Google Analytics 4 is free, powerful, and deeply connected to Google's advertising ecosystem.
It's also a lot of analytics platform for a website owner who mainly wants to answer a few fairly straightforward questions:
Where did my traffic come from? Which campaign sent it? Did those visitors convert? And which sources are actually worth more attention?
I've used Google Analytics professionally for years, going back well before GA4. I don't think GA4 is a bad product. I do think it's become easy to confuse having more analytics capability with having better answers.
For a lot of marketing sites, GA4 may simply be more machinery than the job requires.
So I went looking for free alternatives with a specific goal in mind: traffic and campaign attribution.
Not just pageview counters. Not enterprise attribution suites that cost thousands of dollars. I wanted tools a small business, marketer, publisher, or site owner could realistically use to understand where visitors came from and what happened after they arrived.
Five stood out:
- Umami
- Matomo
- Plausible Community Edition
- PostHog
- Cloudflare Web Analytics
They're not interchangeable, and "free" means something different with each one. That's where this comparison gets interesting.
Quick comparison
| Platform | Free option | UTM tracking | Conversion tracking | Attribution depth | Best fit |
|---|---|---|---|---|---|
| Umami | Free cloud tier + free self-hosted | Yes | Yes | First-click and last-click | Marketing and content sites |
| Matomo | Free self-hosted | Yes | Yes | Last non-direct by default; advanced multi-attribution is premium | Closest GA4 replacement |
| Plausible CE | Free self-hosted | Yes | Yes | Campaign and goal focused | Simple privacy-first analytics |
| PostHog | Generous free cloud tier | Yes | Yes | Strong behavioral and product analysis | SaaS and product teams |
| Cloudflare Web Analytics | Free | Basic source/referrer visibility | Limited | Basic traffic-source analysis | Traffic and performance monitoring |
If I were choosing strictly for free marketing attribution on a normal website, I'd start with Umami.
If I wanted something much closer to the depth of Google Analytics and didn't mind running it myself, I'd look hard at Matomo.
Here's why.
1. Umami: my pick for most marketing sites
Umami surprised me.
I originally thought of it as one of those lightweight privacy analytics tools that gives you pageviews, referrers, devices, and a nice clean dashboard.
It's grown well beyond that.
Umami now includes campaign UTM reporting, custom events, goals, funnels, journeys, retention, revenue reporting, and actual attribution reports. Its attribution feature can apply first-click or last-click attribution to a page or conversion event and break the result down by referrer, paid ads, and UTM data.
That's a pretty serious feature set for something that still feels considerably simpler than GA4.
What I like about Umami
All five standard UTM parameters are supported. Source, medium, campaign, term, and content can all be analyzed, which makes Umami a natural companion to the TrafficCampaign UTM Builder.
It has real attribution reporting. This is what puts Umami at the top of this list for me. You can move beyond "where did traffic come from?" and apply first-click or last-click attribution to a conversion.
Funnels and goals are built in. You can see where visitors drop out of a defined path instead of simply counting the final event.
Revenue can be connected to analytics. That's where campaign reporting starts becoming much more useful.
There's a free hosted option. Umami Cloud currently offers a completely free Hobby plan for personal projects and lower-traffic sites.
You can self-host it. The project is open source if you'd rather control the infrastructure and data yourself.
Where Umami falls short
First-click and last-click attribution are useful, but they're still fairly simple attribution models.
If you're managing complicated cross-channel customer journeys and need advanced multi-touch modeling, Umami isn't pretending to be an enterprise attribution platform.
Self-hosting also isn't really "free" in the everyday sense. The software may cost nothing, but you still need infrastructure and somebody who can maintain it.
Best for
Blogs, publishers, small businesses, agencies, lead-generation sites, and marketing teams that want useful campaign attribution without turning analytics into a second job.
My traffic attribution rating: 9/10
2. Matomo: best if you want a serious GA4 replacement
Matomo is the heavyweight of this group.
It's been around for years, was previously known as Piwik, and is probably the option I'd investigate first if someone told me:
"I want to leave Google Analytics, but I don't want to give up serious analytics capability."
The free version is Matomo On-Premise, which you install on your own server.
What I like about Matomo
It's mature. This isn't a tiny analytics experiment that appeared six months ago.
You own the data when self-hosted. For businesses that care about controlling their analytics infrastructure, that's a major advantage.
It gets much closer to GA4 feature depth. If you're used to digging into reports instead of glancing at a one-page dashboard, Matomo will probably feel more comfortable.
