kept climbing with traffic.

Pricing. Free: 10,000 requests a month. Pro: $20 a month ($17 billed yearly) for 500,000 requests. Business: $100 ($83 yearly) for 5 million requests and 20 domains. Enterprise: $200 ($167 yearly) for 20 million. Above that, a Custom plan with SSO and a HIPAA BAA.

How to migrate. Create a server container in GTM, paste its config into Stape, point a subdomain (say, data.yoursite.com) at it, then send your web container's hits to that subdomain. Tip: watch your usage for two weeks on the free plan before you pick a tier, and leave headroom. A paused Pro container means a hole in your data.

Why switch to Zaraz. Zaraz loads your third-party tools from Cloudflare's network (at the edge) instead of inside your visitor's browser. Your pages ship far less JavaScript. If your domain already sits behind Cloudflare, you turn it on from the same dashboard, with no new vendor to onboard.

Who it's for. Sites already on Cloudflare, and teams whose top priority is page speed.

Who it's not for. A site that isn't on Cloudflare: you'd have to move your whole domain first. Also a team that relies on a long list of ready-made integrations, because Zaraz's catalog is shorter than GTM's.

The catch. The free million events is per account, not per site. Without a paid plan, Zaraz stops once you hit that million and stays off until the next cycle. Your tracking goes dark with no warning to anyone.

Pricing. One million events a month free, then $5 per extra million. On a developer forum, one startup said it pays around $20 a month for Cloudflare in total, Zaraz included (its founders are ex-Cloudflare, worth knowing).

How to migrate. Add each tool from the Zaraz catalog one by one, copying IDs from your GTM tags. Move to a paid plan before your traffic gets near the million-event line.

Why switch to Segment. A tag manager fires a separate script per tool. Segment flips the model: your site sends each event once, and Segment forwards it to your analytics, ad platforms, CRM and warehouse. For a product team that keeps adding tools, that's fewer scripts on the page and one clean definition of every event.

Who it's for. SaaS and product teams with developers, who want the same events in five or ten tools.

Who it's not for. A marketing team that wants to add a pixel without touching code: Segment needs engineering time to instrument events properly.

The catch. It's not a drop-in tag manager, and the bill follows your monthly tracked users. The free plan covers 1,000 of them; the Team plan starts at $120 a month. Plenty of teams eventually leave Segment over cost, which is why we wrote a separate guide on switching from Segment.

Pricing. Free up to 1,000 monthly tracked users. Team from $120 a month.

How to migrate. Write a tracking plan first: every event, its name, its properties. Then instrument it in your code and connect destinations one at a time, keeping GTM running until each one matches.

Why switch to Matomo Tag Manager. It's the most direct route if you're leaving Google Analytics as well. The tag manager is built into Matomo, it's open source, and it's free with no limits when you install it on your own server. Your data stays with you, which makes privacy reviews a lot shorter.

Who it's for. Public sector, nonprofits, universities, and companies that want to own their data and have someone to run a server.

Who it's not for. A growth team living in Google Ads that adds a new pixel every week: the catalog is shorter and there's no community template gallery.

The catch. Matomo says so itself: no templates, no folders, no workspaces, and around 20 tag types against more than 50 in GTM. There's no container import, so everything is rebuilt by hand. And check the hosting: Matomo Cloud runs on AWS, so a European vendor doesn't automatically mean non-US infrastructure.

Pricing. Matomo On-Premise is free. Matomo Cloud is paid by monthly traffic, with a free trial and no credit card required, and up to 30 tag containers. Check the vendor's page for the price at your volume.

How to migrate. Rebuild variables first, then triggers, then tags, following your GTM inventory. On the Matomo forum, one user mid-migration saw very different numbers depending on whether hits went through Matomo Tag Manager or GTM, up to two or three times more on one side. Run both in parallel and explain every gap before you turn GTM off.

Why switch to Piwik PRO. With GTM you glue three pieces together: GA4 for measurement, GTM for tags, and a separate consent platform. Piwik PRO puts all three in one interface, and consent directly controls which tags fire. That removes one of the most common mistakes: a tag that fires before the visitor has made a choice.

Who it's for. Healthcare, banking, insurance and government teams that have to prove exactly what they collect.

Who it's not for. A small store moving three pixels. The suite is broader than the need, and so is the price.

The catch. The official pricing page only lists the top tiers: Enterprise from $25,000 a year and Healthcare from $30,000 a year. For anything smaller, you have to ask sales. Tags get rebuilt, as everywhere else.

Pricing. Enterprise from $25,000 a year, Healthcare from $30,000 a year. Smaller offers aren't priced on the official page: ask for a quote with your monthly action count.

How to migrate. Set up the consent module first, then the tag manager, then analytics. Keep the same event names you used under GTM so your reports stay comparable and you touch less site code.

Why switch to Tealium iQ. Once a brand runs dozens of sites, several agencies and a data team, free GTM starts to creak: three workspaces, permissions that are too broad, no service commitment. Tealium iQ is built for that setup, with separate environments, fine-grained permissions, a standardized data layer and vendor support.

Who it's for. Large retailers, telecoms, banks and media groups with an annual budget and a team to run the project.

Who it's not for. A small or mid-sized business: the onboarding project and the contract are far bigger than the need.

The catch. There's no public price for iQ. Everything goes through sales, and the rollout is measured in months. Adobe Experience Platform Tags plays a similar role if you already pay for Adobe Experience Cloud.

Pricing. Quote only.

How to migrate. It's a project, not an import. Define your target data layer first, then have the integrator or Tealium's team rebuild the tags. Write a parallel-tracking period into the contract.