Its free core supports campaign tracking and goals. Matomo can process common UTM parameters, and its default goal attribution uses the last non-direct channel.
It doesn't sample your analytics data.
It can handle serious conversion and ecommerce measurement.
There's a large ecosystem around it. Matomo offers premium functionality for things like funnels, heatmaps, session recordings, custom reports, and multi-channel attribution.
Where Matomo falls short
The biggest catch is right there in the word self-hosted.
The core On-Premise product is free, but you have to install it, maintain it, secure it, update it, back it up, and provide the server it runs on.
Some of Matomo's more advanced features are premium plugins. That includes Multi Attribution, which is important if you're specifically looking for more sophisticated multi-channel attribution modeling.
So while Matomo absolutely belongs on a list of the best free GA4 alternatives, don't read "free" as "everything Matomo offers costs $0."
Best for
Businesses, technical marketers, agencies, ecommerce sites, and organizations that want analytics depth and data ownership and don't mind taking on the infrastructure.
My traffic attribution rating: 8.5/10
3. Plausible Community Edition: best if simplicity is the point
Plausible took almost the opposite approach to GA4.
Instead of giving you every possible analytics report, it tries to give you the information most website owners actually look at without burying it under layers of menus.
Traffic, sources, pages, campaigns, goals, and conversions are easy to understand.
Plausible Community Edition is open source and free to self-host under the AGPL license. The company's managed cloud service is the paid version.
What I like about Plausible
The interface is wonderfully simple. There's something refreshing about opening analytics and immediately understanding what you're looking at.
It's privacy focused and designed around a lighter analytics model.
Campaign measurement is straightforward. For a site using consistent UTMs, Plausible gives you a clean way to evaluate campaign traffic and conversions.
The tracking approach is lightweight.
It's open source.
Where Plausible falls short
Plausible's greatest strength is also the reason it ranks below Umami and Matomo for this particular comparison.
It intentionally doesn't try to be GA4.
If you want deep behavioral analysis, sophisticated attribution modeling, detailed user paths, or the kind of reporting rabbit holes GA4 makes possible, Plausible may feel limited.
And again, the truly free version requires self-hosting.
Best for
Content sites, blogs, small businesses, and marketers who mostly want to know:
Where did the traffic come from, and did it convert?
If that sentence describes 90% of what you use analytics for, Plausible deserves a serious look.
My traffic attribution rating: 8/10
4. PostHog: best for SaaS and product teams
PostHog is the odd one on this list because I wouldn't call it a direct GA4 replacement.
It's really a broader product analytics platform.
That distinction matters.
If your "website" is actually the front door to a SaaS application or software product, knowing which campaign brought somebody in is only the beginning.
You may also care about what they did after signup, which features they used, where they dropped out, whether they came back, and which behaviors correlate with becoming a paying customer.
That's PostHog territory.
What I like about PostHog
The free tier is generous. PostHog currently includes 1 million product analytics events per month in its free allowance.
It's event driven. You can analyze what people actually do inside a product rather than stopping at pageviews.
Funnels are a natural fit.
It goes far beyond analytics. PostHog also offers session replay, feature flags, experimentation, and data-warehouse capabilities, each with its own usage model.
It can connect acquisition with product behavior. For SaaS, that can be more valuable than traditional website attribution alone.
Where PostHog falls short
If you run a local landscaping company and just want to know whether Google Ads or your email campaign generated consultation requests, PostHog is probably overkill.
Its power comes with complexity.
It also includes capabilities such as session replay that deserve their own privacy review before you turn them on. More data isn't automatically better data.
Best for
SaaS companies, apps, product-led businesses, and technical teams that need to connect acquisition with what users do after they arrive.
My traffic attribution rating: 7.5/10
For product analytics, I'd rate it considerably higher.
5. Cloudflare Web Analytics: best for free basic traffic visibility
Cloudflare Web Analytics is the simplest option here.
It's free, privacy focused, doesn't use cookies or localStorage for its Web Analytics measurements, and can show useful information about traffic and real-world site performance.
Cloudflare also reports Core Web Vitals from real visitor sessions, which makes the platform particularly interesting if you care about both traffic and site performance.
What I like about Cloudflare Web Analytics
It's actually free. There's no self-hosting requirement to unlock a free software edition.
It's extremely easy to add.
Cloudflare says Web Analytics doesn't collect or use visitors' personal data.
It combines traffic visibility with real-user performance data.
You don't have to move your DNS to Cloudflare just to use it. A JavaScript beacon can be installed on sites that aren't proxied through Cloudflare.
Where Cloudflare falls short
I wouldn't choose Cloudflare Web Analytics as my primary campaign attribution platform.
That's an important distinction.
It's excellent for answering basic questions about traffic and site performance. It's much less suited to following campaign traffic through conversions, funnels, revenue, and attribution models.
Think of it as traffic analytics first.
If you need to answer:
"How much traffic did this source send?"
Cloudflare may be enough.
If you need to answer:
"Which campaign generated customers and revenue?"
I'd choose something higher on this list.
Best for
Publishers, blogs, simple websites, developers, and site owners who want lightweight traffic and performance analytics without the complexity of a full attribution platform.
My traffic attribution rating: 6/10
My simple traffic analytics rating: 9/10
Which free GA4 alternative would I choose?
For a marketing-focused website, my shortlist gets small pretty quickly.
Choose Umami if you want the best balance of simplicity, UTM tracking, conversions, funnels, revenue, and actual first-click or last-click attribution.
For most small marketing sites, this would be my first choice.
Choose Matomo if you want something closer to a full Google Analytics replacement and you're comfortable self-hosting.
Choose Plausible if you actively want less analytics complexity and mostly care about traffic sources, campaigns, and conversions.
Choose PostHog if the website is really the front door to a software product and you need to understand what users do after acquisition.
Choose Cloudflare Web Analytics if you want free, simple traffic and performance visibility and don't need serious conversion attribution.
What about GA4 itself?
I wouldn't remove GA4 just because alternatives exist.
Google Analytics still has one enormous advantage: Google.
If you're heavily invested in Google Ads, audiences, remarketing, BigQuery, or Google's broader measurement ecosystem, replacing GA4 may create tradeoffs that aren't worth it.
The tool should follow the question you're trying to answer.
Not the other way around.
One privacy warning before installing any analytics platform
"Privacy focused" isn't a magic legal shield.
Neither is "cookieless."
And self-hosted doesn't automatically mean your implementation is appropriate.
Before adding any analytics tool, understand what information it collects, whether identifiers are created, where the data goes, how long it's retained, which third parties receive it, what optional features you've enabled, and whether visitors need or should receive a choice.
We're taking a deliberately conservative approach with TrafficCampaign itself.
The site launched without GA4, Meta Pixel, session replay, or advertising trackers. We built the privacy layer first so optional analytics could sit behind consent rather than trying to bolt privacy onto the site later.
That's not legal advice. It's simply the order of operations I'm more comfortable with.
My final ranking
For free traffic and campaign attribution, here's where I'd start:
1. Umami
Best overall balance for marketing sites.
2. Matomo
Best full-featured GA4 alternative if you're willing to self-host.
3. Plausible Community Edition
Best for simple, privacy-focused campaign analytics.
4. PostHog
Best when attribution needs to connect to product behavior.
5. Cloudflare Web Analytics
Best for basic free traffic and performance analytics, but not a true attribution replacement.
The bigger takeaway is that GA4 isn't the default answer anymore.
You can choose an analytics platform based on the amount of information you actually need, how much complexity you're willing to manage, and how you want visitor privacy handled.
For me, that's progress.
And whichever platform you choose, get the campaign labeling right first. A sophisticated analytics platform can't rescue inconsistent campaign data.
Use the TrafficCampaign UTM Builder to create clean campaign URLs, then read the Campaign Tracking and Attribution Guide if you want a deeper explanation of what attribution can and can't tell you.
Frequently asked questions
What is the best free alternative to Google Analytics 4?
For straightforward marketing and traffic attribution, Umami is one of the strongest free options because its free cloud tier and open-source self-hosted version include UTM reporting, goals, funnels, revenue reporting, and first-click and last-click attribution. Matomo is a better fit when you want a deeper GA4-style analytics platform and are willing to self-host it.
Is there a free analytics platform that tracks UTM campaigns?
Yes. Umami supports all five standard UTM parameters. Matomo supports standard UTM campaign parameters as well, while Plausible Community Edition and other self-hosted analytics platforms support campaign measurement to varying degrees.
Can I replace GA4 completely?
That depends on what you use GA4 for. A content or marketing site may be able to replace it with a simpler privacy-focused platform. Sites relying heavily on Google Ads audiences, Google's advertising ecosystem, complex event analysis, or BigQuery workflows may lose capabilities by leaving GA4.
Are free privacy-focused analytics tools really free?
Some are free as hosted services up to usage limits, while others are free only when self-hosted. Self-hosting removes the software subscription but still requires hosting, updates, backups, and some technical work.
